              CONSOLIDATED AUDITED ANNUAL FINANCIAL STATEMENTS AND
                       MANAGEMENT'S DISCUSSION & ANALYSIS

A.   AUDITED ANNUAL FINANCIAL STATEMENTS

     The Registrant's consolidated audited annual financial statements,
including the report of independent chartered accountants with respect
thereto are included herein, see pages F-3 to F-38. See Note 19 of the Notes
to Consolidated Financial Statements on pages F-33 through F-38 of the
Registrant's consolidated audited annual financial statements, reconciling
the important differences between Canadian and United States generally
accepted accounting principles.

B.   MANAGEMENT'S DISCUSSION & ANALYSIS

     For management's discussion and analysis, see the Management's Discussion &
Analysis on pages M-1 through M-42 included herein.

                                   UNDERTAKING

     The Registrant undertakes to make available, in person or by telephone,
representatives to respond to inquiries made by the Commission staff, and to
furnish promptly, when requested to do so by the Commission staff, information
relating to: the securities registered pursuant to Form 40-F; the securities in
relation to which the obligation to file an Annual Report on Form 40-F arises;
or transactions in said securities.

                       DISCLOSURE CONTROLS AND PROCEDURES

     Pursuant to the Sarbanes-Oxley Act of 2002 as adopted by the U.S.
Securities and Exchange Commission, the Registrant's management evaluates the
effectiveness of the design and operation of the company's disclosure controls
and procedures (disclosure controls). This evaluation is done under the
supervision of, and with the participation of, the President and Chief Executive
Officer and the Chief Financial Officer.

     As of the end of the period covered by this Annual Report, the Registrant's
management evaluated the effectiveness of its disclosure controls. Based on that
evaluation, the President and Chief Executive Officer and the Chief Financial
Officer have concluded that the Registrant's disclosure controls are effective
in ensuring that material information relating to the Registrant is made known
to management on a timely basis, and is included in this Form 40-F.

     No change in the Registrant's internal control over financial reporting
occurred during the period covered by this annual report that has materially
affected, or is reasonably likely to materially affect, the Registrant's
internal control over financial reporting.

                        AUDIT COMMITTEE FINANCIAL EXPERT

     The Registrant's board of directors has determined that it has at least one
audit committee financial expert serving on its audit committee. Mr. Harry G.
Schaefer has been determined to be such audit committee financial expert and is
independent, as that term is defined by the New York Stock Exchange's listing
standards applicable to the Registrant. The SEC has indicated that the
designation of Mr. Schaefer as an audit committee financial expert does not make
Mr. Schaefer an "expert" for any purpose, impose any duties, obligations or
liability on Mr. Schaefer that are greater than those imposed on members of the
audit committee and board of directors who do not carry this designation or
affect the duties, obligations or liability of any other member of the audit
committee.




                                 CODE OF ETHICS

     The Registrant has adopted codes of business ethics for its employees and
officers, its principal executive officer, principal financial officer and
controller and its directors. The Registrant's codes are available on its
website at www.transcanada.com. There has been no waiver of the codes granted
during the 2003 fiscal year.

     --------------------------------------------------------------


     The nature of each category of fees is described below.

AUDIT FEES

     Audit fees were incurred for professional services rendered by the auditors
for the audit of the Registrant's annual financial statements or services
provided in connection with statutory and regulatory filings or engagements, the
review of interim consolidated financial statements and information contained in
various prospectuses and other offering documents.

AUDIT-RELATED FEES

     Audit-related fees were incurred for the audit of the financial statements
of the Registrant's various pension plans.

TAX FEES

     Tax fees were incurred for tax compliance and tax advice. These services
consisted of: tax compliance including the review of original and amended tax
returns, assistance with questions regarding tax audits, the preparation of
employee tax returns under the Registrant's expatriate tax services program and
assistance in completing routine tax schedules and calculations; and tax
services relating to common forms of domestic and international taxation (i.e.,
income tax, capital tax, Goods and Services Tax and Value Added Tax).

ALL OTHER FEES

     Fees disclosed in the table above under the item "all other fees" were
incurred for services other than the audit fees, audit-related fees and tax fees
described above. These services consisted of advice with regards to compliance
with the Sarbanes-Oxley Act of 2002.

PRE-APPROVAL POLICIES AND PROCEDURES

     The Registrant's Audit Committee has adopted a pre-approval policy with
respect to permitted non-audit services. Under the policy, the Audit Committee
has granted pre-approval for engagements of $25,000 CDN or less and within
management's annual pre-approved limit. For engagements of $25,000 CDN or less
which are not within management's annual pre-approved limit, and for engagements
between $25,000 CDN and $100,000 CDN, approval of the Audit Committee Chairman
is required and the Audit Committee is to be informed of the engagement at the
next scheduled Audit Committee meeting. In all cases, regardless of dollar
amount involved, where there is a potential for conflict of interest for the
external auditor to arise on an engagement, the Audit Committee Chairman shall
pre-approve the assignment.

     The Registrant has not approved any non-audit services on the basis of the
de-minimis exemptions. All non-audit services are pre-approved by the Audit
Committee in accordance with the pre-approval policy referenced herein.




                         OFF-BALANCE SHEET ARRANGEMENTS

     The Registrant has no off-balance sheet arrangements, as defined in this
Form, other than the guarantees described in Notes 17 and 19 of the Notes to the
Consolidated Financial Statements. The disclosure relating to guarantees in
Notes 17 and 19 to the Consolidated Financial Statements is incorporated herein
by reference.

                      GENERAL DEVELOPMENT OF THE BUSINESS

The general development of TCPL's business during the last three financial
years, and the significant events or conditions which have had an influence on
that development, are summarized below. Most of these events are discussed in
greater detail under the heading "Business of TCPL" in this AIF.

DEVELOPMENTS IN GAS TRANSMISSION BUSINESS

TCPL's focus has been to sustain, grow and optimize its natural gas transmission
business, including to pursue changes to the regulated business models that are
applicable to TCPL's operations. Summarized below are significant developments
that have occurred in TCPL's natural gas transmission business over the last
three years.

2003

In August 2003, TCPL acquired the remaining interests in Foothills Pipe Lines
Ltd. ("FOOTHILLS") that it did not previously own. The Foothills System, which
is owned by Foothills, complements TCPL's existing western Canadian facilities.
It extends 1,040 kilometres and carries over 30 per cent of all Canadian natural
gas exports to the United States.

TCPL, through Foothills, holds certificates for both the Alaskan and Canadian
segments of the Alaska Highway Pipeline Project and also holds significant
right-of-way assets for the project in both Canada and Alaska.

In June 2003, TCPL, the Mackenzie Delta Producers Group ("MACKENZIE PRODUCERS")
and Mackenzie Valley Aboriginal Pipeline L.P. ("ABORIGINAL PIPELINE GROUP" or
"APG") reached a funding and participation agreement. TCPL agreed to finance the
APG's share of project definition costs in exchange for several options
including an ownership interest in the pipeline, certain rights of first refusal
in the Mackenzie Gas Pipeline Project and the right to have the Mackenzie Delta
gas flow into the Alberta System.

In September 2003, TCPL and ConocoPhillips Company ("CONOCOPHILLIPS") announced
the Fairwinds Partnership to jointly evaluate a liquefied natural gas ("LNG")
regasification facility in Harpswell, Maine. TCPL also continues to pursue other
LNG projects in North America.

TCPL increased its ownership interest in Portland in the northeastern
United States from 33.3 per cent to 61.7 per cent through acquisitions that took
place in September and December 2003.

For further information about Gas Transmission Developments in 2003, refer to
the headings "Business of TCPL -- Gas Transmission -- Wholly-Owned Pipelines"
and "Business of TCPL -- Gas Transmission -- Other Gas Transmission" below.

2002

In August 2002, TCPL completed the acquisition of a portion of the
two per cent general partnership interest in NBP L.P., a publicly held limited
partnership which provides TCPL with a 17.5 per cent voting interest on its
partnership policy committee. NBP L.P. owns interests in pipelines and gas
processing plants in the United States and Canada, including a 70 per cent
interest in Northern Border.

                                                TRANSCANADA PIPELINES LIMITED  3

2001

In January 2001, TCPL announced that it had reached a settlement in principle
regarding 2001 and 2002 tolls and services on the Alberta System. The settlement
established the Alberta System's fixed revenue requirement for the next two
years. The settlement, approved by the Alberta Energy and Utilities Board
("EUB"), together with the receipt point specific rate design previously
approved by the EUB, formed the basis of the Alberta System's tolls in 2002.

In February 2001, TCPL announced that it had reached a settlement regarding the
2001 and 2002 services and pricing on the Canadian Mainline that resolved all
issues other than cost of capital. The parties agreed that the issue of cost of
capital would be determined in a different forum. The National Energy Board
("NEB") approved the settlement.

By December 31, 2001, TCPL had sold the majority of its natural gas marketing
and trading operations, including its structured products business, most of its
natural gas transportation and storage contracts and its net back pool
operations.

DEVELOPMENTS IN POWER BUSINESS

In the past three years, TCPL has grown its power business and in particular,
has increased its generation capacity from approximately 2,253 MW in 2001 to
4,667 MW in 2003. In addition, net earnings from power operations has increased
by $52 million over the same period. Summarized below are significant
developments that have occurred in TCPL's power business over the last
three years.

2003

In February 2003, TCPL, as part of a consortium, acquired a 31.6 per cent
interest in Bruce Power L.P. ("BRUCE POWER") and a 33.3 per cent interest in
Bruce Power Inc., the general partner of Bruce Power. Bruce Power leases its
generation facilities from Ontario Power Generation Inc. ("OPG"). The facilities
consist of eight nuclear reactors, five of which were operational at Year End
with a capacity of 3,910 MW. An additional reactor with capacity of 750 MW was
restarted in January 2004.

The members of the purchasing consortium of Bruce Power have severally, on a
pro-rata basis, guaranteed certain contingent financial obligations of Bruce
Power related to operator licenses, the OPG lease agreement, power sales
agreements and contractor services. Bruce Power continues to be operated by its
pre-acquisition management which is comprised of experienced nuclear power plant
operators. Spent fuel and decommissioning liabilities remain with OPG under the
terms of the lease.

In 2003, TCPL announced that it would construct two new power plants. The first
of these is the 550 MW natural gas-fired Becancour cogeneration power plant near
Trois-Rivieres, Quebec ("BECANCOUR PLANT") which will supply its entire power
output to Hydro-Quebec. Distribution is provided for under a 20 year power
purchase contract. The cost of the Becancour Plant is estimated to be
$550 million, including capitalized interest, and the plant is expected to be in
service in late 2006. TCPL is also constructing the 90 MW Grandview natural
gas-fired cogeneration power plant on the site of the Irving Oil refinery in
Saint John, New Brunswick ("GRANDVIEW PLANT"). Under a 20 year tolling
arrangement, a subsidiary of Irving Oil Limited will provide fuel to the
Grandview Plant and has contracted for 100 per cent of the Grandview Plant's
heat and electricity output. The cost of the Grandview Plant is estimated to be
approximately $90 million. Construction of the Grandview Plant began in 2003 and
has an expected in-service date at the end of 2004. In addition, construction of
the 165 MW MacKay River power plant was completed in 2003 and the plant is
expected to be put into commercial service in the first quarter of 2004.

2002

In November 2002, TCPL completed the acquisition of the 300 MW ManChief power
plant, situated approximately 145 kilometres northeast of Denver, Colorado. The
ManChief power plant is operated under contract by an unaffiliated third party.

4  TRANSCANADA PIPELINES LIMITED

2001

In 2001, TCPL acquired 50 per cent of the power purchase arrangements for the
Sundance B power plant located near Edmonton, Alberta. Sundance B has capacity
to generate 706 MW. In addition, TCPL completed construction of two natural gas
fired plants: an 80 MW power plant near Carseland, Alberta and a 40 MW power
plant near Redwater, Alberta. Finally, TCPL acquired Curtis Palmer Hydroelectric
Company, L.P. in July 2001, which owns and operates two hydroelectric plants
near Corinth, New York which have a combined generating capacity of 60 MW. The
entire output from the Curtis Palmer plants are committed to a purchaser under a
long-term, fixed-price power purchase arrangement.

RECENT DEVELOPMENTS

On February 24, 2004, TransCanada announced an agreement to acquire Gas
Transmission Northwest Corporation ("GTNC") from National Energy & Gas
Transmission, Inc. ("NEGT") for approximately US$1.703 billion, including
US$500 million of assumed debt and subject to typical closing adjustments. The
acquisition of GTNC is subject to bankruptcy court approval, including
completion of a court sanctioned auction process, and to regulatory approval.
The agreement contemplates that final bankruptcy court approval of the sale will
be obtained within 75 days of signing the agreement.

GTNC is a natural gas pipeline company that owns and operates two pipeline
systems. The first of these is the Gas Transmission Northwest pipeline system,
formerly known as Pacific Gas Transmission, which extends more than
2,174 kilometres from a connection point on TCPL's BC System near Kingsgate,
British Columbia on the British Columbia -- Idaho border to a point near Malin,
Oregon on the Oregon -- California border. The second pipeline system, the North
Baja pipeline system, extends 128 kilometres from a point near Ehrenberg,
Arizona to a point near Ogilby, California on the California -- Baja California,
Mexico border. The natural gas transported on North Baja system comes primarily
from supplies in the southwestern United States for markets in Northern Baja
California, Mexico. The sale of the North Baja pipeline is subject to a right of
first refusal held by an unaffiliated company.

In a referendum held on March 9, 2004, the residents of Harpswell, Maine voted
against leasing a town-owned site for an LNG regasification facility which the
Fairwinds Partnership had been evaluating for development. The Fairwinds
Partnership subsequently announced that it has suspended any further work on the
project in Harpswell, Maine.

GAS TRANSMISSION

TCPL's transmission business principally includes the operation of the Canadian
Mainline, the Alberta System, the Foothills System, the BC System and TCPL's
other investments in natural gas pipelines located primarily in Canada and the
United States.

Canadian natural gas transmission services are provided under gas transportation
tariffs that provide for cost recovery including return of and return on capital
as approved by the applicable regulatory authorities. In some cases, such
tariffs are determined under agreements with customers and other interested
parties, subject to regulatory approval. The net income of the gas transmission
business is generated based on such tariffs. Under the current regulatory model,
net income is not affected by fluctuations in the commodity price of natural
gas, but such fluctuations influence both production levels and the natural gas
basins from which North American natural gas users elect to purchase natural gas
supplies.

The volume of natural gas shipments on the Canadian Mainline, the Alberta
System, the Foothills System and the BC System depends on the volume of natural
gas produced and sold both in and outside of Alberta, and on the construction
and availability of other pipeline capacity. The natural gas transported by TCPL
comes primarily from the Western Canada Sedimentary Basin ("WCSB"). The WCSB's
estimated remaining established reserves of natural gas are approximately 57
trillion cubic feet ("TCF") with a remaining reserve-to-production ratio of
approximately nine years at current levels of production. Incremental reserves
are continually being discovered, and generally maintain the
reserve-to-production ratio at close to nine years. Production of natural gas
from the WCSB has not increased since 2001. With the expansion of capacity on
TCPL's wholly and partially owned pipelines over the past decade and the
competition provided by other pipelines, combined with significant growth in
natural gas demand in Alberta, TCPL anticipates there will be excess pipeline
capacity out of the WCSB for the foreseeable future.

In addition to the information concerning the gas transmission segment of TCPL's
business set out herein, further information can be found in the MD&A under the
heading "Gas Transmission -- Wholly-Owned Pipelines -- Business Risks".

WHOLLY-OWNED PIPELINES

ALBERTA SYSTEM

The Alberta System, held by NOVA Gas Transmission Ltd. ("NGTL"), a subsidiary of
TCPL, is an Alberta-wide natural gas transmission system that collects and
transports natural gas for use in Alberta and for delivery to connecting
pipelines, such as the Canadian Mainline, the Foothills System and the BC
System, as well as to other unaffiliated pipelines, at various points on the
Alberta border for delivery to eastern Canada, British Columbia and the
United States. The Alberta System includes approximately 22,700 kilometres of
mainlines and laterals.

Capital expenditures, which are dependent in part upon requests for increased
transportation service by customers, were $53 million in 2003. TCPL anticipates
approximately $90 million of capital spending on the Alberta System in 2004.
These capital expenditures will be primarily related to capacity expansion.

The following table sets forth the annual volumes delivered off the Alberta

NOTES:

(1) Of the total volumes transported in 2003, 1.89 Tcf of natural gas was
    delivered to the Canadian Mainline, 674 billion cubic feet ("BCF") of
    natural gas was delivered to the BC System (including the BC portion of the
    Foothills System) and 777 Bcf of natural gas was delivered to the
    Saskatchewan portion of the Foothills System.

(2) Of the total volumes transported in 2002, 2.09 Tcf of natural gas was
    delivered to the Canadian Mainline, 773 Bcf of natural gas was delivered to
    the BC System (including the BC portion of the Foothills System) and
    779 Bcf of natural gas was delivered to the Saskatchewan portion of the
    Foothills System.

    ALBERTA SYSTEM CONTRACTED FIRM TRANSPORTATION SERVICES

As of Year End, the Alberta System was providing transportation for 182 shippers
pursuant to approximately 15,500 firm service transportation contracts.

As of Year End, the weighted average remaining term of firm transportation
contracts was approximately 2.4 years compared to a weighted average remaining
term of 3.0 years as of December 31, 2002. Currently, these contracts are
renewable by the customer providing notice to NGTL at least twelve months prior
to the expiry of the current contract term. The Alberta System has seen a
30 per cent decrease in firm contracted capacity since the 1998-1999 contract
year. Further information about the Alberta System can be found in the MD&A
under the headings "Gas Transmission -- Wholly-Owned Pipelines -- Financial
Review" and "Gas Transmission -- Wholly-Owned Pipelines -- Business Risks".

    REGULATION OF THE ALBERTA SYSTEM

The construction and operation of the Alberta System is regulated by the EUB
primarily under the provisions of the GAS UTILITIES ACT (Alberta) and the
PIPELINE ACT (Alberta). NGTL also requires the EUB's approval for rates, tolls
and charges, and the terms and conditions under which it provides its services.
Under the provisions of the PIPELINE ACT, the EUB oversees various matters,
including the economic, orderly and efficient development of the pipeline, the
operation and abandonment of the pipeline, and certain related pollution and
environmental conservation issues. In addition to requirements under the
PIPELINE ACT, the construction and operation of

                                                TRANSCANADA PIPELINES LIMITED  7

natural gas pipelines in Alberta are subject to certain provisions of, and
require certain approvals under, other provincial legislation such as the
ENVIRONMENTAL PROTECTION AND ENHANCEMENT ACT (Alberta).

Alberta System tolls are designed to generate sufficient revenues for NGTL to
recover operating expenses, depreciation, taxes and financing costs of the
Alberta System, including interest on debt and payments on securities
attributable to the Alberta System, together with a return on deemed common
equity.

In February 2003, NGTL negotiated the Alberta System 2003 Revenue Requirement
Settlement ("2003 SETTLEMENT") with certain shippers and other interested
parties. Under the Alberta System 2003 Settlement, approved by the EUB on
June 24, 2003, NGTL's 2003 revenue requirement was fixed at $1.277 billion,
subject to certain adjustments, including variances from previous agreements,
CO(2) management service costs, and annual foreign exchange amortization
amounts.

In March 2003, NGTL negotiated the 2003 Tariff Settlement with certain shippers
and interested parties. The 2003 Tariff Settlement, approved by the EUB on
June 24, 2003, established NGTL's 2003 rates, tolls and charges for services,
certain new services and new terms and conditions for certain existing services.

In July 2003, NGTL filed evidence in the EUB's generic cost of capital
proceeding ("GCOC"). NGTL is seeking a return of 11 per cent on a deemed common
equity of 40 per cent for the Alberta System. NGTL has been advised by the EUB
that it expects to adopt a standardized approach to determining return and
capital structure for utilities under its jurisdiction through the GCOC. NGTL
expects the EUB to issue its decision in the third quarter of 2004.

In September 2003, NGTL filed Phase 1 of its Alberta System 2004 General Rate
Application ("GRA-PHASE 1") with the EUB. As part of the GRA-Phase 1, NGTL
applied to increase the composite depreciation rate from 4.00 per cent to
4.13 per cent. NGTL filed Phase 2 of the GRA, dealing with rate design and
services, in November 2003 ("GRA-PHASE 2"). The EUB will consider the
GRA-Phase 1 and GRA-Phase 2 in hearings scheduled to commence on April 1, 2004
and June 1, 2004, respectively.

On December 16, 2003, the EUB approved interim rates effective January 1, 2004,
which will remain in place until final 2004 rates are determined.

    TOLLING METHODOLOGY FOR THE ALBERTA SYSTEM

The current tolling methodology and rate design for the Alberta System features
differentiated pricing for each gas receipt point on the Alberta System. The
receipt-point price is dependent on geographic location, the diameter of the
pipe through which the customer's natural gas travels, and the term of the
transportation contract.

CANADIAN MAINLINE

The Canadian Mainline consists of approximately 14,900 kilometres of pipeline
system transporting natural gas from the Alberta border east to various delivery
points in Canada and at the United States border.

Capital expenditures on the Canadian Mainline in 2003 were approximately
$48 million. These expenditures were primarily for maintenance capital and plant
retirement projects. TCPL anticipates approximately $120 million of capital
spending on the Canadian Mainline in 2004. The expected 2004 capital
expenditures primarily relate to capacity capital, maintenance capital and plant
retirement projects.

NOTE:

(1) 2002 domestic revenues were reduced as a result of transportation service
    credits related to two new services offered in that year. Total credits of
    $662 million were reported against 2002 domestic revenues. These services
    were discontinued in 2003.

    CANADIAN MAINLINE CONTRACTED FIRM TRANSPORTATION SERVICES

As of Year End, the Canadian Mainline was providing transportation for 127
shippers pursuant to 352 firm service transportation contracts. Approximately
51 per cent of the total daily transportation volume represented by these
contracts relates to contracts for delivery of natural gas at United States
border points.

As of Year End, the weighted average remaining term of firm transportation
contracts on the Canadian Mainline was approximately 3.2 years compared to a
weighted average remaining term of 3.7 years at December 31, 2002. These
contracts are renewable by the customer providing notice to TCPL at least six
months prior to the expiry of the current contract term. The Canadian Mainline
last operated at capacity with one year or longer firm service contracts during
the 1998-1999 contract year. Since then, the Canadian Mainline has seen a
36 per cent decrease in firm contracted deliveries and a 15 per cent decrease in
total deliveries originating at the Alberta border and in Saskatchewan. Further
information can be found in the MD&A under the headings "Gas
Transmission -- Wholly-Owned Pipelines -- Financial Review" and "Gas
Transmission -- Wholly-Owned Pipelines -- Business Risks".

    REGULATION OF THE CANADIAN MAINLINE

Under the terms of the NATIONAL ENERGY BOARD ACT (Canada), the NEB regulates the
construction, operation, tolls and tariffs of the Canadian Mainline. The NEB is
the authority under the CANADIAN ENVIRONMENTAL ASSESSMENT ACT responsible for
considering the environmental and social impacts of proposed pipeline projects.
The Canadian Mainline tolls are designed to generate sufficient revenues for
TCPL to recover operating expenses, depreciation, taxes and financing costs of
the Canadian Mainline, including interest on debt and payments on preferred
securities attributable to the Canadian Mainline, together with a return on
deemed common equity.

The tolls are composed of a demand charge component and a commodity charge
component. The demand charge is independent of the volumes shipped and is
designed to recover fixed costs, such as fixed operating expenses, financing
costs (including a return on deemed common equity), taxes and depreciation. The
commodity charge is designed to recover variable operating costs. These charges
are paid by shippers under transportation contracts with TCPL.

                                                TRANSCANADA PIPELINES LIMITED  9

In June 2002, the NEB denied TCPL's request to adopt an after-tax weighted
average cost of capital methodology for establishing investment return and an
after-tax weighted average cost of capital of 7.5 per cent, equivalent to a
12.5 per cent rate of return on deemed common equity of 40 per cent ("FAIR
RETURN DECISION"). The NEB instead affirmed a formula established in 1995 for
setting return on common equity. Under this formula, the rate of return on
common equity for the Canadian Mainline was 9.61 per cent in 2001,
9.53 per cent in 2002 and 9.79 per cent in 2003. The NEB increased deemed common
equity to 33 per cent from the previously approved level of 30 per cent. In
September 2002, TCPL filed a request for a review and variance of the Fair
Return Decision which was denied by the NEB in February 2003. TCPL maintains
that the Fair Return Decision issued in June 2002 does not recognize the
long-term business risks of the Canadian Mainline and therefore, initiated an
appeal of the NEB's decision not to review and vary the Fair Return Decision, to
the Federal Court of Appeal. In May 2003, TCPL was granted leave to appeal. The
appeal hearing was heard the week of February 16, 2004 and the Federal Court of
Appeal's decision is expected to be rendered later in 2004.

In September 2002, TCPL filed an application with the NEB to approve new tolls
on the Canadian Mainline to be effective January 1, 2003 and the related public
hearings began in February 2003. In July 2003, the NEB issued its decision on
this matter which approved all key components of the application including an
increase in the composite depreciation rate from 2.89 per cent to
3.42 per cent, introduction of a new tolling zone in southwestern Ontario, an
increase to the Interruptible Transportation bid floor price and continuation of
the Fuel Gas Incentive Program. The rates approved in this decision are still
considered interim pending the disposition of TCPL's appeal to the Federal Court
of Appeal regarding the Fair Return Decision.

On December 18, 2003, the NEB approved interim rates effective January 1, 2004,
which should remain in place until final 2004 tolls are determined.

On January 26, 2004, TCPL filed an application with the NEB to determine tolls
applicable to the Canadian Mainline, effective January 1, 2004. In this
application, TCPL has requested an 11 per cent return on deemed common equity of
40 per cent.

FOOTHILLS SYSTEM

The Foothills System, which is regulated by the NEB and the Northern Pipeline
Agency of Canada, is a 1,040 kilometre natural gas pipeline that transports
western Canadian natural gas from central Alberta to connecting pipelines for
transportation to markets in the U.S. Midwest, Pacific Northwest, California and
Nevada and is owned by TCPL. TCPL merged Foothills' operations with its own in
February 2004. TCPL previously held a 50 per cent interest in Foothills and in
August 2003, acquired the remaining interest.

The Alaska Highway Pipeline Project, which would bring Prudhoe Bay natural gas
from Alaska to markets in Canada and the United States, involves pipeline
construction in Canada and Alaska. Foothills holds the certificates to build the
Canadian portion of the Alaska highway pipeline project and subsidiaries of
Foothills and TCPL hold certificates to build the Alaskan part of this project.

TCPL anticipates that it will spend approximately $7 million on the Foothills
System in 2004, which expenditures will primarily be for maintenance capital.

BC SYSTEM

The BC System consists of approximately 200 kilometres of pipeline that carries
natural gas from a connecting point with the Alberta System through the
southeastern corner of British Columbia to connect with the GTNC pipeline system
at the Canada-United States border near Kingsgate, British Columbia. The GTNC
pipeline system connects to California and the northwestern United States.
Further information can be found about the GTNC pipeline system under the
heading "General Development of the Business -- Recent Developments", above.

In 2003, capital expenditures on the BC System were approximately $2 million,
primarily for maintenance capital. TCPL anticipates approximately $2 million of
capital spending on the BC System in 2004, primarily for maintenance capital.

10  TRANSCANADA PIPELINES LIMITED

The BC System is regulated by the NEB on a complaint basis and the tolls are
based on a cost-of-service methodology. In December 2003, the NEB adopted
interim rates and charges for 2004 pending the resolution of certain issues with
shippers on the BC System.

OTHER GAS TRANSMISSION

TCPL actively pursues natural gas pipeline and pipeline-related development,
acquisition and operation opportunities in Canada and the United States, where
these opportunities are driven by strong customer demand.

    GREAT LAKES

TCPL holds a 50 per cent interest in Great Lakes which operates a
3,387 kilometre pipeline system. This system transports Canadian natural gas
from its interconnection with the Canadian Mainline at Emerson, Manitoba to
markets in central Canada at St. Clair, Ontario and serves markets in the
eastern and midwestern United States. Great Lakes' rates are based on a five
year settlement agreement which was approved by the U.S. Federal Energy
Regulatory Commission ("FERC") in 2001 and is effective until
October 31, 2005.

    TC PIPELINES, L.P.

TC PipeLines, L.P., a U.S. publicly-held limited partnership, was formed to
acquire, own and participate in the management of U.S. based pipeline assets. In
May 1999, TCPL's 30 per cent general partner interest in Northern Border was
conveyed to TC PipeLines, L.P. in exchange for cash and a 33.4 per cent interest
in TC PipeLines, L.P., 31.4 per cent of which is comprised of common units and
subordinated units, and two per cent of which is a general partnership interest.
TC PipeLines, L.P. also issued common units to the public. Northern Border
operates a 2,010 kilometre natural gas pipeline system which connects with the
Foothills System in Saskatchewan and serves the midwestern United States,
terminating at North Hayden, Indiana. In October 2001, Northern Border completed
a 55 kilometre pipeline extension and installed additional compression that
provides 545 MMcf/d of incremental transportation capacity to North Hayden,
Indiana and expanded Northern Border's delivery capability into the Chicago area
by approximately 30 per cent.

On September 1, 2000, TC PipeLines, L.P. acquired a 49 per cent general partner
interest in Tuscarora from TCPL, and TCPL, through a subsidiary, retains a one
per cent general partner interest in Tuscarora. Tuscarora is a 386 kilometre
natural gas pipeline system which has been in operation since December 1995.
This system transports natural gas from Malin, Oregon to Wadsworth, Nevada and
delivers to points in northeastern California. The Hungry Valley lateral
extension, Tuscarora's second city-gate connection into Reno, Nevada, was
completed in January 2001. On December 1, 2002, Tuscarora completed construction
and placed into service an expansion of its pipeline system, consisting of two
compressor stations and a 17 kilometre pipeline extension from the previous
terminus near Reno, Nevada to Wadsworth, Nevada. The expansion serves growing
power generation and residential requirements in northern Nevada. Tuscarora's
current contracted capacity is approximately 180 MMcf/d. In December 2003,
Tuscarora received management approval for an expansion project which will
provide for approximately 57 MMcf/d of incremental capacity on its system. The
capital cost for this expansion project is estimated to be US$16.6 million and
the expansion is scheduled to commence service in November 2005.

A subsidiary of TCPL acts as the general partner of TC PipeLines, L.P.

    IROQUOIS

Iroquois connects with the Canadian Mainline near Waddington, New York and
delivers natural gas to customers in the northeastern United States ("IROQUOIS
SYSTEM"). TCPL's aggregate interest in the Iroquois System, through two
subsidiaries, is 41 per cent.

Iroquois' Eastchester extension and expansion was completed and the facilities
were put into service in February 2004. This expansion extends the Iroquois
System from Long Island into New York City, adding 59 kilometres to the Iroquois
System and will provide an additional 230 MMcf/d of new service into this
market. The Iroquois System is now 663 kilometres in length.

In October 2003, FERC approved Iroquois' rate settlement ("IROQUOIS
SETTLEMENT"), which was filed in August 2003. The Iroquois Settlement is
effective from January 1, 2004 until December 31, 2007, during which period
Iroquois will reduce rates by approximately 13 per cent. Iroquois filed a
separate rate application with FERC in January 2004 to establish rates for the
Eastchester expansion. FERC has issued an order accepting Iroquois' application
and the approved rates will become effective July 1, 2004, subject to refund and
conditions.

    TRANS QUEBEC & MARITIMES

TCPL holds a 50 per cent interest in the 572 kilometre TQM System which connects
with the Canadian Mainline. TQM serves markets in Quebec and connects with the
Portland system. In January 2003, TCPL began performing the majority of
operating and administrative functions of TQM pursuant to a services agreement.
The TQM System is regulated by the NEB.

    PORTLAND

In September 2003, TCPL purchased an additional 10.1 per cent ownership interest
in Portland for approximately US$19 million. In December 2003, TCPL purchased a
further 18.3 per cent interest for approximately US$32 million. As a result of
these two transactions, TCPL currently holds a 61.7 per cent controlling
interest in Portland.

Portland is a 471 kilometre interstate pipeline that interconnects with the
pipeline system of TQM at the United States-Canada border near East Hereford,
Quebec, and with the Tennessee Gas Pipeline in Haverhill and Dracut,
Massachusetts. The southern sections of Portland's system, consisting of
163 kilometres of pipeline, are part of the joint facilities shared with the
Maritimes and Northeast Pipeline. Portland holds a one-third ownership interest
in the joint facilities.

Portland and customer representatives reached an agreement on new tolls and
Portland submitted an uncontested agreement to FERC in October 2002, which was
approved in its entirety in January 2003. The settlement agreement is effective
from April 1, 2002 until April 1, 2008.

    NORTHERN DEVELOPMENT

In 2003, TCPL continued to pursue pipeline opportunities to move both Mackenzie
Delta and Alaska North Slope natural gas to markets throughout North America.
TCPL worked with key stakeholders in the interest of participating in any
potential pipeline project.

TCPL, the Mackenzie Producers and the APG reached funding and participation
agreements in June 2003 that enable the APG to become a full participant in the
largest component of the proposed Mackenzie Gas Pipeline Project which involves
a natural gas pipeline system in the Mackenzie Valley that would move Mackenzie
Delta natural gas through a natural gas pipeline being constructed from Inuvik,
Northwest Territories to the northern border of Alberta, where it would then
connect with the Alberta System. TCPL has agreed to finance the APG for its
one-third share of project definition costs. This share is currently estimated
to be $90 million over three years. This loan will be repaid from the APG's
share of future pipeline revenues if the project proceeds. In 2003, TCPL funded
$34 million of this loan. Under the terms of the agreement, TCPL gains an
immediate opportunity to acquire up to five per cent equity ownership of the
pipeline at the time of construction. In addition, TCPL also gains certain
rights of first refusal if any of the Mackenzie Producers choose to sell their

in all expansion opportunities once the APG reaches a one-third share, with the
Mackenzie Producers and the APG sharing the balance.

TCPL continued to work with other Alaska Highway pipeline stakeholders in 2003
to advance the project. Resolution of Foothills' Special Charge was reached with
Foothills shippers and the Canadian Association of Petroleum Producers, and
subsequently approved by the NEB in March 2003. The resolution waives Foothills'
obligation to repay all past and future Special Charge collections when the
Alaskan gas starts flowing on the Foothills System. In October 2003, the
Government of Canada, reaffirmed its preference to utilize the framework
provided in the NORTHERN PIPELINE ACT (Canada) which granted Foothills the
certificates to transport Alaskan gas across Canada.

In January 2004, Foothills and the Kaska First Nation signed an Agreement in
Principle that provides the framework for a future participation agreement. The
Agreement in Principle marks the completion of the second stage of negotiations
that is expected to lead to a participation agreement for the Alaska Highway
Pipeline Project.

    LIQUEFIED NATURAL GAS

In September 2003, TCPL and ConocoPhillips announced the Fairwinds Partnership
to jointly evaluate a site in Harpswell, Maine for the development of an LNG
regasification facility. Approval must first be obtained for the Fairwinds
Partnership to lease a town-owned site for the LNG regasification facility and
the residents of the Town of Harpswell are expected to vote on this matter at a
referendum which is to be held in March 2004.

    VENTURES LP

TransCanada Pipeline Ventures Limited Partnership ("VENTURES LP"), which is a
subsidiary of TCPL, owns a 121 kilometre pipeline and related facilities, which
supply natural gas to the oil sands region of northern Alberta, and a
27 kilometre pipeline which supplies natural gas to a petrochemical complex at
Joffre, Alberta.

    CROSSALTA

TCPL holds a 60 per cent interest in Crossfield Storage Joint Venture which
controls an underground gas storage facility near Crossfield, Alberta. The
facility is commercially operated on behalf of the joint venture by CrossAlta
Gas Storage & Services Ltd., in which TCPL also holds a 60 per cent interest.

    TRANSGAS

TCPL holds a 46.5 per cent interest in TransGas de Occidente S.A., a Colombian
joint venture project which operates a 344 kilometre natural gas pipeline,
between the cities of Mariquita and Cali, Colombia.

REGULATION OF NORTH AMERICAN PIPELINES

Under the NATIONAL ENERGY BOARD ACT (Canada), the NEB regulates the construction
and operation of interprovincial pipelines and the Canadian portion of
international pipelines as well as the traffic, tolls and tariffs applicable to
those pipelines. The NEB also approves the import and export of natural gas.

Pipelines located within provincial boundaries are regulated by the applicable
provincial regulatory body.

The construction and operations of the Alberta System, Ventures LP's northern
Alberta oil sands pipeline and Joffre pipeline are regulated by the EUB.

With respect to TCPL's United States pipeline investments, the NATURAL GAS ACT
OF 1938 ("NGA") establishes the framework for regulation of interstate natural
gas transportation, facilities construction and terms and conditions of service.
FERC is charged with implementing the NGA's requirements. The terms and
conditions of service under which TCPL transports natural gas on the Great
Lakes' system are subject to NGA authorizations issued by FERC. Interconnected
natural gas pipelines and other United States interstate pipeline projects in
which TCPL has investments are subject to FERC and NGA regulation, as well as
certain state regulatory requirements.

                                               TRANSCANADA PIPELINES LIMITED  13

Further information about the regulation of the Canadian Mainline, Alberta
System and other pipeline systems, can be found under the headings "Gas
Transmission -- Wholly-Owned Pipelines" and "Gas Transmission -- Other Gas
Transmission" above and in the MD&A under the heading "Gas
Transmission -- Canadian Regulatory Environment".

COMPETITION IN GAS TRANSMISSION

TCPL's wholly-owned pipelines are connected to and supplied by one of North
America's largest natural gas basins, the WCSB. However, the WCSB is maturing
and it will be a challenge for producers to increase production in this basin.
Other pipeline systems connected to the WCSB, including some of TCPL's
interconnected pipelines, have expanded in the last few years. These expansions
have provided shippers with additional flexibility and competitive choices when
moving WCSB supplies to market. The WCSB gas supply is not expected to increase.

The Alberta System is the primary transporter of natural gas within the province
of Alberta and to provincial boundary points. However, there are a number of
alternative pipelines which offer price advantages and which compete with the
Alberta System. In anticipation of and in response to these developments, the
Alberta System's current tolling methodology was designed to enhance NGTL's
ability to provide competitive pricing and service flexibility and to provide
TCPL with the ability to respond to potential future bypass pipelines.

The Canadian Mainline is now one of five natural gas pipelines providing
transportation service from the WCSB. Increased competition has led to the
non-renewal of some of the firm service contracts on the Alberta System and the
Canadian Mainline, and has led to decreased utilization on certain pipeline
segments.

Further information about business risks in Gas Transmission can be found under
the heading "Risk Factors -- Gas Transmission" below and in the MD&A under the
headings "Gas Transmission -- Wholly-Owned Pipelines -- Business Risks" and "Gas
Transmission -- Other Gas Transmission -- Business Risks".

RESEARCH AND DEVELOPMENT

In 2003, TCPL spent approximately $9.3 million on research and development
activities of which approximately $3.5 million related to research on pipeline
integrity management, approximately $2.8 million on other regulated pipeline
activities and approximately $3.0 million on non-regulated pipeline ventures.

POWER

The power segment of TCPL's business includes the construction, ownership,
operation and management of power plants and the marketing of electricity, and
provides electricity account services to energy and industrial customers. This
segment operates in Canada and the United States.

TCPL owns and operates:

    - cogeneration plants in Alberta at Carseland (80 MW), Redwater (40 MW),
      Bear Creek (80 MW) and MacKay River (165 MW);

    - a waste-heat fuelled power plant at the Cancarb facility in Medicine Hat,
      Alberta (27 MW);

    - the Curtis Palmer hydroelectric power facility near Corinth, New York
      (60 MW); and

    - the gas-fired, combined-cycle Ocean State Power plant in Burrillville,
      Rhode Island (560 MW).

TCPL has long-term power purchase arrangements in place for:

    - 100 per cent of the production of the Sundance A (560 MW) and
      50 per cent interest, through a partnership, of the production of Sundance
      B (353 MW of 706 MW) power facilities near Wabamun, Alberta.

TCPL operates the following facilities owned by Power LP:

    - five cogeneration power plants in Ontario and one wood-fired power plant
      in British Columbia (264 MW); and

14  TRANSCANADA PIPELINES LIMITED

    - one cogeneration power plant in the United States (64 MW).

TCPL owns, but does not operate:

    - the simple-cycle ManChief power plant near Brush, Colorado (300 MW);

    - a 31.6 per cent interest in the nuclear power generation facilities of
      Bruce Power in Ontario (1,472 MW of 4,660 MW total that is in operation
      and under commissioning); and

    - a 17 per cent interest in Huron Wind L.P. (2 MW of a total of 9 MW).

TCPL owns the following facilities which are under construction:

    - the 550 MW cogeneration Becancour plant, which is expected to be complete
      in late 2006; and

    - the 90 MW cogeneration Grandview plant, which is expected to be complete
      by the end of 2004.

While a significant portion of TCPL's western plant generation is sold under
long-term contract, in order to mitigate price risk, some power positions are
held for short-term transactions. The western power marketing group's primary
function is to manage those open positions in order to maximize the value of
TCPL's power assets.

TCPL has a power marketing office in Westborough, Massachusetts to manage the
Ocean State Power purchase agreements and market supply obligations, and to take
advantage of additional marketing opportunities in the New England and New York
markets. The office also markets the output of Power LP's Castleton power plant.

Output from the Curtis Palmer facilities is sold under a fixed-price, long-term
power purchase agreement to Niagara Mohawk Power Corporation for a term of more
than 25 years. In 2000, the Curtis Palmer facility was re-licensed by FERC to
operate for a period of 40 years.

The entire capacity of the ManChief power plant is sold under long-term tolling
contracts that expire in 2012. Operations and maintenance services for the
ManChief power plant will continue to be supplied by the current contracted
unaffiliated service provider.

Operations and maintenance services for the Bruce Power plants continue to be
supplied by the pre-acquisition management and staff of Bruce Power. Bruce Power
sells the output from the Bruce Power plants through a combination of
fixed-price contracts and spot market sales.

TCPL and OPG, through their limited partnership, Portlands Energy Centre L.P.,
continue to study the feasibility of developing a 550 MW combined-cycle natural
gas-fuelled cogeneration power plant on a former power generation site in the
Portlands area of the Toronto, Ontario downtown waterfront.

TCPL continues to investigate potential power investment opportunities
throughout North America.

TRANSCANADA POWER, L.P.

TCPL manages, operates and is the largest unit holder of Power LP, a
publicly-held limited partnership that owns seven power plants. TCPL holds
35.6 per cent of the units of Power LP.

Power LP owns combined-cycle power plants, fuelled by a combination of natural
gas and waste heat from adjacent TCPL compression facilities, in Nipigon,
Kapuskasing, North Bay and Tunis, Ontario. It also owns a natural gas
cogeneration plant at Castleton-on-Hudson, New York and wood-waste fuelled power
plants near Hearst, Ontario and at Williams Lake, British Columbia.

TCPL supplies the natural gas fuel for certain of Power LP's plants.

Power LP's seven plants have a total generating output of 328 MW. It is the
largest publicly traded power limited partnership in Canada with a market
capitalization of approximately $1.4 billion.

NOTES:

(1) Includes 100 per cent of volumes sold by, and the generation capacity of,
    Power LP (after eliminating intercompany transactions with TCPL).

(2) TCPL, directly or indirectly, acquires 560 MW from Sundance A and 353 MW
    from Sundance B through long-term power purchase arrangements, which
    represent 100 per cent of the Sundance A and 50 per cent of the Sundance B's
    power plant output, respectively.

(3) Includes 31.6 per cent of Bruce Power.

(4) Excludes MacKay River (165 MW), Becancour (550 MW), Grandview (90 MW) and
    Bruce A, Unit 3 (237 MW) which were not in commercial service at Year End.

REGULATION OF POWER

TCPL's investments in Ocean State Power, Curtis Palmer, ManChief, and TCPL's
United States electric power marketing activities are subject to the
jurisdiction of FERC under the U.S. FEDERAL POWER ACT, as well as the
jurisdiction of certain state regulatory authorities.

Deregulation of the power industry is proceeding at different stages throughout
most of the markets in which TCPL currently operates, which are primarily
Alberta, Ontario and the northeastern United States. In 2001, Alberta
deregulated its generation assets and opened the market for retailers and
wholesalers. In May 2002, the government of Ontario began the operation of a
competitive, bid-based wholesale market for electricity in Ontario, a process
that began with legislation first enacted under the ELECTRICITY ACT in 1998.
Later in 2002, after considerable volatility and rising prices under this
bid-based wholesale market, the government of Ontario put in place price caps at
the retail level, effectively shielding eligible customers from the wholesale
price volatility. In late 2003, after a change in government in Ontario, these
retail caps were adjusted upwards to be effective on April 1, 2004, to better
reflect the real cost of electricity. These caps do not directly affect the
wholesale market

16  TRANSCANADA PIPELINES LIMITED

in which TCPL is primarily focused through its interests in Ontario power
generation assets. More recently, however, the government of Ontario has
suggested it is considering further changes to the structure and operations of
the Ontario electricity market and the legislation that governs it. It is
possible that future legislative changes may have an impact on TCPL's Ontario
operations. In 1998 and 1999, respectively, the FERC began operations of
competitive, bid-based wholesale power markets in New England and New York. In
2003, New England adopted a reformed wholesale market, in line with the FERC's
long-term vision for a Standard Market Design.

COMPETITION IN POWER

TCPL's power business has operated and continues to operate in highly
competitive markets that are driven mainly by price. However, the majority of
TCPL's power generation business, excluding Bruce Power, is underpinned by
long-term or medium-term, fixed-price contracts that are unaffected by
short-term price changes in the marketplace.

Further information about business risks in TCPL's Power business can be found
in the MD&A under the headings "Risk Factors -- Power" and "Power -- Business
Risks".

OTHER INTERESTS

CANCARB LIMITED

TCPL owns Cancarb Limited, a thermal carbon black manufacturing facility located
in Medicine Hat, Alberta.

TRANSCANADA TURBINES

TCPL owns a 50 per cent interest in TransCanada Turbines Ltd., a repair and
overhaul business for aero-derivative industrial gas turbines. This business
operates primarily out of facilities in Calgary, Alberta, with offices in
Bakersfield, California; East Windsor, Connecticut; and Liverpool, England.

TRANSCANADA CALIBRATIONS

TCPL owns an 80 per cent interest in TransCanada Calibrations Ltd., a gas meter
calibration business certified by Measurement Canada, located at Ile des Chenes,
Manitoba.

DISCONTINUED OPERATIONS

Between 1999 and 2002, TCPL continued to focus on natural gas transmission and
power generation. During that time, TCPL sold substantially all of its assets in
international, midstream, and oil and gas marketing businesses that were
identified for disposition. For further information about Discontinued
Operations please refer to Note 18 of TCPL's 2003 Audited Consolidated Financial
Statements.

GAS MARKETING AND TRADING

TCPL's Board of Directors ("BOARD") approved a plan in July 2001 to dispose of
TCPL's gas marketing business and TCPL's exit from gas marketing was
substantially completed by December 31, 2001. TCPL remains contingently liable
for certain residual obligations.

INTERNATIONAL

In December 1999, TCPL announced its intention to exit from all of its
international operations and during 2000 and 2001, sold the majority of its
international businesses and assets. TCPL's remaining material international
investments are described in the following section and will be accounted for as
part of continuing operations as of Year End due to the length of time it has
taken TCPL to dispose of these assets:

TCPL holds:

    - a 30 per cent interest in Gasoducto del Pacifico ("GAS PACIFICO"), a
      540 kilometre natural gas pipeline from Argentina to Concepcion, Chile;

                                               TRANSCANADA PIPELINES LIMITED  17

    - a 30 per cent interest in INNERGY Holdings S.A., an industrial natural gas
      transportation and marketing company operating in the area of Concepcion,
      Chile, which transports gas on the Gas Pacifico system; and

    - an indirect ten per cent net interest in PT Paiton Energy Company, which
      owns a power project consisting of two 615-megawatt coal-fired power units
      located in Indonesia.

REGULATION IN INTERNATIONAL

The majority of countries in which TCPL continues to have business interests
have various government entities in charge of drafting and implementing the
policies and regulations with respect to exploration, production,
transportation, refining, processing and distribution of hydrocarbons, as well
as all other activities related to the energy sector.

COMPETITION IN INTERNATIONAL

TCPL's international businesses are conducted in a highly competitive
environment, comprised of major energy companies and consortia with years of
international experience and established relationships. Projects were generally
awarded by way of international tender.

TCPL's international investments are subject to a number of risks unique to
international business. Such risks are mitigated by insurance policies,
participation of local and foreign partners, prudent commercial structuring and
other measures.

For additional information about international business risks, please see "Risk
Factors -- International", below.

MIDSTREAM

In 2000 and 2001, TCPL sold substantially all of its portfolio of natural gas
gathering, processing, straddle plant and extraction assets in western Canada.

In January of 2003, TCPL sold its last remaining midstream asset, the Harmattan
gas plant located near Didsbury, Alberta, thus concluding TCPL's involvement in
midstream activities.

                         HEALTH, SAFETY AND ENVIRONMENT

TCPL is committed to providing a safe and healthy environment for its employees
and the public, and to the protection of the environment. Health, safety and
environment ("HS&E") is a priority in all of TCPL's operations. The HS&E
Committee of the Board monitors compliance with the TCPL HS&E corporate policy
through regular reporting by TCPL's department of Community, Safety &
Environment. TCPL's senior executives are also committed to ensuring TCPL is in
compliance with its policies and is an industry leader. Senior executives are
regularly advised of all important operational issues and initiatives relating
to HS&E.

TCPL has an HS&E management system modeled after ISO 14001 elements to
facilitate the focus of resources on the areas of greatest risk to the
organization's business activities relating to HS&E. It highlights opportunities
for improvement, enables TCPL to work towards defined HS&E expectations and
objectives, and provides a competitive business advantage. HS&E audits,
management system assessments and planned inspections are used to assess both
the effectiveness of implementation of HS&E programs, processes and procedures,
and TCPL's compliance with regulatory requirements.

TCPL employs full-time staff dedicated to HS&E matters, and incorporates HS&E
policies and principles into the planning, development, construction and
operation of all its projects. Environmental protection requirements have not
had a material impact on the capital expenditures of TCPL to date; however there
can be no assurance that such requirements will not have a material impact on
TCPL's financial or operating results in future years. Such requirements can be
dependent on a variety of factors including the regulatory environment in which
TCPL operates.

18  TRANSCANADA PIPELINES LIMITED

CLIMATE CHANGE

Climate change is a strategic issue for TCPL, particularly in light of the
Canadian government's ratification of the Kyoto Protocol in December 2002. TCPL
has had a comprehensive climate change strategy in place since 1999, which
includes five key areas of activity:

    - Participation in policy forums;

    - Direct emissions reduction programs;

    - Long-term technology development;

    - Emissions offset analysis; and

    - Pursuit of business opportunities.

Activities in each of these areas occurred in 2003 and will continue in 2004.

TCPL received a fifth consecutive gold level reporting status for its 2003
Voluntary Challenge and Registry ("VCR") report. To achieve gold level status,
VCR reports are rated in several categories. Only 12 per cent of the submissions
to the registry have received gold level reporting recognition.

The Kyoto Protocol, ratified by the Canadian Federal Government in
December 2002, requires Canada to reduce its greenhouse gas emissions
significantly. The Canadian government is currently developing the policies
relating to how it intends to meet these reduction targets, and until it is
completed, TCPL cannot predict the degree to which it will be affected.

                        PATENTS, LICENCES AND TRADEMARKS

TCPL is the beneficial owner and, in some cases, the licensee of a number of
trademarks, patents and licenses. While these trademarks, patents and licenses
constitute valuable assets, TCPL does not regard any single trademark, patent or
license as being material to its operations as a whole.

                               LEGAL PROCEEDINGS

TCPL is subject to various legal proceedings and actions arising in the normal
course of business. For further information, refer to Note 17 of TCPL's 2003
Audited Consolidated Financial Statements.

                                  RISK FACTORS

A number of factors, including but not limited to those discussed in this
section, could cause actual results or events to differ materially from current
expectations.

TCPL's businesses are highly complex and are dispersed over tens of thousands of
square kilometres, often in remote locations. Pipeline and power facilities are
subject to operational risks, including mechanical failure, physical
degradation, operator error, manufacturer defects, labour disputes, terrorism,
failure of supply, catastrophic events and natural disasters. The occurrence or
continuation of such events could increase TCPL's costs and reduce its ability
to transport natural gas or generate power.

GAS TRANSMISSION

The Canadian Mainline, the Alberta System, the BC System and the Foothills
System transport natural gas from the WCSB. Continuing use of these systems is
dependent on a number of factors including the level of exploration and
development within the basin, the price of and demand for natural gas, the
ability of natural gas producers to deliver natural gas to the various pipeline
systems, the development of northern natural gas reserves, and the regulatory
environment for producers, transporters and consumers of natural gas.

Further information about competition risks in TCPL's natural gas transmission
business can be found under the heading "Business of TCPL -- Gas
Transmission -- Competition in Transmission" above and in the MD&A under the
headings "Gas Transmission -- Wholly-Owned Pipelines -- Business Risks" and
"Other Gas Transmission -- Business Risks".

                                               TRANSCANADA PIPELINES LIMITED  19

POWER

TCPL's power business and investments rely on feed stocks of natural gas,
biomass, water, coal and uranium. Failure to obtain adequate supplies of feed
stocks could affect TCPL's ability to generate electricity and fulfill its
supply obligations, and changes in prices of feed stocks could affect TCPL's
financial results. Although TCPL takes appropriate actions to mitigate most of
these risks, there can be no assurance that such actions will be adequate in all
circumstances.

TCPL does not operate the Bruce Power facility, the ManChief Power Plant or the
assets underlying the Sundance A or Sundance B power purchase arrangements.
Failure by the operators of these facilities to operate at the cost or in the
manner projected by TCPL could negatively affect TCPL's financial position.

TCPL does not own any of the power transmission lines over which its electricity
is transmitted and delivered. Any disruption in transmission could affect TCPL's
ability to supply electricity and could have an adverse impact on TCPL's
financial results.

Further information about competition risks in TCPL's power business can be
found under the headings "Business of TCPL -- Power -- Competition in Power"
above and in the MD&A under the heading "Power -- Business Risks".

INTERNATIONAL

TCPL's international investments are subject to a number of risks unique to
international business. These risks include exchange controls and fluctuation of
the local currency, political risk, community actions, changes in laws, price
control, the availability and quality of local labour skills, and labour unrest,
among others. Such risks are mitigated by insurance policies, participation of
local and foreign partners, prudent commercial structuring and other measures.

CORPORATE

TCPL carries on its businesses with numerous counterparties with a wide range of
creditworthiness. While processes are followed to address the creditworthiness
of certain of these counterparties, the failure of any counterparty to meet its
financial obligations could have an impact on TCPL's financial position. Such
failure could result from a number of factors beyond TCPL's control, including
(but not limited to) fluctuating commodity energy prices and interest rates,
changes in regulatory and economic environments, political instability and
legally reviewable activities.

TCPL operates in Canada and the United States and as a result, its financial
performance can be impacted by interest rates and foreign exchange rates. TCPL
has an active hedging program in place to address interest and foreign exchange
rate risks, but there can be no assurance that such hedging will be adequate to
address the risks.

TCPL's growth strategy is dependent upon acquiring or constructing facilities
and businesses that align with its current businesses. TCPL may incur costs in
the pursuit of acquisitions or development of power or natural gas transmission
assets that may not be completed. Failure by TCPL to consummate negotiated
acquisitions or new developments may result in contractual liabilities,
liquidated damages, additional costs and expenses which could affect financial
performance.

TCPL's growth is also dependent on access to capital markets in the
United States and Canada. Although significant credit facilities are currently
available, changing market conditions could result in a materially increased
cost of capital which would reduce TCPL's ability to pursue this growth.

Further information about TCPL's risk factors and risk management can be found
in the MD&A under the headings "Gas Transmission -- Wholly-Owned
Pipelines -- Business Risks", "Gas Transmission -- Other Gas
Transmission -- Business Risks", "Power -- Power-Business Risks" and "Liquidity
and Capital Resources -- Risk Management".

THREE YEAR SELECTED CONSOLIDATED FINANCIAL INFORMATION

Selected consolidated financial information for the years ended December 31,
2003, 2002 and 2001 is found in the MD&A under the heading "Selected Three Year
Consolidated Financial Data".

For a discussion on the factors affecting the comparability of the financial

DIVIDENDS

TCPL has no formal dividend policy. The Board annually reviews the financial
performance of TCPL and makes a determination of the appropriate level of
dividend to be declared in the following year.

Certain of TCPL's outstanding preferred shares contain restrictions requiring
that no dividends shall be declared or paid on common shares unless all
dividends payable on all shares ranking in priority to the common shares with
respect to payment of dividends have been declared and paid. In addition, there
are provisions in the various trust indentures and credit agreements to which
TCPL is a party, which restrict the payment of dividends on TCPL's common shares
in certain limited circumstances. At Year End, such provisions did not restrict
or alter TCPL's ability to declare or pay dividends.

                             MARKET FOR SECURITIES

TCPL's common shares are not listed as they are owned by TransCanada.

30  TRANSCANADA PIPELINES LIMITED

                         TRANSCANADA PIPELINES LIMITED
                                (THE "COMPANY")
                        CORPORATE GOVERNANCE GUIDELINES

A.  INTRODUCTION

    The board of directors of the Company and its management are committed to
    maintaining a high standard of corporate governance. This commitment
    includes adherence to the definition of corporate governance included in the
    1994 Toronto Stock Exchange Committee Report on Corporate Governance in
    Canada. The report defined corporate governance as meaning "the process and
    structure used to direct and manage the business and affairs of a company
    with the objective of enhancing shareholder value, which includes ensuring
    the financial viability of the business. The process and structure define
    the division of power and establish mechanisms for achieving accountability
    among shareholders, the board of directors and management. The direction and
    management of the business should take into account the impact on other
    stakeholders such as employees, customers, suppliers and communities".

    The Company is subject to a variety of corporate governance guidelines and
    requirements enacted by the Toronto Stock Exchange ("TSX"), the Canadian
    Securities Administrators ("CSA"), the New York Stock Exchange ("NYSE") and
    by the U.S. Securities and Exchange Commission ("SEC") under its rules and
    those mandated by the United States Sarbanes-Oxley Act of 2002 ("SOX"). The
    Company's corporate governance practices comply with the TSX Company Manual
    Corporate Governance Guidelines, governance rules of the NYSE applicable to
    foreign issuers and applicable requirements of the CSA and the SEC. The
    Company is also in substantial compliance with the CSA's Multilateral
    Instrument pertaining to audit committees that comes into force on
    March 30, 2004 and is applicable in 2005, and with the proposed corporate
    governance guidelines released for comment by the CSA on January 16, 2004
    and which are expected to be in force in 2005.

    The board has the responsibility for the overall stewardship of the Company,
    establishing the overall policies and standards for the Company in the
    operation of its businesses, and reviewing and approving the strategic
    plans. In addition, the board monitors and assesses overall performance and
    progress in meeting the Company's goals. Day to day management is the
    responsibility of the president and chief executive officer and senior
    management. To this end, the board has adopted the following guidelines to
    assist it in its corporate governance responsibilities.

B.  BOARD ORGANIZATION AND MEMBERSHIP

     1. CHAIR OF THE BOARD

       The board has currently determined to separate the positions of chairman
       of the board ("chair") and president and chief executive officer.

     2. NON-EXECUTIVE CHAIR

       The board has determined the chair of the Company shall serve in a
       non-executive capacity and shall be appointed by the board based on the
       recommendations of the Governance Committee, the committee of the board
       that has been delegated the responsibility to assess candidates for the
       position.

     3. LEAD DIRECTOR CONCEPT

       The board has adopted a policy that it have an independent director
       assume the responsibility of chairing scheduled meetings of outside
       directors or other responsibilities which the outside directors as a
       whole might designate from time to time. This will be the Chairman, if an
       outside director, or the chair of the Governance Committee, if not.

     4. BOARD SIZE

       Although the maximum number of directors permitted by TransCanada's
       Articles is 20, the board has determined that it is in the best interests
       of the Company to maintain a smaller board, in the range of

                                               TRANSCANADA PIPELINES LIMITED  31

       12 to 14. It is the board's belief that this range is currently
       sufficient to provide a diversity of expertise and opinions and allow
       effective committee organization, yet small enough for efficient meetings
       and decision-making.

       The Governance Committee is mandated to review the size of the board from
       time to time and recommend changes in size to the board when appropriate.
       The board has the ability to increase or decrease its size within limits
       defined by Articles of the Company.

     5. INSIDE AND OUTSIDE DIRECTORS

       The board believes that, as a matter of policy, there should be a
       majority of outside, unrelated and independent directors on the Company's
       board. To this end, the board has determined the number of officers or
       senior managers of the Company or its subsidiaries who may serve as
       directors at any one time shall be limited to a maximum of three.

       On matters of corporate governance, decisions will be made by the
       unrelated directors.

     6. "INDEPENDENCE" OF OUTSIDE DIRECTORS

       The Governance Committee undertakes an annual review to determine the
       existence of any relationships with the Company and to ensure the
       majority of directors are independent and unrelated to the Company, that
       all Committee members are independent and, where any relationships exist,
       the director is acting appropriately. The board annually determines the
       independent and unrelated status of each director, based on the
       Governance Committee's recommendations.

     7. PRIMARY EMPLOYMENT STATUS CHANGE

       The board has adopted a policy that requires any director whose primary
       employment status changes to notify the chair of the Governance
       Committee. A director in such circumstances is also deemed to have
       submitted his or her resignation from the Board. The Governance Committee
       shall in turn advise the board and provide recommendations on the
       member's continued service to the Company as a director. It is not
       intended that directors who retire or whose professional positions change
       should necessarily leave the board. The Governance Committee has the
       responsibility to assess the continued appropriateness of board
       membership under such circumstances.

     8. OFFICERS' BOARD MEMBERSHIP

       The board has determined that management members of the board shall not
       automatically stand for re-election after retirement or resignation from
       the Company. Any former officer of the Company serving on the board will
       be considered to be an inside director for purposes of corporate
       governance until such time as the applicable regulatory cooling off
       periods have been met and the outside directors determine that sufficient
       distance has been established from the officer's former executive duties
       to make the officer independent and unrelated to the Company.

     9. CRITERIA FOR BOARD MEMBERSHIP

       The Governance Committee reviews each year the general and specific
       criteria applicable to candidates to be considered for nomination to the
       board. The objective of this review is to maintain the composition of the
       board in a way that provides the best mix of skills and experience to
       guide the long-term strategy and ongoing business operations of the
       Company. This review takes into account the desirability of maintaining a
       reasonable diversity of backgrounds, skills and experience and personal
       characteristics such as age, gender, geographic residence, etc. among the
       directors along with the key common qualities required for effective
       board participation.

    10. SELECTION OF NEW DIRECTOR CANDIDATES

       The board is responsible for identifying suitable candidates to be
       recommended for election to the board by the shareholders. The Governance
       Committee has the responsibility for assessing potential nominees,
       screening their qualifications against the current skill and experience
       requirements of the board and making recommendations in this regard to
       the board. Directors are encouraged to identify potential candidates. The
       chair and president and chief executive officer are consulted and have
       input

32  TRANSCANADA PIPELINES LIMITED

       into the process. An invitation to stand as a nominee for election to the
       board will normally be made to a candidate by the board through the chair
       or the chair's delegate.

    11. NEW DIRECTOR ORIENTATION

       New directors are provided with an orientation and education program that
       includes written information about the duties and obligations of
       directors, the business and operations of the Company, documents from
       recent board meetings, and opportunities for meetings and discussion with
       senior management and other directors. The details of the orientation of
       each new director are tailored to that director's individual needs and
       areas of interest.

    12. FIXED TERMS FOR MEMBERSHIP ON THE BOARD

       The board does not believe it should establish a fixed term for
       membership on the board. While fixed terms could help ensure that there
       are fresh ideas and views available to the board, they have the
       disadvantage of losing the contribution of directors who have developed,
       over a period of time, increased insight into the Company and its
       operations and who, therefore, can be expected to provide an increasing
       contribution to the board as a whole.

    13. RETIREMENT AGE

       The board reviews the mandatory retirement age for directors from time to
       time. The board has currently determined that no person shall stand for
       election or re-election to the board if he or she attains the age of
       70 years on or before the date of the annual meeting called in relation
       to the election of directors.

    14. BOARD COMPENSATION

       The Governance Committee reviews the compensation of directors on an
       annual basis, taking into account such matters as time commitment,
       responsibility and compensation provided by comparative companies. The
       Committee makes recommendations to the board for consideration when it
       believes changes in compensation are warranted.

    15. SHARE OWNERSHIP BY DIRECTORS

       The board has determined that share ownership by directors is a positive
       step in helping directors align their interests with those of the
       shareholders. As the Company is a wholly owned subsidiary, of TransCanada
       Corporation, directors of the Company fulfill their share ownership
       requirement by owning shares in the parent, TransCanada Corporation. The
       board has adopted a policy guideline requiring directors to hold at least
       five times the value of their annual board retainer in common shares of
       TransCanada Corporation. Such holdings can be acquired over a period of
       five years and can take the form of actual share ownership or by holding
       the equivalent number of units in the Directors' Deferred Share Unit
       Plan.

C.  BOARD MEETINGS AND MATERIALS

     1. BOARD MEETING AGENDAS

       The chair and the president and chief executive officer establish the
       agenda for each board meeting.

       Any board member may suggest the inclusion of items on the agenda in
       advance of the meeting.

     2. MEETING MATERIALS DISTRIBUTED IN ADVANCE

       The board has determined that information and data that are important to
       the board's understanding of business issues be distributed to the board
       before each board meeting in sufficient time to ensure adequate
       opportunity exists for members' review. Management makes every attempt to
       make this material as concise as possible while still providing the
       desired information and focusing attention on critical issues to be
       considered by the board.

                                               TRANSCANADA PIPELINES LIMITED  33

     3. PRESENTATIONS

       As a general rule and when appropriate, presentation materials are sent
       to the board members in advance. Time is allocated at all board meetings
       to ensure that members' questions about the material can be answered.

     4. NON-DIRECTORS AT BOARD MEETINGS

       The board appreciates the value of the regular attendance at each board
       meeting of non-board members who are members of the Company's senior
       management.

       Attendance by senior management is determined by the president and chief
       executive officer with the concurrence of the chair.

       Management attendees are excused for any agenda items that are reserved
       for discussion among directors only.

     5. OUTSIDE DIRECTORS

       Directors who are not members of management meet at the end of each board
       meeting IN-CAMERA to discuss matters of interest independent of
       management.

D.  COMMITTEE ORGANIZATION AND MEETINGS

     1. BOARD COMMITTEES

       Each committee operates according to board-approved terms of reference.
       The committees are: (1) the Audit Committee; (2) the Governance
       Committee; (3) the Health, Safety and Environmental Committee; and
       (4) the Human Resources Committee.

     2. OUTSIDE, UNRELATED AND INDEPENDENT DIRECTORS

       The board believes that, as a matter of policy, each of the Committees
       should be composed entirely of independent and unrelated directors. The
       applicable requirements are addressed in the charters of each Committee.

     3. ASSIGNMENT AND ROTATION OF COMMITTEE MEMBERS

       The Governance Committee is responsible for recommending to the board the
       assignment of board members to various committees in consultation with
       the chair, the president and chief executive officer, and taking into
       account the wishes of individual board members.

       The board favours the periodic rotation of committee members and
       committee chairs. Such rotation, when recommended, will be made in a way
       that recognizes and balances the need for renewal of ideas, continuity,
       and the utilization of each director's particular expertise.

     4. COMMITTEE MEETINGS

       Committee chairs, in consultation with committee members, determine the
       frequency (consistent with the committee's terms of reference) and length
       of the meetings of the committees. Each committee reports to the board on
       the results of each meeting.

     5. COMMITTEE AGENDAS

       The chair of each committee, in consultation with the appropriate members
       of management, develops the committee's agendas. The chair of each
       committee ensures that the committee meets sufficiently often to
       discharge its delegated responsibilities.

E.  BOARD AND MANAGEMENT RESPONSIBILITIES

     1. BOARD RELATIONSHIP WITH MANAGEMENT

       The board supports and encourages the members of the Company's management
       in the performance of their duties and individual outside directors are
       encouraged to provide their counsel as needed.

34  TRANSCANADA PIPELINES LIMITED

       Management makes appropriate use of the board's skills before decisions
       are brought forward on key issues.

       Board members have complete access to management for relevant
       information. It is understood that board members will be prudent and be
       sure that this contact is not distracting to the business operation of
       the Company and that such contact, if in writing, be copied to the
       president and chief executive officer and the chair.

       The board encourages senior management to bring managers into board
       meetings from time to time to provide additional insight into the items
       being discussed. Such managers are expected to be those with growth
       potential who would benefit from their exposure to the board.

     2. CORPORATE STRATEGY

       The board believes that management is responsible for development of
       corporate strategy. It is the role of the board to review, question,
       validate and approve material changes in the strategies of the Company.

     3. LIMITS TO MANAGEMENT AUTHORITY

       The board establishes general authority guidelines that places limits on
       management's approval authority depending on the nature and size of the
       proposed transaction. These limits anticipate that some flexibility
       exists within approved budgets but otherwise must not be exceeded without
       prior board or appropriate committee approval.

     4. FORMAL EVALUATION OF THE PRESIDENT AND CHIEF EXECUTIVE OFFICER

       The Human Resources Committee conducts an annual review of the
       performance of the president and chief executive officer as measured
       against objectives established mutually in the prior year by the Human
       Resources Committee and the president and chief executive officer. The
       results of this annual review is communicated to the board's unrelated
       directors who then make an evaluation of the overall performance of the
       president and chief executive officer. This performance evaluation is
       communicated to the president and chief executive officer by the chair
       and the chair of the Human Resources Committee. The evaluation is used by
       the Human Resources Committee in its deliberations concerning the
       president and chief executive officer's annual compensation.

     5. SUCCESSION PLANNING AND MANAGEMENT DEVELOPMENT

       The board believes that succession planning and management development
       are key to the ongoing process that contributes substantially to the
       success of the Company. The president and chief executive officer
       provides a detailed annual report to the Human Resources Committee and a
       summary presentation to the board. The president and chief executive
       officer makes available to the Human Resources Committee his
       recommendation as to a successor in the event of the unexpected
       incapacity of the president and chief executive officer.

     6. PRINCIPAL RISKS

       The board is responsible for understanding the principal risks associated
       with the Company's business on an ongoing basis and it is the
       responsibility of management to assure that the board and its committees
       are kept well informed of these changing risks on a timely basis. It is
       important that the board understand and support the key risk decisions of
       management, which includes comprehending the appropriate balance between
       risks and rewards.

     7. INTERNAL CONTROLS AND MANAGEMENT INFORMATION SYSTEMS

       Fundamental to the discharge of the board's overall responsibilities is
       the existence of control systems that can in part ensure the effective
       discharge of these responsibilities. A balance has to be achieved between
       controls related to financial or other matters that give the board
       reasonable assurances that its responsibilities are discharged and, at
       the same time, avoiding the creation of an unnecessarily bureaucratic and
       costly system of control mechanisms. The confidence of the board in the
       ability and integrity of management is the paramount control mechanism.

                                               TRANSCANADA PIPELINES LIMITED  35

       The board has delegated to the Audit Committee the responsibility for the
       oversight of internal control procedures, to determine their
       effectiveness, and to monitor compliance with the Company's policies and
       codes of business ethics. The Audit Committee reports on these matters to
       the board.

       The Audit Committee requires management to implement and maintain
       appropriate systems of internal controls and meets with the Company's
       external auditors and its director of internal audit in executive
       sessions, and with management, on at least a quarterly basis to oversee
       the effectiveness of these systems.

     8. BOARD COMMUNICATIONS POLICY

       The board, or the appropriate committee thereof, reviews the content of
       the Company's major communications to shareholders and the investing
       public, including the quarterly and annual reports, and approves the
       proxy circular, the annual information form and any prospectuses that may
       be issued. The board believes that it is the function of management to
       speak for the Company in its communications with the investment
       community, the media, customers, suppliers, employees, governments and
       the general public. It is understood that the chair or other individual
       directors may from time to time be requested by management to assist with
       such communications. If communications from stakeholders are made to the
       chair or to other individual directors, management is informed and
       consulted to determine any appropriate response.

     9. OUTSIDE ADVISORS FOR INDIVIDUAL DIRECTORS

       Occasionally individual directors may need the services of an advisor or
       expert to assist on matters involving their responsibilities as board
       members. The board has determined that any director who wishes to engage
       an outside advisor at the expense of the Company may do so.

    10. ASSESSING THE PERFORMANCE OF THE BOARD, COMMITTEES AND INDIVIDUAL
        DIRECTORS

       The Governance Committee reports to the board annually on the evaluation
       of the performance of the board, each of its committees, and that of
       individual directors, based on the results of the directors' annual
       self-assessment questionnaire. In addition, formal interviews are
       undertaken annually by the chair, based on the results of the
       questionnaire and the Company's Individual Director Terms of Reference,
       with each member of the board and with each member of the executive
       leadership of the Company. The performance of the chair is annually
       evaluated against his terms of reference by the chair of the Governance
       Committee by means of formal interviews with each of the directors.

36  TRANSCANADA PIPELINES LIMITED

                                  SCHEDULE "C"
                     CODE OF BUSINESS ETHICS FOR EMPLOYEES

Personnel (includes all regular full, part-time and temporary employees) of
TransCanada and its subsidiaries and affiliates (the "Company") represent the
Company and are expected to act in a manner that will enhance the Company's
reputation for honesty, integrity and reliability. Our Code of Business Ethics
(the "COBE") is a statement on TransCanada's Business Practices and on how we do
business. The COBE applies to all personnel of TransCanada. When you have a
question about ethics or compliance, please refer to this policy.

The COBE will not give you an answer for every situation. If after reviewing it
you have questions, please seek additional guidance. If you have any doubt about
the right thing to do, ask your supervisor, manager, or Human Resources, Law or
Internal Audit Departments. You can also call our anonymous Ethics Help-Line at
1-888-920-2042.

The following Fundamental Principles of appropriate business conduct have been
established for all personnel working for or representing the Company. They are
applicable in all countries in which the Company operates, unless the laws of
those countries require a higher standard.

FUNDAMENTAL PRINCIPLES

A.  COMPLIANCE WITH LAWS

    The Company will conduct its business in compliance with all laws,
    regulations and other legal requirements applicable wherever the Company is
    carrying on business. No personnel shall directly or indirectly give, offer
    or agree to give or offer a loan, reward, advantage or benefit of any kind
    to a foreign public official or to any person for the benefit of a foreign
    public official in contravention of the CORRUPTION OF FOREIGN PUBLIC
    OFFICIALS ACT.

B.  CONFLICT OF INTEREST

    Personnel must ensure that no conflict exists between their personal
    interests and those of the Company. Personnel should also avoid placing
    themselves in positions that may be perceived as conflicts. Some examples of
    possible conflicts include:

    - FINANCIAL INTEREST -- Personnel and their families (families including
      spouse, children or spouse equivalent residing together) shall not own,
      control or direct a material financial interest (greater than 5%) in a
      supplier, contractor, competitor, or in any business enterprise which does
      or seeks to do business with the Company.

    - OUTSIDE BUSINESS ACTIVITIES -- Personnel shall not engage in any outside
      business or activity that is detrimental to the Company. Unless approved
      by the Company or your supervisor, personnel are expected to spend their
      full time and attention performing their jobs during normal business hours
      or as contracted.

    - OUTSIDE DIRECTORSHIPS -- Personnel shall not serve as a director, officer,
      partner, consultant or any other role in unaffiliated profit-making
      organizations if that activity is detrimental to the Company.
      Directorships in unaffiliated entities require the consent of the
      personnel's immediate supervisor or contract manager, and of the
      Governance Committee of the Board of Directors in the case of an ELT

25. OVERSIGHT FUNCTION

    While the Committee has the responsibilities and powers set forth in this
    Charter, it is not the duty of the Committee to plan or conduct audits or to
    determine that the Company's financial statements and disclosures are
    complete and accurate or are in accordance with generally accepted
    accounting principles and applicable rules and regulations. These are the
    responsibilities of management and the external auditors. The Committee, its
    Chair and any of its members who have accounting or related financial
    management experience or expertise, are members of the Board, appointed to
    the Committee to provide broad oversight of the financial disclosure,
    financial risk and control related activities of the Company, and are
    specifically not accountable nor responsible for the day to day operation of
    such activities. Although designation of a member or members as an "audit
    committee financial expert" is based on that individual's education and
    experience, which that individual will bring to bear in carrying out his or
    her duties on the Committee, designation as an "audit committee financial
    expert" does not impose on such person any duties, obligations or liability
    that are greater than the duties, obligations and liability imposed on such
    person as a member of the Committee and Board in the absence of such
    designation. Rather, the role of any audit committee financial expert, like
    the role of all Committee members, is to oversee the process and not to
    certify or guarantee the internal or external audit of the Company's
    financial information or public disclosure.

TCPL's net earnings for the year ended December 31, 2003 were $801 million
compared to $747 million in 2002 and $686 million in 2001. The increase of $54
million in 2003 compared to 2002 was due to higher net earnings from the Power
business and reduced net expenses in the Corporate segment, partially offset by
lower net earnings from the Gas Transmission business.

The increase in 2002 net earnings compared to 2001 was due to higher earnings
from the Gas Transmission business and reduced expenses in the Corporate
segment, partially offset by lower earnings from the Power segment. The Power
segment earnings in 2001 reflected the company's ability to capture significant
market opportunities created by high market prices and power price volatility.


                                      M-1


Net earnings from the Power business for the year ended December 31, 2003
included $73 million after tax from TCPL's investment in Bruce Power L.P. (Bruce
Power) which was acquired in February 2003 and a $19 million positive after-tax
earnings impact of a June 2003 settlement with a former counterparty which
defaulted in 2001 under power forward contracts. These increases were partially
offset by reduced operating and other income from the Power segment's Eastern
Operations, combined with higher general, administrative and support costs.

The decrease in net expenses of $11 million in the Corporate segment in 2003 was
primarily due to the positive impacts of a weaker U.S. dollar in 2003 compared
to 2002.

The reduction in net earnings of $31 million in the Gas Transmission business
for the year ended December 31, 2003 compared to 2002 was primarily due to the
decline in the Alberta System's 2003 net earnings, reflecting the one-year fixed
revenue requirement settlement reached between TCPL and its customers in
February 2003. Also, in June 2002, TCPL received the National Energy Board (NEB)
decision on its Fair Return application (Fair Return decision) to determine the
cost of capital to be included in the calculation of 2001 and 2002 tolls on the
Canadian Mainline. The results for the year ended December 31, 2002 included
after-tax income of $16 million, which represents the impact of the Fair Return
decision for 2001. The 2003 results for the Gas Transmission segment included
TCPL's $11 million share of a future income tax benefit adjustment recognized by
TransGas de Occidente S.A. (TransGas), while the 2002 results included TCPL's $7
million share of a favourable ruling for Great Lakes Gas Transmission Limited
Partnership (Great Lakes) related to Minnesota use tax paid in prior years.

Pursuant to a plan of arrangement, effective May 15, 2003, common shares of TCPL
were exchanged on a one-to-one basis for common shares of TransCanada
Corporation (TransCanada). As a result, TCPL became a wholly-owned subsidiary of
TransCanada. The Consolidated Financial Statements for the year ended December
31, 2003 include the accounts of TCPL, the consolidated accounts of all
subsidiaries, and TCPL's proportionate share of the accounts of the company's
joint venture investments.

TCPL OVERVIEW

TCPL is a leading North American energy company focused on natural gas
transmission and power generation. At December 31, 2003, the Gas Transmission
business accounted for approximately 86 per cent and Power approximately 14 per
cent of total operating assets of $19.7 billion. In 2003, the Gas Transmission
and Power businesses delivered net earnings of $622 million and $220 million,
respectively.

The Gas Transmission and Power businesses have similar characteristics and
business drivers. Infrastructure such as natural gas pipelines and power
generation are both driven by similar supply and demand fundamentals and these
markets are highly interdependent. Both businesses are capital intensive, employ
many similar technologies and operating practices, and require financial
strength and stability to support the capital required.

GAS TRANSMISSION The Gas Transmission segment includes the operation of four
wholly-owned regulated natural gas pipelines: the Canadian Mainline, the Alberta
System, the Foothills System and the BC System. TCPL's investments in Other Gas
Transmission principally include the partial ownership of one Canadian pipeline,
five United States pipelines and a 33.4 per cent interest in TC PipeLines, LP, a
publicly held U.S. limited partnership of which TCPL is the general partner. In
2003, the Gas Transmission business transported 66 per cent of the natural gas
produced in the Western Canada Sedimentary Basin (WCSB), 65 per cent of which
was exported to the U.S.

POWER TCPL's Power segment is primarily focused on power generation and includes
the construction, ownership, operation and management of electrical power
generation plants, with a total of 4,667 megawatts (MW) of generating capacity.
To generate electricity, the company uses various fuel sources such as natural
gas, waste heat, wood waste, coal, nuclear and hydro. TCPL also markets
electricity in order to optimize the asset value of the company's power
generation portfolio. Power's portfolio includes eight wholly-owned plants in
operation, a 31.6 per cent equity interest in the Bruce Power nuclear facility
and the power production from two power facilities in Alberta through power


                                      M-2


purchase arrangements (PPAs). In addition, there is one plant in the permitting
phase and another under construction. TCPL also holds a 35.6 per cent interest
in, and is the general partner of, TransCanada Power, L.P. (Power LP), a
publicly traded limited partnership that owns seven power plants.

TCPL'S STRATEGY

TCPL's goal is to be the most profitable, competitive and reliable provider of
natural gas transportation and power services in North America.

TCPL has five key strategies for achieving its goal:

     o    Sustain, grow and optimize the natural gas transmission business by
          connecting new WCSB supply, Northern gas and liquefied natural gas
          (LNG) to growing markets.

     o    Continue to work with regulators and customers to evolve the regulated
          business model to allow TCPL to earn competitive returns and compete
          in a North American market.

     o    Grow and optimize the power business.

     o    Continue to pursue an operationally excellent business model to ensure
          better, faster and cost effective delivery of natural gas and
          generation of power to customers.

     o    Maintain and effectively utilize the company's strong financial
          position to capitalize on growth opportunities when they arise.

GAS TRANSMISSION

OPPORTUNITIES North American natural gas demand is expected to grow to 85
billion cubic feet per day (Bcf/d) by 2015 from 70 Bcf/d in 2002, an increase of
21 per cent over this time period. While higher natural gas prices may result in
some demand destruction or fuel switching, TCPL expects that in the long term,
demand for natural gas will increase substantially. Flat to slightly increasing
production is expected in existing natural gas production basins as a result of
higher natural gas prices leading to increased drilling, offset by higher
decline rates and lower initial well production rates. Overall, supply from
traditional North American basins is expected to grow by 1 Bcf/d by 2015. These
expectations indicate that North America will require substantial incremental
volumes of natural gas from non-traditional sources to meet the increased
demand. This incremental natural gas supply is expected to come from frontier
regions such as Alaska and Canada's Mackenzie Delta, as well as from new LNG
opportunities. TCPL will continue to pursue growth of the current infrastructure
and develop new infrastructure linking new supply to growing markets.

Today, TCPL owns the largest pipeline network that links the WCSB with
significant growing markets in North America. In 2003, the Alberta System
gathered approximately 11 Bcf/d, representing 66 per cent of the natural gas
produced in the WCSB and 16 per cent of North American natural gas production.
Within Alberta, the company delivered approximately 1.6 Bcf/d. The Alberta
System connects to the Canadian Mainline, the BC System, the Foothills System
and other pipelines which collectively deliver natural gas to eastern Canada and
export natural gas to the U.S. Pacific Northwest, Midwest and Northeast.

STRATEGY One of TCPL's strategies is to sustain, grow and optimize its natural
gas transmission business by connecting new WCSB supply, Northern gas and LNG to
growing markets. The natural gas demand growth expected over the next several
years suggests that there will be ample opportunity to pursue this strategy. In
the short to medium term, growth is expected to come from debottlenecking
existing systems, increased ownership of partially-owned pipelines, acquisitions
of other pipeline systems and connecting new WCSB supply to market. In the long
term, TCPL is laying the groundwork for developing, building and operating new
infrastructure to bring Northern gas and LNG to growing markets.

TCPL's pursuit of a role in bringing Northern gas to market is also driven by
the fact that there is excess capacity on the company's main pipelines, the
Alberta System and the Canadian Mainline. If pipelines are built to deliver
natural gas from Prudhoe Bay and the Mackenzie Delta, and they connect to
existing pipeline systems, the economic viability of TCPL's pipelines will be
enhanced thereby benefiting TCPL's customers and shareholders.


                                      M-3


2003 BUSINESS DEVELOPMENTS In 2003, TCPL continued to deliver on its strategy of
sustaining, growing and optimizing its Gas Transmission business and took
several steps forward in working towards the goal of bringing Northern gas and
LNG to market.

In August 2003, the company acquired the remaining interests in Foothills Pipe
Lines Ltd. and its subsidiaries (Foothills) previously not held by TCPL. The
Foothills System, which extends more than 1,000 kilometres and carries over 30
per cent of Canadian natural gas exports to the U.S., complements TCPL's current
western Canadian facilities. The company also increased its ownership interest
in Portland Natural Gas Transmission System Partnership (Portland) in the
Northeast U.S. to 61.7 per cent from 33.3 per cent.

The Foothills acquisition has strengthened TCPL's position in the potential
Alaska Highway Pipeline Project. TCPL, through Foothills, holds certificates for
both the Alaskan and Canadian segments of the Alaska Highway Pipeline Project
and also holds significant right-of-way assets for the project in both Canada
and Alaska.

In June 2003, TCPL, the Mackenzie Delta gas producers and the Aboriginal
Pipeline Group (APG) reached a funding and participation agreement with respect
to the Mackenzie Gas Pipeline Project. TCPL has agreed to finance the APG for
its one-third share of project definition costs in exchange for several options,
including an ownership interest in the project, certain rights of first refusal
and the right to have the Mackenzie Delta gas flow into the Alberta System.

In September 2003, on the LNG front, TCPL and ConocoPhillips Company
(ConocoPhillips) announced the Fairwinds partnership to jointly evaluate a
liquefied natural gas regasification facility in Harpswell, Maine. If all
approvals are received, construction of this facility could begin in 2006 and be
in operation in 2009. TCPL also continues to pursue other LNG projects.

CHALLENGES While several positive developments occurred in 2003, there are
challenges to the company's ability to sustain, grow and optimize the Gas
Transmission business. The nature of the Gas Transmission segment's business
risks has changed over the past several years. Two major developments in the
pipeline sector in Canada have driven these risks: an increase in competition
and essentially flat supply of natural gas from the WCSB. TCPL faces competition
at both the supply end and the market end of the company's pipeline systems. On
the supply end, other pipelines are accessing an increasingly mature basin. On
the market end, there are other pipelines able to deliver natural gas to markets
that were historically served by TCPL.

TCPL's ability to grow through the acquisition of other pipeline systems is
dependent on the availability of quality pipeline assets for sale, the strength
of competitor bids and the company's ability to successfully execute its
acquisition strategy.

In the long term, TCPL's ability to play a significant role in delivering
Northern gas to market is dependent on gas producers' willingness and ability to
commit their resources to these projects. There are several factors impacting
the decision to proceed with these projects, including natural gas prices,
capital cost of the pipeline, regulatory approvals, and construction,
operational and financial risk.

With increased competition and essentially flat WCSB supply, TCPL expects there
will be little organic growth in its Canadian regulated pipelines, prior to
connecting Northern gas supplies. Since a key determinant of earnings is the
average investment base, the company also expects that in the absence of
increases in return on equity and deemed equity thickness, earnings from these
assets will decline. However, despite the potential for declining earnings, cash
flow generated from these mature assets is expected to remain strong.

CANADIAN REGULATORY DEVELOPMENTS While natural gas supply and demand
fundamentals support TCPL's strategy for growing and optimizing the Gas
Transmission business, its Canadian regulated pipelines continue to face the
challenges of competition, a maturing WCSB and overall low returns. These
challenges drive TCPL's perseverance to earn higher returns and compete in the
North American market.


                                      M-4


TCPL's Canadian regulated assets are approximately $14 billion representing 68
per cent of the company's total asset base at December 31, 2003. In the short to
medium term, the company's earnings from its wholly-owned regulated pipelines is
dependent not on the amount of natural gas that flows through the pipelines but
rather on the amount of capital that is invested in the pipelines, the allowed
rate of return and the deemed equity thickness. In the long term however, as
WCSB production declines and transportation tolls are impacted, shippers are
likely to be less willing to contract for natural gas transmission services.

The NEB regulates the Canadian Mainline, the Foothills System, the BC System as
well as the Trans Quebec & Maritimes System (TQM), in which the company holds a
50 per cent ownership interest. Earnings from these pipelines are based on the
average investment base and a rate of return on a deemed common equity ratio
that is determined by the regulator. In 2003, the Canadian Mainline average
investment base was $8.6 billion and earned the NEB formula of 9.79 per cent on
a deemed common equity ratio of 33 per cent. The NEB formula that determines the
rate of return is directly linked to the long-term Canada Bond yield. This leads
to a direct correlation between earnings on the Canadian Mainline and the level
of long-term interest rates in Canada and has resulted in the rate of return
declining substantially over the past decade.

The Alberta System is regulated by the Alberta Energy and Utilities Board (EUB).
In 2003, revenue for the Alberta System was based on a negotiated settlement
with customers on the pipeline. Negotiations with shippers on the Alberta System
were significantly influenced by the 2002 NEB decision on the Canadian
Mainline's return in 2001 and 2002. As a consequence, the earnings in the
Alberta System's revenue requirement were originally anticipated to be $40
million lower than in 2002. However, incentive earnings of approximately $16
million partially offset this decrease, resulting in a $24 million decline in
earnings in 2003 from 2002 for the Alberta System. In 2003, the EUB also
approved the Alberta System 2003 Tariff Application which introduced two new
services and certain modifications to rate design.

Over the past three years, TCPL has pursued in various regulatory proceedings
both the evolution of its regulated business model and fair returns. In 2001,
the company filed the Canadian Mainline 2001 and 2002 Fair Return Application
with the NEB. In the application, TCPL requested the NEB to adopt an after-tax
weighted average cost of capital approach to determining returns (instead of the
NEB formula tied to interest rates) and requested a higher return. In its June
2002 decision on this application, the NEB retained its formula for the return
calculation and increased the Canadian Mainline's deemed common equity ratio to
33 per cent from 30 per cent. The NEB denied TCPL's subsequent application to
review and vary the NEB's decision. TCPL then petitioned the Federal Court of
Appeal which granted leave to appeal. The appeal was heard in February 2004 and
TCPL awaits the judgment.

In July 2003, the NEB issued its decision on TCPL's 2003 Canadian Mainline Tolls
and Tariff Application. The NEB approved key components of the application
including an increase in the composite depreciation rate, introduction of a new
tolling zone, continuation of fuel incentives and an increase in the bid floor
price for interruptible service (IT). This decision addressed key issues such as
competition in the end markets of the Canadian Mainline, disincentives for
shippers to contract for firm service and the long-term supply risks faced by
the WCSB. Tolls for 2003 remain interim pending the outcome of the appeal to the
Federal Court of Appeal.

In 2003 and early 2004, the EUB held a Generic Cost of Capital (GCOC) proceeding
in Alberta. At the conclusion of this proceeding, the EUB will determine the
rate of return on equity for 2004 and the capital structure for each utility
under its jurisdiction, including the Alberta System. It also expects to adopt a
standardized approach to determining rate of return commencing in 2005.

TCPL filed Phase I of its Alberta System 2004 General Rate Application (GRA)
with the EUB in September 2003 and Phase II in November 2003. This is the first
GRA filed with the regulator since 1995. Between 1996 and 2003, the tolls and
services on the Alberta System were based on negotiated settlements with the
pipeline customers, which were approved by the EUB.

POWER

OPPORTUNITIES Power demand is expected to grow at the rate of two per cent per
year in North America. TCPL's Power segment has significant opportunities for
growth which will take place through quality acquisitions, niche development
opportunities and through the optimization of the company's power portfolio by
focusing on low-risk opportunities in known markets. Given current restrictions
on North American power transmission grids, there is also a need to build
efficient power plants that are in close proximity to demand areas.

STRATEGY Power will continue to focus on developing and acquiring low-cost, base
load generation or plants with strong contractual underpinnings in markets where
the company has or can acquire significant knowledge and experience. TCPL will
also grow the Power business by building plants that take advantage of efficient
cogeneration technology and serve niche markets.

TCPL's power plants are located in several different regulatory jurisdictions
and each one has unique rules and regulations. Power markets are regionalized
and in-depth knowledge of each market is important to the success of the
operation of these assets. TCPL has grown the Power business significantly in
Alberta, eastern Canada and the U.S. Northeast and has developed extensive
experience in these markets. TCPL will continue to capitalize on its market
knowledge and deregulation experience to optimize the asset value of its power
portfolio through marketing activities in these geographic areas. TCPL will
pursue operational excellence to be the most profitable and reliable provider of
power services in the markets the company serves.

2003 DEVELOPMENTS In 2003, TCPL acquired a 31.6 per cent interest in Bruce Power
and announced two new cogeneration plants in Canada. The Bruce Power investment
provides TCPL with low-cost, base load power generation in Ontario, one of the
largest markets in North America. Output from the new Quebec and New Brunswick
cogeneration facilities will be sold under long-term contracts to creditworthy
counterparties. These plants are examples of TCPL's ability to develop power
generation in new markets and capitalize on the company's expertise in
cogeneration technology.

CHALLENGES TCPL's main challenges in growing its Power business include the
availability of quality acquisition opportunities, and the company's ability to
capture those opportunities and find niche markets to develop new power plants.

Power generation is primarily a manufacturing business. TCPL uses various fuel
sources such as natural gas, waste heat, wood waste, coal, nuclear and hydro to
generate electricity. A key success factor in any manufacturing business is the
ability to operate at the lowest cost possible. There are several drivers of
costs in the power generation business such as construction, start-up, fuel and
operating costs which TCPL manages through its operational excellence model.
TCPL's ability to optimize its power assets is driven by factors such as
contractual profile, plant availability, reliability, fuel mix management and
portfolio/dispatch optimization.

The power markets in North America began deregulating in the mid-1990s and the
deregulation process continues to evolve in some markets. Evolving markets can
lead to short- to medium-term uncertainty around market structure, including how
power and fuel contracts are structured. This ultimately impacts earnings
volatility. TCPL has been successful in operating in both deregulated and
regulated markets.

TCPL - OUTLOOK

In 2004, TCPL will continue to execute its strategy to grow and optimize its Gas
Transmission and Power businesses by redeploying its strong discretionary cash
flow.

In the Gas Transmission business, the company will pursue growth through the
expansion of current systems to bring new supplies to market, acquisitions of
existing pipelines, increased ownership in partially-owned pipelines and
continued efforts to bring new sources of natural gas (including Northern gas


                                      M-6


and LNG) to growing markets. In 2004, the outcome of regulatory proceedings
could have a significant impact on the earnings of the Alberta System and
Canadian Mainline.

In the Power business, TCPL will focus on markets in which the company currently
operates and has extensive market knowledge and deregulation experience. The
company will pursue growth of a balanced portfolio of gas-fired and non
gas-fired power plants by building, acquiring and investing in competitive
facilities. TCPL will focus on low-cost, base-load generation or assets with
strong contractual underpinnings and strive to be one of the lowest-cost
providers of power services in North America. Power projects undertaken will
benefit from and support TCPL's strong balance sheet. In 2004, plant
availability and fluctuating power prices, especially for Bruce Power, could
have a significant impact on the earnings of the Power segment.

Financial flexibility is one of the most important requirements for growing the
company. Net earnings and cash flow, combined with a strong balance sheet,
continue to provide the financial flexibility for TCPL to make disciplined
investments in its core businesses of Gas Transmission and Power.

ACQUISITION OF GAS TRANSMISSION NORTHWEST

On February 24, 2004, TransCanada announced an agreement to acquire Gas
Transmission Northwest Corporation (GTN) from National Energy & Gas
Transmission, Inc. (NEGT) for approximately US$1.7 billion, including US$500
million of assumed debt and subject to typical closing adjustments.

GTN is a natural gas pipeline company that owns and operates two pipeline
systems - the Gas Transmission Northwest pipeline system, formerly known as
Pacific Gas Transmission, and the North Baja Pipeline system.

The Gas Transmission Northwest pipeline system consists of more than 2,174
kilometres of pipeline extending from a point near Kingsgate, British Columbia,
on the British Columbia-Idaho border, to a point near Malin, Oregon on the
Oregon-California border. The natural gas transported on this pipeline
originates primarily from supplies in Canada for customers located in the
Pacific Northwest, Nevada and California.

The North Baja pipeline is a 128 kilometre system. It extends from a point near
Ehrenberg, Arizona to a point near Ogilby, California on the California-Baja
California, Mexico border. The natural gas transported on this system comes
primarily from supplies in the southwestern United States for markets in
Northern Baja California, Mexico. The sale of the North Baja pipeline is subject
to a right of first refusal by another company.

NEGT voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy
Code in July 2003. As a result, the sale of GTN to TransCanada will be subject
to bankruptcy court approval, and will include a court-sanctioned auction
process in accordance with customary bidding procedures approved by the
bankruptcy court. Under a court-sanctioned auction, NEGT will seek offers that
are higher or otherwise better than that which has been negotiated with
TransCanada. As part of its agreement, TransCanada is granted certain
protections, subject to court approval, most notably a break fee and expense
reimbursement if another bid is accepted. TransCanada also retains the right to
amend its offer should NEGT receive an offer which is superior to its existing
agreement with TransCanada. The agreement contemplates that final bankruptcy
court approval of the sale will be obtained within 75 days after signing of the
agreement. The agreement also contemplates bankruptcy court approval of the NEGT
Plan of Reorganization. Approval of NEGT's Plan could occur at a date later than
the receipt of court approval of the sale. The sale is also subject to
anti-trust review.

TransCanada will finance the acquisition in a manner consistent with maintaining
its solid financial position and credit ratings. This could include use of
internally generated cash flow, draws on committed credit lines, issuance of
debt and/or equity under the Canadian and U.S. shelf prospectuses and/or the
sale of certain assets within the company's existing portfolio.

GAS TRANSMISSION

HIGHLIGHTS

EARNINGS Net earnings from Gas Transmission decreased $31 million to $622
million in 2003 compared to $653 million in 2002. This decrease is a result of
reduced earnings of $38 million from Wholly-Owned Pipelines partially offset by
increased earnings of $7 million from Other Gas Transmission.

ALBERTA SYSTEM In February 2003, a one-year Alberta System Revenue Requirement
Settlement (the 2003 Settlement) was reached for 2003 with Alberta System
customers. Earnings in 2003 were initially expected to decrease by approximately
$40 million relative to 2002 earnings of $214 million. However, incentive
earnings realized primarily from lower financing and operating costs partially
offset the expected reduction in earnings.

CANADIAN MAINLINE In July 2003, the NEB issued its decision on TCPL's 2003
Canadian Mainline Tolls and Tariff Application. In its decision, the NEB
approved all of the key components of the application including an increase in
the composite depreciation rate to 3.42 per cent from 2.89 per cent,
introduction of a new tolling zone in southwestern Ontario, an increase to the
IT bid floor price and the continuation of the Fuel Gas Incentive Program.
Earnings in 2003 reflect, along with incentive earnings from approved programs,
return on equity based on the NEB formula and 33 per cent deemed common equity.

FOOTHILLS SYSTEM In August 2003, TCPL acquired the remaining interests in
Foothills previously not held by the company. This acquisition has strengthened
TCPL's position in the potential Alaska Highway Pipeline Project and increased
the likelihood that such a project would connect with TCPL's existing
infrastructure.

OTHER GAS TRANSMISSION In 2003, TCPL increased its ownership interest in
Portland to 61.7 per cent from 33.3 per cent through two separate transactions.
This increase in ownership, in conjunction with the impact of Portland's 2003
rate settlement, resulted in increased net earnings to TCPL. TCPL's investment
in TransGas also generated higher net earnings in 2003. Net earnings from Other
Gas Transmission in 2003 were negatively impacted by U.S. dollar currency
movements, as the majority of earnings in this business are denominated in U.S.
dollars. Iroquois Gas Transmission System (Iroquois) placed its Eastchester
expansion facilities into service in February 2004.

(1)  The remaining ownership interests in Foothills previously not held by TCPL
     were acquired on August 15, 2003. Amounts in this table reflect TCPL's
     proportionate interest in Foothills' earnings prior to acquisition and 100
     per cent interest thereafter.

(2)  TCPL increased its ownership interest in Portland to 43.4 per cent from
     33.3 per cent in September 2003 and to 61.7 per cent from 43.4 per cent in
     December 2003. Amounts in this table reflect TCPL's proportionate earnings
     from Portland including a 33.3 per cent ownership interest from June 2001
     to September 2003, and a 21.4 per cent ownership interest prior to June
     2001.

In 2003, net earnings from the Gas Transmission business were $622 million,
compared to $653 million and $585 million in 2002 and 2001, respectively. The
decrease in 2003 compared to 2002 was mainly due to lower net earnings from
Wholly-Owned Pipelines, partially offset by higher net earnings from Other Gas
Transmission. The 2003 decrease in Wholly-Owned Pipelines' net earnings was
primarily due to a reduction in the Alberta System's net earnings reflecting the
2003 Settlement. Further, earnings on the Canadian Mainline were lower in 2003
compared to 2002 due to recognition in June 2002 of the 2001 earnings impact
resulting from the Fair Return decision. Higher 2003 net earnings from Other Gas
Transmission were primarily due to increased earnings from TransGas and
Portland. The increase in 2002 earnings over 2001 was mainly due to the Fair
Return decision, higher incentive earnings from Wholly-Owned Pipelines and
higher earnings from TCPL's investment in Great Lakes.

WHOLLY-OWNED PIPELINES - FINANCIAL REVIEW

ALBERTA SYSTEM Net earnings of $190 million in 2003 were $24 million lower than
2002 and $14 million lower than 2001. The decrease compared to 2002 and 2001 was
primarily due to lower earnings resulting from the 2003 Settlement reached
between TCPL and its customers in February 2003. The 2003 Settlement included a
fixed revenue requirement component, before non-routine adjustments, of $1.277
billion compared to $1.347 billion in 2002 and $1.390 billion in 2001. The
company initially expected the lower negotiated 2003 revenue requirement would
reduce 2003 earnings by approximately $40 million relative to 2002. However,
higher incentive earnings were realized in 2003, primarily from lower financing
and operating costs which partially offset the expected reduction.

The Alberta System is one of the largest volume carriers of natural gas in North
America and delivered 3,883 Bcf of natural gas in 2003, compared to deliveries
of 4,146 Bcf in 2002 and 4,059 Bcf in 2001. The volumes transported by the
Alberta System in 2003 represented approximately 16 per cent of total North
American natural gas production and 66 per cent of the natural gas produced in
the WCSB.

The Alberta System is regulated by the EUB primarily under the provisions of the
Gas Utilities Act (Alberta) (GUA) and the Pipeline Act (Alberta). Under the GUA,
the rates, tolls and other charges, and terms and conditions of service are
subject to approval by the EUB.

CANADIAN MAINLINE The Canadian Mainline generated net earnings of $290 million
in 2003, a decrease of $17 million compared to 2002 and an increase of $16
million over 2001 earnings. The decrease in net earnings in 2003 from 2002 and
the increase in net earnings from 2001 to 2002 was primarily due to recognition
of incremental earnings for 2001 and 2002 as a result of the NEB's Fair Return
decision in June 2002. This decision included an increase in the deemed common
equity ratio to 33 per cent from 30 per cent, effective January 1, 2001, and
resulted in additional net earnings of $16 million for the year ended December
31, 2001, that the company recognized in June 2002. Net earnings in 2003 also
reflect the continued decrease in average investment base. These factors were
partially offset by an increase in the NEB-approved rate of return on common
equity to 9.79 per cent in 2003 from 9.53 per cent in 2002. The increase in 2003
earnings relative to 2001 is primarily due to the NEB's Fair Return decision
which provided for an increase in deemed common equity to 33 per cent.

Annual deliveries of natural gas on the Canadian Mainline totalled 2,628 Bcf in
2003, compared to 2,630 Bcf in 2002 and 2,450 Bcf in 2001. In 2003, deliveries
to export border points comprised 51 per cent of total deliveries compared to 53
per cent in 2002 and 50 per cent in 2001.

The Canadian Mainline is regulated by the NEB. The NEB sets tolls, which provide
TCPL the opportunity to recover projected costs of transporting natural gas and
also provide a return on the Canadian Mainline


                                      M-9


average investment base. New facilities are approved by the NEB before
construction begins. Changes in investment base, the rate of return on common
equity, the level of deemed common equity and the potential for incentive
earnings affect the net earnings of the Canadian Mainline.

WHOLLY-OWNED PIPELINES - DEVELOPMENTS

REGULATORY In 2003, TCPL focused much of its efforts on the evolution of its
regulated business model. This evolution includes proposed changes to TCPL's
Canadian regulated pipeline business that would provide the company an
opportunity to earn a competitive return and enhance its ability to compete for
future market demand and natural gas supply while bringing benefits to
customers. This regulated business model is intended to advance TCPL's rate and
service offerings on all four of the company's wholly-owned pipelines.

In 2003, TCPL's activities included its appeal of the NEB's Fair Return Review
and Variance decision, the EUB's GCOC Proceeding, preparation of the 2004
Mainline Tolls and Tariff Application, the Alberta System's 2004 GRA, the
Alberta System 2003 Tariff Application which was approved by the EUB and
continued discussion with industry stakeholders.

In February 2003, the NEB denied the request TCPL made in September 2002 for a
Review and Variance of the Fair Return decision. TCPL maintains that the Fair
Return decision issued in June 2002 does not recognize the long-term business
risks of the Canadian Mainline. The company ultimately initiated an appeal of
the NEB's decision not to review and vary the Fair Return decision, with the
Federal Court of Appeal. In May 2003, the Federal Court of Appeal granted TCPL
leave to appeal the NEB's February 2003 decision. The appeal was heard in
February 2004 and TCPL awaits the judgment.

The NEB hearing for TCPL's 2003 Canadian Mainline Tolls and Tariff Application
began in February 2003. In its July 2003 decision on the application, the NEB
approved all key components of the application including an increase in the
composite depreciation rate to 3.42 per cent from 2.89 per cent, the
introduction of a new tolling zone in southwestern Ontario, an increase to the
IT bid floor price and the continuation of the Fuel Gas Incentive Program. The
2003 tolls resulting from this decision are interim pending the disposition of
TCPL's appeal to the Federal Court of Appeal regarding the NEB's Review and
Variance decision.

In July 2003, TCPL, along with other utilities, filed evidence in the EUB's GCOC
Proceeding. In this application, TCPL requested a return of 11 per cent on a
deemed common equity of 40 per cent for the Alberta System in 2004. The EUB
expects to adopt a standardized approach to determining the rate of return and
capital structure for all utilities under its jurisdiction at the conclusion of
this proceeding. Oral testimony in the hearing concluded January 16, 2004.
Written argument and reply argument are to follow with an EUB decision expected
in third quarter 2004.

In September 2003, TCPL filed with the EUB Phase I of the Alberta System's 2004
GRA, consisting of evidence in support of the applied-for rate base and revenue
requirement. The company applied for a composite depreciation rate of 4.13 per
cent compared to the current depreciation rate of 4.00 per cent. In November
2003, the company filed Phase II of the application, which primarily deals with
rate design and services. EUB hearings to consider the 2004 GRA Phase I and
Phase II applications are scheduled to commence, in Calgary, on April 1, 2004
and June 1, 2004, respectively.

The Canadian Mainline 2004 Tolls and Tariff Application was filed with the NEB
on January 26, 2004. In this application, TCPL requested a Fuel Gas Incentive
Program, establishment of a new non-renewable firm transportation (FT) service,
modifications to the existing short-term FT service and recovery of costs of
service including an 11 per cent return on deemed common equity of 40 per cent.


                                      M-10


OPERATIONAL EXCELLENCE TCPL continued its commitment to operational excellence
in 2003 by advancing initiatives that will improve the company's ability to
provide low-cost, reliable and responsive service to customers. TCPL continues
to pursue this strategy in order to become the preferred company that customers
choose to connect new gas supplies and markets.

In 2003, TCPL exceeded its performance targets of reducing operating and
maintenance costs by rationalizing maintenance and streamlining the delivery of
services. The company met ongoing goals in the management of greenhouse gases.
TCPL also achieved exceptional plant operating performance, as measured by the
number of operational perfect days on both the Alberta System and the Canadian
Mainline. Also in 2003, TCPL improved customer satisfaction with implementation
of new systems to consolidate and enhance management of customer transactions.
Customer feedback indicates this system improvement was very well received.

In 2004, TCPL will continue to focus efforts on cost reduction, operational
reliability, and environmental and safety performance. The company has
established 2004 operating and maintenance budgets with an expectation of
further productivity gains, while operating reliability targets have increased
and greenhouse gas emissions management programs continue to receive focused
attention. Additional effort will be undertaken in 2004 with respect to
improving contractor safety performance.

SUPPLY In 2003, TCPL continued to connect incremental natural gas supply in
the WCSB, in Alberta and from B.C. Additional production from the Sierra area
of B.C. is expected to commence delivery to Alberta in early 2004.

The timely connection of these volumes has allowed TCPL's customers to take
advantage of premium gas price environments. TCPL will continue to grow by
seeking new opportunities to connect additional gas supplies.

MARKETS TCPL continues to pursue growth opportunities within existing and new
natural gas markets. In 2003, TCPL took steps to expand its pipeline system in
western Canada through the pending acquisition of the Simmons Pipeline System,
via the execution of a long-term transportation service arrangement with
TransCanada Pipeline Ventures Limited Partnership (Ventures LP) and through
expansion of the Alberta System. These arrangements, upon regulatory approval
expected in 2004, will allow TCPL to increase the company's delivery capacity
into the rapidly expanding area of Fort McMurray, Alberta to approximately 700
million cubic feet per day (MMcf/d).

TCPL also continues to pursue increased deliveries in response to market
growth in both Canada and the U.S. While customers have been repositioning
their pipeline contracts away from long haul arrangements originating in
Alberta to short haul contracts originating at local market hubs, the
underlying markets continue to grow.

FOOTHILLS ACQUISITION In August 2003, TCPL acquired the remaining interests in
Foothills previously not held by the company for $259 million, including
assumption of $154 million of Foothills' debt. As a result, TCPL now owns 100
per cent of Foothills. Foothills and its subsidiaries hold the certificates to
build the Canadian portion of the Alaska Highway Pipeline Project which would
bring Prudhoe Bay natural gas from Alaska to markets in Canada and the U.S. The
"prebuild" portion of this project has been operating for more than 20 years,
moving Alberta natural gas to U.S. markets in advance of flows from Alaska.
Subsidiaries of Foothills and TCPL also hold certificates to build the Alaskan
section of this project.

WHOLLY-OWNED PIPELINES - OUTLOOK

TCPL's Gas Transmission business has a long history of providing pipeline
capacity to markets and connecting natural gas supply for the company's
customers. As the marketplace has evolved and competition has grown, the
Wholly-Owned Pipelines have focused on providing market-responsive products and
services, competitive cost-effective structures, and the highest levels of
reliability to customers.


                                      M-11


In 2004, the Wholly-Owned Pipelines will continue to focus on achieving
additional efficiency improvements in all aspects of the business by maintaining
focus on operational excellence and leveraging technological advancements. TCPL
will also continue to work collaboratively with all stakeholders in resolving
jurisdictional issues, advancing changes to the regulated business model and
addressing fair return challenges.

Looking forward, as the supply/demand balance tightens, producers will continue
to explore and develop new fields, as well as unconventional supply such as gas
production from coal bed methane reserves. In addition, stakeholder support is
expected to grow for proposals to access Northern gas from the Mackenzie Delta
and Alaska North Slope. TCPL will seek to connect these additional natural gas
supplies to the Alberta System.

TCPL's earnings from its Wholly-Owned Pipelines are primarily determined by the
average investment base, return on common equity, deemed common equity and
opportunity for incentive earnings. In the short to medium term, the company
expects modest growth from these mature assets and therefore anticipates
continued decline in the average investment base. Accordingly, without an
increase to return on equity, deemed common equity, or incentive opportunities,
future earnings are anticipated to decrease. However, these mature assets will
continue to generate strong cash flows that can be redeployed to other projects
offering higher returns. Under the current regulatory model, earnings from the
Wholly-Owned Pipelines are not affected by short-term fluctuations in the
commodity price of natural gas, changes in throughput volumes or changes in FT
contract levels.

EARNINGS In 2004, net earnings from Wholly-Owned Pipelines will depend in large
part on the outcome of the appeal of the NEB's Fair Return Review and Variance
decision, the EUB's GCOC hearing, the 2004 Mainline Tolls and Tariff Application
and the Alberta System's 2004 GRA. In the absence of favorable rulings in these
applications, the company expects 2004 earnings to be lower compared to 2003
earnings, primarily due to the combined effect of a decrease in rate of return
on common equity in 2004 (Canadian Mainline 2003 - 9.79 per cent versus 2004 -
9.56 per cent based on the NEB formula) and lower average investment bases.
Although 2004 earnings may be lower than 2003 earnings, Wholly-Owned Pipelines
will continue to generate strong cash flow.

CAPITAL EXPENDITURES Total capital spending for the Alberta System, Canadian
Mainline and BC System during 2003 was approximately $100 million. Capital
spending in 2004, including the Foothills System, is expected to approximately
double the expenditures in 2003, primarily due to higher capacity capital
spending.

WHOLLY-OWNED PIPELINES - BUSINESS RISKS

COMPETITION TCPL faces competition at both the supply end and the market end of
its systems. The competition is a result of other pipelines accessing an
increasingly mature WCSB. The construction of the Alliance Pipeline, a natural
gas pipeline from northeast B.C. to the Chicago area, and the continued
expiration of transportation contracts have resulted in significant reductions
in firm contracted capacity on both the Alberta System and the Canadian
Mainline. The Canadian Mainline absorbs the bulk of any volume swings in the
WCSB.

As of December 2002, the WCSB had estimated remaining discovered natural gas
reserves of 57 trillion cubic feet and a reserves-to-production ratio of
approximately nine years at current levels of production. Additional reserves
are continually being discovered to maintain the reserves-to-production ratio at
close to nine years. Natural gas prices in the future are expected to be higher
than long-term historical averages due to a tighter supply/demand balance which
should stimulate exploration and production in the WCSB. However, the WCSB
supply is expected to remain essentially flat.

TCPL's Alberta System provides the major natural gas gathering and export
transportation capacity for the WCSB. It does so by connecting to most of the
gas processing plants in Alberta and then transporting natural gas for domestic
and export deliveries. The Alberta System faces competition primarily from the


                                      M-12


Alliance Pipeline. In addition, the Alberta System has faced, and will continue
to face, increasing competition from other pipelines.

The Canadian Mainline is TCPL's cross-continent natural gas pipeline serving
mid-western and eastern markets in Canada and the U.S. TCPL continues to face
competition for transportation services to eastern Canadian markets and U.S.
export points. The demand for natural gas in TCPL's key eastern markets is
expected to continue to increase, particularly to meet the expected growth in
gas-fired power generation. Although there are opportunities to increase market
share in Canadian and U.S. export markets, TCPL faces significant competition in
these regions. Consumers in the U.S. Northeast have access to an array of
pipeline and supply options. Eastern Canadian markets that have historically
received Canadian supplies only from TCPL are capable of receiving supplies from
new pipelines into the region that can source both western Canadian and U.S.
supplies.

The Canadian Mainline has experienced reductions in long haul FT contracts for
deliveries originating at the Alberta border and in Saskatchewan of
approximately 2.5 Bcf/d, or approximately 36 per cent of its capacity since the
1998/1999 contract year. Looking forward, in the short to medium term, there is
limited opportunity to reduce tolls by increasing long haul volumes on the
Canadian Mainline. The utilization of the Canadian Mainline is not expected to
increase in the short to medium term as any additional supply from the WCSB is
expected to be absorbed by demand growth within western Canada and by higher
flows on other pipeline systems.

TCPL will continue to work with stakeholders in 2004 to advance various aspects
of the company's regulated business model for the Alberta System, Canadian
Mainline, Foothills System and the BC System.

FINANCIAL RISK The company remains concerned about the long-term implications of
a financial return that discourages additional investment in existing Canadian
natural gas transmission systems. TCPL has applied for a return of 11 per cent
on 40 per cent deemed common equity, both to the NEB in the 2004 Mainline Tolls
and Tariff Application and to the EUB in the Alberta System's application in the
GCOC Proceeding. The outcome of the Federal Court of Appeal hearing regarding
the NEB's Review and Variance decision as well as the GCOC proceeding, could
have a significant impact on the financial returns for, and future investment
in, TCPL's Canadian pipelines.

The company is cognizant of the views and shares the concerns of credit rating
agencies regarding the Canadian regulatory environment. Credit ratings and
liquidity have risen to the forefront of investor attention. In light of the
developments in the Canadian regulatory environment, there exists a view that
current Canadian regulatory policy is eroding the credit worthiness of utilities
which, over the long term, could make it increasingly difficult for utilities to
access capital on reasonable terms.

SAFETY TCPL worked closely with regulators, customers and communities during
2003 to ensure the continued safety of employees and the public. In 2003, two
line breaks occurred in a remote area of Alberta resulting in a short-term
reduction in natural gas shipments. Neither incident resulted in injuries or
damage to public property. Under the current regulatory models, expenditures on
pipeline integrity have no negative impact on earnings. The company expects to
spend approximately $76 million in 2004 on pipeline integrity compared to $73
million in 2003. TCPL continues to use a rigorous risk management system that
focuses spending on issues and areas that have the largest impact on maintaining
or improving the reliability and safety of the pipeline system.

ENVIRONMENT In 2003, TCPL continued to conduct activities to increase
environmental protection through proactive sampling, remediation and monitoring
programs. Compressor stations on the Canadian Mainline have been assessed
through the company's Site Assessment, Remediation & Monitoring (SARM) program.
In 2003, approximately $5 million was invested in improved environmental
protection measures at identified TCPL locations. This program of actively
assessing and addressing environmental issues will continue into the future. In
addition, the decommissioning of six Canadian Mainline compressor plants and
four Alberta sites was undertaken in 2003, effectively remediating each site.

OTHER GAS TRANSMISSION - FINANCIAL REVIEW

Other Gas Transmission is comprised of TCPL's direct and indirect investment in
various natural gas pipelines and gas transmission related businesses. It also
includes project development activities related to TCPL's pursuit of new natural
gas pipeline and gas transmission related opportunities throughout North
America, including the North and LNG.

TCPL's net earnings from Other Gas Transmission in 2003 were $116 million
compared to $109 million and $82 million in 2002 and 2001, respectively. The
increased net earnings of $7 million in 2003 compared to 2002 were due to higher
earnings from TransGas as a result of recognition of an adjustment for future
income tax benefits of $11 million and higher contractual tolls in 2003. In
addition, earnings from Portland were higher compared to 2002 due to the impacts
of a rate settlement in early 2003 and TCPL increasing its ownership interest in
2003. Earnings from Ventures LP was also higher due to higher contracted
transportation volumes. These increases were partially offset by the impact of a
substantially weaker U.S. dollar, higher project development costs and lower
earnings from CrossAlta Gas Storage & Services Ltd. (CrossAlta) due to lower
storage margins as a result of unfavourable market conditions. In addition, 2002
earnings included TCPL's $7 million share of a favourable ruling for Great Lakes
related to Minnesota use tax paid in prior years.

Other Gas Transmission net earnings of $109 million in 2002 increased by $27
million compared to 2001. This increase resulted from higher earnings from U.S.
investments which included TCPL's $7 million share of the favourable ruling for
Great Lakes related to Minnesota use tax paid in prior years, increased
ownership interests in Iroquois and Portland acquired in mid-2001, higher
transportation margins and favourable movements in exchange rates. Earnings from
CrossAlta were also higher due to higher storage margins, increased storage
capacity and reduced operating expenses. In addition, there was reduced spending
on Northern Development in 2002 and increased earnings from Ventures LP.

OTHER GAS TRANSMISSION - DEVELOPMENTS

In 2003, TCPL increased its ownership interest in Portland, secured a
position in the Mackenzie Gas Pipeline Project and pursued LNG projects by
conducting preliminary assessments of LNG facilities in the Northeast U.S.
and eastern Canada.

TC PIPELINES, LP TCPL holds a 33.4 per cent interest in TC PipeLines, LP that in
turn holds a 30 per cent interest in Northern Border Pipeline Company (Northern
Border) and a 49 per cent interest in Tuscarora Gas Transmission Company
(Tuscarora). In July 2003, TC PipeLines, LP increased its quarterly distribution
to US$0.55 per unit from US$0.525 per unit. This represents the fourth increase
in the partnership's quarterly cash distribution since the commencement of
operations in May 1999.

In December 2003, Tuscarora received management approval for an expansion
project which will provide for approximately 57 MMcf/d incremental capacity on
its system. Total capital cost is estimated to be approximately US$16.6 million,
and the expansion is scheduled to commence service in November 2005.

IROQUOIS The Eastchester expansion project experienced several delays throughout
2003 primarily due to construction complications. However, by the end of 2003,
Iroquois had successfully resolved the majority of these construction issues and
placed the expansion facilities into service in February 2004. The expansion is
the first major natural gas transmission pipeline to be built into New York City
in approximately 40 years.

In October 2003, the Federal Energy Regulatory Commission (FERC) approved
Iroquois' mainline rate settlement, which was filed in August 2003. The
settlement is effective from January 1, 2004 through December 2007, during which
period Iroquois will reduce rates by approximately 13 per cent. The settlement
does not establish rates, terms or conditions for the Eastchester expansion,
which was covered


                                      M-14


by a separate rate application filed with the FERC in January 2004. The FERC has
issued an order that accepts Iroquois' application effective July 1, 2004
subject to refund and conditions, and establishing hearing procedures.

PORTLAND In September 2003, the company purchased an additional 10.1 per cent
ownership interest in Portland for approximately US$47 million, including
assumed debt of approximately US$28 million. In December 2003, the company
purchased a further 18.3 per cent interest for approximately US$82 million,
including assumed debt of approximately US$50 million, thus increasing its total
ownership interest in Portland to 61.7 per cent. Subsequent to this acquisition,
Portland was fully consolidated in the company's financial statements, with 38.3
per cent reflected in non-controlling interests.

Portland and customer representatives reached an agreement on new tolls and FERC
approved it in its entirety in January 2003. The agreement is effective from
April 1, 2002 through April 1, 2008. Lower depreciation rates and revised tolls
provided for in the agreement have had a positive impact on Portland's earnings
in 2003.

TQM In January 2003, TCPL began performing the majority of operational and
administrative activities for TQM to allow TQM to benefit from best practices
employed in the industry at the lowest possible cost. As a result of this
reorganization, TQM has realized cost savings, which, in accordance with its
incentive agreement, will be shared among its customers and owners.

NORTHERN DEVELOPMENT In 2003, TCPL continued to pursue pipeline opportunities to
move both Mackenzie Delta and Alaska North Slope natural gas to markets
throughout North America. TCPL worked with key stakeholders with the objective
of participating in any potential pipeline project.

TCPL, the Mackenzie Delta gas producers and the APG reached funding and
participation agreements in June 2003 that enable the APG to become a full
participant in the proposed Mackenzie Gas Pipeline Project. This project would
result in a natural gas pipeline being constructed from Inuvik, Northwest
Territories to the northern border of Alberta, where it would then connect with
the Alberta System. TCPL has agreed to finance the APG for its one-third share
of project definition costs. This share is currently expected to be
approximately $90 million over three years. This loan will be repaid from the
APG's share of future pipeline revenues. In the year ended December 31, 2003,
TCPL funded $34 million of this loan. Under the terms of the agreement, TCPL
gains an immediate opportunity to acquire up to five per cent equity ownership
of the pipeline at the time of construction. In addition, TCPL also gains
certain rights of first refusal to acquire 50 per cent of any divestitures of
existing partners and an entitlement to obtain a one-third interest in all
expansion opportunities once the APG reaches a one-third share, with the
producers and the APG sharing the balance.

TCPL continued to work with the Alaska Highway Pipeline stakeholders in 2003 to
advance that project. Resolution of Foothills' Special Charge was reached with
Foothills shippers and the Canadian Association of Petroleum Producers, and
subsequently approved by the NEB, in March 2003. The resolution waives
Foothills' obligation to repay all past and future Special Charge collections
when Alaskan gas starts flowing on the Foothills System. In October 2003, the
Government of Canada, once again, reaffirmed its preference to utilize the
framework provided in the Northern Pipeline Act which granted Foothills the
certificates to transport Alaskan gas across Canada. In January 2004, Foothills
and the Kaska First Nation signed an Agreement-in-Principle that provides the
framework for a future participation agreement. The Agreement-in-Principle marks
the completion of the second stage of negotiations that is expected to lead to a
participation agreement for the Alaska Highway Pipeline Project.

LIQUEFIED NATURAL GAS In September 2003, TCPL and ConocoPhillips announced the
Fairwinds partnership to jointly evaluate a site in Harpswell, Maine for the
development of an LNG regasification facility. The residents of the Town of
Harpswell are expected to vote on leasing a town-owned site for the facility. If
leasing of the site is approved and necessary regulatory approvals are
subsequently received, construction of the LNG facility could begin in 2006 with
the facility becoming operational in 2009. Natural gas from the LNG facility
would be delivered by pipeline to markets in the northeast U.S.


                                      M-15


OTHER GAS TRANSMISSION - STRATEGY AND OUTLOOK

TCPL continues to actively pursue natural gas pipeline and gas transmission
related development and acquisition opportunities in North America, where these
opportunities are driven by strong customer demand and sound economics. With
TCPL's strong financial position, the company is poised to capitalize on future
acquisition and development opportunities. The company will continue to evaluate
options in a disciplined fashion to maintain a strong financial position.

World geo-political events will have an impact on the level of development of
future and existing natural gas supplies worldwide. This could directly impact
TCPL, with the company expanding existing facilities across North America and
being involved in the development of alternative natural gas transportation
solutions as producers access natural gas reserves in the North and Atlantic
Canada.

TCPL is committed to play a key role in Northern gas development. While there
are many issues to be resolved before this moves forward, TCPL has competitive
advantages including expertise in the design, construction and operation of
large diameter pipelines in cold weather conditions. TCPL is also the leading
operator of large natural gas turbine compressor stations, owns and operates one
of the largest, most sophisticated, remote-controlled pipeline networks in the
world, and has a solid reputation for safety and reliability. This positions the
company well to play a key role in bringing Northern gas to market.

Excluding the impact of the recognition of the $11 million TransGas future tax
benefits in 2003, the net earnings outlook for Other Gas Transmission in 2004 is
expected to be similar to 2003. Net earnings will be affected by factors such as
the performance of the Canadian dollar relative to the U.S. dollar and the level
of project development costs.

OTHER GAS TRANSMISSION - BUSINESS RISKS

FOREIGN EXCHANGE A significant amount of the earnings in Other Gas Transmission
is generated from U.S. pipeline affiliates. The performance of the Canadian
dollar relative to the U.S. dollar would either positively or negatively impact
this business segment's results.

THROUGHPUT RISK Iroquois, Portland and Tuscarora all have long-term demand
charge contracts in place with customers and as such, are virtually unaffected
by changes in throughput. As transportation contracts expire on Great Lakes and
Northern Border, these entities will be more exposed to throughput risk and
their revenues will more likely experience increased variability. Throughput
risk is created by supply availability, economic activity, weather variability,
pipeline competition and pricing of alternative fuels.

INSURANCE, EMPLOYEE BENEFITS AND INTEREST RATES Insurance costs continue to rise
with the increasing risk of terrorism and sabotage in recent years. The costs of
employee benefits, particularly in the U.S., also continue to increase. At the
same time, interest rates remain near historical lows. If these insurance and
employee benefits costs continue to rise and the economic recovery results in
increased interest rates, earnings of Other Gas Transmission could be negatively
impacted.

REGULATION The U.S. partially-owned pipelines are regulated by the FERC while
the Canadian partially-owned pipeline is regulated by the NEB. These regulators
play a significant role in approving the pipelines' respective returns on
equity, capital structures, tolls and system expansions.

POWER

HIGHLIGHTS

EARNINGS The Power segment made a significant contribution to TCPL's earnings in
2003. Net earnings increased 51 per cent from 2002 due in part to the
acquisition of Bruce Power and increased earnings from Western Operations.

BRUCE POWER TCPL completed the acquisition of a 31.6 per cent equity interest in
Bruce Power, the operator and lessee of the Bruce nuclear power facility in
Ontario. This acquisition indirectly increased TCPL's nominal generating
capacity by 1,000 MW in February 2003. The return to service of Bruce Power A
Unit 4 in fourth quarter 2003 and Bruce Power A Unit 3 in first quarter 2004
increased TCPL's 31.6 per cent share of the nominal generating capacity of Bruce
Power to 1,474 MW.

EXPANDING ASSET BASE In June 2003, TCPL announced its plans to develop the 550
MW Becancour natural gas-fired cogeneration power plant in Quebec. The project
which is estimated to cost approximately $550 million, including capitalized
interest, is expected to be placed in-service in late 2006. In October 2003,
TCPL and Grandview Cogeneration Corporation, an affiliate of Irving Oil Limited
(Irving), announced an agreement to construct a 90 MW natural gas-fired
cogeneration power plant on the site of the Irving Oil Refinery in Saint John,
New Brunswick. The plant is expected to be placed in-service by the end of 2004
at a total estimated cost of approximately $90 million. The company placed the
Bear Creek plant in Alberta in-service in first quarter 2003 and expects the
MacKay River plant to be commercially in-service in first quarter 2004.


                                      M-18


OPERATIONAL EXCELLENCE Average plant availability, excluding Bruce Power, was 94
per cent in 2003 compared to 96 per cent in 2002. This slight decrease resulted
primarily from scheduled maintenance at some of the plants in Western
Operations. Including Bruce Power, average plant availability decreased to 90
per cent for 2003 as a result of scheduled maintenance on two Bruce Power B
units.

----------------------------------------------------------------------------------------


TCPL's Power business contributed $220 million of net earnings in 2003, an
increase of $74 million or 51 per cent compared to earnings of $146 million in
2002. This increase is primarily attributable to TCPL's acquisition in February
2003 of a 31.6 per cent interest in Bruce Power and higher contributions from
Western Operations. Partially offsetting the increase were lower earnings from
Eastern Operations and higher general, administrative and support costs.

The increase in general, administrative and support costs in 2003 compared to
the two prior years reflects higher support costs associated with the company's
focus on growth in Power.

Power's net earnings of $146 million in 2002 decreased $22 million compared to
2001. This decrease primarily reflected TCPL's ability to capitalize on market
opportunities in both Western and Eastern Operations in 2001 which did not exist
in 2002.

(7)  At December 31, 2003, TCPL operated and managed Power LP and held a 35.6
     per cent ownership interest in Power LP. The volumes in the table represent
     100 per cent of plant capacity.

POWER - DEVELOPMENTS

TCPL's Power segment had another strong year in 2003. The Power segment
continued to grow, completing the acquisition of a 31.6 per cent interest in
Bruce Power in February 2003, placing the Bear Creek plant in-service in 2003,
and completing construction of the MacKay River facility at the end of 2003.
TCPL also increased its presence in eastern Canada, announcing plans to
construct two power plants, Becancour in Quebec and Grandview in New Brunswick.

TCPL continues to utilize its competitive strengths to seek quality
acquisitions, greenfield development opportunities and expansion of the
company's existing businesses to complement the current portfolio of power
generation assets. TCPL is generally able to expand the company's portfolio of
power plants while mitigating excessive price risk through the long-term sale of
electricity and steam/heat to the adjacent


                                      M-20


industrial customers for a portion of the plant output while, at the same time,
retaining a certain amount of merchant power capacity to be sold to other
customers.

WESTERN OPERATIONS

The focus of Western Operations is to optimize and expand the existing asset
base and maximize asset value through a combination of long- and short-term
sales contracts and low-cost generation and supply.

Western Operations has two main components - Western Marketing and Plant
Operations. Western Marketing consists of the power marketing operations
originating out of the Calgary office, including marketing of uncommitted
generation from the Alberta plants and the purchase and resale of electricity
related to the Sundance PPAs. Western Marketing also participates in marketing
electricity in western Canada and throughout the U.S. from Washington state to
Wisconsin. Plant Operations consists of contributions from the Alberta power
plants, the ManChief plant in Colorado, and fees earned to manage and operate
Power LP's seven plants.

WESTERN MARKETING While a significant portion of Western Plant Operations'
generation is sold under long-term contracts to mitigate price risk, some power
is intentionally not sold under long-term contracts. The Western Marketing
group's primary function is to manage these open positions to maximize the value
of Power's assets through marketing and trading activities as well as through
operational optimization. In order to mitigate market price risk, Western
Operations has sold approximately 84 per cent of the total generation for 2004
and 70 per cent of the expected, average combined total power supply for the
next three years. Western Operations' largest power supply is its Sundance PPAs.
TCPL has sold essentially all of the Sundance PPA power supply in 2004 and 69
per cent and 49 per cent of the expected combined power supply for 2005 and
2006, respectively. Western Marketing continues to secure additional long-term
sales contracts for the remaining power supply.

PLANT OPERATIONS Plant Operations is another area of success and growth for
TCPL. The expansion of this area is consistent with TCPL's focus on capitalizing
on the company's expertise in developing new projects and maintaining its
position as a prominent player in the Alberta market. The Bear Creek plant began
commercial operations in March 2003. This 80 MW cogeneration facility near
Grande Prairie, Alberta sells the majority of its power to Weyerhaeuser's Grande
Prairie Pulp Mill, as well as Weyerhaeuser's other Alberta facilities.

Construction of the MacKay River plant was completed in fourth quarter 2003 and
the plant is expected to be in-service in first quarter 2004. The 165 MW
cogeneration facility near Fort McMurray, Alberta, will provide electricity and
steam to Petro-Canada's adjacent in-situ oil sands operations. The MacKay River
plant increases TCPL's directly controlled supply in Alberta to more than 1,300
MW.

Plant Operations is committed to an operational excellence model that provides
low-cost, reliable operating performance at each of its plants. The Redwater and
Carseland plants, both completing their second year of operation, operated very
well in 2003. Bear Creek is still in its first year of operations and is in the
process of ongoing operational optimization. ManChief, which was acquired in
November 2002, is another solid performing asset in TCPL's power generation
portfolio. The entire capacity is sold under long-term tolling contracts that
expire in 2012.

Operating and other income from Western Operations increased by 22 per cent to
$160 million in 2003 from $131 million in 2002 due primarily to a positive $31
million pre-tax ($19 million after tax) settlement in June 2003 with a former
counterparty that defaulted in 2001 under power forward contracts. A full year
of earnings from the ManChief plant, which was acquired in late 2002, higher
contributions from the Sundance PPAs reflecting lower transmission costs, and
higher earnings from the Alberta plants also contributed to higher operating
income. Offsetting these increases were the effects in 2003 of lower prices
achieved on the overall sale of power and the higher cost of natural gas fuel at
the carbon black facility.

While the average Alberta Pool Price for 2003 was $63/megawatt hour (MWh)
compared to $44/MWh in 2002, margins were lower in 2003 due to lower realized
prices and reduced market liquidity.


                                      M-21


Operating income from Western Operations decreased $18 million to $131 million
in 2002 when compared to 2001. Market opportunities that existed in 2001
resulting from high power prices (average Alberta Pool Price of $71/ MWh in
2001) and price volatility in western Canada and the Pacific Northwest regions
did not carry over into 2002. However, this was partially offset by income from
the acquisition of the Sundance B PPA, ManChief, and the placing in-service of
the Redwater and Carseland plants.

EASTERN OPERATIONS

Power's Eastern Operations is focused on the New England and New York
deregulated power markets and consists of Power Marketing and Power Generation
operations, both of which operate as one integrated business. Eastern Operations
also include the company's development opportunities in Ontario and other
provinces in eastern Canada.

Over the past five years, TransCanada Power Marketing Limited (TCPM), an
affiliate located in Westborough, Massachusetts, has successfully navigated
through New England's deregulation process and firmly established itself as a
leading power generator and energy provider in the New England power market.
TCPL continues to seek out opportunities to add generation capacity to the
existing asset base and leverage off this experience in expanding its presence
in the Ontario market.

POWER MARKETING TCPL's continued success and growth in the northeast U.S. is the
direct result of an efficient marketing operation which is conducted through
TCPM. TCPM is focused on selling power under contract to wholesale, commercial
and industrial customers while managing a portfolio of power supplies sourced
from both its own generation assets and wholesale power purchases. TCPM is a
full service provider offering different products and services to assist
customers in managing their power supply and power prices in deregulated power
markets. Through active portfolio management, TCPM has positioned itself to
capture market opportunities as they arise, while reducing downside exposure.
Included in the additional power supply is TCPM's purchase of 100 per cent of
the output of the 64 MW natural gas-fired combined-cycle plant located in
Castleton-on-Hudson, New York (Castleton), which is owned by Power LP.

POWER GENERATION Eastern U.S. power generation assets include Ocean State Power
(OSP), a 560 MW natural gas-fired plant located in Rhode Island, and the 60 MW
Curtis and Palmer hydroelectric facilities (Curtis Palmer) near Corinth, New
York. Of the total OSP output, 76.5 per cent is sold under long-term purchase
arrangements to TCPM with the remainder sold to Boston Edison Company. Output
from Curtis Palmer is sold into the New York market under a fixed-price,
long-term power purchase agreement with Niagara Mohawk Power Corporation for an
expected term of more than 25 years. Curtis Palmer has a high capacity factor
due to its strategic location just downstream of certain water storage
facilities on the Hudson River, but earnings are subject to seasonal and annual
variations in water levels.

Operating income for 2003 from Eastern Operations was $127 million compared to
$149 million in 2002. The $22 million decrease was primarily due to the impact
of higher natural gas fuel costs at OSP resulting from an arbitration process
and the unfavourable impact of a weaker U.S. dollar. Partially offsetting these
decreases were incremental earnings from the growth in volumes and margins in
the eastern U.S. retail business which is focused on sales to large commercial
and industrial customers. In addition, 2003 had higher earnings from Curtis
Palmer as a result of above average water flows and revenue earned from a
temporary generation facility built and operated in Cobourg, Ontario during the
summer of 2003.

Operating income of $149 million in 2002 was slightly lower than the
unprecedented $159 million of earnings in 2001. The decrease year over year was
primarily due to the ability throughout 2001 to capitalize on price volatility
that was less prevalent in 2002, partially offset by a full year of earnings
from the Curtis Palmer hydroelectric facilities purchased in July 2001.

The long-term natural gas supply for OSP is subject to a yearly price
renegotiation. If OSP and the suppliers are unable to reach an agreement on
price in a given year, the matter is settled by arbitration.


                                      M-22


OSP is currently in its third such arbitration with its natural gas fuel
suppliers. The first two arbitration decisions substantially increased OSP's
natural gas fuel costs.

DEVELOPMENT OPPORTUNITIES IN EASTERN CANADA In October 2003, TCPL and an
affiliate of Irving announced an agreement to build a 90 MW natural gas-fired
cogeneration power plant in Saint John, New Brunswick to be developed and owned
by TCPL. Under a 20 year tolling arrangement, Irving will provide fuel for the
plant and contract for 100 per cent of the plant's heat and electricity output.
Construction of the facility began in December 2003 and is expected to be
in-service by the end of 2004.

In June 2003, TCPL announced its plans to develop a 550 MW natural gas-fired
cogeneration power plant in Quebec. The power plant will be located in the
Becancour Industrial Park, near Trois-Rivieres and will supply its entire power
output to Hydro-Quebec Distribution under a 20 year power purchase contract. The
plant will also supply steam to certain major businesses located within the
industrial park. Construction of the facility is likely to begin in 2004,
pending receipt of regulatory approvals, and is expected to be in-service in
late 2006.

Power continues to assess the viability of developing a natural gas-fuelled
energy centre to meet electricity needs in downtown Toronto through its
partnership with Ontario Power Generation (OPG) in the Portlands Energy Centre
L.P. Situating generation in downtown Toronto, close to the end user, would help
alleviate current and future transmission issues in the downtown core.

BRUCE POWER INVESTMENT

On February 14, 2003, the company completed the acquisitions of a 31.6 per cent
interest in Bruce Power and a 33.3 per cent interest in Bruce Power Inc., the
general partner of Bruce Power, for $409 million. TCPL also funded a one-third
share ($75 million) of a $225 million accelerated deferred rent payment made by
Bruce Power to OPG.

TCPL acquired the interests as part of a consortium (the Consortium) that
includes Cameco Corporation (Cameco) and BPC Generation Infrastructure Trust, a
trust established by the Ontario Municipal Employees Retirement System. Under
the agreement, the Consortium acquired British Energy (Canada) Ltd., which owned
a 79.8 per cent interest in Bruce Power as well as a 50 per cent interest in the
nine MW Huron Wind L.P. power facility.

Located in Ontario, the Bruce Power facility is made up of two nuclear plants -
Bruce B and Bruce A. Bruce B consists of four reactors, which are currently in
operation, with a capacity of approximately 3,160 MW. Bruce A consists of four
reactors, which up until 2003, were not operating. In 2003, Bruce Power
completed efforts to restart Bruce A Unit 4, followed on January 8, 2004 with
the restart of Bruce A Unit 3. Both units were laid-up in 1998. These two Bruce
A units add 1,500 MW of capacity, bringing Bruce Power's total capacity to 4,660
MW.

Bruce Power is the tenant under a lease with OPG on the Bruce nuclear power
facility. The initial term of the lease expires in 2018 with an option to extend
the lease by up to 25 years. The Bruce nuclear power facility continues to be
managed and operated by the management and staff of Bruce Power. Spent fuel and
decommissioning liabilities remain the responsibility of OPG and, as determined
at the inception of the lease, are covered by the existing lease payments. The
lease agreement with OPG provides for limited adjustments to the base rent every
five years during the initial term of the lease.

TCPL's share of power output during the period of ownership in 2003 was 6,655
gigawatt hours (GWh). This includes power output from Bruce A Unit 4 for
November and December 2003. Bruce A Unit 4 began producing electricity to the
Ontario electricity grid on October 7, 2003 and was considered commercially
in-service on November 1, 2003. Bruce A Unit 3 reconnected to the Ontario
electricity grid on January 8, 2004. Similar to the Bruce A Unit 4 startup
process, after performing and evaluating tests of the shutdown system, Bruce A
Unit 3 was reconnected to the grid and is expected to ramp up to full power in
first quarter 2004. As of December 31, 2003, Bruce Power's cumulative restart
costs for the two Bruce A units were approximately $720 million. Bruce Power
incurred approximately $300 million on the two


                                      M-23


unit restart program for the period February 14, 2003 to December 31, 2003. TCPL
did not provide any funding to Bruce Power subsequent to the acquisition of the
company's ownership interest in February 2003.

Bruce Power spent approximately $147 million on capital expenditures at Bruce B
for the period February 14, 2003 to December 31, 2003, the majority of which was
for safety systems and power uprate programs.

Equity income from Bruce Power is directly impacted by fluctuations in wholesale
spot market prices for electricity as well as overall plant availability, which
in turn, is impacted by scheduled and unscheduled maintenance. To reduce its
exposure to spot market prices, Bruce Power has entered into fixed price sales
contracts for approximately 1,560 MW of output for 2004. The average
availability in 2004 for the six Bruce units is expected to be approximately 80
per cent compared to 85 per cent for the year ended December 31, 2003. This
decrease reflects planned maintenance outages and a test of the Bruce B vacuum
building expected in the fall, which will require all four Bruce B units to be
taken offline for approximately one month. Capital expenditures by Bruce Power
in 2004 are expected to total about $400 million, including approximately $120
million for sustaining capital. TCPL does not expect to provide any funding to
Bruce Power in 2004.

Bruce Power contributed $99 million of pre-tax equity income in 2003. TCPL's
interest in Bruce Power's pre-tax income for 2003 was $65 million. The
additional $34 million of income consisted primarily of the amortization of
purchase price allocations as explained in Note 6 to the December 31, 2003
Consolidated Financial Statements as well as $12 million of capitalized
interest. Bruce Power's average realized price in 2003 from a combination of
contract and spot sales was approximately $48/MWh. Approximately 65 per cent of
Bruce Power's output was sold under longer term contracts in 2003 with the
remainder being sold into Ontario's wholesale spot market.

(1)  TCPL acquired its interest in Bruce Power on February 14, 2003. Bruce
     Power's 100 per cent income before income taxes from February 14 to
     December 31, 2003 was $205 million.

     an explanation of the purchase price amortizations.

POWER LP INVESTMENT

Power LP investment includes the earnings generated from TCPL's 35.6 per cent
investment in TCPL Power, L.P., Canada's largest publicly-held, power-based
income fund. Power LP owns six power plants in Canada and one in the U.S. that
are fuelled by natural gas, waste heat, waste wood or a combination of these.

TCPL acts as manager for Power LP. In this capacity, TCPL manages the operations
and maintenance requirements of Power LP, the fuel supply and associated price
exposure and, when market conditions warrant, TCPL enhances the overall
operating profits of Power LP (i.e. by curtailing certain plants during off-peak
hours and selling the displaced natural gas at attractive market prices),
resulting in increased overall net earnings for Power LP and TCPL.


                                      M-24


Operating and other income in 2003 from TCPL's investment in Power LP remained
consistent with 2002. At December 31, 2003, Power LP units closed at $36.30 on
the Toronto Stock Exchange and TCPL owned approximately 14.0 million units.

POWER VOLUMES AND AVAILABILITY

Volumes have increased 39 per cent to 28,010 GWh in 2003 compared to 20,111 GWh
in 2002 primarily due to the acquisitions of the interest in Bruce Power and
ManChief. Volumes for Eastern Operations increased as a result of growth in the
retail business which is focused on sales to large commercial and industrial
customers. Volumes for Power LP decreased due to curtailments of off-peak
production as a result of higher market prices for natural gas. This curtailment
activity has resulted in lower power output from the Ontario plants compared to
last year; however, overall financial contribution from these plants was higher.

Average plant availability, excluding Bruce Power, was 94 per cent in 2003
compared to 96 per cent in 2002. This slight decrease resulted primarily from
scheduled maintenance at some of the plants in Western Operations. Including
Bruce Power, average plant availability decreased to 90 per cent for 2003 as a
result of scheduled maintenance on two Bruce Power B units.

POWER - STRATEGY AND OUTLOOK

STRATEGY TCPL is committed to growing the Power segment through the pursuit of
quality acquisitions, greenfield development projects and expansion of existing
businesses. Power's growth strategy is to:

o    focus on low-cost base load generation and/or assets underpinned by strong
     contractual arrangements;

o    focus on markets where it has a competitive advantage;

o    use marketing and trading activities to create stable and predictable cash
     flows and optimize asset value; and

o    apply business models that benefit from and support TCPL's strong balance
     sheet.


                                      M-25


OUTLOOK TCPL's Power segment has significant opportunities for growth. Growth
will take place through quality acquisitions, niche development opportunities
and optimization of the company's power portfolio by focusing on low-risk
opportunities in known markets.

Excluding the impact of the settlement with a former counterparty in 2003 and
potential variability in Bruce Power's earnings caused by changes in prices
realized and plant availability, the net earnings outlook for the Power business
in 2004 is expected to be similar to 2003. Earnings opportunities elsewhere in
the business may be affected by factors such as fluctuating market prices for
power and gas, regulatory changes, currency movements, weather, plant
availability and overall stability of the power industry. Please see the
following section "Power - Business Risks" for a complete discussion of these
factors.

TCPL's Power segment is in a strong position to capitalize on opportunities
resulting from industry changes because of its technical expertise and business
models that have proven successful to date. TCPL's growth will continue to focus
on diversifying the asset portfolio by adding plants of varying fuel sources
which are on the low end of the regional dispatch cost curve and/or are
underpinned with strong contractual arrangements.

POWER - BUSINESS RISKS

PLANT AVAILABILITY Maintaining plant availability is critical to the continued
success of the Power business and this risk is mitigated through a commitment to
an operational excellence model that provides low-cost, reliable operating
performance at each of the company's operated power plants. This same commitment
to operational excellence will be applied in 2004 and future years. However,
unexpected plant outages or the duration of outages may require purchases at
market prices to enable TCPL to meet the company's contractual power supply
obligations and/or increase maintenance costs.

FLUCTUATING MARKET PRICES TCPL generally operates in highly competitive,
deregulated markets. Volatility in electricity prices is caused by market
factors such as power plant fuel costs, fluctuating supply and market demand
which are greatly affected by weather, power consumption and plant availability.
TCPL manages these inherent market risks through:

o    long-term purchase and sales contracts for both electricity and plant
     fuels;

o    control of generation output;

o    matching physical plant contracts or PPA supply with customer demand;

o    fee-for-service managed accounts rather than direct commodity exposure; and

o    the company's overall risk management program with respect to general
     market and counterparty risks.

The company's risk management practices are described further in the section on
Risk Management (page M-35). TCPL's largest exposure to sales price fluctuations
is on Bruce Power's uncontracted volumes. See the section "Power - Business
Risks Uncontracted Volumes".

REGULATORY As electricity markets evolve across North America, there is the
potential for regulatory bodies to implement new rules that could negatively
impact TCPL as a generator, marketer and builder of power plants. These may be
in the form of price caps, unfair cost allocations to generators or attempts to
control the wholesale market by encouraging new plant construction. TCPL
continues to monitor regulatory issues and reform as well as participate in and
lead discussions around these topics. TCPL operates in both regulated and
non-regulated power markets.

WEATHER Temperature and weather events may impact power and gas demand and
create price volatility, and may also impact the ability to transmit power to
markets. Seasonal changes in temperature also affect the efficiency and output
capability of natural gas-fired power plants. In addition, the total amount and
seasonality of water flows impacts the output and related earnings from
hydroelectric facilities.

UNCONTRACTED VOLUMES Although TCPL seeks to secure sales under medium- to
long-term contracts, TCPL retains an amount of unsold generation in the short
term in order to provide flexibility in managing the company's portfolio of
owned assets. Bruce Power has a significant amount of its uncontracted
volumes sold into the Ontario wholesale spot market. The sale of this power
in the open market is subject to market

                                      M-26


price volatility which directly impacts income. Bruce Power has sold
approximately 1,560 MW of the expected power output for 2004. Of the remaining
Power segment's portfolio, through the use of PPAs and other marketing
arrangements, TCPL has sold approximately 90 per cent of the expected power
output in 2004 and 70 to 80 per cent for the years 2005 to 2007.

DESCRIPTION OF TCPL'S SIGNIFICANT POWER OPERATIONS

SUNDANCE A&B

The Sundance power plant in Alberta is the largest coal-fired electrical
generating facility in western Canada. Through the Alberta PPA auction in August
2000, TCPL acquired the Sundance A PPA, which increased the company's power
supply by 560 MW for a 17 year period commencing January 2001. In December 2001,

CORPORATE

HIGHLIGHTS

LOWER NET EXPENSES Net expenses in 2003 decreased $11 million or 21 per cent
from 2002.

Interest income and other                                       (23)         (12)          5
                                                         --------------------------------------
Net expenses, after tax                                          41           52          67
-----------------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------------


The Corporate segment reflects net expenses not allocated to specific business
segments, including:

o    INDIRECT FINANCIAL AND PREFERRED EQUITY CHARGES Direct financial charges
     are reported in their respective business segments; these charges are
     primarily associated with the debt and preferred securities related to the
     company's Wholly-Owned Pipelines. Indirect financial charges primarily
     reside in the Corporate segment. These costs are directly impacted by the
     amount of debt TCPL maintains and the degree to which TCPL is impacted by
     fluctuations in interest rates.

o    INTEREST INCOME AND OTHER Interest income is earned on invested cash
     balances. Gains and losses on foreign exchange are included in interest
     income and other.

Net expenses, after tax, in the Corporate segment were $41 million in 2003
compared to $52 million in 2002 and $67 million in 2001. The decrease in 2003
from 2002 is primarily due to the positive impacts of a weaker U.S. dollar
compared to the prior year. These positive impacts substantially offset the
negative impacts of a weaker U.S. dollar reflected in other segments. The
decrease in net expenses in 2002 from 2001 is primarily due to an increase in
interest income and other and the positive impact of lower interest rates offset
by increased Corporate financial charges resulting from the Fair Return
decision.


                                      M-28


The performance of the Canadian dollar relative to the U.S. dollar would either
positively or negatively impact the Corporate segment's results. In 2004, the
performance of the Canadian dollar is not expected to have a significant impact
on TCPL's consolidated financial results since the impact in the Corporate
segment is anticipated to largely offset impacts in the other business segments.

LIQUIDITY AND CAPITAL RESOURCES

HIGHLIGHTS

SUSTAINED GROWTH Total capital expenditures, including acquisitions and assumed
debt, have exceeded $3 billion over the past three years.

DEBT REDUCTION TCPL's repayment of long-term debt, net of new debt issued, and
redemption of debentures and preferred securities has exceeded $1.6 billion over
the past three years.

FUNDS GENERATED FROM OPERATIONS Funds generated from continuing operations were
$1.8 billion for the year ended December 31, 2003 compared to $1.8 billion and
$1.6 billion for 2002 and 2001, respectively. The Gas Transmission business was
the primary source of funds generated from operations for each of the three
years. As a result of rapid growth in the Power business in the last few years,
the Power segment's funds generated from operations increased in 2003 compared
to the two prior years.

The company also reduced long-term debt, junior subordinated debentures and
preferred securities in each of the past three years. TCPL's ability to generate
adequate amounts of cash in the short term and the long term when needed, and to
maintain financial capacity and flexibility to provide for planned growth,
remained as strong at December 31, 2003 as compared to the past few years.

INVESTING ACTIVITIES Capital expenditures, excluding acquisitions and assumed
debt, totalled $391 million in 2003 compared to $599 million and $492 million in
2002 and 2001, respectively. Expenditures in all three years related primarily
to maintenance and capacity capital in TCPL's Gas Transmission business and
construction of new power plants in Canada.

During 2003, TCPL acquired a 31.6 per cent interest in Bruce Power for $409
million, the remaining interests in Foothills previously not held by the company
for $105 million, excluding assumed debt of $154 million, and increased its
interest in Portland, by way of two separate acquisitions, to 61.7 per cent from
33.3 per cent for US$51 million, excluding assumed debt of US$78 million.

During 2002, TCPL acquired the ManChief power plant for $209 million and a
general partnership interest in Northern Border Partners, L.P. $19 million.
During 2001, TCPL acquired the Curtis Palmer Hydroelectric Company L.P. for $438
million and, through a partnership, acquired 50 per cent of the rights and
obligations of the 706 MW Sundance B PPA for $110 million.

TCPL's 2001 investing activities also include proceeds of $1.2 billion from the
sale of non-core assets under the company's divestiture plan.

FINANCING ACTIVITIES In 2003, TCPL used a portion of its cash resources to repay
long-term debt of $744 million, reduce notes payable by $62 million and redeem
all of its outstanding US$160 million, 8.75 per cent Junior Subordinated
Debentures.

In 2003, the company issued $450 million of ten year notes bearing interest at
5.65 per cent and US$350 million of ten year notes bearing interest at 4.00 per
cent. The company repaid debt maturities of $486 million and reduced notes
payable by $46 million in 2002 and repaid debt maturities of $793 million and
redeemed preferred securities of $318 million in 2001. In 2001, TCPL increased
notes payable by $186 million.

Dividends and preferred securities charges amounting to $588 million were paid
in 2003 compared to $546 million and $517 million in 2002 and 2001,
respectively.


                                      M-29


In January 2004, TCPL's Board of Directors declared a dividend for the quarter
ending March 31, 2004 in an aggregate amount equal to the aggregate quarterly
dividend to be paid on April 30, 2004 by TransCanada Corporation on the issued
and outstanding common shares as at the close of business on March 31, 2004.

Net cash used in financing activities includes TCPL's proportionate share of the
net reduction in non-recourse debt of joint ventures amounting to $11 million in
2003 compared to $36 million and $109 million in 2002 and 2001, respectively.

CREDIT ACTIVITIES In 2002, TCPL filed shelf prospectuses, subsequently amended,
that qualify for issuance $2 billion of common shares, preferred shares and/or
debt securities including medium-term notes in Canada and US$1 billion of debt
securities in the U.S., respectively. During 2003, $450 million of medium-term
notes and US$350 million of senior unsecured notes were issued under these
programs.

At December 31, 2003, total credit facilities of $2.2 billion were available to
support the company's commercial paper program and for general corporate
purposes. Of this total, $1.9 billion represents committed credit facilities of
which $1.5 billion represents a syndicated facility established in December
2002. This facility is comprised of a $1.0 billion tranche with a three year
term and a $500 million tranche with a 364 day term with a two year term out
option. Both tranches are extendible on an annual basis and are revolving unless
during a term out period. Both tranches were extended in December 2003, the $1.0
billion tranche to December 2006 and the $500 million tranche to December 2004.
The remaining committed facilities are non-extendible, of which $60 million
expires in June 2004 and $320 million expires in June 2005.

At December 31, 2003, TCPL had used approximately $217 million of its total
lines of credit for letters of credit and to support ongoing commercial
arrangements. If drawn, interest on the lines of credit would be charged at
prime rates of Canadian chartered and U.S. banks or at other negotiated
financial bases.

Credit ratings on TCPL'S senior unsecured debt assigned by Dominion Bond Rating
Service Limited (DBRS), Moody's Investors Service (Moody's) and Standard &
Poor's are currently A, A2 and A-, respectively. DBRS and Moody's both maintain
a `stable' outlook on their ratings and Standard & Poor's maintains a `negative'
outlook on its rating.

CONTRACTUAL OBLIGATIONS

OBLIGATIONS AND COMMITMENTS Total long-term debt at December 31, 2003 was $10.0
billion compared to $9.3 billion at December 31, 2002. TCPL's share of total
non-recourse debt of joint ventures at December 31, 2003 was $0.8 billion
compared to $1.3 billion at the prior year-end. Total notes payable, including
those of joint ventures, at December 31, 2003 were $367 million compared to $297
million at December 31, 2002. The debt and notes payable of joint ventures are
non-recourse to TCPL. The security provided by each joint venture is limited to
the rights and assets of that joint venture and does not extend to the rights
and assets of TCPL, except to the extent of TCPL's investment.


                                      M-30


At December 31, 2003, principal repayments related to long-term debt and the

(1)  The amounts in this table exclude funding contributions to the company's
     pension plans and TCPL's one-third share of project definition phase costs
     in the Mackenzie Gas Pipeline Project.

(2)  Rates are based on known 2004 levels. Beyond 2004, demand rates are subject
     to change. The contractual obligations in the table are based on demand
     volumes only and exclude commodity charges incurred when volumes flow.

(3)  Commodity purchases include fixed and variable components. The variable
     components are estimates and are subject to variability in plant
     production, market prices and regulatory tariffs.

(4)  Amounts are estimates and are subject to variability based on timing of
     construction and project enhancements.

(5)  Includes estimates of certain amounts which are subject to change depending
     on plant-fired hours, the consumer price index, actual plant maintenance
     costs, plant salaries as well as changes in regulated rates for
     transportation.

TCPL expects to make funding contributions to the company's pension plans in the
amount of approximately $80 million during 2004. The expected decrease in
funding in 2004 from the $110 million in 2003 is due to one-time plan design
changes and investment performance above long-term expectations in 2003
partially offset by continued reductions in discount rates used to calculate
plan liabilities.

At December 31, 2003, TCPL held a 35.6 per cent interest in Power LP which is a
publicly-held limited partnership. On June 30, 2017, the partnership will redeem
all units outstanding, not held directly or indirectly by TCPL, at their then
fair market value, being the average of the fair market values assigned thereto
by independent valuators, plus all declared and unpaid distributions of
distributable cash thereon


                                      M-31


(the Redemption Price). TCPL is required to fund the Redemption Price in
accordance with the terms of the Power LP Partnership Agreement.

TCPL has established a $50 million operating line of credit to Power LP,
available on a revolving basis. As at December 31, 2003, the amount borrowed
against this line of credit was $26 million compared to $37 million at December
31, 2002.

At December 31, 2003, TCPL held a 33.4 per cent interest in TC PipeLines, LP
which is a publicly-held limited partnership. On May 28, 2003, TC PipeLines, LP
renewed its US$40 million unsecured two-year revolving credit facility (TCPL
Credit Facility) with a subsidiary of TCPL. At December 31, 2003 and 2002, the
partnership had no amount outstanding under the TCPL Credit Facility.

On June 18, 2003, the Mackenzie Delta gas producers, the APG and TCPL reached an
agreement which governs TCPL's role in the Mackenzie Gas Pipeline Project. The
Project would result in a natural gas pipeline being constructed from Inuvik,
Northwest Territories to the northern border of Alberta, where it would then
connect with the Alberta System. Under the agreement, TCPL has agreed to finance
the APG for its one-third share of project definition phase costs. This share is
estimated to be approximately $90 million over three years. In the year ended
December 31, 2003, TCPL funded $34 million of this loan. The ability to recover
this investment is contingent upon the outcome of the project.

TCPL and its affiliates have long-term natural gas transportation and natural
gas purchase arrangements as well as other purchase obligations, all of which
are or were transacted at market prices and in the normal course of business.

GUARANTEES TCPL had no outstanding guarantees related to the long-term debt of
unrelated third parties at December 31, 2003.

Upon acquisition of Bruce Power, the company, together with Cameco and BPC
Generation Infrastructure Trust, guaranteed on a several pro-rata basis certain
contingent financial obligations of Bruce Power related to operator licenses,
the lease agreement, power sales agreements and contractor services. TCPL's
share of the net exposure under these guarantees at December 31, 2003 was
estimated to be approximately $215 million. The terms of the guarantees range
from 2004 to 2018. The current carrying amount of the liability related to these
guarantees is nil and the fair value is approximately $4 million.

TCPL has guaranteed the equity undertaking of a subsidiary which supports the
payment, under certain conditions, of principal and interest on the US$195
million public debt obligations of TransGas. The company has a 46.5 per cent
interest in TransGas. Under the terms of the agreement, the company severally
with another major multinational company may be required to fund more than their
proportionate share of debt obligations of TransGas in the event that the
minority shareholders fail to contribute. Any payments made by TCPL under this
agreement convert into share capital of TransGas. The potential exposure is
contingent on the impact of any change of law on TransGas' ability to service
the debt. From the issuance of the debt in 1995 to date, there has been no
change in applicable law and thus no exposure to TCPL. The debt matures in 2010.
The company has made no provision related to this guarantee.

CONTINGENCIES The Canadian Alliance of Pipeline Landowners' Associations and two
individual landowners commenced an action under Ontario's Class Proceedings Act,
1992, against TCPL and Enbridge Inc. for damages alleged in 2002 to arise from
the creation of a control zone within 30 metres of the pipeline pursuant to
Section 112 of the NEB Act. The company believes the claim is without merit and
will vigorously defend the action. The company has made no provision for any
potential liability. A liability, if any, would be dealt with through the
regulatory process.

The company and its subsidiaries are subject to various other legal proceedings
and actions arising in the normal course of business. While the final outcome of
such legal proceedings and actions cannot be predicted with certainty, it is the
opinion of management that the resolution of such proceedings and actions will
not have a material impact on the company's consolidated financial position or
results of operations.


                                      M-32


FINANCIAL AND OTHER INSTRUMENTS

The company issues short-term and long-term debt including amounts in foreign
currencies, purchases and sells energy commodities and invests in foreign
operations. These activities result in exposures to interest rates, energy
commodity prices and foreign currency exchange rates. The company utilizes
derivative and other financial instruments to manage its exposure to the risks
that result from these activities. A derivative must be designated and effective
to be accounted for as a hedge. Gains or losses relating to derivatives that are
hedges are deferred and recognized in the same period and in the same financial
statement category as the gains or losses on the corresponding hedged
transactions. The recognition of gains and losses on derivatives used as hedges
for the Alberta System, Canadian Mainline and the Foothills System exposures is
determined through the regulatory process.

The carrying amounts of derivatives, which hedge the price risk of foreign
currency denominated assets and liabilities of self-sustaining foreign
operations are recorded on the balance sheet at their fair value. Gains and
losses on the derivatives, realized and unrealized, are included in the foreign
exchange adjustment account in Shareholders' Equity as a reduction of the
corresponding gains and losses on the translation of the assets and liabilities
of the foreign subsidiaries. Carrying amounts for interest rate swaps represent
the net accrued interest from the last payment date to the reporting date.
Foreign currency transactions hedged by foreign exchange contracts are recorded
at the contract rate. Power, natural gas and heat rate derivatives are recorded
on the balance sheet at their fair value.

The fair values of foreign exchange and interest rate derivatives have been
estimated using year-end market rates. These fair values approximate the amount
that the company would receive or pay if the instruments were closed out at
these dates. The fair values of power, natural gas and heat rate derivatives
have been calculated at year-end using estimated forward prices for the relevant
period.

Notional principal amounts are not recorded in the financial statements because
these amounts are not exchanged by the company and its counterparties and are
not a measure of the company's exposure. Notional amounts are used only as the
basis for calculating payments for certain derivatives.

FOREIGN INVESTMENTS

At December 31, 2003 and 2002, the company had foreign currency denominated
assets and liabilities which created an exposure to changes in exchange rates.
The company uses foreign currency derivatives to hedge this net exposure on an
after-tax basis. The foreign currency derivatives have a floating interest rate
exposure which the company partially hedges by entering into interest rate swaps
and forward rate agreements. The fair values shown in the table below for
foreign exchange risk are offset by translation gains or losses on the net
assets and are recorded in the foreign exchange adjustment account in
Shareholders' Equity.

addition, the company has associated interest rate swaps with notional principal
amounts of $311 million (2002 - $309 million) and US$200 million (2002 - US$350
million). The fair value of these interest rate swaps was $1 million (2002 -

RISK MANAGEMENT

RISK MANAGEMENT OVERVIEW TCPL and its subsidiaries are exposed to market,
financial and counterparty risks in the normal course of their business
activities. The risk management function assists in managing these various
business activities and the risks associated with these activities. A strong
commitment to a risk management culture by management supports this function.
TCPL's primary risk management objective is to protect earnings and cash flow
and ultimately, shareholder value.

The risk management function is guided by the following principles that are
applied to all businesses and risk types:

o    BOARD OVERSIGHT Risk strategies, policies and limits are subject to review
     and approval by TCPL's Board of Directors.

o    INDEPENDENT REVIEW Risk-taking activities are subject to independent
     review, separate from the business lines that initiate the activity.

o    ASSESSMENT Processes are in place to ensure that risks are properly
     assessed at the transaction and counterparty levels.

o    REVIEW AND REPORTING Market positions and exposures, and the
     creditworthiness of counterparties are subject to ongoing review and
     reporting to executive management.

o    ACCOUNTABILITY Business lines are accountable for all risks and the related
     returns for their particular businesses.

o    AUDIT REVIEW Individual risks are subject to internal audit review, with
     independent reporting to the Audit Committee of TCPL's Board of Directors.

The processes within TCPL's risk management function are designed to ensure that
risks are properly identified, quantified, reported and managed. Risk management
strategies, policies and limits are designed to ensure TCPL's risk taking is
consistent with the company's business objectives and risk tolerance. Risks are
managed within limits ultimately established by the company's Board of Directors
and implemented by senior management, monitored by risk management personnel and
audited by internal audit personnel.


                                      M-35


TCPL manages market risk exposures in accordance with the company's corporate
market risk policy and position limits. The company's primary market risks
result from volatility in commodity prices, interest rates and foreign currency
exchange rates.

Senior management reviews these exposures and reports to the Audit Committee of
TCPL's Board of Directors regularly.

MARKET RISK MANAGEMENT In order to manage market risk exposures created by fixed
and variable pricing arrangements at different pricing indices and delivery
points, the company enters into offsetting physical positions and derivative
financial instruments. Market risks are quantified using value-at-risk
methodology and are reviewed weekly by senior management.

FINANCIAL RISK MANAGEMENT TCPL monitors the financial market risk exposures
relating to the company's investments in foreign currency denominated net
assets, regulated and non-regulated long-term debt portfolios and foreign
currency exposure on transactions. The market risk exposures created by these
business activities are managed by establishing offsetting positions or through
the use of derivative financial instruments.

COUNTERPARTY RISK MANAGEMENT Counterparty risk is the financial loss that the
company would experience if the counterparty failed to meet its obligations in
accordance with the terms and conditions of its contracts with the company.
Counterparty risk is mitigated by conducting financial and other assessments to
establish a counterparty's creditworthiness, setting exposure limits and
monitoring exposures against these limits, and, where warranted, obtaining
financial assurances.

The company's counterparty risk management practices and positions are further
described under Credit Risk in Note 12 to the Consolidated Financial Statements.

RISKS AND RISK MANAGEMENT RELATED TO THE KYOTO PROTOCOL The Canadian government
continues to develop climate change policy that will help it meet its commitment
under the Kyoto Protocol. While broad policy mechanisms such as the Domestic
Emissions Trading Program for Large Final Emitters have been identified, program
details are still undefined. Once these details are finalized, TCPL will be
better able to assess the implications on the company.

Over the past several years, TCPL's focus has been, and continues to be, on
developing practical options for reducing greenhouse gas (GHG) emissions from
the company's facilities. This is being achieved through technical and
operational improvements, driven in large part by increased fuel and system
efficiencies and the elimination of methane emissions. TCPL's current position
is that operating initiatives that reduce GHG at the source are more appropriate
than other mechanisms.

DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROLS Pursuant to the
Sarbanes-Oxley Act as adopted by the U.S. Securities and Exchange Commission,
TCPL's management evaluates the effectiveness of the design and operation of the
company's disclosure controls and procedures (disclosure controls). This
evaluation is done under the supervision of, and with the participation of, the
President and Chief Executive Officer and the Chief Financial Officer.

As of the end of the period covered by the annual report on TCPL's Form 40-F,
TCPL's management evaluated the effectiveness of its disclosure controls. Based
on that evaluation, the President and Chief Executive Officer and the Chief
Financial Officer have concluded that TCPL's disclosure controls are effective
in ensuring that material information relating to TCPL is made known to
management on a timely basis, and is included in the annual report on TCPL's
Form 40-F.

To the best of these officers' knowledge and belief, there have been no
significant changes in internal controls or in other factors that could
significantly affect internal controls subsequent to the date on which such
evaluation was completed in connection with the annual report on TCPL's Form
40-F.


                                      M-36


CRITICAL ACCOUNTING POLICY

The company accounts for the impacts of rate regulation in accordance with
generally accepted accounting principles (GAAP) as outlined in Note 1 to the
Consolidated Financial Statements. Three criteria must be met to use these
accounting principles: the rates for regulated services or activities must be
subject to approval by a regulator; the regulated rates must be designed to
recover the cost of providing the services or products; and it must be
reasonable to assume that rates set at levels to recover the cost can be charged
to and will be collected from customers in view of the demand for services or
products and the level of direct and indirect competition. The company's
management believes that all three of these criteria have been met. The most
significant impact from the use of these accounting principles is that in order
to achieve a proper matching of revenues and expenses, the timing of recognition
of certain expenses and revenues may differ from that otherwise expected under
GAAP. The two most significant examples of this relate to the recording of
income taxes on the taxes payable basis and the deferral of foreign exchange
losses as outlined in the Consolidated Financial Statements' Note 13 and Note 7,
respectively.

CRITICAL ACCOUNTING ESTIMATES

Since a determination of many assets, liabilities, revenues and expenses is
dependent upon future events, the preparation of the company's Consolidated
Financial Statements requires the use of estimates and assumptions which have
been made using careful judgment. TCPL's critical accounting estimates are:

DEFERRED AFTER-TAX GAINS AND REMAINING OBLIGATIONS RELATED TO THE GAS MARKETING
BUSINESS TCPL mitigated certain of its remaining exposures associated with the
contingent liabilities related to the divested Gas Marketing operations by
acquiring from a subsidiary of Mirant Corporation (Mirant) certain contracts
under which it still had exposure in 2003, and simultaneously hedging the market
price exposures of these contracts. To determine the exposure to these
contracts, the company uses estimates, including future market prices,
transportation volumes, transportation charges and income taxes. The company
remains contingently liable for certain residual obligations. This obligation is
further described in Discontinued Operations on page M-38.

DEPRECIATION EXPENSE TCPL's plant, property and equipment are depreciated on a
straight-line basis over their estimated useful lives. Depreciation expense for
the year ended December 31, 2003 was $914 million. Depreciation expense impacts
the Gas Transmission and Power segments of the company. In the Gas Transmission
business, depreciation rates are approved by the regulators and recoverable
based on the cost of providing the services or products. A change in the
estimation of the useful lives of the plant, property and equipment in the Gas
Transmission segment would therefore have no material impact on TCPL's net
income but would directly impact funds generated from operations.

ACCOUNTING CHANGES

HEDGING RELATIONSHIPS In November 2001, the Accounting Standards Board (AcSB) of
the Canadian Institute of Chartered Accountants (CICA) issued an Accounting
Guideline "Hedging Relationships" that specifies the circumstances in which
hedge accounting is appropriate, including the identification, documentation,
designation and effectiveness of hedges, and the discontinuance of hedge
accounting. The AcSB amended this guideline in June 2003 to clarify some aspects
and to add an appendix of implementation guidance. The rules under this
guideline are substantially similar to the corresponding requirements under
Statement of Financial Accounting Standards (SFAS) No. 133 which was adopted by
the company for U.S. GAAP purposes, effective January 1, 2001. This accounting
guideline will be effective for the company as of January 1, 2004 on a
prospective basis. TCPL does not expect the new Canadian requirement to have a
significant impact on the company's Consolidated Financial Statements.

DISPOSAL OF LONG-LIVED ASSETS AND DISCONTINUED OPERATIONS In November 2002, the
CICA issued a new Handbook Section "Disposal of Long-Lived Assets and
Discontinued Operations". This section establishes new standards for the
recognition, measurement, presentation and disclosure of the disposal of
long-lived assets. It also establishes standards for the presentation and
disclosure of discontinued operations, whether


                                      M-37


or not they include long-lived assets. This section was effective for the
company on a prospective basis after May 1, 2003 and did not result in
restatement of income for prior periods.

IMPAIRMENT OF LONG-LIVED ASSETS In November 2002, the CICA issued a new Handbook
Section "Impairment of Long-Lived Assets". This section establishes new
standards for the recognition, measurement and disclosure of the impairment of
long-lived assets and establishes new write-down provisions. This section will
be effective for the company as of January 1, 2004 and is not expected to have a
significant impact on the company's Consolidated Financial Statements.

ASSET RETIREMENT OBLIGATIONS In January 2003, the CICA issued a new Handbook
Section "Asset Retirement Obligations". The new section focuses on the
recognition and measurement of liabilities for obligations associated with the
retirement of property, plant and equipment when those obligations result from
the acquisition, construction, development or normal operation of the assets.
The section requires that the fair value of a liability for an asset retirement
obligation be recognized in the period in which it is incurred if a reasonable
estimate of fair value can be made. The fair value is added to the carrying
amount of the associated asset. The liability is accreted at the end of each
period through charges to operating expenses. This standard is substantially
similar to the corresponding requirements under SFAS No. 143 which was adopted
by the company for U.S. GAAP purposes, effective January 1, 2003. This section
will be effective for TCPL as of January 1, 2004. The impact of this standard
has been outlined in Note 19 of the Consolidated Financial Statements.

CONSOLIDATION OF VARIABLE INTEREST ENTITIES In June 2003, the AcSB of the CICA
issued a new Accounting Guideline "Consolidation of Variable Interest Entities"
which requires enterprises to identify variable interest entities in which they
have an interest, determine whether they are the primary beneficiary of such
entities and, if so, to consolidate them. For TCPL, the guideline's disclosure
requirements are effective as of January 1, 2004 and the consolidation
requirements are effective as of January 1, 2005. Adopting the provisions of
this guideline is not expected to impact the company's Consolidated Financial
Statements.

GENERALLY ACCEPTED ACCOUNTING PRINCIPLES In July 2003, the CICA issued a new
Handbook Section "Generally Accepted Accounting Principles" which establishes
standards for financial reporting in accordance with GAAP. It defines primary
sources of GAAP and requires that an entity apply every relevant primary source.
This section will be effective for the company as of January 1, 2004 and will
require the recognition of additional regulated assets and liabilities but is
not expected to have a significant impact on the company's net income.

GENERAL STANDARDS OF FINANCIAL STATEMENT PRESENTATION In July 2003, the CICA
issued a new Handbook Section "General Standards of Financial Statement
Presentation" which clarifies what constitutes "fair presentation in accordance
with GAAP". This section will be effective for the company as of January 1, 2004
and is not expected to have an impact on the company's Consolidated Financial
Statements.

DISCONTINUED OPERATIONS

FINANCIAL REVIEW

TCPL's Board of Directors approved a plan to dispose of the company's
International, Canadian Midstream, and certain other businesses (December Plan)
and the disposal of the Gas Marketing business in December 1999 and July 2001,
respectively. The company's disposals under both plans were substantially
completed at December 31, 2001.

The company's investments in Gasoducto del Pacifico, INNERGY Holdings S.A. and
P.T. Paiton Energy Company approved for disposal under the December Plan will be
accounted for as part of continuing operations as of December 31, 2003 due to
the length of time it has taken the company to dispose of these assets. It is
the intention of the company to continue with its plan to dispose of these
investments.


                                      M-38


In 2003, the company reviewed the provision for loss on discontinued operations
and the deferred gain, taking into consideration the impacts of Mirant filing
for bankruptcy protection and the mitigation of certain contingent liabilities
referred to below. As a result of this review, TCPL recognized in income in 2003
$50 million of the original approximately $100 million after-tax deferred gain.
Any further adjustments to the estimate of the net loss on disposal and the
deferred gain will be recognized as a gain or loss from discontinued operations
in the period that such changes are determined.

The company's net income/(loss) from discontinued operations in 2002 was nil as
the existing provision for loss on discontinued operations was reviewed by the
company's management and determined to be appropriate. The company recorded a
net loss from discontinued operations in 2001 of $67 million. This amount
includes a net loss of $90 million based on management's estimates of proceeds
and disposal costs and net earnings of $3 million prior to plan approval,
related to the Gas Marketing business. Also included in 2001 is a positive $20
million after-tax adjustment to the December Plan.

TCPL remains contingently liable pursuant to guarantees and obligations under
certain contracts that relate to the divested Gas Marketing business. In
accordance with the terms of these contracts and in the normal course of
business, the company expects the underlying volumes related to the contracts to
decrease over time. The contingent liability under these obligations is
contingent on certain future events, the occurrence and the amount of which is
not determinable. The purchasers of the Gas Marketing business have agreed to
indemnify TCPL in the event the company is called upon to perform under the
obligations.

                              REPORT OF MANAGEMENT

The consolidated financial statements included in this Annual Report are the
responsibility of Management and have been approved by the Board of Directors of
the Company. These consolidated financial statements have been prepared by
Management in accordance with generally accepted accounting principles (GAAP) in
Canada and include amounts that are based on estimates and judgments. Financial
information contained elsewhere in this Annual Report is consistent with the
consolidated financial statements.

Management has prepared Management's Discussion and Analysis (MD&A) which is
based on the Company's financial results prepared in accordance with Canadian
GAAP. It compares the Company's financial performance in 2003 to 2002 and should
be read in conjunction with the consolidated financial statements and
accompanying notes. In addition, significant changes between 2002 and 2001 are
highlighted. Note 19 to the consolidated financial statements describes the
impact on the consolidated financial statements of significant differences
between Canadian and United States GAAP.

Management has developed and maintains a system of internal accounting controls,
including a program of internal audits. Management believes that these controls
provide reasonable assurance that financial records are reliable and form a
proper basis for preparation of financial statements. The internal accounting
control process includes Management's communication to employees of policies
which govern ethical business conduct.

The Board of Directors has appointed an Audit Committee consisting of unrelated,
non-management directors which meets at least five times during the year with
Management and independently with each of the internal and external auditors and
as a group to review any significant accounting, internal control and auditing
matters. The Audit Committee reviews the consolidated financial statements with
Management and the external auditors before the consolidated financial
statements are submitted to the Board of Directors for approval. The internal
and external auditors have free access to the Audit Committee without obtaining
prior Management approval.

With respect to the external auditors, KPMG LLP, the Audit Committee approves
the terms of engagement and reviews the annual audit plan, the Auditors' Report
and results of the audit. It also recommends to the Board of Directors the firm
of external auditors to be appointed by the shareholder.

The independent external auditors, KPMG LLP, have been appointed by the
shareholder to express an opinion as to whether the consolidated financial
statements present fairly, in all material respects, the Company's financial
position, results of operations and cash flows in accordance with Canadian
generally accepted accounting principles. The report of KPMG LLP on page 7
outlines the scope of their examination and their opinion on the consolidated
financial statements.

AUDITORS' REPORT

TO THE SHAREHOLDER OF TRANSCANADA PIPELINES LIMITED

We have audited the consolidated balance sheets of TransCanada PipeLines Limited
as at December 31, 2003 and 2002 and the consolidated statements of income,
retained earnings and cash flows for each of the years in the three-year period
ended December 31, 2003. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with Canadian generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of the Company as at December 31, 2003
and 2002 and the results of its operations and its cash flows for each of the

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

TransCanada PipeLines Limited (the Company or TCPL) is a leading North American
energy company. TCPL operates in two business segments, Gas Transmission and
Power, each of which offers different products and services.

GAS TRANSMISSION

The Gas Transmission segment owns and operates a natural gas transmission system
in Alberta (the Alberta System), a natural gas transmission system extending
from the Alberta border east into Quebec (the Canadian Mainline), a natural gas
transmission system extending from the Alberta border west into southeastern
British Columbia (the BC System), and a natural gas transmission system
extending from central Alberta to the British Columbia, Saskatchewan and the
United States borders (the Foothills System). Gas Transmission also holds the
Company's investments in other natural gas pipelines in Canada and the U.S. In
addition, Gas Transmission investigates and develops new natural gas
transmission, storage and liquefied natural gas regasification facilities in
Canada and the U.S.

POWER

The Power segment builds, owns and operates electrical power generation plants,
and markets electricity. Power also holds the Company's investments in other
electrical power generation plants. This business operates in Canada and the
U.S.

NOTE 1 ACCOUNTING POLICIES

The consolidated financial statements of the Company have been prepared by
Management in accordance with Canadian generally accepted accounting principles
(Canadian GAAP). These accounting principles are different in some respects from
United States generally accepted accounting principles (U.S. GAAP) and the
significant differences are described in Note 19. Amounts are stated in Canadian
dollars unless otherwise indicated. Certain comparative figures have been
reclassified to conform with the current year's presentation.

Since a determination of many assets, liabilities, revenues and expenses is
dependent upon future events, the preparation of these consolidated financial
statements requires the use of estimates and assumptions which have been made
using careful judgment. In the opinion of Management, these consolidated
financial statements have been properly prepared within reasonable limits of
materiality and within the framework of the significant accounting policies
summarized below.

BASIS OF PRESENTATION

Pursuant to a plan of arrangement, effective May 15, 2003, common shares of TCPL
were exchanged on a one-to-one basis for common shares of TransCanada
Corporation (TransCanada). As a result, TCPL became a wholly-owned subsidiary of
TransCanada. The consolidated financial statements for the year ended December
31, 2003 include the accounts of TCPL, the consolidated accounts of all
subsidiaries, and TCPL's proportionate share of the accounts of the Company's
joint venture investments.


                                      F-8


On August 15, 2003, the Company acquired the remaining interests in Foothills
Pipe Lines Ltd. and its subsidiaries (Foothills) previously not held by TCPL,
and Foothills was consolidated subsequent to that date. On December 3, 2003,
TCPL increased its ownership interest in Portland Natural Gas Transmission
System Partnership (Portland) from 43.4 per cent to 61.7 per cent. Subsequent
to the acquisition, Portland was fully consolidated in the Company's
financial statements with 38.3 per cent reflected in non-controlling
interests.

TCPL uses the equity method of accounting for investments over which the Company
is able to exercise significant influence.

REGULATION

The Alberta System is regulated by the Alberta Energy and Utilities Board (EUB),
and the Canadian Mainline, the BC System, the Foothills System, and Trans Quebec
& Maritimes Pipeline Inc. (Trans Quebec & Maritimes) are subject to the
authority of the National Energy Board (NEB). All Canadian natural gas
transmission operations are regulated with respect to the determination of
tolls, construction and operations. In December 2002, the NEB approved TCPL's
application for the Canadian Mainline to charge interim tolls for transportation
service, effective January 1, 2003. In August 2003, subsequent to the NEB's
decision on the 2003 Tolls and Tariff Application, it approved interim tolls for
the period September 1, 2003 to December 31, 2003. The NEB determined that tolls
will remain interim pending a decision from the Federal Court of Appeal on
TransCanada's Fair Return Review and Variance Application. Any adjustments to
the interim tolls will be recorded in accordance with the final NEB decision.
The natural gas pipelines in the United States and certain power plants are also
subject to the authority of regulatory bodies. In order to achieve a proper
matching of revenues and expenses, the timing of recognition of certain revenues
and expenses in these businesses may differ from that otherwise expected under
generally accepted accounting principles.

CASH AND SHORT-TERM INVESTMENTS

The Company's short-term investments with original maturities of three months or
less are considered to be cash equivalents and are recorded at cost, which
approximates market value.

INVENTORIES

Inventories are carried at the lower of average cost or net realizable value and
primarily consist of materials and supplies including spare parts, and storage
gas.

PLANT, PROPERTY AND EQUIPMENT

GAS TRANSMISSION

Plant, property and equipment of natural gas transmission operations are carried
at cost. Depreciation is calculated on the straight-line basis. Pipeline and
compression equipment are depreciated at annual rates ranging from two to five
per cent and metering and other plant are depreciated at various rates. Removal
and site restoration costs are not determinable and will be recorded when
reasonably estimable. An allowance for funds used during construction, using the
rate of return on rate base approved by the regulators, is capitalized and
included in the cost of gas transmission plant.


                                      F-9


POWER

Plant, property and equipment in the Power business are recorded at cost and
depreciated on the straight-line basis over estimated service lives at average
annual rates ranging from two to five per cent. Interest is capitalized on
significant capital projects.

CORPORATE

Corporate plant, property and equipment are recorded at cost and depreciated on
a straight-line basis over estimated useful lives at average annual rates
ranging from three to twenty per cent.

POWER PURCHASE ARRANGEMENTS

The initial payments for power purchase arrangements (PPAs) are deferred and are
being amortized over the terms of the contracts, from the dates of acquisition,
which range from nine to 27 years. PPAs are long-term contracts to purchase
power on a predetermined basis.

INCOME TAXES

As prescribed by the regulators, the taxes payable method of accounting for
income taxes is used for tollmaking purposes for Canadian natural gas
transmission operations. Under the taxes payable method, it is not necessary to
provide for future income taxes. This method is also used for accounting
purposes, since there is reasonable expectation that future taxes payable will
be included in future costs of service and recorded in revenues at that time.
The liability method of accounting for income taxes is used for the remainder of
the Company's operations. Under this method, future tax assets and liabilities
are recognized for the future tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and
liabilities and their respective tax bases. Future income tax assets and
liabilities are measured using enacted or substantively enacted tax rates
expected to apply to taxable income in the years in which temporary differences
are expected to be recovered or settled. Changes to these balances are
recognized in income in the period in which they occur.

Canadian income taxes are not provided on the unremitted earnings of foreign
investments which are considered to be indefinitely reinvested in foreign
operations.

FOREIGN CURRENCY TRANSLATION

The Company's foreign operations are self-sustaining and are translated into
Canadian dollars using the current rate method. Translation adjustments are
reflected in the foreign exchange adjustment in Shareholders' Equity.

Exchange gains or losses on the principal amounts of foreign currency debt,
junior subordinated debentures and preferred securities related to the Alberta
System and the Canadian Mainline are deferred until they are recovered in tolls.


                                      F-10


DERIVATIVE FINANCIAL INSTRUMENTS

The Company utilizes derivative and other financial instruments to manage its
exposure to changes in foreign currency exchange rates, interest rates and
energy commodity prices. Gains or losses relating to derivatives that are hedges
are deferred and recognized in the same period and in the same financial
statement category as the gains or losses on the corresponding hedged
transactions. The recognition of gains and losses on derivatives used as hedges
for Alberta System, Canadian Mainline and the Foothills System exposures is
determined through the regulatory process.

A derivative must be designated and effective to be accounted for as a hedge.
For cash flow hedges, effectiveness is achieved if the changes in the cash flows
of the derivative substantially offset the changes in the cash flows of the
hedged position and the timing of the cash flows is similar. Effectiveness for
fair value hedges is achieved if the fair value of the derivative substantially
offsets changes in the fair value attributable to the hedged item. In the event
that a derivative does not meet the designation or effectiveness criterion, the
gain or loss on the derivative is recognized in income. If a derivative that
qualifies as a hedge is settled early, the gain or loss at settlement is
deferred and recognized when the gain or loss on the hedged transaction is
recognized. Premiums paid or received with respect to derivatives that are
hedges are deferred and amortized to income over the term of the hedge.

EMPLOYEE BENEFIT PLANS

The Company sponsors defined benefit pension plans. The cost of defined benefit
pensions and other post-employment benefits earned by employees is actuarially
determined using the projected benefit method pro-rated on service and
Management's best estimate of expected plan investment performance, salary
escalation, retirement ages of employees and expected health care costs. Pension
plan assets are measured at fair value. The expected return on pension plan
assets is determined using market-related values. Adjustments arising from plan
amendments are amortized on a straight-line basis over the average remaining
service period of employees active at the date of amendment. The excess of the
net actuarial gain or loss over 10 per cent of the greater of the benefit
obligation and the fair value of plan assets is amortized over the average
remaining service period of the active employees. The Company previously
sponsored two additional plans, a defined contribution plan and a combination of
the defined benefit and defined contribution plans, which were effectively
terminated at December 31, 2002.

The amount allocated to the investment in Bruce Power includes a purchase price
allocation of $301 million to the capital lease of the Bruce Power plant which
will be amortized on a straight-line basis over the lease term which extends to
2018, resulting in an annual amortization expense of $19 million. The amount
allocated to the power sales agreements will be amortized to income over the
remaining term of the underlying sales contracts. The amortization of the fair
value allocated to these contracts is: 2003 - $38 million; 2004 - $37 million;
2005 - $25 million; 2006 - $29 million; and 2007 - $2 million. The amount
allocated to the pension liability will be amortized to income over the 11 year
expected average remaining service life of Bruce Power employees, resulting in
an annual amortization of $3 million.

(1)  Amounts outstanding represent TCPL's proportionate share and are stated in
     millions of Canadian dollars; amounts denominated in U.S. dollars are
     stated in millions.

(2)  Weighted average interest rates are stated as at the respective outstanding
     dates. At December 31, 2003, the effective weighted average interest rate
     on the bank loan of Iroquois resulting from a swap agreement is 4.5 per
     cent (2002 - 4.8 per cent).

(3)  On August 15, 2003, the Company acquired the remaining interests in
     Foothills previously not held by TCPL, and Foothills was consolidated in
     the Company's financial statements subsequent to that date.

The debt of joint ventures is non-recourse to TCPL. The security provided by
each joint venture is limited to the rights and assets of that joint venture and
does not extend to the rights and assets of TCPL, except to the extent of TCPL's
investment.

The Company's proportionate share of principal repayments resulting from
maturities and sinking fund obligations of the non-recourse joint venture debt
approximates: 2004 - $19 million; 2005 - $69 million; 2006 - $55 million; 2007 -
$19 million; and 2008 - $19 million.

The Company's proportionate share of the interest payments of joint ventures was
$67 million for the year ended December 31, 2003 (2002 - $88 million; 2001 -
$100 million).

PREFERRED SECURITIES

The US$460 million 8.25 per cent Preferred Securities are redeemable by the
Company at par at any time. The Company may elect to defer interest payments on
the Preferred Securities and settle the deferred interest in either cash or
common shares.

Since the deferred interest may be settled through the issuance of common shares
at the option of the Company, the Preferred Securities are classified into their
respective debt and equity components. The equity component of the Preferred
Securities is $672 million at December 31, 2003 (2002 - $674 million).

JUNIOR SUBORDINATED DEBENTURES

On July 3, 2003, the Company redeemed the US$160 million, 8.75 per cent Junior
Subordinated Debentures. Holders of these debentures received US$25.0122 per
US$25.00 of the principal amount, which included accrued and unpaid interest to
the redemption date, without premium or penalty.

par value.


                                      F-22


RESTRICTION ON DIVIDENDS

Certain terms of the Company's preferred shares, preferred securities, and debt
instruments could restrict the Company's ability to declare dividends on
preferred and common shares. At December 31, 2003, such terms did not restrict
or alter the Company's ability to declare dividends.

NOTE 12 RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

The Company issues short-term and long-term debt including amounts in foreign
currencies, purchases and sells energy commodities and invests in foreign
operations. These activities result in exposures to interest rates, energy
commodity prices and foreign currency exchange rates. The Company uses
derivatives to manage the risk that results from these activities.

CARRYING VALUES OF DERIVATIVES

The carrying amounts of derivatives, which hedge the price risk of foreign
currency denominated assets and liabilities of self-sustaining foreign
operations are recorded on the balance sheet at their fair value. Gains and
losses on the derivatives, realized and unrealized, are included in the foreign
exchange adjustment account in Shareholders' Equity as a reduction of the
corresponding gains and losses on the translation of the assets and liabilities
of the foreign subsidiaries. Carrying amounts for interest rate swaps represent
the net accrued interest from the last payment date to the reporting date.
Foreign currency transactions hedged by foreign exchange contracts are recorded
at the contract rate. Power, natural gas and heat rate derivatives are recorded
on the balance sheet at their fair value. The carrying amounts shown in the
tables that follow are recorded in the Consolidated Balance Sheet.

FAIR VALUES OF FINANCIAL INSTRUMENTS

Cash and short-term investments and notes payable are valued at their carrying
amounts due to the short period to maturity. The fair values of long-term debt,
non-recourse long-term debt of joint ventures and junior subordinated debentures
are determined using market prices for the same or similar issues.

The fair values of foreign exchange and interest rate derivatives have been
estimated using year-end market rates. These fair values approximate the amount
that the Company would receive or pay if the instruments were closed out at
these dates.

CREDIT RISK

Credit risk results from the possibility that a counterparty to a derivative in
which the Company has an unrealized gain fails to perform according to the terms
of the contract. Credit exposure is minimized through the use of established
credit management techniques, including formal assessment processes, contractual
and collateral requirements and credit exposure limits. At December 31, 2003,
for foreign currency and interest rate derivatives, total credit risk and the
largest credit exposure to a single counterparty were $127 million and $29
million, respectively. At December 31, 2003, for power, natural gas and heat
rate derivatives, total credit risk and the largest credit exposure to a single
counterparty were $67 million and $61 million, respectively.

NOTIONAL AMOUNTS

Notional principal amounts are not recorded in the financial statements because
these amounts are not exchanged by the Company and its counterparties and are
not a measure of the Company's exposure. Notional amounts are used only as the
basis for calculating payments for certain derivatives.


                                      F-23


FOREIGN INVESTMENTS

At December 31, 2003 and 2002, the Company had foreign currency denominated
assets and liabilities which created an exposure to changes in exchange rates.
The Company uses foreign currency derivatives to hedge this net exposure on an
after-tax basis. The foreign currency derivatives have a floating interest rate
exposure which the Company partially hedges by entering into interest rate swaps
and forward rate agreements. The Company's portfolio of foreign investment
derivatives is comprised of contracts for periods up to four years. The fair
values shown in the table below for foreign exchange risk are offset by
translation gains or losses on the net assets and are recorded in the foreign
exchange adjustment account in Shareholders' Equity.

addition, the Company has associated interest rate swaps with notional principal
amounts of $311 million (2002 - $309 million) and US$200 million (2002 - US$350

ENERGY PRICE RISK MANAGEMENT

The Company executes power, natural gas and heat rate derivatives for overall
management of its asset portfolio. The Company's portfolio of power, natural gas
and heat rate derivatives is primarily comprised of swap, option and forward
contracts for periods of up to 13 years, with fixed and floating price
commitments. Heat rate contracts are contracts for the sale or purchase of power
that are priced based on a natural gas index. The fair values of power, natural
gas and heat rate derivatives have been calculated at year-end using estimated
forward prices for the relevant period. The fair values and notional volumes of
the swap, option, forward and heat rate contracts are shown in the tables below.

denominated in different currencies, the Company may enter into forward foreign
exchange contracts and foreign exchange options which establish the foreign
exchange rate for the cash flows from the related purchase and sale
transactions.

The Company follows the taxes payable method of accounting for income taxes
related to the operations of the Canadian natural gas transmission operations.
If the liability method of accounting had been used, additional future income
tax liabilities in the amount of $1,758 million at December 31, 2003 (2002 -
$1,702 million) would have been recorded and would be recoverable from future
revenues.

UNREMITTED EARNINGS OF FOREIGN INVESTMENTS

Income taxes have not been provided on the unremitted earnings of foreign
investments which the Company intends to indefinitely reinvest in foreign
operations. If provision for these taxes had been made, future income tax
liabilities would increase by approximately $54 million at December 31, 2003
(2002 - $60 million).

INCOME TAX PAYMENTS

Income tax payments of $220 million were made during the year ended December 31,
2003 (2002 - $257 million; 2001 - $292 million).

Total credit facilities of $2.2 billion at December 31, 2003, were available to
support the Company's commercial paper progams and for general corporate
purposes. Of this total, $1.9 billion represents committed credit facilities of
which $1.5 billion represents a syndicated facility established in December
2002. This facility is comprised of a $1.0 billion tranche with a three year
term and a $500 million tranche with a 364 day term with a two year term out
option. Both tranches are extendible on an annual basis and are revolving unless
during a term out period. Both tranches were extended in December 2003, the $1.0
billion tranche to December 2006 and the $500 million tranche to December 2004.
The remaining committed facilities are non extendible, $60 million expires in
June 2004 and $320 million expires in June 2005.

At December 31, 2003, the Company had used approximately $217 million of its
total lines of credit for letters of credit and to support its ongoing
commercial arrangements. If drawn, interest on the lines of credit would be
charged at prime rates of Canadian chartered and U.S. banks and at other
negotiated financial bases. The cost to maintain the unused portion of the lines
of credit is approximately $2 million for the year ended December 31, 2003 (2002
- $1 million).

NOTE 15 EMPLOYEE FUTURE BENEFITS

The Company sponsors defined benefit pension plans (DB Plans) that cover
substantially all employees and sponsored a defined contribution pension plan
(DC Plan) which was effectively terminated at December 31, 2002. The DB Plans
are based on years of service and highest average earnings over three
consecutive years of employment. Under the DC Plan, Company contributions were
based on the participating employees' pensionable earnings. As a result of the
termination of the DC Plan, members of this plan were awarded retroactive
service credit under the DB Plans for all years of service. In exchange for past
service credit, members surrendered the accumulated assets in their DC Plan
accounts to the DB Plans as at December 31, 2002. This plan amendment resulted
in unamortized past service costs of $44 million. Past service costs are
amortized over the expected average remaining service life of employees, which
is an average of 12 years.

The Company also provides its employees with other post-employment benefits
other than pensions, including special termination benefits and defined life
insurance and medical benefits beyond those provided by government-sponsored
plans. Effective January 1, 2003, the Company combined its previously existing
other post-employment benefit plans into one plan for active employees and
provided existing retirees the option of adopting the provisions of the new
plan. This plan amendment resulted in unamortized past service costs of $7
million. Past service costs are amortized over the expected average remaining
life expectancy of former employees, which is approximately 19 years.

The expense for the DC Plan is nil for the year ended December 31, 2003 (2002 -
$6 million; 2001 - $7 million). In 2003, the Company also expensed $1 million
(2002 - nil; 2001 - nil) related to retirement savings plans for its U.S.
employees.

Information about the Company's DB Plans measured and valued at December 31 is
as follows.

Expected long-term rate of return on plan assets        7.25%        7.52%        7.10%
Rate of compensation increase                           3.75%        3.50%        3.50%


The overall expected long-term rate of return on plan assets is based on
historical and projected rates of return for both the portfolio in aggregate and
for each asset class in the portfolio. Assumed projected rates of return are
selected after analyzing historical experience and future expectations of the
level and volatility of returns. Asset class benchmark returns, asset mix and
anticipated benefit payments from plan assets are also considered in the
determination of the overall expected rate of return.

For measurement purposes, a 7.5 per cent annual rate of increase in the per
capita cost of covered health care benefits was assumed for 2004. The rate was
assumed to decrease gradually to 5.0 per cent for 2009 and remain at that level
thereafter. A one percentage point increase or decrease in assumed health care
cost trend rates would have the following effects.

within an acceptable risk tolerance. Pension assets are invested in a
diversified manner with consideration given to the demographics of the plan
participants.

The operating lease agreements expire at various dates through 2011, with an
option to renew certain lease agreements for five years.

At December 31, 2003, TCPL held a 35.6 per cent interest in TransCanada Power,
L.P. which is a publicly-held limited partnership. On June 30, 2017, the
partnership will redeem all units outstanding, not held directly or indirectly
by TCPL, at their then fair market value, being the average of the fair market
values assigned thereto by independent valuators, plus all declared and unpaid
distributions of distributable cash thereon (the Redemption Price). TCPL is
required to fund the Redemption Price in accordance with the terms of the Power
LP Partnership agreement.

On June 18, 2003, the Mackenzie Delta gas producers, the Aboriginal Pipeline
Group (APG) and TransCanada reached an agreement which governs TCPL's role in
the Mackenzie Gas Pipeline Project. The project would result in a natural gas
pipeline being constructed from Inuvik, Northwest Territories to the northern
border of Alberta, where it would then connect with the Alberta System. Under
the agreement, TCPL has agreed to finance the APG for its one-third share of
project definition phase costs. This share is estimated to be approximately $90
million over three years. In the year ended December 31, 2003, TransCanada
funded $34 million of this loan which is included in Other Assets. The ability
to recover this investment is contingent upon the outcome of the project.

CONTINGENCIES

The Canadian Alliance of Pipeline Landowners' Associations and two individual
landowners have commenced an action under Ontario's Class Proceedings Act, 1992,
against TCPL and Enbridge Inc. for damages alleged to arise from the creation of
a control zone within 30 metres of the pipeline pursuant to section 112 of the
NEB Act. The Company believes the claim is without merit and will vigorously
defend the action. The Company has made no provision for any potential
liability. A liability, if any, would be dealt with through the regulatory
process.

The Company and its subsidiaries are subject to various other legal proceedings
and actions arising in the normal course of business. While the final outcome of
such legal proceedings and actions cannot be predicted with certainty, it is the
opinion of Management that the resolution of such proceedings and actions will
not have a material impact on the Company's consolidated financial position or
results of operations.

GUARANTEES

Upon acquisition of Bruce Power, the Company, together with Cameco Corporation
and BPC Generation Infrastructure Trust, guaranteed on a several pro-rata basis
certain contingent financial obligations of Bruce Power related to operator
licenses, the lease agreement, power sales agreements and contractor services.
TCPL's share of the net exposure under these guarantees at December 31, 2003 was
estimated to be approximately $215 million. The terms of the guarantees range
from 2004 to 2018. The current carrying amount of the liability related to these
guarantees is nil and the fair value is approximately $4 million.

TCPL has guaranteed the equity undertaking of a subsidiary which supports the
payment, under certain conditions, of principal and interest on the US$195
million public debt obligations of TransGas de Occidente, S.A. (TransGas). The
Company has a 46.5 per cent interest in TransGas. Under the terms of the
agreement, the Company severally with another major multinational company may be
required to fund more than their proportionate share of debt obligations of
TransGas in the event that the minority shareholders fail to contribute. Any
payments made by TCPL under this agreement convert into share capital of
TransGas. The potential exposure is contingent on the impact of any change of
law on TransGas' ability to service the debt. From the issuance of the debt in
1995 to date, there has been no change in applicable law and thus no exposure to
TCPL. The debt matures in 2010. The Company has made no provision related to
this guarantee.

NOTE 18 DISCONTINUED OPERATIONS

The Board of Directors approved plans to dispose of the Company's International,
Canadian Midstream, and certain other businesses (December Plan) and the Gas
Marketing business in December 1999 and July 2001, respectively. The Company's
disposals under both plans were substantially completed at December 31, 2001.

TCPL's investments in Gasoducto del Pacifico, INNERGY Holdings S.A. and P.T.
Paiton Energy Company approved for disposal under the December Plan will be
accounted for as part of continuing operations as of December 31, 2003, due to
the length of time it has taken the Company to dispose of these assets. It is
the intention of the Company to continue with its plan to dispose of these
investments.

The Company mitigated certain of its remaining exposures associated with the
contingent liabilities related to the divested Gas Marketing operations by
acquiring from a subsidiary of Mirant Corporation (Mirant) certain contracts
under which it still had exposure in 2003, and simultaneously hedging the market
price exposures of these contracts. The Company remains contingently liable for
certain residual obligations. In 2003, $50 million of the original approximately
$100 million after-tax deferred gain was recognized in income. The remaining
after-tax deferred gain is included in Deferred Amounts.

At December 31, 2003, TCPL reviewed the provision for loss on discontinued
operations and the deferred gain and concluded that the remaining provision was
adequate and the deferral of the remaining approximately $50 million of
after-tax deferred gain related to the Gas Marketing business was appropriate.

Revenues from discontinued operations for the year ended December 31, 2003 were
$2 million (2002 - $36 million; 2001 - $12,895 million). Net income/(loss) from
discontinued operations for the year ended December 31, 2003 was $50 million,
net of $29 million income taxes (2002 - nil; 2001 - $(67) million, net of $(33)
million income taxes). The provision for loss on discontinued operations at
December 31, 2003 was $41 million (2002 - $83 million). The provision for loss
on discontinued operations is included in Accounts Payable.

                                      F-34


(1)  In accordance with U.S. GAAP, the Condensed Statement of Consolidated
     Income and Condensed Balance Sheet are prepared using the equity method of
     accounting for joint ventures. Excluding the impact of other U.S. GAAP
     adjustments, the use of the proportionate consolidation method of
     accounting for joint ventures, as required under Canadian GAAP, results in
     the same net income and Shareholders' Equity.

(2)  In 2002, for U.S. GAAP purposes, TCPL adopted the transitional provisions
     of FASB Emerging Issues Task Force (EITF) 02-3, "Accounting for Contracts
     Involved in Energy Trading and Risk Management Activities" whereby the
     Company was netting all revenues and expenses related to derivative energy
     trading contracts. The accounting change was applied retroactively with
     reclassification of prior periods. Prior to adoption of EITF 02-3, energy
     trading contracts were measured at fair value determined as at the balance
     sheet date. Effective January 1, 2003, the Company fully adopted EITF 02-3.
     This accounting change was effected through a cumulative adjustment of
     $(13) million, after tax, in the current year's income with no restatement
     of prior periods. Substantially all of the energy trading contracts are
     accounted for as hedges under Canadian GAAP. Subsequent to October 1, 2003,
     the energy trading contracts that qualified as hedges were accounted for as
     hedges under the provisions of Statement of Financial Accounting Standards
     (SFAS) No. 133. All gains or losses on the contracts that did not qualify
     as hedges, and the amounts of any ineffectiveness on the hedging contracts,
     are included in income each period. Substantially all of the amounts
     recorded in 2003 as differences between U.S. and Canadian GAAP relate to
     gains and losses on contracts that were not accounted for as hedges.

(3)  (a) Under Canadian GAAP, pre-operating costs incurred during the
     commissioning phase of a new project are deferred until commercial
     production levels are achieved. After such time, those costs are amortized
     over the estimated life of the project. Under U.S. GAAP, such costs are
     expensed as incurred. Certain start-up costs incurred by Bruce Power are
     required to be expensed under U.S. GAAP.

     (b) Under both Canadian GAAP and U.S. GAAP, interest is capitalized on
     expenditures relating to construction of development projects actively
     being prepared for their intended use. In Bruce Power, under U.S. GAAP, the
     carrying value of development projects against which interest is
     capitalized is lower due to the expensing of pre-operating costs.

(4)  In 2001, the Company adopted the provisions of SFAS No. 133 "Accounting for
     Derivatives and Hedging Activities". SFAS No. 133 requires that all
     derivatives be recognized as assets and liabilities on the balance sheet
     and measured at fair value.

     For derivatives designated as fair value hedges, changes in the fair value
     are recognized in earnings together with an equal or lesser amount of
     changes in the fair value of the hedged item attributable to the hedged
     risk. For derivatives designated as cash flow hedges, changes in the fair
     value of the derivative that are effective in offsetting the hedged risk
     are recognized in other comprehensive income until the hedged item is
     recognized in earnings. Any ineffective portion of the change in fair value
     is recognized in earnings each period.

     On initial adoption of SFAS No. 133 on January 1, 2001, additional assets
     of $93 million and liabilities of $99 million were recorded for U.S. GAAP
     purposes to reflect the fair value of derivatives designated as interest
     rate hedges and the corresponding change in the fair value of items
     designated as hedges. A charge of $2 million, after tax, relating to the
     fair value of hedges was recognized in income and $4 million, after tax,
     relating to the fair value of derivatives designated as cash flow hedges
     was recognized in other comprehensive income as the cumulative effect of
     application of SFAS No. 133.

     During 2003, net gains of $47 million (2002 - $38 million; 2001 - $36
     million) from the hedges of changes in the fair value of long-term debt,
     and net losses of $53 million (2002 - $20 million; 2001 - $44 million) in
     the fair value of the hedged item were included in earnings as an
     adjustment to interest expense and foreign exchange losses. No amounts of
     the derivatives' gains or losses were excluded from the assessment of hedge
     effectiveness in fair value hedging relationships.


                                      F-35


     No amounts were included in income in 2003, 2002 and 2001 with respect to
     ineffectiveness of cash flow hedges. For amounts included in other
     comprehensive income at December 31, 2003, $9 million (2002 - $(5) million;
     2001 - $(3) million) relates to the hedge of interest rate risk, $5 million
     (2002 - $1 million; 2001 - $(2) million) relates to the hedge of foreign
     exchange rate risk, and $(6) million (2002 - nil; 2001 - nil) relates to
     the hedge of energy price risk. Of these amounts, $(5) million is expected
     to be recorded in earnings during 2004.

     At December 31, 2003, additional assets of $107 million (2002 - $198
     million) and additional liabilities of $110 million (2002 - $203 million)
     were recorded for U.S. GAAP purposes to reflect the fair value of
     derivatives designated as hedges and the corresponding change in the fair
     value of items designated as hedges.

(5)  Other expenses include an allowance for funds used during construction of
     $2 million for the year ended December 31, 2003 (2002 - $4 million; 2001 -
     $5 million).

(6)  Under U.S. GAAP, changes in the foreign currency translation adjustment
     account must be recorded as a component of comprehensive income.

(7)  Under U.S. GAAP, a net loss recognized pursuant to SFAS No. 87 "Employers'
     Accounting for Pensions" as an additional pension liability not yet
     recognized as net period pension cost, must be recorded as a component of
     comprehensive income. The net amount recognized at December 31 is as
     follows.

     The accumulated benefit obligation for the Company's DB Plans was $819
     million at December 31, 2003 (2002 - $738 million).

(8)  Under U.S. GAAP, the financial charges related to preferred securities are
     recognized as an expense, rather than dividends.

(9)  Under U.S. GAAP, only enacted rates can be used in measuring deferred tax
     assets and liabilities; use of substantively enacted rates is not
     permitted. The February 2000 and October 2000 Federal budgets would not be
     considered enacted until the proposals were completely enacted into law in
     June 2001 and, accordingly, the related tax recoveries were recognized in
     2001.

(10) Effective January 1, 2003, the Company adopted the provisions of Financial
     Interpretation (FIN) 45 that require the recognition of a liability for the
     fair value of certain guarantees that require payments contingent on
     specified types of future events. The measurement standards of FIN 45 are
     applicable to guarantees entered into after January 1, 2003. For U.S. GAAP,
     the Company has recorded the fair value of the guarantees ($4 million)
     arising on the acquisition of the interest in Bruce Power as a liability
     and an increase in the cost of the investment.

(11) Effective January 1, 2003, the Company adopted the provisions of SFAS No.
     143 "Accounting for Asset Retirement Obligations", which addresses
     financial accounting and reporting for obligations associated with asset
     retirement costs. SFAS No. 143 requires that the fair value of a liability
     for an asset retirement obligation be recognized in the period in which it
     is incurred if a reasonable estimate of fair value can be made. The fair
     value is added to the carrying amount of the associated asset. The
     liability is accreted at the end of each period through charges to
     operating expenses.

     The plant, property and equipment of the regulated natural gas transmission
     operations consist primarily of underground pipelines and above ground
     compression equipment and other facilities. No amount has been recorded for
     asset retirement obligations relating to these assets as it is not possible
     to make a reasonable estimate of the fair value of the liability due to the
     indeterminate timing and scope of the asset retirements. Management
     believes that all retirement costs associated with the regulated pipelines
     will be recovered through tolls in future periods.

     The plant, property and equipment in the power business consists primarily
     of power plants in Canada and the United States. The estimated fair value
     of the liability for the power plants and associated assets as at January
     1, 2003 was $6 million. The asset retirement cost, net of accumulated
     depreciation that would have been recorded if the cost had been recorded in
     the period in which it arose, is recorded as an additional cost of the
     assets as at January 1, 2003. The estimated fair value of the liability as
     at December 31, 2003 was $7 million. The cumulative effect of the
     application of SFAS No. 143 on income with respect to the years ended
     December 31, 2001 and 2002 would have been less than $1 million. The
     Company has no legal liability for asset retirement obligations with
     respect to its investment in Bruce Power and the Sundance A and B power
     purchase arrangements.


                                      F-36


(12) Under U.S. GAAP, the Company is required to record a deferred income tax
     liability for its cost-of-service regulated businesses. As these deferred
     income taxes are recoverable through future revenues, a corresponding
     regulatory asset is recorded for U.S. GAAP purposes.

(13) Current liabilities at December 31, 2003 include dividends payable of $136
     million (2002 - $125 million) and current taxes payable of $271 million
     (2002 - $150 million).

(14) The fair value of the preferred securities at December 31, 2003 was $612
     million (2002 - $743 million). The Company made preferred securities
     charges payments of $57 million for the year ended December 31, 2003 (2002
     - $58 million; 2001 - $77 million).

(15) The Company's Statement of Consolidated Cash Flows under U.S. GAAP would be
     identical to that under Canadian GAAP except that the preferred securities
     charges would be classified with funds generated from continuing
     operations.

OTHER

In 2003, the FASB issued FIN 46 (Revised) "Consolidation of Variable Interest
Entities" that requires the consolidation of certain entities that are
controlled through financial interests that indicate control (referred to as
"variable interests"). Variable interests are the rights or obligations that
convey economic gains or losses from changes in the values of an entity's assets
or liabilities. The holder of the majority of an entity's variable interests
will be required to consolidate the variable interest entity. Adopting the
provisions of FIN 46 (Revised) has had no impact on the U.S. GAAP financial
statements of the Company.


                                      F-37


In May 2003, the FASB issued SFAS No. 150 "Accounting for Certain Financial
Instruments with Characteristics of both Liabilities and Equity". This Statement
establishes standards for how an issuer classifies and measures in its statement
of financial position certain financial instruments with characteristics of both
liabilities and equity. It requires that an issuer classify a financial
instrument that is within its scope as a liability (or an asset in some
circumstances) because that financial instrument embodies an obligation of the
issuer. Many of those instruments were previously classified as equity. Adopting
the provisions of SFAS No. 150 has had no impact on the U.S. GAAP financial
statements of the Company. Effective January 1, 2005, in accordance with
Canadian GAAP, certain instruments that are currently classified as equity will
be classified as liabilities, under new Canadian accounting standards.
