              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 68 through 106. See document 13.4, entitled "U.S.
 GAAP reconciliations of the 2005 Consolidated Audited Financial Statements",
attached to this Form 40-F for a reconciliation of 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 2 through 66 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 2005 fiscal year.

Tax Fees                                                                                             0.12         0.06
All Other Fees                                                                                       0.14         0.05
Total                                                                                           $    3.49    $    2.64

        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 and its subsidiaries' 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 Canadian and US income tax
returns and tax items and tax services related to domestic and international
taxation including income tax, capital tax and Goods and Services 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 regard 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 specified non-audit services. For engagements of
$25,000 CDN or less which are not within the annual pre-approved limit approval
by the Audit Committee is not required, and for engagements between $25,000 CDN
and $100,000 CDN, approval of the Audit Committee chair is required, and in both
instances the Audit Committee is to be informed of the engagement at the next
scheduled Audit Committee meeting. For all engagements of $100,000 CDN or more,
pre-approval of the Audit Committee is required. In all cases, regardless of
dollar amount involved, where there is a potential for conflict of interest
involving the external auditor on an engagement, the Audit Committee chair must
pre-approve the assignment.

        To date, the Registrant has not approved any non-audit services on the
basis of the de-minimis exemptions. All non-audit services have been
pre-approved by the Audit Committee in accordance with the pre-approval policy
described above.




                         OFF-BALANCE SHEET ARRANGEMENTS

        The Registrant has no off-balance sheet arrangements, as defined in this
Form, other than the guarantees described in Note 23 of the Notes to the
Consolidated Financial Statements and document 13.4, entitled U.S. GAAP
Reconciliation of the 2005 Consolidated Audited Financial Statements", attached
to this Form 40-F. The disclosure relating to guarantees in Note 23 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 acquisitions, events or conditions which have had an
influence on that development, are described below.

Developments in Gas Transmission Business

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

2005

In 2005, some of the significant natural gas transmission developments that
occurred involved the sale of common units of TC PipeLines, LP, regulatory
matters including the National Energy Board's ("NEB") decision on the Canadian
Mainline 2004 Tolls and Tariff Application (Phase II) and a settlement relating
to the Alberta System, on-going construction of a natural gas storage facility
located near Edson, Alberta, continued funding of the Mackenzie Valley
Aboriginal Pipeline Limited Partnership (known as "Aboriginal Pipeline Group" or
"APG") for its participation in the Mackenzie Gas Pipeline Project, continued
discussions relating to the proposed Alaska Highway Pipeline Project, launching
of the Keystone crude oil pipeline project and the announcement in January 2006
that firm, long-term contracts were secured for the project, continued work
toward gaining regulatory approval for its two liquified natural gas ("LNG")
projects: Cacouna in Quebec and the Broadwater Energy project, offshore of New
York State in Long Island Sound, acquisition of an additional interest in the
Iroquois Gas Transmission System L.P. ("Iroquois System") and the commencement
of construction of the Tamazunchale Pipeline in east-central Mexico. Further
information about each of

these developments can be found in the MD&A under the heading "TCPL's Strategy -
Gas Transmission" and "Gas Transmission - Opportunities and Developments".

2004

In September 2004, TCPL and Petro-Canada signed a memorandum of understanding
for the development of the Cacouna Energy LNG facility in Cacouna, Quebec,
approximately 15 kilometres northeast of Riviere-du-Loup. The proposed facility
will be capable of receiving, storing and regasifying imported LNG with an
average annual send out capacity of approximately 500 million cubic feet per day
of natural gas. TCPL and Petro-Canada will share equally the construction costs
of the facility, which are estimated to be $660 million. TCPL will operate the
facility while Petro-Canada will contract for the facility's entire
regasification capacity and supply the LNG. The proposed facility requires
regulatory and other approvals from federal, provincial and municipal
governments and regulators and the regulatory approval process is anticipated to
take approximately two years to complete. In September 2005, the village of
Cacouna, Quebec voted 57.2 per cent in favour of an LNG terminal to be built in
the area. Quebec's Ministry of Environment commenced its 45 day public
consultation period on February 22, 2006 regarding its next phase for this
project. TCPL continues to work towards gaining regulatory approval and provided
the necessary approvals are obtained, the facility is anticipated to be in
service towards the end of this decade.

 In November 2004, TCPL acquired the Gas Transmission Northwest System and the
North Baja System from National Energy & Gas Transmission, Inc. ("NEGT") for
US$1.7 billion, including approximately US$0.5 billion of assumed debt, subject
to typical closing adjustments. The 2,174 kilometre Gas Transmission Northwest
System, formerly known as Pacific Gas Transmission, extends from a connection
point on TCPL's BC System and Foothills System near Kingsgate, British Columbia
on the B.C./Idaho border to a point near Malin, Oregon on the Oregon/California
border. The natural gas transported on this system originates primarily in
Canada and is supplied to markets in the Pacific Northwest, California and
Nevada. The 129 kilometre North Baja System extends from a point near Ehrenberg,
Arizona to a point near Ogilby, California on the California/Mexico border. The
natural gas transported on the North Baja System comes primarily from supplies
in the southwestern U.S. for markets in northern Baja California, Mexico.

 In November 2004, TCPL and Shell US Gas & Power LLC ("Shell") announced plans
to jointly develop an offshore LNG regasification terminal, Broadwater Energy,
in the New York State waters of Long Island Sound. The proposed floating storage
and regasification unit will be capable of receiving, storing and regasifying
imported LNG with an average send out capacity of approximately one billion
cubic feet ("Bcf") per day of natural gas. TCPL and Shell will build and install
a floating storage and regasification unit at a location approximately 15
kilometres off the Long Island coast and 18 kilometres off the Connecticut
coast. TCPL will own 50 per cent of Broadwater Energy LLC, which will own and
operate the facility, while Shell will contract for the facility's entire
regasification capacity and supply the LNG. The estimated cost of construction
is approximately US$700 million to US$1 billion. The proposed Broadwater Energy
LNG facility requires regulatory approval from federal and state governments
before construction can begin and the regulatory approval process is anticipated
to take up to three years to complete. Provided the necessary approvals are
granted and commercial commitments obtained, the facility could be in service in
late 2010 or early 2011. TCPL, on behalf of the Broadwater Energy project, filed
a formal application with the U.S. Federal Energy Regulatory Commission ("FERC")
in January 2006, for federal approval to construct and operate Broadwater.

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, extends 1,040 kilometres and has two legs: one which
originates south of Caroline, Alberta and runs along the foothills of the Rocky
Mountains through the Crowsnest Pass to Kingsgate, B.C. where it connects to the
Gas Transmission Northwest System; and the other which originates south of
Caroline, Alberta and runs southeast across Alberta and Saskatchewan to the
Canada-U.S. border near Monchy, Saskatchewan where it interconnects with
Northern Border Pipeline Company ("Northern Border Pipeline"). The Foothills
System carries over 30 per cent of all Canadian natural gas exports to the U.S.

                                                 TRANSCANADA PIPELINES LIMITED 3


 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 the APG reached a funding and participation agreement. TCPL agreed to
finance the APG's share of project development costs in exchange for certain
rights in the Mackenzie Gas Pipeline Project, including a right to an ownership
interest in the pipeline at the decision to construct, preferential rights of
first refusal and preferential expansion rights and the right of connection of
the Mackenzie Delta natural gas flow into the Alberta System. For current
information about the Mackenzie Gas Pipeline Project, please refer to the MD&A
under the heading "Gas Transmission - Opportunities and Development - Mackenzie
Gas Pipeline Project".

 Through acquisitions that took place in September and December 2003, TCPL
increased its ownership interest in Portland Natural Gas Transmission System
Partnership ("Portland") in the northeastern U.S. from 33.3 per cent to 61.7 per
 cent.

Developments in Power Business

In the past three years, TCPL has grown its power business and, in particular,
has increased its generation capacity from facilities it owns, operates and/or
controls, including those under construction or in development, from 4,667
megawatts ("MW") in 2003 to 6,736 MW at Year End. Summarized below are
significant developments that have occurred in TCPL's power business over the
last three years.

2005

The significant power developments that occurred in 2005 included the
advancement of the 739.5 MW Cartier Wind Energy project ("Cartier Wind Energy"),
the sale of TCPL's approximate 11 per cent interest in P.T. Paiton Energy
Company ("Paiton Energy") to subsidiaries of The Tokyo Electric Power Company
resulting in gross proceeds of US$103 million ($122 million), the acquisition of
the 756 MW Sheerness Power Purchase Arrangement for $585 million, the
restructuring of Bruce Power L.P. ("Bruce B") and the execution of agreements by
Bruce Power A L.P. ("Bruce A") with the Ontario Power Authority to restart and
refurbish units at Bruce A, the acquisition of power generation assets from
USGen New England, Inc. ("USGen") for US$505 million, the sale of all of TCPL's
interests in TransCanada Power, L.P. ("Power LP") to EPCOR Utilities Inc. for
net proceeds of $523 million in August 2005 and OSP's successful restructuring
of its long-term natural gas fuel supply contracts with its supplier.

 Further information about each of these power developments can be found in the
MD&A under the heading "TCPL's Strategy - Power". Further information can be
found in the MD&A about Bruce A and Bruce B under the heading "Power - Financial
Analysis - Bruce Power", about the sale of Paiton Energy under "Power -
Highlights - Net Earnings", "Power - Power Results-at-a-Glance", "Discontinued
Operations" and elsewhere, and about the Power LP under the heading "Power -
Financial Analysis - Power LP Investment".

2004

TCPL received approval from the Quebec government in April 2004, to develop the
550 MW natural gas-fired Becancour cogeneration plant which is located at an
industrial park near Trois-Rivieres, Quebec ("Becancour Plant") and which will
supply its entire power output to Hydro-Quebec Distribution under a 20 year
power purchase contract. The Becancour Plant will also supply steam to two other
companies located within the same industrial park. Construction of the 550 MW
Becancour Plant began in the third quarter of 2004. The cost of the Becancour
Plant is estimated to be $550 million, and the plant is expected to be in
service in late 2006.

 In April 2004, TCPL sold its ManChief and Curtis Palmer power plants to Power
LP for approximately US$402.6 million, excluding closing adjustments. The
acquisition was partially financed by Power LP through a public offering of
subscription receipts which were subsequently converted into limited partnership
units. TCPL did not take up its full pro rata share of the units and as a
result, its interest in Power LP was reduced from 35.6 per cent to 30.6 per
cent.

4 TRANSCANADA PIPELINES LIMITED


 Cartier Wind Energy, of which 62 per cent is owned by TCPL, was awarded six
wind energy projects by Hydro-Quebec Distribution in October 2004, representing
a total of 739.5 MW in the Gaspe region of Quebec. The six projects are
distributed throughout the Gaspesie-Iles-de-la-Madeleine region and the Regional
County Municipality of Matane and are expected to cost a total of more than $1.1
 billion to develop and construct. Construction of the first two of six wind
farm projects will commence in early 2006 and the first of the two projects is
expected to be in service in late 2006. The entire output will be supplied to
Hydro-Quebec Distribution under a 20-year power purchase contract.

 Construction of the 165 MW MacKay River power plant located in Alberta was
completed in 2003 and the plant was put into commercial service in 2004.

 Construction of 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") was completed by the end of 2004 and was commissioned in January 2005.
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.

2003

In February 2003, TCPL, as part of a consortium, acquired a 31.6 per cent
interest in Bruce B and a 33.3 per cent interest in Bruce Power Inc., the
general partner of Bruce B. Bruce B leases its generation facilities from
Ontario Power Generation Inc. ("OPG"). The facilities consist of eight nuclear
reactors, five of which were operational at the end of 2003, with a capacity of
3,950 MW. An additional reactor with capacity of 750 MW commenced commercial
operations in March 2004.

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

Recent Developments

On February 9, 2006, TCPL announced the filing by its subsidiary, North Baja
Pipeline LLC, of an application with the FERC for a certificate for a two-phase
expansion of its existing natural gas pipeline in southern California and the
construction of a new pipeline lateral in California's Imperial Valley.

 TCPL announced on February 15, 2006, that it will sell its 17.5 per cent
general partner interest in Northern Border Partners, L.P. to a subsidiary of
ONEOK, Inc. for a net payment of US$30 million subject to certain closing
adjustments. In addition, TCPL will become the operator of Northern Border
Pipeline ("NBPL") in early 2007. The transaction is expected to close in the
second quarter of 2006 and is part of a series of transactions that will also
result in TC PipeLines, LP, an affiliate of TCPL, acquiring an additional 20 per
 cent interest in NBPL from Northern Border Partners, L.P., bringing its total
general partnership interest in NBPL to 50 per cent.

Regulation

Canadian Mainline

Under the terms of the National Energy Board Act (Canada), 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, including the return on
the Canadian Mainline's average investment base. In addition, new facilities are
approved by the NEB before construction begins and the NEB regulates the
operation of the Canadian Mainline. Net earnings of the Canadian Mainline are
affected by changes in investment base, the return on equity, the level of
deemed common equity and the potential for incentive earnings.

Other Interests

Cancarb Limited

TCPL owns Cancarb Limited, a world scale 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.

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 TCPL's Board of Directors ("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 by way of a formal reporting process. In addition,
TCPL's management system and performance in the HS&E area are assessed by an
independent outside firm every three years or more often if the HS&E Committee
requests it. The most recent assessment was completed by PricewaterhouseCoopers
in January 2004. These assessments involve senior executive interviews, review
of policies and objectives, performance measurement and reporting.

 TCPL has an HS&E management system modeled after elements of the International
Organization for Standardization's standard for environmental management systems
which is known as ISO 14001, to facilitate the focus of resources on the areas
of greatest risk to the organization's business activities relating to HS&E. The
system highlights opportunities for improvement, enables TCPL to work towards
defined HS&E expectations and objectives, and provides a competitive business
advantage. HS&E outside, independent assessments, 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.

Environment

Climate change is a strategic issue for TCPL. In Canada, TCPL's fossil fuelled
power plants, pipeline assets and carbon black facilities are expected to be
covered under legislation for large final emitters. While the broad elements of
the proposed regulations to reduce greenhouse gas emissions intensities from
large industrial emitters have been

                                                 TRANSCANADA PIPELINES LIMITED 9


established, key policy elements remain outstanding including details of
compliance options that entities may use to fulfill compliance obligations. At
this time, it is difficult to determine the level of impact to TCPL's Canadian
assets until these and other key policy elements have been defined.

 In 2006, TCPL will continue with its strategy for managing the climate change
issue. This strategy includes activities such as:

    *
        energy conservation through improvements to overall system efficiency;


    *
        conducting research and development work designed to reduce greenhouse
        gas emissions;


    *
        gaining experience with flexible market mechanisms;


    *
        participation in government-led policy forums; and


    *
        taking part in public awareness initiatives and education programs
        focused on climate change and air quality issues.

 In addition to these activities, TCPL also ensures that the potential business
risks and opportunities posed by increasing environmental priorities are
considered when making decisions regarding TCPL's businesses.

LEGAL PROCEEDINGS

The Canadian Alliance of Pipeline Landowners' Association and two individual
landowners have commenced an action under Ontario's Class Proceedings Act, 1992,
against TCPL and Enbridge Inc. for damages of $500 million alleged to arise from
the creation of a control zone within 30 metres of the pipeline pursuant to
section 112 of the National Energy Board Act. TCPL believes the claim is without
merit and will vigorously defend the action. TCPL has made no provision for any
potential liability. Any liability would be dealt with through the regulatory
process.

 TCPL 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 TCPL's management that the resolution of such proceedings and actions
will not have a material impact on TCPL's consolidated financial position or
results of operations.

TRANSFER AGENT AND REGISTRAR

TCPL's transfer agent and registrar is Computershare Trust Company of Canada
with transfer facilities in the Canadian cities of Vancouver, Calgary, Winnipeg,
Toronto, Montreal and Halifax.

AUDITOR AND INTEREST OF EXPERTS

TCPL's auditor is KPMG LLP ("External Auditor") and as of February 27, 2006, the
partners of the External Auditor have advised that they do not beneficially own,
directly or indirectly, any securities of TCPL. TCPL collects this information
from the External Auditor but otherwise has no direct knowledge of individual
holdings of its securities.

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.

Gas Transmission

TCPL faces competition in its gas transmission business at both the supply and
market ends of its systems. The competition is a result of other pipelines
accessing an increasingly mature western Canadian sedimentary basin and serving
some of the same markets as TCPL. In addition, the continued expiration of firm
transportation contracts has resulted in significant reductions in firm
contracted capacity on both the Canadian Mainline and Alberta System. As well,
regulatory decisions continue to have significant impact on the financial
returns for and future investments in TCPL's Canadian wholly-owned pipelines.

 Further information about risks in TCPL's natural gas transmission business can
be found under the headings "Gas Transmission - Opportunities and Developments"
and "Gas Transmission - Business Risks" in the MD&A.

Power

TCPL's power business can be affected by a variety of factors including
competition from other market participants, fluctuating market demand, weather,
reliance on the supply of feed stocks such as natural gas, water, coal and
uranium, fluctuating feed stock prices, fluctuating electricity prices,
unexpected outages, third party power plant operator performance, power
transmission disruptions and regulatory changes and influences.

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

 In addition, Bruce A and Bruce B, in which TCPL holds material interests, are
subject to risks related to the operation and maintenance of nuclear power
generating facilities, including risks relating to the use, handling,
containment and storage of radioactive materials; limitation on the amounts and
types of insurance that are commercially available to cover any related
liabilities that may arise from these operations; changes in and varying
interpretations of the extensive federal regulations that apply to Bruce A's and
Bruce B's nuclear operations; modifications needed to meet increasing security
requirements; and repairs, modifications, replacements and outages that may be
necessitated as a result of testing and inspection programs which, themselves,
may need to be enhanced in coming years to improve operations or satisfy
increasing regulatory or other requirements.

Other

Further information about TCPL's risk management activities can be found under
the heading "Risk Management" in the MD&A.

DIVIDENDS

All of TCPL's common shares are held by TransCanada and as a result, any
dividends declared by TCPL on its common shares are paid to TransCanada. TCPL's
Board of Directors has not adopted a formal dividend policy. The Board reviews
the financial performance of TCPL quarterly and makes a determination of the
appropriate level of dividends to be declared on its common shares in the
following quarter. Provisions of various trust indentures and credit
arrangements to which TCPL is a party, restrict TCPL's ability to declare and
pay dividends to TransCanada and preferred shareholders under certain
circumstances and, if such restrictions apply, they may, in turn, have an impact
on TransCanada's ability to declare and pay dividends on its common and
preferred shares. In the opinion of TCPL management, such provisions do not
restrict or alter TCPL's ability to declare or pay dividends.

    the aggregate amount divided by the total outstanding common shares of TCPL.

DESCRIPTION OF CAPITAL STRUCTURE

Share Capital

TCPL's authorized share capital consists of an unlimited number of common
shares, of which approximately 483,344,109 were issued and outstanding at Year
End, and an unlimited number of first preferred shares and second preferred
shares issuable in series. There were 4,000,000 Series U and 4,000,000 Series Y
first preferred shares issued and outstanding at Year End. The following is a
description of the material characteristics of each of these classes of shares.

Common Shares

As the holder of all of TCPL's issued common shares, TransCanada holds all the
voting rights in those common shares.

First Preferred Shares, Series U

Subject to certain limitations, the Board may, from time to time, issue first
preferred shares in one or more series and determine for any such series, its
designation, number of shares and respective rights, privileges, restrictions
and conditions. The first preferred shares as a class, have, among others,
provisions to the following effect.

 The holders of the first preferred shares, Series U are entitled to receive, as
and when declared by the Board, fixed cumulative preferential cash dividends at
an annual rate of $2.80 per share, payable quarterly.

 The first preferred shares of each series shall rank on a parity with the first
preferred shares of every other series, and shall be entitled to preference over
the common shares and any other shares ranking junior to the first preferred
shares with respect to the payment of dividends, the repayment of capital and
the distribution of assets to TCPL in the event of a liquidation, dissolution or
winding up of TCPL.

 TCPL is entitled to purchase for cancellation, some or all of the first
preferred shares, Series U outstanding at the lowest price which such shares are
obtainable, in the opinion of the Board, but not exceeding $50.00 per share plus
costs of purchase. Furthermore, TCPL may redeem, on or after October 15, 2013,
some or all of the first preferred shares, Series U upon payment for each share
at $50.00 per share.

 Except as provided by the Canada Business Corporations Act or as referred to
below, the holders of the first preferred shares will not have any voting rights
nor will they be entitled to receive notice of or to attend shareholders'
meetings unless and until TCPL fails to pay, in the aggregate, six quarterly
dividends on the first preferred shares, Series U.

 The provisions attaching to the first preferred shares as a class may be
modified, amended or varied only with the sanction of the holders of the first
preferred shares as a class. Any such sanction to be given by the holders of the
first preferred shares may be given by the affirmative vote of the holders of
not less than 662/3 per cent of the first preferred shares represented and voted
at a meeting or adjourned meeting of such holders.

12 TRANSCANADA PIPELINES LIMITED



First Preferred Shares, Series Y

The rights, privileges, restrictions and conditions attaching to the first
preferred shares, Series Y are substantially identical to those attaching to the
first preferred shares, Series U, except that the first preferred shares, Series
 Y are redeemable by TCPL after March 5, 2014.

 Credit ratings are intended to provide investors with an independent measure of
credit quality of an issue of securities. Credit ratings are not recommendations
to purchase, hold or sell securities and do not address the market price or
suitability of a specific security for a particular investor. There is no
assurance that any rating will remain in effect for any given period of time or
that any rating will not be revised or withdrawn entirely by a rating agency in
the future if, in its judgment, circumstances so warrant. A description of the
rating agencies' credit ratings listed in the table above is set out below.

Dominion Bond Rating Service (DBRS)

DBRS has different rating scales for short and long-term debt and preferred
shares. "High" or "low" grades are used to indicate the relative standing within
a rating category. The absence of either a "high" or "low" designation indicates
the rating is in the "middle" of the category. The R-1 (low) rating assigned to
TCPL's short-term debt is the third highest of ten rating categories and
indicates satisfactory credit quality. The overall strength and outlook for key
liquidity, debt and profitability ratios is not normally as favourable as with
higher rating categories, but these considerations are still respectable. Any
qualifying negative factors that exist are considered manageable, and the entity
is normally of sufficient size to have some influence in its industry. The A
ratings assigned to TCPL's senior secured and senior unsecured debt and the A
(low) rating assigned to its subordinated debt are the third highest of ten
categories for long-term debt. Long-term debt rated A is of satisfactory credit
quality. Protection of interest and principal is still substantial, but the
degree of strength is less than that of AA rated entities. While a respectable
rating, entities in the A category are considered to be more susceptible to
adverse economic conditions and have greater cyclical tendencies than higher
rated entities. The Pfd-2 and Pfd-2 (low) ratings assigned to TCPL's junior
subordinated debt and preferred shares are the second highest of six rating
categories for preferred shares. Preferred shares rated Pfd-2 are of
satisfactory credit quality. Protection of dividends and principal is still
substantial; however, earnings, the balance sheet and coverage ratios are not as
strong as Pfd-1 rated companies.

Moody's Investor Services (Moody's)

Moody's has different rating scales for short and long-term obligations.
Numerical modifiers 1, 2 and 3 are applied to each rating classification, with 1
 being the highest and 3 being the lowest. The P-1 rating assigned to TCPL's
short-term debt is the highest of four rating categories and indicates a
superior ability to repay short-term debt obligations. The A2 ratings assigned
to TCPL's senior secured and senior unsecured debt and the A3 ratings assigned
to its subordinated debt and junior subordinated debt are the third highest of
nine rating categories for long-term obligations. Obligations rated A are
considered upper-medium grade and are subject to low credit risk. The Baa1
rating assigned to TCPL's preferred shares is the fourth highest of nine rating
categories for long-term obligations. Obligations rated Baa are subject to
moderate credit risk, are considered medium-grade, and as such, may possess
certain speculative characteristics.

Standard & Poor's (S&P)

S&P has different rating scales for short and long-term obligations. Ratings may
be modified by the addition of a plus (+) or minus (-) sign to show the relative
standing within a particular rating category. The A and A- ratings assigned to
TCPL's senior secured and senior unsecured debt, respectively, are the third
highest of ten rating categories for long-term obligations. An A rating
indicates the obligor's capacity to meet its financial commitment is strong;
however, the obligation is somewhat susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in higher
rated categories. The BBB+ rating assigned to TCPL's subordinated debt and the
BBB ratings assigned to its junior subordinated debt and preferred shares are
the fourth highest of ten rating categories for long-term obligations. An
obligation rated BBB exhibits adequate protection parameters. However, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity of the obligor to meet its financial commitment on the
obligation.

 TCPL's directors are, in the opinion of the Board, well qualified to act as
directors. With the exception of Messrs. Kvisle and Stewart, each director,

independent within the meaning of Canadian and applicable U.S. securities law,
regulation and policy and NYSE requirements, and has established his or her
eligibility and willingness to serve as a director. The proposed nominees will
also be the directors of TransCanada.

CORPORATE GOVERNANCE

The Board and the members of TCPL's management are committed to the highest
standards of corporate governance. TCPL's corporate governance practices comply
with the governance rules of the Canadian Securities Administrators ("CSA"),
those of the NYSE applicable to foreign issuers and of the U.S. Securities and
Exchange Commission ("SEC"), and those mandated by the United States
Sarbanes-Oxley Act of 2002 ("SOX"). As a non-U.S. company, TCPL is not required
to comply with most of the NYSE corporate governance listing standards; however,
except as summarized on its website at www.transcanada.com, the governance
practices followed are in compliance with the NYSE standards for U.S. companies
in all significant respects. TCPL is in compliance with the CSA's Multilateral
Instrument 52-110 pertaining to audit committees. TCPL is also in compliance
with National Policy 58-201, Corporate Governance Guidelines, and National
Instrument 58-101, Disclosure of Corporate Governance Practices (collectively,
the "Canadian Governance Guidelines"). In 2005, the Canadian Governance
Guidelines came into effect and for purposes of the TSX replaced the TSX
Corporate Governance Guidelines.

Compliance with Canadian Governance Guidelines

The "Disclosure of Corporate Governance Practices" addressing disclosure in
accordance with the Canadian Governance Guidelines is attached to this AIF at
Schedule "B". It has been approved by the Governance Committee and the Board.

Audit Committee

TCPL has an Audit Committee which is responsible for assisting the Board in
overseeing the integrity of TCPL's financial statements and compliance with
legal and regulatory requirements and in ensuring the independence and
performance of TCPL's internal and external auditors. The members of the Audit
Committee at Year End were Harry G. Schaefer (Chair), Douglas D. Baldwin, Kevin
E. Benson, Paule Gauthier and Paul L. Joskow. Mr. Jackson is a non-voting member
of the Audit Committee.

 The Board believes that the composition of the Audit Committee reflects a high
level of financial literacy and expertise. Each member of the Audit Committee
has been determined by the Board to be "independent" and "financially literate"
within the meaning of the definitions under Canadian and U.S. securities laws
and the NYSE rules. In addition, the Board has determined that Mr. Schaefer is
an "Audit Committee Financial Expert" as that term is defined under U.S.
securities laws. The Board has made these determinations based on the education
and breadth and depth of experience of each member of the Audit Committee. The
following is a description of the education and experience,

20 TRANSCANADA PIPELINES LIMITED



apart from their respective roles as directors of TCPL, of each member of the

committees of two other public companies.

Pre-Approval Policies and Procedures

TCPL'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 specified non-audit services. For engagements of $25,000 or
less which are not within the annual pre-approved limit approval by the Audit
Committee is not required, and for engagements between $25,000 and $100,000,
approval of the Audit Committee chair is required, and in both instances the
Audit Committee is to be informed of the engagement at the next scheduled Audit
Committee meeting. For all engagements of $100,000 or more, pre-approval of the
Audit Committee is required. In all cases, regardless of the dollar amount
involved, where there is a potential for conflict of interest involving the
external auditor on an engagement, the Audit Committee chair must pre-approve
the assignment.

 To date, TCPL has not approved any non-audit services on the basis of the
de-minimis exemptions. All non-audit services have been pre-approved by the
Audit Committee in accordance with the pre-approval policy described above.

The Board and members of TCPL's management are not aware of any existing or
potential material conflicts of interest between TCPL or a subsidiary and any
director or officer of TCPL or its subsidiary. Directors and officers of TCPL
and its subsidiaries are required to disclose the existence of existing or
potential conflicts in accordance with TCPL policies governing directors and
officers and in accordance with the Canada Business Corporations Act. If a
director or officer has such a conflict, TCPL requires that the director or
officer absent himself or herself from any discussion or voting relating to the
matter giving rise to the material existing or potential conflict.

officer, director or employee of TCPL or its subsidiaries, no proposed nominee
as a director of TCPL, or any associate of any such director, executive officer

guarantee, support agreement, letter of credit or other similar arrangement or
understanding provided by TCPL or any of its subsidiaries.

(1)
    The information as to shares beneficially owned or over which control or
    direction is exercised, not being within the knowledge of TransCanada, has
    been furnished by each of the nominees. Except as indicated in these notes,
    the nominees have sole voting and dispositive power with respect to the
    securities listed above. As to each class of shares of TransCanada, its
    subsidiaries and affiliates, the percentage of outstanding shares
    beneficially owned by any one director or nominee or by all directors and
    officers of TransCanada as a group does not exceed 1% of the class
    outstanding.


(2)
    The value of a deferred share unit is tied to the value of TransCanada's
    common shares. A deferred share unit is a bookkeeping entry, equivalent to
    the value of a TransCanada common share, and does not entitle the holder to
    voting or other shareholder rights, other than the accrual of additional
    deferred share units for the value of dividends. A director cannot redeem
    deferred share units until the director ceases to be a member of the Board.
    Canadian directors can then redeem their units for cash or shares while U.S.
     directors can only redeem their units for cash. Mr. Kvisle is an employee
    of TransCanada and participates in the ESU program; he does not participate
    in the DSU program.

    Securities owned, controlled or directed include common shares that Mr.
    Baldwin has a right to acquire through the exercise of stock options that
    are vested under the Stock Option Plan, which plan is described elsewhere in
    this AIF. Directors as such do not participate in the Stock Option Plan. Mr.
     Baldwin, as a former employee of TransCanada, has the right to acquire
    150,000 common shares under vested stock options, which amount is included
    in this column.

    The shares listed include 2,500 shares held by Mr. Hawkins' wife.

    Kvisle has a right to acquire through the exercise of stock options that are
    vested under the Stock Option Plan, which plan is described elsewhere in
    this AIF. Directors as such do not participate in the Stock Option Plan. Mr.
     Kvisle, as an employee of TransCanada, has the right to acquire 655,833
    common shares under vested stock options, which amount is included in this
    column.

(7)
    The shares listed do not include 700 common shares held by Mr. Schaefer's
    wife and 5,500 common shares held by a company controlled by Mr. Schaefer's
    wife. Mr. Schaefer disclaims beneficial ownership of, or control or
    direction over, such shares.

COMPENSATION OF DIRECTORS

TransCanada's directors also serve as directors of TCPL. An aggregate fee is
paid for serving on the Boards of TransCanada and TCPL. Since TransCanada does
not hold any assets directly, other than the common shares of TCPL, all
directors' costs are assumed by TCPL according to a management services
agreement between the two companies. The meetings of the Boards and committees
of TransCanada and TCPL run concurrently.

Minimum Share Ownership Guidelines

The Board believes that directors can more effectively represent the interests
of shareholders if they have a significant investment in the common shares of
TransCanada, or their economic equivalent. As a result, TransCanada requires
each director to acquire and hold a minimum number of common shares, or their
economic equivalent, equal in value to five times the director's annual cash
retainer fee. Directors have a maximum of five years to reach this level of
ownership. The level of ownership can be achieved by direct purchase of common
shares, by participation in the TransCanada Dividend Reinvestment Plan or by
means of directing cash retainer fees into, or otherwise acquiring units under,
the Share Unit Plan for Non-Employee Directors (1998) (the "DSU Plan"),
described under the heading "Share Unit Plan for Non-Employee Directors" below.

 All of the current directors, other than Mr. Draper who became a member of the
Board on June 15, 2005, have achieved the minimum share ownership.

 The following table sets out the common share and DSU ownership interest in
TransCanada of each of the individuals who have been proposed for election as
directors at the TransCanada Annual Meeting as at the date hereof and as at

                                                TRANSCANADA PIPELINES LIMITED 25

Board and Committee Remuneration

TCPL's director compensation practices are designed to reflect the size and
complexity of TCPL and to reinforce the emphasis TCPL places on shareholder
value by linking a portion of directors' compensation to the value of common
shares. The market competitiveness of director compensation is assessed against
the Comparator Group (as defined under the heading "Executive Compensation and
Other Information - Report on Executive Compensation") and a general industry
sample of Canadian companies of similar size and scope to TCPL.

 For the financial year ended December 31, 2005, each director who was not an
employee of TCPL, other than the Chair, was paid in quarterly installments in
arrears as follows:
Retainer fee                                                                               $30,000 per annum
Committee retainer fee                                                                     $3,000 per annum
Committee Chair retainer fee                                                               $4,000 per annum
Board and Committee attendance fee                                                         $1,500 per meeting
Committee Chair attendance fee                                                             $1,500 per meeting

 The Chair, who was paid none of the directors' fees outlined above, was paid a
retainer fee of $300,000 per annum in respect of his duties as Chair, $3,000 per
chaired Board meeting, and was reimbursed for certain office and other expenses.
In 2005, Mr. R.F. Haskayne served as Chair from January 1 to April 29 and Mr.
S.B. Jackson served as Chair from April 30 to December 31. Half of Mr. Jackson's
retainer fee for acting as Chair was paid in DSUs. The Vice-Chair was paid a
retainer fee of $12,000 per annum in respect of his duties as Vice-Chair, in
addition to his other director's fees as outlined above. Each committee chair is
entitled to claim a per diem for time spent on committee activities outside of
the committee meetings. Additionally, directors other than the Chair and the CEO
receive, in respect of their service as directors, an annual grant of units
under the DSU Plan. See "Share Unit Plan for Non-Employee Directors". Fees are
paid quarterly and are pro-rated from the date of the director's appointment to
the Board and the relevant committees.

 TCPL pays a travel fee of $1,500 per meeting for which round trip travel time
exceeds three hours, and reimburses the directors for out-of-pocket expenses
incurred in attending such meetings. Directors who are U.S. residents are paid
the same amounts as outlined above in U.S. dollars.

Fees Paid to Directors in 2005(1)

The following table sets out the total fees paid in cash and the value of the
DSUs awarded or credited for each non-employee director in 2005 as at the date
of grant, unless otherwise stated. Mr. Kvisle, as an employee of TCPL, receives
no cash fees or DSUs as a director.

 Directors generally direct their retainer fee to be paid in DSUs until the
minimum share ownership guideline is reached, and are always entitled to direct
their retainer fee to be paid in DSUs. In 2005, D.D. Baldwin, K.E. Benson, D.H.
Burney, E.L. Draper, P. Gauthier, K.L. Hawkins and D.P. O'Brien received their
retainer fees in DSUs. In a year that a director,

other than the Chair, chooses to receive the retainer fee in DSUs, 100% of the
retainer fee must be credited as DSUs from the date the election is received.
Half of Mr. Jackson's retainer fee for acting as Chair was paid in DSUs.

Share Unit Plan for Non-Employee Directors

The Share Unit Plan for Non-Employee Directors (1998) was established in 1998
and was last amended and restated in January 2005. The DSU Plan allows eligible
Board members, on a quarterly basis, to direct their annual directors' retainer
fee or, at the discretion of the Governance Committee, other board-related fees,
to acquire units representing the right to acquire common shares or their cash
equivalent. The DSU Plan also allows the Governance Committee to grant units as
additional directors' compensation. In September 2005, a grant of 3,000 DSUs was
made to each director other than the Chair and the CEO.

 Initially the value of a DSU is equal to the market value of a common share at
the time the directors are credited with the units. Thus each grant of 3,000
DSUs in September 2005 had an initial cash value of approximately $109,290. The
value of a DSU, when redeemed, is equivalent to the market value of a common
share at the time the redemption takes place. In addition, at the time dividends
are declared and paid on the common shares each DSU accrues an amount equal to
such dividends, which amount is then reinvested in additional DSUs at a price
equal to the then market value of a common share. DSUs cannot be redeemed until
the director ceases to be a member of the Board. Canadian directors may redeem
for cash or common shares at their option. U.S. directors may only redeem for
cash.
