By Order of the Board of Directors,

Donald J. DeGrandis

Vice President and Corporate Secretary

Calgary, Alberta

February 22, 2010

This Management Proxy Circular (“Proxy Circular”) is furnished in connection with the solicitation of proxies by the management of TransCanada Corporation (“TransCanada” or the “Company”) to be used at the Annual and Special Meeting (the “Meeting”) of holders of common shares (the “common shares”) of the Company to be held in Calgary, Alberta on April 30, 2010 and at any adjournment thereof, for the purposes set out in the accompanying Notice of Annual and Special Meeting (the “Notice of Meeting”).

Mailing of this Proxy Circular and the form of proxy will commence on March 24, 2010. The cost of soliciting proxies will be borne by TransCanada. While most proxies will be solicited by mail only, some shareholders may also be contacted by TransCanada employees.

TransCanada will provide proxy materials to brokers, custodians, nominees and fiduciaries and will request that such materials be promptly forwarded to the beneficial owners of common shares registered in the names of such brokers, custodians, nominees and fiduciaries.

Unless otherwise stated, the information contained in this Proxy Circular is given as of February 22, 2010 and all dollar amounts are in Canadian dollars.

For those shareholders who cannot attend the Meeting in person, TransCanada has made arrangements to provide a live webcast of the Meeting in English and French. Details on how shareholders may listen to and view the proceedings on the webcast will be found on TransCanada’s website at www.transcanada.com and will be provided in a news release prior to the Meeting.

TransCanada’s principal corporate and executive offices are located at 450 First Street S.W., Calgary, Alberta, T2P 5H1.

VOTING MATTERS

At the Meeting, shareholders will vote on: the election of directors; the appointment of auditors; amendments to and reconfirmation of the Company’s Stock Option Plan; the ratification and approval of the Company’s Shareholder Rights Plan; and, on an advisory basis, TransCanada’s approach to executive compensation.

Record Date for Notice of Meeting and Provisions Relating to Voting

The Board of Directors of TransCanada (the “Board” or the “Board of Directors”) has fixed March 2, 2010 as the record date for the purpose of determining shareholders entitled to receive the Notice of Meeting. TransCanada will prepare, no later than 10 days following the record date, an alphabetical list of registered shareholders who are entitled to vote as of the record date, showing the number of common shares held by each such shareholder. Each person named on the list of shareholders is entitled to one vote for each share held. The list is available for inspection during usual business hours at the office of Computershare Trust Company of Canada (“Computershare”), Suite 600, 530 - Eighth Avenue S.W., Calgary, Alberta, T2P 3S8 and will be available for inspection at the Meeting.

Voting Shares and Principal Shareholders

As of February 22, 2010, there are 686,798,078 common shares of TransCanada outstanding. Each common share carries the right to one vote on any matter properly coming before the Meeting.  A simple majority of votes (50% plus one vote) is required to approve all matters set forth in the Notice of Meeting.  In addition to TransCanada’s outstanding common shares, there are 22,000,000 first preferred shares, series 1 of TransCanada outstanding as at February 22, 2010.  The first preferred shares, series 1 do not have the right to vote at the Meeting.

To the knowledge of the directors and officers of TransCanada, no person or corporation beneficially owns, directly or indirectly, or exercises control or direction over, more than 10% of the outstanding common shares.

Confidentiality of Votes

Proxies are counted and tabulated by Computershare, the transfer agent of TransCanada, in such a manner as to preserve the confidentiality of the votes of shareholders except: (a) as necessary to meet applicable legal requirements; (b) in the event of a proxy contest; or (c) in the event a shareholder has made a written comment on the form of proxy.

VOTING BY PROXY

Registered Owners

Registered shareholders may vote in person at the Meeting or may give another person authority to vote at the Meeting on their behalf by appointing a proxyholder. Please vote, sign, date and return the form in the envelope provided to Computershare, so that it arrives no later than 4:30 p.m. (Eastern Daylight Time) on Tuesday, April 27, 2010. You may also cast your vote by telephone or internet by following the instructions provided on the form. If you choose to vote by telephone or internet, your vote must also be cast no later than 4:30 p.m. (Eastern Daylight Time) on Tuesday, April 27, 2010.  If you vote by proxy, by telephone or on the internet, you may still attend the Meeting but may not vote again.

Beneficial Owners

The information set forth in this section is of significant importance to many shareholders who do not hold their common shares in their own name. Only proxies deposited by shareholders whose names appear on the records of TransCanada as the registered holders of common shares can be recognized and acted upon at the Meeting. If common shares are listed in your account statement provided by your broker, then, in almost all cases, those common shares will not be registered in your name on the records of TransCanada. Such common shares will likely be registered under the name of your broker or an agent of that broker. In Canada, the vast majority of such shares are registered under the name of CDS & Co., the registration name for CDS Clearing and Depository Services Inc., which acts as nominee for many Canadian brokerage firms. Common shares held by your broker or its nominee can only be voted upon your instructions. Without specific instructions, your broker, its agent or its nominee is prohibited from voting your common shares.

Therefore, beneficial shareholders should ensure that instructions respecting the voting of their common shares are communicated to the appropriate person.

Applicable regulatory policy requires your broker to seek voting instructions from you in advance of a shareholder meeting. Every broker has its own mailing procedures and provides its own return instructions, which you should carefully follow in order to ensure that your common shares are voted at the Meeting. Often, the form of proxy supplied by your broker is similar to the form of proxy provided to registered shareholders.  However, its purpose is limited to instructing the registered shareholder how to vote on your behalf.  The majority of brokers now delegate responsibility for obtaining instructions from clients to Broadridge Financial Solutions, Inc. (“Broadridge”).  Broadridge mails a voting instruction form in lieu of the form of proxy provided by TransCanada. The voting instruction form will name the same persons as the proxy to represent the shareholder at the Meeting. A shareholder has the right to appoint a person (who need not be a shareholder of TransCanada) other than the persons designated in the voting instruction form, to represent the shareholder at the Meeting. To exercise this right, the shareholder should insert the name of the desired representative in the blank space provided in the voting instruction form.  You are asked to complete and return the voting instruction form to Broadridge by mail or facsimile. Alternatively, you can

call Broadridge’s toll-free telephone number or access Broadridge’s internet website to vote your common shares.  Broadridge then tabulates the results of all instructions received and provides appropriate instructions respecting the voting of common shares to be represented at the Meeting. If you receive a voting instruction form from Broadridge, it cannot be used as a proxy to vote common shares directly at the Meeting as the voting instruction form must be returned to Broadridge well in advance of the Meeting in order to have the common shares voted or to appoint an alternative representative to attend at the Meeting in person to vote such common shares.

If you are a beneficial shareholder and wish to vote in person at the Meeting, you should insert your own name in the space provided on the voting instruction form provided to you by your nominee and return the completed form to Broadridge.

Appointing a Proxyholder

A proxyholder is the person you appoint to act on your behalf at the Meeting and to vote your shares.  You may choose anyone to be your proxyholder — the person you choose does not have to be a TransCanada shareholder. If you are a registered shareholder, simply insert the person’s name in the blank space provided on the proxy form, or if you are a beneficial holder, then insert the name of your proxyholder on the voting instruction form. You should ensure that this person is attending the Meeting and is aware that he or she has been appointed to vote your shares. If you do not insert a name in the blank space, then the persons named on the form, being S. Barry Jackson, Harold N. Kvisle or Donald J. DeGrandis, each of whom are directors or officers of TransCanada, will be appointed to act as your proxyholder.

Your appointed proxyholder is authorized to vote and act for you at the Meeting, including any continuation after an adjournment of the Meeting. On the form you can indicate how you want your proxyholder to vote your shares. You may vote FOR or WITHHOLD your vote on the appointment of an auditor and on each proposed nominee for election as director and you may vote FOR or AGAINST the reconfirmation and approval of the amendments to the Stock Option Plan, the reconfirmation and approval of amendments to the Shareholder Rights Plan and the acceptance of TransCanada’s approach to executive compensation.  Alternatively, you can let your proxyholder decide for you.

All common shares represented by properly executed and deposited forms of proxy will be voted or withheld from voting on the matters identified in the Notice of Meeting in accordance with the instructions of shareholders as specified on the forms of proxy or voting instruction forms.

Voting Discretion of Proxyholder

If you give directions on how to vote your shares, your proxyholder must vote your shares according to your instructions. If your proxy form or voting instruction form does not specify how to vote on a particular issue, then your proxyholder can vote your shares as he or she sees fit. If your proxyholder does not attend the Meeting and vote in person, your shares will not be voted.

If you have appointed a person designated by TransCanada to act and vote on your behalf as provided in the enclosed form of proxy and you do not provide any instructions concerning a matter identified in the Notice of Meeting, the common shares represented by such proxy will be voted as follows:

Your proxyholder also has discretionary authority to vote on any amendments that are made to matters identified in the Notice of Meeting or other matters that properly come before the Meeting or any adjourned meeting. At the time of printing this Proxy Circular, management does not know of any matter to come before the Meeting other than the matters referred to in the Notice of Meeting.

Revoking Your Proxy

If you change your mind and want to revoke your proxy, you can do so by signing a written statement (or having your attorney, as authorized in writing, sign a statement) to this effect and delivering it to the Corporate Secretary at the registered office of TransCanada, 450 First Street S.W., Calgary, Alberta, T2P 5H1 at any time up to and including the close of business on the last business day preceding the day of the Meeting or any adjournment thereof or depositing it with the Chair of the Meeting on the day of the Meeting, being Friday, April 30, 2010, or any adjournment thereof, or in any other manner permitted by law.

If you cast your vote by telephone or internet, you may revoke or change your vote by entering the proxy system (telephone or internet) in the same manner and casting another vote no later than 4:30 (Eastern Daylight Time) on Tuesday, April 27, 2010. A later vote cast will supersede any prior vote cast.

FINANCIAL STATEMENTS

The audited consolidated financial statements of TransCanada for the year ended December 31, 2009 and the report of the auditors thereon will be placed before the Meeting.  These audited consolidated financial statements form part of the 2009 Annual Report of TransCanada. Copies of the 2009 Annual Report, in English or French, may be obtained from the Corporate Secretary of TransCanada upon request and will be available at the Meeting.  The full text of the 2009 Annual Report is available on TransCanada’s website at www.transcanada.com.

ELECTION OF DIRECTORS

TransCanada’s articles of incorporation provide for the Board to consist of a minimum of 10 and a maximum of 20 directors. The number of directors presently in office is 13.

The Board has set the number of directors to be elected at the Meeting at 13. The nominees for election as directors of TransCanada are:

The persons proposed for nomination are, in the opinion of the Board, well qualified to act as directors for the ensuing year. Each nominee, with the exception of Mr. Kvisle, because of his role as President and Chief Executive Officer (“CEO”) of TransCanada, has been determined by the Board to be independent within the meaning of Canadian and applicable U.S. securities law, regulation and policy, and applicable stock exchange rules and has established his or her eligibility and willingness to serve as a director if elected. Each director elected will hold office until the next annual meeting or until his or her successor is earlier elected or appointed. The proposed nominees will also be the directors of TransCanada PipeLines Limited (“TCPL”).

The persons named in the form of proxy are either officers or directors of TransCanada; they intend to vote at the Meeting for the election of the nominees whose names are set forth above unless specifically instructed on the form of proxy to withhold such vote.

More information on each of the 13 proposed nominees for election as director is set forth under the heading “Nominees for Election to the Board of Directors”.  This section sets forth whether or not the nominee is independent of TransCanada; age; place of residence; all positions and offices held with TransCanada, if any; present principal occupation; a brief biography, including principal occupations held in the past five years; education; the committees on which each of the directors serve including their attendance at Board and committee meetings; the year from which each has continually served as a director of TransCanada or TCPL prior to the 2003 arrangement whereby TCPL became a wholly-owned subsidiary of TransCanada; a listing of other public board directorships that the nominees for election as director serve as director and any related committees; and the total value of equity at-risk held by each nominee.

APPOINTMENT OF AUDITORS

The Board recommends that KPMG LLP, Chartered Accountants, be appointed as TransCanada’s auditors to hold office until the close of the next annual meeting and that the directors be authorized to fix their remuneration.  Representatives of KPMG LLP will be present at the Meeting, will be given the opportunity to make a statement if they so wish, and will respond to appropriate questions.  The aggregate fees for professional services rendered by KPMG LLP for the TransCanada group of companies for the 2009 and 2008 fiscal years are shown in the table below.

RECONFIRMATION OF AND AMENDMENTS TO THE STOCK OPTION PLAN

In 1995, TCPL established the Key Employee Stock Incentive Plan (1995) (the “1995 Option Plan”). The 1995 Option Plan was subsequently amended, with the approval of the shareholders of that company, on May 19, 1998. As part of the Arrangement with TCPL effective May 15, 2003, a stock option plan (the “Stock Option Plan”) was adopted by TransCanada with substantially the same terms and conditions as the 1995 Option Plan, as amended. The Stock Option Plan was confirmed by the shareholders of TransCanada on April 23, 2004.  On April 27, 2007 the Stock Option Plan was amended and reconfirmed by TransCanada shareholders.  For further details relating to the Stock Option Plan, see “Executive Compensation Tables — Equity Compensation Plan Information — Stock Option Plan”.

During the last fiscal year and up to the date hereof, the Board approved, upon recommendation of the Human Resources Committee, certain amendments to the Stock Option Plan, the effects of which are as follows:

Shareholders will be asked at the Meeting to consider and, if deemed advisable, to approve, by a simple majority of votes cast at the Meeting, a resolution, the text of which is set out in Schedule “A” of this Proxy Circular (the “Stock Option Plan Resolution”), to approve certain amendments to the Stock Option Plan.  If the Stock Option Plan Resolution is not passed by a simple majority of common shares represented at the Meeting, no further grants of options will be possible under the Stock Option Plan, however, it will continue on the same terms as it was the day before the Meeting in respect of options previously granted.

The Board of Directors has approved, subject to shareholder approval, an amendment to increase by 3,500,000 the total number of common shares reserved for issuance under the Stock Option Plan.

When it was established, 10,000,000 common shares were reserved for issuance under the 1995 Option Plan. An additional 15,000,000 common shares were reserved for issuance under the 1995 Option Plan at the time of the merger with NOVA Corporation on July 2, 1998 and an additional 1,000,000 common shares were reserved for issuance at the Company’s Annual and Special meeting of Shareholders held on April 23, 2004.  At the Company’s Annual and Special Meeting of shareholders held on April 27, 2007, an additional 4,500,000 common shares were reserved for issuance.  Subsequent to the 2010 stock option grant made on February 26, 2010, there are currently 2,033,618 common shares reserved for issuance in respect to future awards of options under the Stock Option Plan.

Shareholders are being requested to approve an increase in the number of common shares reserved for issuance under the Stock Option Plan by 3,500,000.  This amount, with the current reserve, is considered a sufficient number of common shares to adequately provide for all option awards for the next three years.  Shareholders will be asked to reconfirm the Stock Option Plan at the Company’s 2013 annual and special meeting of shareholders.

The following table sets forth the number of common shares which may be subject to options granted under the Stock Option Plan, after the proposed amendment, as of February 26, 2010.

The Board of Directors unanimously recommends that shareholders vote FOR the Stock Option Plan Resolution.

CONTINUATION, RATIFICATION, CONFIRMATION AND APPROVAL OF THE SHAREHOLDER RIGHTS PLAN

On December 2, 1994, TCPL implemented its Shareholder Rights Plan (the “Shareholder Rights Plan”). The Shareholder Rights Plan was subsequently amended, with the approval of the shareholders of that company, as of April 7, 1995; May 19, 1998; and April 27, 2001. As part of the Arrangement with TCPL effective May 15, 2003, the Shareholder Rights Plan was adopted by TransCanada with substantially the same terms and conditions as the TCPL Shareholder Rights Plan. TransCanada shareholders ratified, confirmed and approved the continuation of the Shareholders Rights Plan on April 23, 2004.  On April 27, 2007, TransCanada shareholders approved amendments and reconfirmed the Shareholder Rights Plan.

Shareholders will be asked at the Meeting to consider and, if deemed advisable, to approve a resolution, the text of which is set forth in Schedule “B” of this

Proxy Circular (the “Rights Plan Resolution”), to continue, ratify, confirm and approve the Shareholder Rights Plan. For the Shareholder Rights Plan to continue in effect after the Meeting, the Rights Plan Resolution must be passed by a simple majority of common shares represented at the Meeting. If the Rights Plan Resolution is not passed, the Shareholder Rights Plan will terminate. The Board of Directors has determined that the Shareholder Rights Plan continues to be in the best interests of TransCanada and the shareholders.

The Board of Directors unanimously recommends that shareholders vote FOR the Rights Plan Resolution.

In connection with submitting the Shareholder Rights Plan to shareholders for reconfirmation, the Company considered, among other matters, developments in shareholder rights plans since the Shareholder Rights Plan was ratified, confirmed and approved in April 2004 and the terms and conditions of current right plans adopted by the other inter listed, widely-held Canadian public companies.  Based upon this review, the Board of Directors has determined that since April 2007, when the Shareholder Rights Plan was last approved by shareholders, there have been few, if any, material changes to such rights plan design.  On February 22, 2010, the Board resolved to continue, ratify, confirm and approve the Shareholder Rights Plan agreement dated as of April 27, 2007.  If the Shareholder Rights Plan is approved by the shareholders at the Meeting, it will expire at the close of business on the date of the Company’s 2013 annual meeting of shareholders, unless extended by a further vote of the shareholders.  The principal terms of the Shareholder Rights Plan as it is proposed to be continued, ratified, confirmed and approved, including a description of the principle terms of the plan, are summarized below.

This summary is qualified in its entirety by reference to the full text of the Shareholder Rights Plan agreement, including the definitions therein.  Any shareholder or interested party can obtain a copy of the amended rights agreement by contacting the Corporate Secretary of the Company or from TransCanada’s website at www.transcanada.com.

Objectives

The primary objective of the Shareholder Rights Plan is to provide the Board of Directors with sufficient time to explore and develop alternatives for maximizing shareholder value if a take-over bid is made for TransCanada and to provide every shareholder with an equal opportunity to participate in such a bid. The Shareholder Rights Plan encourages a potential acquiror to proceed either by way of a Permitted Bid (as defined in the Shareholder Rights Plan agreement), which requires the take-over bid to satisfy certain minimum standards designed to promote fairness, or with the concurrence of the Board.

Effective Date

The effective date of the Shareholder Rights Plan is April 27, 2007.

Term

The Shareholder Rights Plan expires at the close of business on the date of the 2010 annual meeting of shareholders of TransCanada.  If the Shareholder Rights Plan is approved by the shareholders at the Meeting, it will expire at the close of business on the date of the Company’s 2013 annual meeting of shareholders, unless extended by a further vote of the shareholders.

Issue of Rights

On May 15, 2003, one right (a “TransCanada Right”) was issued and attached to each common share outstanding and attached to each common share subsequently issued.

TransCanada Rights Exercise Privilege

The TransCanada Rights will separate from the common shares and will be exercisable ten trading days (the “Separation Time”) after a person has acquired, or commences a take-over bid to acquire, 20% or more of the shares, other than by an acquisition pursuant to a take-over bid permitted by the Shareholder Rights Plan (a “Permitted Bid”).  Prior to a flip-in event (as described below), each TransCanada Right entitles the registered holder thereof to purchase from the Company one common share at the exercise price equal to three times the market price of a common share, subject to adjustments and anti-dilution provisions (the “Exercise Price”).  The beneficial acquisition by any person (an “Acquiring Person”) of 20% or more of the common shares, other than by way of a Permitted Bid, is referred to as a “Flip-in Event”. Any TransCanada Rights held by an Acquiring Person will become void upon the occurrence of a Flip-in Event.  Ten trading days after the occurrence of the Flip-in Event, each TransCanada Right (other than those held by the Acquiring Person), will permit registered holders to receive, upon payment of the Exercise Price, the number of common shares with an aggregate market price equal to twice the Exercise Price.

The issue of the TransCanada Rights is not initially dilutive. Upon a Flip-in Event occurring and the TransCanada Rights separating from the common shares, reported earnings per share on a fully diluted or non-diluted basis may be affected. Holders of TransCanada Rights not exercising their TransCanada Rights upon the occurrence of a Flip-in Event may suffer substantial dilution.

Lock-up Agreement

A bidder may enter into lock-up agreements with TransCanada’s shareholders (“Locked-up Persons”) whereby such shareholders agree to tender their common shares to the take-over bid (the “Subject Bid”) without a Flip-in Event (as referred to above) occurring.  Any such agreement must include a provision that either permits the Locked-up Person to withdraw the common shares to tender to another take-over or to support another transaction that will provide greater value to the shareholder than the Subject Bid by containing an offering price or number of securities that exceeds the offering price or the number of securities contained in the Subject Bid by at least 7% (or by another specified amount in the Subject Bid which must be less than 7%).  For greater certainty, a Lock-up Agreement may contain a right of first refusal or require a period of delay (or other similar limitation) to give a bidder an opportunity to match a higher price or the number of securities in another transaction as long as the shareholder can accept another bid or tender to another transaction.

The Shareholder Rights Plan requires that any Lock-up Agreement be made available to TransCanada and the public and also provides that under a Lock-up Agreement no “break up” fees, “top up” fees, penalties, expenses reimbursement or other amounts that exceed in aggregate the greater of: (i) 2½% of the value payable under the Subject Bid; and (ii) 50% of the amount by which the value received by a Locked-up Person under another take-over bid or transaction exceeds what such Locked-up Person would have received under the Subject Bid; can be payable by such Locked-up Person if the Locked-up Person fails to deposit or tender common shares to the Subject Bid or withdraws common shares previously tendered thereto in order to deposit such common shares to another takeover bid or support another transaction.

Certificates and Transferability

Prior to the Separation Time, the TransCanada Rights are evidenced by a legend imprinted on certificates for the common shares issued from and after the Effective Date and are not to be transferable separately from the common shares. From and after the Separation Time, the TransCanada Rights will be evidenced by TransCanada Rights certificates which will be transferable and traded separately from the common shares.

Permitted Bid Requirements

The requirements for a Permitted Bid include the following:

The Shareholder Rights Plan allows for a competing Permitted Bid (a “Competing Permitted Bid”) to be made while a Permitted Bid is in existence. A Competing Permitted Bid must satisfy all the requirements of a Permitted Bid except that it may expire on the same date as the Permitted Bid, subject to the requirement that it be outstanding for a minimum period of 35 days.

Waiver

The Board of Directors, acting in good faith, may, prior to the occurrence of a Flip-in Event, waive the application of the Shareholder Rights Plan to a particular Flip-in Event (an “Exempt Acquisition”) where the take-over bid is made by a take-over bid circular to all holders of common shares. Where the Board exercises the waiver power for one take-over bid, the waiver will also apply to any other take-over bid for TransCanada made by a take-over bid circular to all holders of common shares prior to the expiry of any other bid for which the Shareholder Rights Plan has been waived.

Pursuant to the amended agreement, the Board of Directors may also waive the application of the Shareholder Rights Plan if the Acquiring Person reduces their beneficial ownership to less than 20% of all outstanding common shares.

Redemption

The Board of Directors, with the approval of a majority vote of the votes cast by shareholders (or the holders of TransCanada Rights if the Separation Time has occurred) voting in person and by proxy, at a meeting duly called for that purpose, may redeem the TransCanada Rights at $0.00001 per TransCanada Right. TransCanada Rights shall also be redeemed by the Board without such approval following completion of a Permitted Bid, Competing Permitted Bid or Exempt Acquisition.

Amendment

The Board of Directors may amend the Shareholder Rights Plan with the approval of a majority vote of the votes cast by shareholders (or the holders of TransCanada Rights if the Separation Time has occurred) voting in person and by proxy at a meeting duly called for that purpose.  The directors may, without such approval, correct clerical or typographical errors and, subject to approval as noted above at the next meeting of the shareholders (or holders of TransCanada Rights, as the case may be), may make amendments to the Shareholder Rights Plan to maintain its validity due to changes in applicable legislation.

Board of Directors

The Shareholder Rights Plan will not detract from or lessen the duty of the Board of Directors to act honestly and in good faith with a view to the best interests of TransCanada. The Board, when a Permitted Bid is made, will continue to have the duty and power to take such actions and make such recommendations to shareholders as are considered appropriate.

Exemptions for Institutional Investors

Generally, investment managers (for client accounts), trust companies (acting in their capacities as trustees and administrators), statutory bodies whose business includes the management of funds and administrators or trustees of registered pension plans or funds (as well as the pension plans or funds) acquiring greater than 20% of the common shares are exempted from triggering a Flip-in Event, provided that they are not making, or are not part of a group making, a take-over bid.  Included in this exemption are the managers or trustees of certain mutual funds as well as the mutual fund itself.

ADVISORY VOTE ON EXECUTIVE COMPENSATION

In order to ensure an appropriate level of director accountability to the shareholders of the Company for their executive compensation decisions, the Board of Directors has determined that a shareholder advisory vote on executive compensation, commonly known as “Say on Pay”, would be beneficial.

Shareholders will be asked at the Meeting to consider and, if deemed advisable, to approve, on an advisory basis, a resolution, the text of which is set out in Schedule “C” of this Proxy Circular, to accept TransCanada’s approach to executive compensation as set forth in the section entitled “Compensation Discussion and Analysis” in this Proxy Circular (the “Advisory Vote on Executive Compensation Resolution”).

The Board of Directors unanimously recommends that shareholders vote FOR the Advisory Vote on Executive Compensation Resolution.

As the vote will be an advisory vote, the results will not be binding upon the Board of Directors. However, the Board of Directors will take the result of the vote into account, as appropriate, when considering future compensation policies, procedures and decisions.  The Company will disclose the results of the shareholder advisory vote as a part of its report on voting results for the meeting.

SHAREHOLDER PROPOSALS

There were no Shareholder proposals received in relation to the Meeting.

Pursuant to Canadian law, shareholder proposals to be considered for inclusion in the management proxy circular for the 2011 annual meeting of holders of common shares must be received by the Corporate Secretary of TransCanada on or before the close of business on November 24, 2010.

INTERLOCKING DIRECTORSHIPS

OVERALL MEETING ATTENDANCE

Attendance at the Board and Committee meetings for each director in 2009 is set forth above in the individual director’s biography.  The table below indicates overall meeting attendance by directors in 2009.

DIRECTOR TENURE

The following table indicates the number of years the nominees for election as director have dedicated to the Corporation’s Board.

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 and receivables from certain of TransCanada’s subsidiaries, 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.

TransCanada’s director compensation practices are designed to reflect the size and complexity of TransCanada and to reinforce the emphasis placed on shareholder value by linking a significant portion of directors’ compensation to the value of common shares.  As a result, directors’ compensation consists of annual retainers and meeting fees paid in cash and in equity-based compensation known as deferred share units (“DSUs”).

The Governance Committee assesses the market competitiveness of TransCanada’s director compensation on an annual basis against publicly traded autonomous Canadian companies in the Comparator Group (as defined under the heading “Compensation Discussion and Analysis”) and a general industry sample of Canadian companies, using an analysis provided by an outside consultant.  Its goal is to provide total compensation to directors that is generally targeted at the median of TransCanada’s peers in both level and form in order to attract and retain qualified individuals.  This goal is reflected in the current compensation paid to directors.  The compensation philosophy for directors’ compensation is different than that for the executive officers discussed under the heading “Compensation Discussion and Analysis” in that it is not directly based on the performance of the Company.

RETAINERS AND FEES PAID TO DIRECTORS

Annual board and committee retainers are paid to each director who is not an employee of TransCanada in quarterly installments, in arrears, and are pro-rated from the date of the director’s appointment to the Board and the relevant committees.  Each committee chair is entitled to claim a per diem for time spent on committee activities outside of the committee meetings.  TransCanada 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.  The retainers and fees paid to non-employee directors in 2009 are set forth in the following table.  Directors who are U.S. residents are paid the same amounts as outlined below in U.S. dollars.  There were no changes to directors’ fees in 2009.

Directors are entitled to direct all or a portion of their cash retainers, meeting fees and travel fees to be paid in DSUs.  In 2009, Mr. Benson, Mr. Burney, Dr. Draper and Mr. Hawkins directed all of their retainers, meeting fees and travel fees to be paid in DSUs.  Ms. Gauthier directed her Committee retainers, Committee meeting fees and travel fees to be paid in DSUs.  Mr. MacNaughton directed his Board and Committee retainers, Board meeting fees and travel fees to be paid in DSUs.  Mr. O’Brien directed his Board retainers to be paid in DSUs.  In addition, Mr. Jackson directed the cash portion of his Chair retainer as well as his Board Chair meeting fee and travel fees to be paid in DSUs. For further information on the plan for DSUs, see the description under the heading “Share Unit Plan for Non-Employee Directors” below.

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 (other than Mr. Kvisle who is subject to executive share ownership guidelines) 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 portion of their Board retainer. 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 directing all or a portion of their retainer fees, attendance fees and travel fees into DSUs as described under the heading “Share Unit Plan for Non-Employee Directors” below.  Should a director’s shareholdings fall below the minimum threshold at any time after having met such threshold due to subsequent share price fluctuations, the director is expected to ensure he or she re-attains the minimum threshold within a reasonable amount of time as determined and reviewed by the Governance Committee.

As of February 22, 2010, all of the directors have achieved the minimum share ownership requirement other than Mr. Stephens who has until 2012 (five years from the date he became a director) to achieve the minimum share ownership requirement.

SHARE UNIT PLAN FOR NON-EMPLOYEE DIRECTORS

The Share Unit Plan for Non-Employee Directors (the “DSU Plan”) was established in 1998.  Pursuant to the DSU Plan, Board members are permitted to elect to receive in DSUs any portion of their retainers and meeting fees (including travel fees) regularly paid in cash.  The DSU Plan also allows the Governance Committee in its discretion, to grant units as additional compensation for directors.

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.  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 DSUs for cash or common shares at their option.  U.S. directors may only redeem DSUs for cash.

2009 RETAINERS AND FEES

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 2009 as at the date of the grant, unless otherwise stated. Mr. Kvisle, as an employee of TransCanada, receives no cash fees or DSUs as a director.
