This statement constitutes AN AMENDMENT to the statement previously filed on Schedule 13D by Caisse de dépôt et placement du Québec.

Item 1 - Security and Issuer

This statement is made with respect to the Common Shares (the "Shares") of Domtar inc. ("Domtar"), a Canadian corporation, the address of the principal executive offices of which is 395, boul. de Maisonneuve Ouest, Montréal (Québec) H3A 1L6.

Item 2 - Identity and Background

This statement is filed by the Caisse de dépôt et placement du Québec ("Caisse"). Caisse is a legal person without share capital and a mandatary of the State of the Province de Québec, created by a special act of the Legislature of the Province de Québec. The principal business of Caisse is to receive on deposit and manage funds deposited by agencies and instrumentalities of the Province de Québec.

The address of Caisse's principal business and principal office is 1000, place Jean-Paul-Riopelle, Montréal, Québec, H2Z 2B3. The names of the directors and executive officers of Caisse, their business addresses, their present principal occupation or employment, and the name, principal business and address of any corporation or other organization in which such employment is conducted other than Caisse are set forth in Exhibit A, attached hereto.

Each of the directors and executive officers named in Exhibit A is a Canadian citizen, except Mr. John T. Wall who is an American citizen.

Neither Caisse nor any of the individuals listed in Exhibit A has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or was or is subject to a judgment, decree or final order, enjoining future violations of, or prohibiting or mandating activities subject to, United States federal or state securities laws or finding any violation with respect to such laws as a result of a civil proceeding of a judicial or administrative body of competent jurisdiction.

Item 3 - Source and Amount of Funds or Other Consideration

Caisse sold 402,283 Shares for Can. $6,172,189.

Item 4 - Purpose of Transaction

The Shares reported on herein were purchased or sold for purposes of investment. Caisse intends to review its investment in Domtar periodically, and may, depending on relevant economic and financial market conditions and matters relating to Domtar, either acquire additional Shares or sell Shares. Any subsequent acquisition of such Shares by Caisse may be made by way of market purchases, private agreements or otherwise.

Caisse has no plan or proposal which relates to or would result in a change in Domtar business, corporate structure, board of directors, management, capitalization, dividend policy, charter or bylaws or to the registration of Domtar Shares or their listing on securities exchanges.

Item 5 - Interest in Securities of Issuer

a-b) With recent transactions, Caisse now beneficially owns 33,042,522 Shares, including 30,329,757 Shares owned by Capital d'Amérique CDPQ inc., wholly owned subsidiary by the Caisse. Therefore, the Shares presently owned by Caisse and Capital d'Amérique CDPQ inc. represent 14.45% of the Shares outstanding pursuant to most recently available filing with the Commission.

In addition, as mentioned on our Amendment no. 9 to the statement filed on Schedule 13D, following an agreement between Caisse and Société Générale de Financement ("SGF") dated June 14, 1985, where the parties agreed to vote their Shares to obtain proportionate board representation, Caisse may be deemed to beneficially own 18,170,249 Shares owned by SGF, for an aggregate of 51,212,771 Shares but Caisse declares it does not beneficially own those 18,170,249 Shares. The percentage of the class of Shares held by Caisse is 14.45% (22.43% including the Shares owned by SGF)

Caisse also owns Can.$80,000,000 of George Weston Limited Debentures (expiring June 30, 2023). If the Debentures are issued and converted in respect of other specific conditions of the Debentures, those Debentures would represent 7,619,048 Shares of Domtar inc. (18.75% of the Shares issued and outstanding on a partially diluted basis).

The beneficial ownership of Domtar by the individuals named in item 2 is set forth to the best of Caisse's knowledge in Exhibit C attached, when applicable.

Caisse has the power to vote and to dispose of the Shares it owns.

c) The dates and amounts of all transactions in the Shares that were effected by the Caisse during the past sixty days are set forth in Exhibit B attached hereto.

d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares of Domtar listed in response to this item.

e) N/A

Item 6 - Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Caisse and, to the best of its knowledge, the individuals named in Item 2, have no contracts, arrangements, understandings or relationships with respect to any securities of Domtar.

Item 7 - Material to be Filed as Exhibits

Exhibit A: List of Executive Officers and Directors of Caisse
Exhibit B: List of Executive Officers and Directors of Capital d'Amérique CDPQ inc.
Exhibit C: Table of Dates, Number of Shares Sold and Price per Share of Sales

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
