AMENDMENT EXPLANATORY NOTICE

On March 22, 2011, Videotron Ltd. (Videotron) filed its annual report on Form 20-F for the year ended
December 31, 2010 (the Annual Report). This Amendment No. 1 (this Amendment) on Form 20-F/A to our Annual Report is being filed solely for the purpose of correction of a clerical error in the text of the audit
report of Ernst & Young LLP included in the Annual Report. Such audit report is hereby replaced in its entirety.

Therefore, this Amendment consists of a cover page, this explanatory notice, the revised audit report, a revised list of Exhibits (Item 19 of Part III) and a signature page.

This Amendment speaks as of the date of the initial filing of the Annual Report. Other than as described above, this
Amendment does not, and does not purport to, amend, update or restate any other information or disclosure included in the Annual Report and does not, and does not purport to, reflect any events that have occurred after the date of the initial filing
of the Annual Report. As a result, our Annual Report on Form 20-F for the fiscal year ended December 31, 2010, as amended by this Amendment, continues to speak as of the initial filing date of the Annual Report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and to the Shareholder of Videotron Ltd.

We
have audited the accompanying consolidated balance sheets of Videotron Ltd. as of December 31, 2010 and 2009, and the related consolidated statements of income, comprehensive income, shareholders equity and cash flows for the years ended
December 31, 2010, 2009 and 2008. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. We were not engaged to perform an audit of the Companys internal control
over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Videotron Ltd. as of December 31, 2010 and 2009, and the consolidated results of their operations and their cash flows for the years ended December 31, 2010, 2009 and 2008, in conformity with Canadian Generally
Accepted Accounting Principles.
