RE: US$175,000,000 6 3/8% Senior Notes due December 15, 2015

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

    In connection with the registration under the United States Securities Act
of 1933, as amended (the "Securities Act") of (a) US$175,000,000 principal
amount of 6 3/8% Senior Notes due December 15, 2015 (the "Notes") of Videotron
Ltee, a company incorporated under and governed by the laws of the Province of
Quebec (the "Company"), to be issued in exchange for the Company's outstanding
6 3/8% Senior Notes due December 15, 2015 pursuant to an indenture dated
September 16, 2005 (the "Indenture") among the Company, the subsidiaries of the
Company listed on Schedule I hereto (collectively, the "Guarantors") and Wells
Fargo Bank, National Association as trustee, and (b) the guarantees
(the "Guarantees") of each of the Guarantors endorsed upon the Notes, we as your
special counsel, have examined such corporate records, certificates and other
documents, and such questions of law as we have considered necessary or
appropriate for the purposes of the opinion expressed below. We have also relied
as to certain factual matters on information obtained from officers of the
Company and the Guarantors, public officials and other sources believed by us to
be responsible.

    Upon the basis of such examination, we advise you that, in our opinion, when
the Company's Registration Statement on Form F-4 relating to the Notes and the
Guarantees (the "Registration Statement") has become effective under the
Securities Act, the terms of the Notes and the Guarantees and of their issuance
have been duly established in conformity with the Indenture so as not to violate
any applicable law or result in a default under or breach of any agreement or
instrument binding upon the Company or the Guarantors, respectively, and so as
to comply with any requirement or restriction imposed by any court or
governmental body having jurisdiction over the Company and the Guarantors,
respectively, and the Notes and Guarantees have been duly executed, delivered
and authenticated in accordance with the terms of the Indenture and issued as
contemplated in the Registration Statement, the Notes and the Guarantees will
constitute valid and legally binding obligations of the Company and the
Guarantors, respectively, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

    The foregoing opinion is limited to the federal laws of the United States,
the laws of the State of New York, and the laws of the Province of Quebec and
the federal laws of Canada applicable therein, all as of the date hereof, and we
are expressing no opinion as to the effect of the laws of any other
jurisdiction.

    We have prepared the discussion included in the prospectus forming part of
the Registration Statement under the caption "Certain Tax
Considerations -- Canadian Material Federal Income Tax Considerations for
Non-Residents of Canada". The discussion under that caption is our opinion of
the main Canadian federal income tax consequences applicable to Non-Resident
Holders, as defined therein, subject to the conditions, limitations and
assumptions described therein.

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to this firm under the headings,
"Enforceability of Civil Liabilities", "Legal Matters", "Description of the
Notes -- Enforceability of Judgments" and "Certain Tax
Considerations -- Canadian Material Federal Income Tax Considerations for
Non-Residents of Canada" in the prospectus included in the Registration
Statement. In giving the foregoing consent, we do not thereby admit that we are
in the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the United States Securities and
Exchange Commission thereunder.

Yours truly,

/s/ OGILVY RENAULT LLP
