"Additional Canadian Guarantors") in connection with the Company's offer to

"Exchange Notes") for up to U.S.$200,000,000.00 of its outstanding 7-5/8% Series
A Senior Notes due 2013 (the "Initial Notes"). This opinion is being delivered
to you for filing as an exhibit to the Registration Statement on Form F-4 filed

"Registration Statement") pursuant to the United States Securities Act of 1933,
as amended (the "Securities Act"), relating to the registration of the Exchange
Notes (and the related Guarantee of the Guarantors (the "Guarantees")) under the
Securities Act. The Initial Notes were issued, and the Exchange Notes will be
issued, pursuant to an Indenture, dated as of April 3, 2003 (the "Indenture"),
among the Company, the Guarantors and The Bank of New York, as Trustee.

     respective jurisdictions of organization, and there are no restrictions on
     the corporate power and capacity of the Company or any of the Canadian
     Guarantors to execute, deliver and perform their respective obligations
     under the Exchange Notes, the Indenture and the Guarantee, to the extent a
     party thereto.

2.   The Exchange Notes have been duly authorized and, when issued, executed and
     authenticated in accordance with the provisions of the Indenture and
     delivered in exchange for the Initial Notes, will be duly executed and
     delivered by the Company.

     Guarantor and has been duly executed by the Company and each Canadian

     thereunder and the enforcement of such obligations do not violate any
     provision of any federal or provincial law, statute, rule or regulation
     presently in effect in the Province of Ontario.

2.   The corporate and partnership records and minute books of the Company and
     each of the Canadian Guarantors provided to Counsel (as indicated on
     Schedule A hereto) in connection with the offering of the Initial Notes on
