TVA AND SUN MEDIA ENTER INTO PURCHASE AGREEMENT
WITH CHUM FOR ACQUISITION OF TORONTO 1

Montréal, August 20, 2004. TVA Group Inc. (TSX:TVA.b) and Sun Media Corporation, both subsidiaries of Quebecor Media Inc., announced today that they have entered into a definitive purchase agreement with CHUM Limited to acquire the newly launched Toronto 1 station in Toronto which CHUM is currently in the process of acquiring from Craig Media Inc. Closing of the transaction remains subject to certain conditions, including the obtaining of all regulatory approvals and the closing of the transaction between CHUM and Craig Media announced on April 12, 2004.

        The purchase price of the acquisition is $46 million. TVA will pay $34.5 million in cash at closing for a 75% interest in Toronto 1. Sun will pay $3.5 million in cash at closing and deliver to CHUM its 29.9% interest in CP24, a 24-hour local news channel in Toronto, for the remaining 25% of Toronto 1. Management of TVA and Sun Media anticipate that the transaction will close in the second quarter of 2005 shortly after all the required regulatory approvals have been obtained in respect of CHUM's acquisition of all the shares of Craig Media Inc., the current owner of Toronto 1, and the subsequent sale of Toronto 1 to TVA and Sun Media. TVA and Sun Media have agreed to file an application for the transfer of ownership and control of Toronto 1 with the CRTC by September 2, 2004.

        Serge Gouin, the President and Chief Executive Officer of TVA and Quebecor Media, said "This transaction allows us to secure a strategic positioning in Canada's largest market by combining TVA's expertise in the management of a premier television operation with Quebecor's ability to turn-around businesses. The Toronto advertising market is the 5^th largest in North America and, as such, it presents a significant growth opportunity for TVA and an important step in leveraging all of our media assets in English-speaking Canada."

        As for Pierre Francoeur, President and Chief Executive Officer of Sun Media, he said "Toronto 1 will be a natural fit with our newspapers and will provide numerous opportunities for promotional synergies which will be mutually beneficial. Our expertise in this area has been clearly demonstrated and will allow us to quickly generate positive results for our organization."
