In 2005, A&P Canada Co. operated 135 stores under the Dominion, A&P, Ultra Food & Drug and the Barn Markets banners, and 101 Food Basics stores. It employed over 30,000 employees in Ontario.
On July 19, 2005, Metro Inc. announced that it had reached an agreement with the Great Atlantic & Pacific Tea Company, Inc. and its subsidiary, A&P Luxembourg S.à.r.l., to acquire all of the issued and outstanding common shares of A&P Canada, for an acquisition price of $1.7 billion, consisting of $1.2 billion in cash and $500 million in the form of treasury shares of Metro. The sale was completed on August 15, 2005.
On August 7, 2008, Metro announced it would invest $200 million consolidating the company's conventional food stores under the Metro banner. Over a period of 15 months, all Dominion, A&P, Loeb, the Barn and Ultra banners were converted to the Metro name. Food Basics stores were not directly affected because they compete in the discount food segment, but did see A&P's "Master Choice" store brand replaced with Métro's « Sélection » and « Irresistibles » brands.
