Dominion Stores was once a national chain of
supermarkets in
Canada, which was known as the Dominion of Canada at the time of the company's founding. The chain was founded in 1919 in Ontario and was later acquired by the
Argus Corporation. It was later sold to
The Great Atlantic and Pacific Tea Company (A&P), which restricted the chain to the
Greater Toronto Area. Stores outside Ontario were converted to the A&P banner or sold to third parties. A&P's Canadian division was later acquired by
Metro Inc., which rebranded the remaining Dominion stores to its namesake banner in 2008.
