is a chain of over 800 dollar stores across Canada. The company is headquartered in Montreal and, since 2009, is Canada's largest retailer of items for three dollars or less. The first Dollarama store was created at the shopping centre "Les promenades du St-Laurent" in Matane. Dollarama now has stores in every province of Canada, with Ontario having the most stores.
Virtually all the Dollarama stores are located where there once were BiWay stores, a defunct chain of Canadian discount retail operations intended to compete with retailers such as Zellers, Kmart and Wal-Mart, which closed after a series of dubious financial transactions involving a new owner of the parent operation.
