Retail giant Wal-Mart Stores made its blanket coverage of North America complete with the 1994 acquisition of the 122-store Woolco division of Woolworth Canada. Like Wal-Mart de México, its sister company south of the US-Mexico border, Wal-Mart Canada has since grown into a major retail force in its home country with about 395 stores, more than half of which are supercenters (which sell groceries and general merchandise under one huge roof). Wal-Mart Canada's discount stores offer a vast selection of products, including apparel, household goods, hardware, toys, sporting goods, health and beauty aids, food and other merchandise. In-store services include banking, vision centers, and tire and auto centers.
