The Bay Queen Street Store Department stores revolutionized shopping in the late nineteenth century by offering selection, low prices and money-back guarantees. In 1895, Robert Simpson commissioned architect Edmund Burke to design his new department store at the southwest corner of Yonge and Queen Streets. It was the first building in Canada with a load-bearing metal frame and a façade clearly patterned on this internal structure. By 1969, Simpson's department store had been enlarged six times and occupied two city blocks between Yonge, Queen, Bay and Richmond Streets. Canada's oldest corporation and largest department store retailer, Hudson's Bay Company, acquired the building in 1978. A Bay store since 1991, it remains one of Canada's great shopping landmarks.
