The Robert Simpson Company, or Simpsons (Simpson's until 1972), was a Canadian department store chain, founded by Robert Simpson in 1872. Robert Simpson had no male heir and on his death in 1897, the business was sold to a consortium of investors made up of Albert Ernest Ames, Joseph Flavelle and Harris Henry Fudger. The chain was eventually bought by the Hudson's Bay Company, and the Simpsons brand is no longer in use.
The Simpsons store in downtown Toronto included one of Toronto's most famous and exclusive restaurants, the Arcadian Court, which opened in 1929. The store was acquired by Hudson's Bay Company in 1978, and the Arcadian Court is still in operation today. Throughout its history Simpsons was the traditional carriage trade department store in Toronto--competing with the rival T. Eaton Co.
In 1972, Simpsons and Simpsons-Sears Limited agreed to end the 25-mile restriction, and permit Simpsons and Simpsons-Sears Limited stores anywhere. In 1973, when Simpsons-Sears opened a store in the city of Mississauga, just west of Toronto, the company decided to use only the "Sears" name in order to prevent confusion with Simpsons stores operating in Toronto. Through 1973 and 1974, the remaining Simpsons-Sears stores and the catalogue operation were converted to the "Sears" name, although the legal partnership continued under the Simpsons-Sears name.
In the early 1980s, the Hudson Bay's Company converted three Simpsons stores into Bay stores. On the other hand, an existing Bay store was converted to a Simpsons store around the same time.
In 1989 the flagship downtown Toronto Simpsons store completed a $30 million facelift with a relaunch known as the "Miracle on Queen Street", including a cosmetics area reputed to have been the largest in the world. The basement featured the addition of a gourmet food hall like that at Macy's in Herald Square in New York City or Harrods in London, and the St. Regis Room was expanded. Upscale shops such as Alfred Dunhill of London were included. The downtown store remains the largest department store in Canada.
The Hudson's Bay Company attempted to run Simpsons as a more upscale brand than its main brand The Bay, but was unsuccessful. The Simpsons operations were merged with The Bay in 1989 in the province of Quebec, and 1991 in the rest of the country. Since then, all of the stores have either been converted to The Bay or been closed, and the Simpsons name is no longer used.
The Canadian Intellectual Property Office database reports that the trademark to the name "Simpsons" is now owned by Sears Canada. It was purchased from the Hudson's Bay Company in 2001, some ten years after the name was officially retired.
While operated by Simpsons, the St. Regis Room, offered some of the most exclusive fashion collections in Canada. Dior, Oscar de la Renta, Yves Saint Laurent, Claude Montana, Courreges, and many others were featured in this luxury department.

Simpsons is seen and mentioned in the 1988 movie Short Circuit 2 (although the store that was referred to as Simpsons was actually the Eaton's store).
