The Robert Simpson Company Limited, commonly known as Simpson's until 1972, then as Simpsons, and in Quebec sometimes as Simpson, was a Canadian department store chain that had its earliest roots in a store opened in 1858 by Robert Simpson. In 1952 Simpson's started a 50-50 joint venture in Canada named Simpsons-Sears Limited (later Sears Canada) with Sears, Roebuck, the American retailer. Simpsons-Sears stores remained distinct from the Simpson's stores and the parent companies' agreement included language to keep them from competing too directly with each other.
