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.

Sears Canada Inc. was a publicly-traded Canadian company affiliated with the American-based Sears department store chain. In operation from 1952 until January 14, 2018, and headquartered in Toronto, Ontario, the company began as Simpsons-Sears—a joint venture between the Canadian Simpsons department store chain and the American Sears chain—which operated a national mail order business and co-branded Simpsons-Sears stores modelled after those of Sears in the U.S. After the Hudson's Bay Company purchased Simpsons in 1978, the joint venture was dismantled and Hudson's Bay sold its shares in the joint venture to Sears; with Sears now fully owning the company, it was renamed Sears Canada Inc. in 1984. In 1999, Sears Canada acquired the remaining assets and locations of the historic Canadian chain Eaton's. From 2014, Sears Holdings owned a 10% share in the company. ESL Investments was the largest shareholder of Sears Canada.
