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.

Sears, Roebuck and Co., commonly known as Sears, is an American chain of department stores founded in 1892 by Richard Warren Sears and Alvah Curtis Roebuck and reincorporated in 1906 by Richard Sears and Julius Rosenwald, with what began as a mail ordering catalog company migrating to opening retail locations in 1925, the first in Chicago. In 2005, the company was bought by the management of the American big box discount chain Kmart, which upon completion of the merger, formed Sears Holdings. Through the 1980s, Sears was the largest retailer in the United States. In 2018, it was the 31st-largest. After several years of declining sales, Sears's parent company filed for Chapter 11 bankruptcy on October 15, 2018. It announced on January 16, 2019, that it had won its bankruptcy auction, and that a reduced number of 425 stores would remain open, including 223 Sears stores.
