The Hudson's Bay Company (abbreviated HBC and colloquially Hudson's Bay) is a Canadian holding company of department stores and commercial property. It is the oldest corporation in North America, founded in 1670 and liquidated in 2025. It was headquartered at the Simpson Tower in Toronto.
The founding royal charter, issued by King Charles II, granted the company the right of "sole trade and commerce" over the Rupert's Land territory, the borders of which were based on the Hudson Bay drainage basin. It controlled the fur trade throughout English and later British North America, and was its de facto government until it relinquished control of the land to Canada in 1869. The company then diversifed with the ownership and operation of several retail businesses throughout the latter country.
