The Northwest region of Canada was not originally part of the Province of Canada or Dominion of Canada. It was occupied by First Nations peoples and fur traders from the Hudson's Bay Company and Northwest Company. The Hudson's Bay Company had been granted trading rights to Rupert's Land, an area encompassing 1/3 of modern Canada, including the Northwest region. Both companies built trading posts and encouraged Indigenous trappers to bring furs for trade, with the Northwest Company shipping furs from Montreal and the Hudson's Bay Company shipping from ports on Hudson Bay. First Nations peoples played a key role in the fur trade by hunting and trapping animals for their pelts and trading at the company posts.
