John Thomas (or Thompson,[1] c. 1751 – June 9, 1822) was a Canadian fur trader who played a significant role in the exploration and establishment of posts by the Hudson's Bay Company (HBC) in North America.
Born in London, England, Thomas later moved to modern-day Canada and married Margaret, an Indigenous Canadian woman, with whom he had nine children.
To counter this, the HBC told its officers to seek new trading opportunities in the uncharted regions of Canada, and set up new posts.
He described the place and its inhabitants in detail, and conducted further explorations in the Moose Factory area, travelling east and west to lay the groundwork for future HBC posts in the region.
The scarcity of local provisions necessitated frequent returns to Wapiscogamy House, prompting Thomas to delegate the management of Missinaibi to his servants.
