Long Lake Posts
In 1814 the Hudson's Bay Company set up a trading post on Long Lake about 3 km southwest of here, close to one established prior to 1800 by the North West Company. The latter had been intercepting trade which would otherwise have gone to Henley House, an H.B.C. post on the Albany River some 225 km to the northeast. The two local posts continued in bitter competition until the union of the rival companies in 1821. In subsequent years Long Lake House was a relay post on the winter "express route" between Red River and Moose Factory. The post was moved in 1921 to its present location in Longlac.
