In 1801, the Hudson's Bay Company established a wintering post called Big Fall or Great Fall in the area, reporting to Osnaburgh House. It operated until 1805, and again from at least 1816 to 1821.

In 1865, the outpost was reestablished by William McKay, and was called Grand Rapid, named after the rapids on the Berens River. It was supplied from York Factory until 1871, and then from Winnipeg via Lake Winnipeg and the Berens River. In 1888, it became a full trading post and renamed to Little Grand Rapids in order to distinguish it from Grand Rapids post on the west side of Lake Winnipeg.

In the early 20th century, the outposts at Pikangikum, Deer Lake, and Poplar River were operated from the Little Grand Rapids post. In 1921, the last York boat was used to supply the post from Berens River. In 1941, a lightning fire destroyed all the buildings and the post was rebuilt half a mile to the east.

In 1959, the post became part of the HBC Northern Stores Department, which was divested by HBC in 1987 to The North West Company, which still operates a Northern Store in Little Grand Rapids.
