As per Wikipedia, Montagnais (meaning Mountaineers in French) may refer to a subdivision of the Innu (Innu are not Inuit) people of Canada.

The Innu are the Aboriginal inhabitants of an area in Canada they refer to as Nitassinan (“Our Land”), which comprises most of the northeastern portion of the province of Quebec and some western portions of Labrador. Their population in 2003 included about 18,000 people, of which around 14,000 lived in Quebec, under 3000 in Labrador, and the rest outside their traditional territory.

The French speaking missionaries to the Northwest of the Red River Colony referred to the Dene Chipewyan people as Montagnais in their documents written in French. Montagnais (in French) therefore has often been mistakenly translated to Montagnais (in English) which now refers to the Montagnais (Innu language) of northern Quebec and not the Dene (Chipewyan people).
