Indigenous peoples in Canada [SEP] Introduction
Indigenous Canadians (also known as Aboriginal Canadians, Native Canadians or First Peoples) are the Indigenous peoples within the boundaries of Canada. They comprise the First Nations, Inuit and Métis. Although "Indian" is a term still commonly used in legal documents, the descriptors "Indian" and "Eskimo" have somewhat fallen into disuse in Canada, and some consider them to be pejorative. "Aboriginal" as a collective noun is a specific term of art used in some legal documents, including the "Constitution Act, 1982", though in some circles that word is also falling into disfavour. Old Crow Flats and Bluefish Caves are some of the earliest known sites of human habitation in Canada.
