Metis
The Metis are a group of aboriginal people in Canada who trace their descendants back to the First Nations and European settlers. In the early part of European expansion into Canada the Metis were a tribe of aboriginal people that lived in the North Western part of Canada. The Metis people today are an interesting group because most of them are not direct result of intermarriage between European and First Nations people. The Metis primarily live in the Western Part of Canada and today there are about 500,000 people considered part of the Metis community. They represent about a third of the aboriginal people in Canada today. However, because of assimilation of Metis into European Canadian populations, many people can trace their ancestry back to some aboriginal past. Much of this interaction occurred in the mid 20th century with the fur trade as many European Canadians interacted with Metis tribes. Because of this, today it is hard to define someone who has a clear legal or moral ability to call themselves Metis because of the extensive assimilation into the Euro-Canadian culture. Unfortunately, "a universal consequence of the meetings of people is the rise of a mixed population whose social status is ambiguous..." This is partially true for the Metis today because there it is hard for the Canadian government to discern what people are Metis. When Berger refers to the Metis in this report he is most likely talking about a tribe of aboriginal people who identify themselves as Metis.
