I would add that the Métis are under-enumerated. There's nothing from StatsCan that would accurately reflect the number of Métis people anywhere in Canada, including urban centres. Métis people have never found an advantage to identify who they are, so when there's a census, they don't necessarily say who they are.
This started back with our veterans when they enlisted and were asked their ethnicity. When they said “Métis”, they were told there's no such thing. They looked at their surnames, and then depending on what it sounded like, they said they were a Scottish Canadian or a French Canadian. They just gave up.
It could also be viewed as a way to enable discrimination, so Métis people don't necessarily self-identify.
