We haven't studied that specifically, but from having worked in a number of communities over the years, I feel there are two aspects to that question. First, if they're removed from their homes and sent to a non-aboriginal family, we know that creates problems later on when they come to realize that they're aboriginal but they don't live in an aboriginal environment or follow their own traditions or culture.
A number of first nations and tribal organizations have taken responsibility for the child welfare system. They will remove the child from the home but will try as much as possible to keep the child in the community or in another community where there are relatives of the child. So you wouldn't see an Ojibway child being sent to a Blackfoot community. Rather, they would look for a place for that child where he or she would be safe and would be able to live the life of an Ojibway child.
