I don't know. There was no such case on our commission. I don't believe there was any. There has previously been one incident. That was in another province; it wasn't in Quebec, but I forget exactly where it was.
During the last commission in New Brunswick, when they took the courses, I know that they talked about establishing a specific riding to represent the aboriginal community. However, people asked what could be done to enable aboriginal people to be part of a single riding. An appeal was even instituted in court, and an amendment was subsequently made.
In short, that is the only occasion that I know of where there was any particular discussion.
