That's a good question. The answer is easy. First of all, I'll throw the question back at you by asking you how you answer Statistics Canada when you check the little box marked “first official language spoken”. But the real answer is that we rely on the community to define its members. Some communities in Saskatchewan—that some of your colleagues know well—increasingly tend to include in their definition people for whom French is not their mother tongue or even their first official language spoken, but who are francophiles. They are making major efforts to include in their cultural, youth and other events young people and citizens who are learning French, in order to reach out them.
