I worked at the fighter wing in Cold Lake. Now I'm at division headquarters, in Winnipeg. We oversee the wings.
I think bilingualism is present in both wings, but obviously, Cold Lake is more English-speaking and Bagotville is more French-speaking. I think the fact that francophones at the Cold Lake wing are immersed in English and, similarly, that anglophones at the Bagotville wing are immersed in French really helps the members of the air force build the skills to work in both languages. It's a bit like that now, but day-to-day activities are still conducted in English in the Royal Canadian Air Force.
