To your point, I would say that most Franco-Manitobans and Franco-Ontarians are bilingual, but it doesn't mean that they don't live in French. What those communities are telling us is that they need more francophone immigrants and more support for integration services. They say that making services available in French is important to stop the decline of French.
You said francophone immigration doesn't stop the decline of French, but communities are telling us the opposite. Why do you have a different view?
