In fact, we need French-speaking immigrants throughout Canada. That's kind of the point I'm trying to make. If the number of francophones drops in Quebec, it's going to drop everywhere in Canada. There's already a lot of interprovincial migration, so there's no need to encourage that.
The Canada-Quebec agreement on immigration is an example of how the asymmetry of the language issue was recognized 50 years ago. In this agreement, as in previous ones, the federal government clearly recognized the need to protect French in Quebec. To this was added Bill C‑13, which specifies that Canada should not implement policies that run counter to the objective of protecting French in all provinces, including Quebec.
