With the exception of private schools.... In other provinces, francophones are entitled to their own school system, but our opinion is that the English situation in Quebec is unique in Canada, because francophones outside the province who have separate schools often live in an overwhelmingly anglophone environment. That helps them to learn English.
I grew up in Montreal, and I don't speak enough French to get a lot of jobs in Quebec. Most of the people I grew up with have left the province because they were somewhat bilingual but not competitively bilingual to be able to work in Montreal.
So this is a unique situation where even though we're a minority language in Quebec, there's often not enough French in our daily lives to make us competitively bilingual.
So yes, francophones can have separate schools. We're not advocating integrated schools for francophones outside Quebec, because their reality is very different from ours. Ours is a unique situation, specific to Quebec.
That's why we're the only official language group advocating some kind of integration of anglophone students with francophone students.
