In BC in the 80s there was no requirement to learn French in school. A second language, minimum 1 yr I think in high school, but it didn’t have to be French.
Is French now mandatory? (I haven’t lived in Canada since 2000).
You could check the BC Curriculum website yourself, but it’s structured so poorly that it’s impossible to tell which subjects are required and which are elective. Core and immersion French are clearly on offer, but that’s about all I can tell you.
