That's his shameful legacy. It should not matter if they speak English or French (or Chinese, or Spanish, etc.), that should never be a job issue.
Canada basically has one official language: French. It is despite the fact that less than 20% of the population speaks French (and outside Quebec, more speak Chinese than French!)
I think I disagree. I've lived in 5 provinces and only in Quebec was it "necessary" to be able to speak French. In the rest of the country it simply wasn't an issue. Even in Quebec one can get by with English.
