You talked about law studies, for example. Someone can be a lawyer and only speak English, but a francophone lawyer who doesn't speak English won't go far.
I'm sponsoring a bill, and I'm going to speak briefly. I think that Supreme Court justices should be bilingual. If that were an obligation, don't you think that would encourage university law students to learn the second language? If one day they want to become judges in the Supreme Court, they'll have to know both languages.
