The situation is slightly different. It isn't done formally. We represent the members of the academic staff of Quebec's anglophone universities. It is difficult to be a unilingual anglophone in that province. Even if it were a formal requirement, someone who couldn't get along in French would have trouble, whether it be at Concordia, McGill or Bishop's.
There are also bilingual universities in Ontario, such as the University of Ottawa and Laurentian University.
