You used a very important word: “Montreal”. Actually, I'm talking about Quebec, all of Quebec, all regions, including major centres. It is clear in the regions that the use of English before the courts is in significant decline, as is the bilingualism of judges, clerks, administrative judges, authorities, officials and the court administrative staff. In my experience, even in Montreal, in the Montreal administrative tribunals, it is a matter of courtesy.
