content: I'm not a Quebecois but I am Canadian, so I think I can. The English customers are asking where the cheese comes from. They assume it comes from Quebec because it is really good and the French are known for good cheese. The waiter tells them, in a strong accent, that it was shipped from Toronto (an English city in Ontario), but the customers think it must be some region in the big French city. They don't hear 'Toronto' they hear what they think is a French name, because of the accent. Or they just don't know what Toronto is. Like anything, it is not funny when explained. And I may be wrong. Jokes have flown over my head before. People in Quebec city, and Montreal deal with a lot of tourists, from all over. And the tourists often have a lot of strange expectations, and assumptions, about the French Canadian citys and culture. So this probably would be very funny for the locals.
