Definately ! In Montréal it's now almost half-half compared to Québec city where it's French everywhere. You will have no problem at all !
They're friendly too, just not as much as in Québec city
But, really, if you two go in Montréal, just drive 2 and a half hours more to spend at least 2 days here. It would be a pleasure to give you some spots to not miss. People are even nicer than in Montréal and the city is more beautiful and clean (sorry people from there !! lol) . I could give guys some hotel links to not go for the most expansive ones like the Château Frontenac, even if it's really nice And in Québec city, we're used to tourist and English is not a problem at all either. We're very welcoming !
