I am not French but I heard good things from some colleagues from Quebec (exactly like you, surprisingly) that speak French to native French colleagues as soon as they get a chance to, because they like to do so and don't feel mocked at all.

Of course they are aware of the accents, but you can still have fun and talk to each other. Then, of course, if the French mock them behind their back when they are alone, I will probably never know.
