It's gonna be interesting for me. I'm about to move to Montreal (flight is in 2 days). I want to learn French very well to idle-mine immigration points. I'm gonna make mistakes. That's just how it is. The surest path to success is failure.
Just stick to your guns of speaking in French and let people know you want to practice, and you'll do great!
And congratulations on the move! It's a wonderful city. So wonderful that I'm moving back there in a month after being in the Toronto region for almost 10 years.
