NATS and Eurocontrol are you're two best bets. Just search for the websites. With them you just need to speak English, there is no other language requirement. If you are in Canada now then you may have cost implications getting across for the 3 + interview and aptitude selection process for each.
France is pretty protectionist about it, so I haven't heard of any foreigners getting in.
Apply and see what happens, but Nav Canada seem like a good option too.
Good luck with whatever you choose.
