Thank you for your answers!
To Alexandra: firstly, in my question I meant going to live constantly, not only to learn French; and about quebecois accent - I really love it, but I'm still a beginner in French and I can't hear a lot of differences between quebecois accent and natural French.
To Polina: that's interesting, why do think so? As for me, of course I'd like to live in Europe, but...I'm Russian, I have another cultural and mental planks, so I think Canada is better for its multiculturalness)
