from my experience, Quebec is a good place for kids but not for parents ( except those who can speak very good french). yes,most chinese kids are perfect trilingle(englis/french/chinese) and for sure they will have many good oppurtunities in the future.
however,life for the parents are very tough no matter what degree & position you hold in China. languge is a big problem. frankly speaking, montreal is not a good place to improve english because too many non-english speaking people.you might think montreal must be a good place to learn french. true, but you forget how old you are now.except those who have great language talent, most chinese immigrant s here only know very basic french even they study very hard in COFI for ten months!
why? languges are for kids but not for aldults.
