your own mind. It also depends on what kind of person you are (I mean your characteristic). You can find a lot of new and old immigrants' experience in Canada, and you may also find that different people have different opinions. Since you are the only person who knows yourself well, you are the only one who can make the decision. Nobody knows what will happen to you 10 years later. Still the answer is unknown, but you should follow your willings and do not feel regret of your choice.
