How economically stable is the country? As an international student, would I be able to afford living there on my own?

Canada is quite stable, economically, but the cost of living is high, even outside the major cities. Much of Canada is rural, and most of the population lives within a close drive of the United States border. Living in Canada can be expensive, but you may be able to make it work, depending on where and what you study, what sort of part-time work you can do while at school, and so on.
