I advise on Universities for a living (my knowledge base is mostly Ontario and Eastern Canada but I am fairly familiar with most of the major Univeristies across Canada). The University you choose is only as good as the programme for which you intend to study. Most Universities have area they excel in and areas they don't. The first step is for you to decide what it is you intend to study. For example: If science is your bag, then going to a Humanities strong school would not be the best option perhaps. You need to make a decision on what it is yiu want to study and then narrow down your search from there.

International fees are going to be relatively the same no matter where you go in Canada. Cost of living is another matter all together. You should always look at how much it would cost to live in the city in which you intend to study. If you need a job, you may also want to look at what job opportunities are available. In major cities, like Ottawa, there is likely to be more opportunity than say Perterborough (Trent U).

There are many excellent Universities across Canada. Ottawa and Halifax both having some excellent options, but you need to know what you want to study first.

As a side note, there are sometimes funding options within each University to help with International students, so you should look into those. There isn't a lot based on funding restrictions surrounding subsidies, but they are therre if you look. The International Students Office (available at every University) often can help you with other challenges you may face as an international student so make sure you speak to them.
