Canadian banks are virtually useless to you. The best you'll get out of it is a Line of Credit, which doesn't help unless you have tons saved up -- under your visa, you're only allowed on-campus employment while at school, and it doesn't exactly pay well.
National student loans are very useful now that the Canadian dollar has strengthened so much. Unfortunately, they max out at 48K lifetime (I think) and 13-something K a year (I think, again, but I know it's not much more than this).
So, realistically, you're going to need private loans. Currently, unless you go to one of a very limited number of schools, your only viable option is the CanHelp student loans. They're not exactly ideal. The interest rates are fairly high, and they compound while they're in deferment, which is a f-ing pain in the ass, to say the least. That said, they were prompt, and much more reliable than my Canadian student loans were. Also, if your credit history is well-established and you have good to great credit, you may even be able to get one of these loans without a co-signer. My credit is very average at the best of times, and I had to get my parents to co-sign. I didn't like it, but it's reality for me. However, with scholarships and government student loans, it looks like I'll be able to keep my total private loans to about 60K, which isn't too disastrous.
gilles may have more to add, but this is the best advice I can give you right now. Feel free to ask more questions.
