I see you're accepted to U Windsor, so just to let you know: TD's probably your best option if you go there, since the bank is about five minutes down the street from campus, and the student account I had from them had no fees/minimum balance. Other banks are accessible, but mostly downtown or by the grocery plaza (25 - 40 minute walk). Other notes I'd make is that if you go there, you should be able to find a place around the university to rent fairly cheap/fast, and the cost of living is not very high. Job market is awful if you're expecting to work outside of school, though. Just factors I'd want to know about, I think!
TakeruK covered a lot, but feel free to message me if you settle on U Windsor. I went there for undergrad and my MA.
Ontario itself is pretty big. Perspective: both one of my school friends from Windsor and I come from northern Ontario. We live more than 15 hours apart by car. But to be honest, it depends on the kind of person you are, re: where you might like visiting. If you dig nature/camping, cities, major tourist attractions, certain sports/activities -- it definitely factors in. If I were to go anywhere within a day of Windsor, I'd head to Toronto, Ottawa, or Montreal, as I love urban exploring and they all have a lot to offer in different ways.
