Just to hop in on the housing discussion, a great website that I used to find my place was rentals.ca. Unlike kijiji etc. which can be kind of unreliable and prone to scams, this website lets you look at listings on their map view so you can immediately find ones that are a decent commute to campus (which is important). You can also set your price range and the number of bedrooms/bathrooms you're looking for. I wouldn't really recommend purchasing a place in Ottawa unless you think you're going to live there for a very substantial length of time, it's much cheaper to rent a place.
Hope this helps!
