If you move out, the cost is around $7000 (including tuition) for two terms. This isn't including food, laundry, day-to-day living expenses, etc. UBC dorms for first-years are TINY. You can request to live in a single dorm, but if you sign up for a double room (which is cheaper), you don't get to pick your roomate unless you have a friend going and the two of you request to be roomates. Or if you already know a person and want to be that person's roommie and that person wants to be your roomie as well.

I don't live on campus yet, but I'm planning to move on campus when I do my post-graduate studies. Older students get to sign up for a townhouse :D.
