I'd like to offer a different perspective on why you should go to Queen's, in addition to everything stated above.
I have found that lawyers coming from Ontario schools have a surprisingly easier time finding jobs in Western Canada (sometimes, even easier than some graduates of Western Canadian schools). This appears to mirror a general trend in Canada where it's easier to move East to West, and much harder to move West to East. In my cohort, a handful of students secured jobs at big firms in Western provinces without having necessarily the most competitive grades. I do note, however, that many of these people were originally from out West (i.e., they were able to establish a connection). Even so, I also notice many Western firms respect Bay Street experience - that is, if you want to move out there one day in the future after working for some years here.
Just a thought. Also, I'd like to qualify the above observation by noting these are just some observations I've noted over the years, and it may not hold necessarily true in all cases.
There is literally no point* in living in Vancouver unless you're going to stick around for the summers, so I would take that into consideration.
* - I guess you could get up to the city mountains a couple times as a law student with the odd trip to a bigger hill. In that case, there may be one point.
