Choosing colleges

So most of my college apps fell through for one reason or another. I got rejected from Cornell, JHU (blessing in disguise?) and Northwestern, and waitlisted from Tufts. I'm also fully expecting a rej from UChic. Meh.
The only schools I got into worth looking at are McGill and Boston College. For the life of me, though, I can't seem to make up my mind. I mean, I think it goes something like this:
McGill
+One of the best schools in Canada
-...it's in Canada (My parents know a family friend from McGill; only got into med school on the 2nd year that he tried even though he had a decent GPA. I don't know any Canadians, but they do seem like they might be kinda weird.)
+drinking age is 18 (I think that must have at least some advantages)
+Montreal just seems like a kickass town from what I've seen of it
-It's just not a "normal" school, if you know what I mean. That goes back to the whole Canda thing.
+/-It's huge, dunno if that's a good or bad thing.
BC
+Generally seems good. Not special, but at least people know what it is.
+Seems as though the people there are fine, although my sister said that they're a bit on the preppy side
-It's in Boston. Maybe it's because I live near there or because I've seen all the wrong places, but it seems like one of the most boring cities on Earth. I'm not 21 either, so that'll probably take away some of the fun of being in a city in the first place.
I'll be doing premed most likely, by the way.
Any thoughts?
