I thought of Cornell when I read this; "I’d be interested in a urban/suburban non-denominational school with a more liberal atmosphere, amazing libraries, and preferably good choral groups (optional)! You appear academically capable & they will push you both academically and socially. Send me a PM if you want more info on Cornell, my D was a 2015 grad.
McGill is roughly the same cost for an out-of-province Canadian as what an in-state US public would be. Maybe $27,500 CAD which buys about $21,000 USD these days. Berkeley would cost the OP about $75,000 CAD per year. Full pay at an Ivy would be over $80,000 CAD. (Maybe the OP’s parents have a USD account.)
So @fogcity makes a good point about value. Which US schools are worth that kind of money to a Canadian with a 2360 SAT? Perhaps the ultra-elites, but if she’s going to end up working in Canada, wouldn’t a Cdn undergrad degree plus US grad degree accomplish the same thing for far less money? So OP, if you really want the US college undergrad experience, and you won’t receive much need-based aid, maybe look at full-ride merit awards at schools like Duke and Emory, if eligible, to get your costs as low as possible.
Thanks for the input, @Dunboyne 
That’s pretty much the reason I’m focussing on applying to really elite colleges over mere matches. I figure I might as well school in the states if I have the opportunity to study somewhere amazing, but I’d much rather go to UBC than UCLA for the cost and similar prestige (at least to me).
Eventually, I do wanna work in the US, though. Not entirely sure how much an American degree vs. a Canadian degree would impact that, if anybody would care to enlighten me.
A degree from a top Canadian university would be fully recognized by US employers. McGill, UToronto and UBC have large international enrolments including many Americans, especially McGill. You would need to seek internships and hustle for connections and opportunities just like at US schools. Your political EC’s in Canada would impress US employers, especially if you continued them at university.
BTW, my son is an American alum of McGill and he has had a great career since graduating.
U of Richmond has a PPEL (“L” is for Law) major. While technically within the city limits, it is not downtown and has a traditional, contained campus. Don’t know about the choral groups. This school would not be a reach but does attract a number of very high stats students (due in part to some high value merit awards). Richmond is approx. 2+ hours from Washington DC.
Someone else mentioned WashU. It has a popular poli sci major. it is liberal and nondenominational with about 12 or so libraries. It’s right on the border between being urban and suburban, and it has about 14 a capella groups (in addition to choir). WashU does have pretty selective merit-based scholarships, but at least they do offer those.
What about Georgetown?
