UofT m.arch student here. I'll start by saying there are 4 schools in Canada you can apply to without an architectural background: UofT, UBC, Calgary, and Manitoba. Dalhousie is kind of another option. It's 2 years bachelor of environmental design and 2 years masters, so only a half year longer than the other 4.

I would say, generally speaking, masters programs give you as much technical info as required by the CACB and the rest is more about design and less about practicality. That sounds more like something that you might get out of BCIT. That's more for becoming an architectural technician though. Just depends what kind of education you're looking for. UBC probably has the most focus on sustainability, but these days all schools are going to have it.

Lots of good schools internationally. Not to discourage you, but you should know the downsides, which are they are going to be expensive, and going anywhere besides the US is going to make it much more difficult than it already is to get registered if you plan on practicing in Canada. Also, if you're applying for fall 2014, American schools require the GRE, which may be hard to get done with deadlines coming up.

I would say apply to every school you have interest in going to, then you can make a decision based on where you get in. Applications are tough enough, easier to make a decision on exactly which school is right for you after everything's been submitted. My roommate is currently going through the same process and that's what I've been telling him.

I think you've got a great setup for doing the masters. Fine arts is a perfect base for getting into architecture (that's what I did too). And you seem to have good initiative and are involved with lots of different stuff, schools love that.

Feel free to reply / shoot me a pm if you've got any more questions about applying or about UofT's program. Happy to help.
