sorry didn’t mean to put mcgill here as its 2 year!

Not to be an ass but if you can't handle undergrad, how do you think you'll do in a professional masters program?  Arch undergrad school is a 40hr/week commitment on a slow week... Grad programs are no different so the work load will be several magnitudes higher than what you've experienced in an urban design undergrad setting.  If you did poorly in social studies, you'll hate arch school.

Scratch McGill off the list because their cut off will be too high given it's one of the 2 top schools in the country.  Carleton is a smaller school so it's unlikely that you will get consideration given their smaller cohort sizes. UBC, on the other hand, is far larger than the others on your list so maybe you can slide in but it's unlikely given the high-competition level.

I know nothing of calgary, which means few of their students make it out of that city/province (I'm in Ontario and Quebec).

I never recommend UofT because it's a mediocre program but it may be worth it for you given they have a more reasonable bar for entry.

Some will say the folio is king and will be the main reason for yay or nay but you still need to make their minimum grad cut off.  I doubt anyone is looking at applicants below 3.0.

If your GPA is low and have no way to boost it then maybe consider gaining some real life experiences that could add to your resume.  I went to UBC and a number of the applicants had very little in the way of an undergraduate education but had worked as a contractor / carpenter and made it into the school... turned out to be a couple of the better students over my time there.

I went to Dal which has BEDS followed by a shortened M.Arch. UBC does something similar I believe. In my class there were a few people with even lower GPAs who had interesting portfolios. There were also people who did a non-degree year at an art school to boost GPA and build their portfolio prior to applying. At the time I think they looked at your 2 last years when calculating GPA.
