I'm likely going to be attending RFUMS and I'm very excited about it. I completely agree with your pros. However, I don't necessarily know if the interprofessionalism is that being of a deal and I've heard a lot of M1s have really liked the systems based curriculum. The EMT class was pretty unpopular I heard, but it sounds like they're taking a lot of feedback from the students and it should be a lot better this year. The big things for you sounds like it'll be comfort, weather, and match list. I don't know much about UofA, but Rosalind's match list always seems really strong, so if you're set on a speciality, I feel like you have a good chance from RFU.
Edit: I know interprofessionalism is a big deal throughout the campus, I just meant I don't think it'll negatively impact the medical eduction you receive there
