Generally if you are short-listed in a school, there is a faculty member who is interested in working with you. At that point your chances are much higher to receive an admission, and as other posters have said, I don't think there are many cases in clinical where people receive an offer without first having an interview (online/phone/in-person). Also you say UBC is your dream school which is awesome, but also try to consider the faculty members & research area you want to work in.
Grad students & profs alike will tell you like you need to focus on the professor almost more so than the school (obviously do your homework - research if it is accredited, good licensing rates, funding opportunities, livable city, etc.) and I would urge you to do the same! This would also take a lot of pressure of yourself for trying to get into a specific school when a POI might not even be accepting students that year.
