I am in the middle of completing a professional MSc with research as well, and had the same question. This is the response I got from the U of T admin when I asked a few months ago.
"Unless you have substantial research productivity (usually, a minimum of one first author publication), you would more likely be assessed as an undergraduate i.e. the competitive minimum is currently in the region of 3.8. Each graduate case is assessed based on the application materials submitted but the academic CV is really what determines eligibility for a graduate review"
Hope that helps!
