Each year's freshman MT class generally holds in between 20 and 25. The acting classes tend to hold 30 to 35. I would assume that acceptance is offered to around twice the lowest number of class members, so about 40 MT acceptances and 60 acting acceptances, but these are really just estimates. As UArts has a waiting list, it could be a large exaggeration as well. Though I've been a student there, I've never asked about the acceptance process and am not sure it's incredibly clear-cut as to which waitlisted person would be the next in line for acceptance if two people had the same audition score.
We all know that Universities accept more students than they would want, just as airlines tend to "overbook." Statistics show that it tends to work out better for Universities than for airlines, though.
