I've accepted an offer at Ryerson (Literatures of Modernity) and it looks like a great program!
I have a friend who started there this past fall and is really enjoying it. I haven't heard much in favour of UofT's program (too big, no funding, detached, etc.) and I haven't heard much at all about York. But it depends what you're looking for. Ryerson seems to be more of a creative MA in terms of being able to do almost anything with your major research project (sort of an open-to-interpretation thesis) or a practicum, and the course listings emphasis more contemporary works over the canon-based education you might find elsewhere. Creative suits me best, so it's likely that my take on the other schools is on account of having friends with similar interests.
Since all the schools are in the same city, are you able to go visit for a weekend and meet with the graduate program directors to get a better sense of the programs?
