I'm currently at OISE for MT and I wanted to share some of the things that have been going on this year to help with your decision making:
OISE's program is more expensive at $12,500/year. Classes have more hours than a typical B.Ed. course, thereby necessitating a summer term. However, you earn the same number of credits of a B.Ed.; because of this, QECO (The Qualifications Evaluation Council of Ontario) has classified it the same as a B.Ed in January 2018. You cannot use this "Master's" toward principal qualifications. You also come out at the same pay scale as you would with a B.Ed (A3). OISE has been, for the last few years, vaguely putting out the idea that you come out at a higher pay scale (A3+ or A4) and have a Master's degree and teacher certification. It's become clear that this is not the case. The entire student body is seething with outrage. Many students have dropped the program. I've heard from one friend who left that she spoke to another Canadian university and that they don't consider this program to be a Master's at all.
As for the program itself: The research component of this program is laughable. In fact, nearly all of the courses are filled with fluff. Every class is three hours, and for most of these classes, half of it is spent "reflecting." There is no rigour in this program, no organization, no accountability. I cannot believe the gargantuan gap in quality between undergrad at U of T and this mess.
Ask yourself this: Is it worth spending 50% more for a glorified B.Ed. that is a Master's in name only, that is 25% longer, for no added benefit?
