I applied to UBC, York, Carleton, and U of T's MA Political Science programs. Honestly, i don't think my applications are competitive at all, and upon a reflection on the application cycle submitted most of them in a haze of last-minute panic, under-researching my programs, and not contacting any of the professors beforehand in order to discuss placement. At the same time, as this is my first cycle, I'm prepared for the rejections and will take this in stride.
Agree on York - I'm really interested in the interdisciplinary approach as well as how diverse their faculty's interests are. I've heard U of T however doesn't provide any funding towards its MA students, unlike some of the other programs.
