How is the University of Toronto compared to a top 50 US college in terms of reputation, undergrad teaching quality and quality of their admission pools? In addition, Do the colleges arts&sciences commuters enroll in have a huge impact on them or is it negligible? Does a UofT diploma show which college an arts&sciences student was in?
U of T is ranked 34 in the world by QS. If it were a US school, it would be ranked in the top 20.
A U of T diploma does not show which college the student was in. If you are a commuter, your college will be a place where you can eat on campus and a place where your registrar is. There are certain first year courses that are affiliated with one of the colleges and so students from that college has first dibs at registration time. Otherwise, it really won’t have much effect.
