Haha thanks for the intel and I will check my Quest daily like a mad man!
UWaterloo is indeed very research-oriented, so I'd say it is a bit tricky and personal for me to say anything. The co-op thing, however, is more in the undergraduate level I'm afraid...although the planning grad program requires a summer internship, it is probably not the same structure/scale as their famous co-op education. That said, if you prefer working and living in Ontario (like me), UWaterloo is an excellent starting point with lots of resources and recognition! Same goes to Queen's as you also pointed out. These two programs are both very well known in the planning profession in Ontario, some say even more than that in UofT.
I didn't apply to Manitoba simply and mainly because its deadline was one of the earliest and I missed it lol. I don't have much intel about its planning program either so I can't give any insight.
For me, personally, if I were genuinely very into something, I'll excel it very much easier 'cause I'll go above and beyond autonomously. And vice versa, regrettably. Of course not everyone is like me, though. Just my two cents.
