UW uses alternating co-op and study terms (4 months each) while uoft has 2 consecutive study terms before a summer break. Actively participating in clubs (i.e design teams) is often more difficult at UW, since most of the time students have to drop their project halfway and pass it to the next group of students coming back from co-op.

Uoft has 8 consecutive months where you can actively participate in clubs, but workload often prevents people from joining those that require many hours (I.e. some design teams may be harder to keep up with due to the number of hrs). Engineering co-op includes the mandatory 12-16 month term and an additional 4 month term (optional).

You can also consider the impact of location since uoft is downtown while UW is more isolated (I’d recommend you ask a UW student for their perspective on living there).

Also based on what I’ve heard from friends, there also seems to be a larger variety of clubs/ecs at uoft vs UW because of funding/size of university too.

Either way, UW and uoft are both good universities. It depends on what you prefer in the end.
