Guelph is very much the same. We start after labour day, and then start the second week in January (except for the Vet college which starts Jan 2nd...my roomie is a vet student) and we get out the middle of April (about the 17th or so...not sure). At Guelp the Vet students start earlier and get out later, but they have so much more to learn
I'm also from the province of Ontario.
