Hi I am Canadian in Ontario. PEI is small and closeknit-I imagine you would like the smaller community. Pretty too from all I hear.
University of Guelph is reknown for its vet program and vet learning hospital. I have had several friends graduate from the program in the last 10 years. Lovely smaller city too. Not so much traffic as larger cities and very green with parks. Lots of styles of accomodation. A walkable city. I went to this university for art. Lovely, manageable size campus. Beautiful old stone buildings.
Guelph is an hour away from the major TO airport(Pearson). The community is settled up against agriculture and small towns but close to TO with very straightforward highways.Excellent shopping, restaurants, public transit, and accessible.
They like to hear if you wish to be a large animal vet as we need more of them.
Have you contacted any of these universities to find out more?
Good luck!
