I can agree with you about pulling out a dead moose from a dehavilland beaver as I have done this myself several times whilst flying floats in northern Canada.

As for hour building in Ontario there are a lot of options. Most school charge a relatively same rate for aircraft rentals. Near the Toronto area I would recommed Spectrum Airways out of Burlington. You don't have to pay a membership to rent airplanes contrary to other flight schools. They don't have many airplanes but the people are nice and it's not too busy at the uncontrolled airport. here is the link

Have a good time in Canada it's a great place but bring some warm clothes for the upcoming winter
