As for the province of Ontario, take the TransCanada Highway. The route around Lake Superior and Georgian Bay is very scenic. There are 2 spectacular Provincial Parks worth stopping that are on Lake Superior: Sleeping Giant Provincial Park and Lake Superior Provincial Park. After that I would head East to Algonquin Provincial Park (there are so many bears, wolves and moose you are almost guaranteed a sighting)and then continue East to the Ottawa River and follow it down thru Ottawa and on to Montreal. If you are into museums you can stop in Ottawa. The museums are a little like the Smithsonian but not quite as big.
