You will have your own preferences as to where you want to travel of course, but for ourselves, just visiting the Montreal area for a few days in 2009, after a winter in Mexico, and going back to B.C. the first of April with no inkling to visit Toronto, and seeing no other RVs on the road, we headed towards Ottawa, by-passed it (leaving it for a later visit) and traveled Hwy 17. It's a long way across Ontario but this shortens it a little. Stuck in Thunder Bay by a 40 cm snowfall, delayed us a couple of days. May will be better! Living on the south coast of B.C. we never realised just how long winters can last, especially in Quebec.
