I have a summer toy.
In the winter, I drop the collision and the liability and keep the comp in case it gets stolen. (Drop the insurance around November, put it on end of May. So it's insured June, July, August, September, October.)
I maintain insurance on my day to day driver all year long.
No problems. I pay by the month in order to keep it simple and allow me to do stuff like that easily.
I live in Toronto and my broker is TD Meloche Monnex. The plates are on the car and it sits in my garage. I don't take it out (don't want to in the snow anyway.)
So no, there shouldn't be any problem.
