Ive been to ontario with my jeep from quebec, doorless havent had any problems with local law enforcement around the Ottawa area.
In quebec by law you need two rear view facing mirrors, so that can be a driver side mirror, plus your interior mirror.
To play it safe, get yourself a set of bicycle mirrors, the kind with the clamp for a handle bar, remove the clamp and just insert the threaded part into your doors hinge with a nut
