From my recollection, perfectly legal to own and possess in Canada. The Radiocommunications Act is pretty grey in regard to specific legalities. But like others have said, as long as you're not operating while driving and this constitutes distracted driving.
I know there are some people in emergency services who think scanners should be illegal to possess and operate, etc... but that is a whole
other topics for another day, so I digress.
Enjoy your trip and safe travels.
