Allstays has pretty decent coverage of Canada. They have a free online map or paid Apple app or also a pro subscription. I reviewed it recently https://www.loveyourrv.com/allstays-pro-for-rv-trip-planning/

Another one that is good for finding public camping sites is called Ultimate Campgrounds - http://www.ultimatecampgrounds.com/index.php/products/full-map

For free or cheap camping try https://freecampsites.net/

Another is www.campendium.com . Some use iOverlander.

A friend, Ron Haidenger, who is also an Admin on RV Canadians FB, is in the process of building a free resource that will be better than those currently available, that will be strictly Canadian but with the addition of Alaska. It’s a complicated process, but he’s getting there. It will be called Road Trip’n Canada

Thanks. I have those, just wasnt’t sure which ones had the best coverage for Canada.
