No BillMFI, not everywhere, but still in some places, although it's been reducing over time. We have Public Land Use Zones (PLUZ), and find in some of the very small towns a community park area or similar pull ins. Most large areas there is black top allowed at walmart, casinos, large gravelled areas in places. BC has various spots off logging roads and the like. There's a lot of back country camping but hard to access with a rig.
Generally we've always found somewhere on our travels across Canada east and west, with an exception of city ordinances. We don't have the amount of BLM, NFS, Trust Lands, LTVAs etc set aside you folks seem to enjoy on the west coast :(
