Yes, it's far easier in certain states in the US, as I said. Cheaper to purchase, too.
When you leave Canada with your car, no one will stop you. No one will ask you whether you're coming back. When your insurance runs out, no one will chase after you and shake the money out of your wallet. Really. That's a good thing, since your Canadian insurance is no good anyplace in the world but the US and Canada. Note that the OP is not talking about driving across to the States and then staying permanently. He's going to carry on to the far-flung corners of the world. Think they'll care in Africa or Cambodia whether he exported properly upon leaving Canada?
There is the minor problem of your registration being cancelled when your insurance lapses--at least in B.C. Again, best to purchase and register a car in one of the US states which allows this.
I wild-camp all over the place in Alberta, BC, and the Yukon. No one cares. It's been decades (literally) since anyone's bothered me. I'm not sure why your experience is so much worse than mine. Of course, I'm not obnoxious about it--but I used to do this right out in the open in farmer's fields, construction sites, abandoned buildings. Even back then, no one gave me a serious hard time although every so often the police would come around to smell my breath and check to see I wasn't wanted.
best,
Mark
