If your a Canadian citizen with %50+ native blood you can apply for a green card / citizenship at the border because of the jay treaty. That's a very small amount of people although. Canada is a lot more stringent about jay treaty rights in this case although than the US. It's actually harder!
I really doubt though all of these guy's details are correct, since it would mean all native born Canadians could just apply for US citizenship on the border, and I would think there would be some CBC article about it by now.
Also if you do stuff like 'put your house under a trust' or any other corporation, then you lose things like the 250k cap gains exemption on a house you directly own and live in when you sell it.
So definitely a YMMV. This feels like all of the 'you don't actually have to pay income tax' crap if you do this magical bureaucracy incantation you see on the internet.
