"While emotionally I agree I can't see how in a democratic Capitalist Country we could do it. How many Canadians own homes in the U.S?"

This is a red herring. It has nothing at all to do with "democracy". And if the US doesn't want to protect ownership of US soil that that is their decision and has nothing - nothing - to do with what we do.But if the US wanted to copy us that would be just fine by me.
