If I go to Canada can I retire there and draw SS from the US? Also can I go to Canada buy a cabin or house with a plot of land and not work? Unless I just needed some walking around money?
It's easier for Canada to enforce these sort of requirements as they have about 12% of the population of the US. Americans are not moving to Canada in mass numbers like Mexico.
Edit: Okay, so non-citizens cannot buy residential property in census metropolitan areas or census agglomerations. A lot of rural areas are unaffected by the ban, including major tourist areas - Whistler, Banff, and Jasper.
