*lowers voice* As others have pointed out, you cannot necessarily even emigrate to Canada, your neighbour, if you are disabled or have evidence of 'undue' healthcare spending, for example (real life example unfortunately) receiving treatment in the adult psychiatric care system... involuntarily. 🙃
There is an American exceptionalism embedded in the idea that y'all think you can just pick up and leave and go wherever you want. It's cute you think you'd be welcomed. Americans aren't exactly popular in the world.
I'm a Canadian ex pat who is disabled and hope to god the country doesn't decide to not let me come back. My spouse is very able bodied but American. Moving back will be ... complicated.
