Just south of us are 26million uninsured people who desperately need healthcare and 100million in medical debt. We can't afford to support them, nor do i really want to more directly support america. So how do we, from a legal point of view, differentiate between the small sustainable group of people above vs the potential huge group of people, niether would have paperwork, both need help.

This isn't just concern trolling, if you have a genuine answer to that question I'm all ears, but I have 0 doubt in my mind that if there's a backdoor way for Americans to get canadian healthcare they will take that option en mass.

I think the best way to solve the program of the undocumented workers above is to make the path to legal immigration easier to transfer into and to grant medical coverage earlier in the immigration process.
