Healthcare needed in weeks is only years away.
Nothing new. 20 years ago, when I was living/working in SE Michigan (auto industry) there were clinics in the Detroit area that specifically catered to Canadians. CAT scans and even plain old X-rays especially, but also dentistry. Cash and carry.
OTOH in the ‘80s a motorcycle racing colleague dropped his Norton at Mosport, smashed his pelvis up badly. Was a month in hospital before he could be moved home to the States; he was never charged a dime.
