That's some blatant misinformation. In Canada you don't wait for treatment. If you need treatment, you will be treated. Stop spreading some garbage myth.
I don't know where you live in Canada, but that's not entirely true. There are long waits for some procedures (far longer than medically indicated) and a significant number of people cannot access primary care because of the shortage of GPs (especially in rural areas). I would still, 100%, rather live in Canada than the US but your comment (intentionally or not) completely glosses over the waiting lists for some medical specialties.
People in the US see short lines and think "wow I can use our system whenever I want" instead of "wow our system is so expensive that it's usage is much lower than capacity".
Yeah, is clear him and thousands of others like him around the internet have a very clear agenda posting about how they believe the US health care system is great, that going bankrupt for healthcare services (or dying because they couldn't afford meds[0]) is just an acceptable and normal part of American society.
