Read that BBC article, it said Canada has better treatment for cystic fibrosis than the US does and wider spread in terms of access to those treatments.
The US has the best care for the wealthy, but if a 30 something working poor guy in Canada and the US were hit by a truck, who would access care that wouldn't give them a huge bill that could bankrupt him?
Also, how do you know most of the medical bankruptcies are related to injuries that prevent work rather than the bills incurred by the treatment itself? Also are you sure you know a lot about the Canadian system, there are a lot of US myths about it:
For decades, the health insurance industry has been scaring Americans about Canada's health care system. We hear from a whistleblower about his role in the disinformation campaign.

Medical bills can cause bankruptcies. Medical costs impact both household finances and the economy as a whole.
