Ah yes, the ever-meritful anecdotal evidence. I will stand by and wait to see if you manage to bring forth any actual evidence that indicates Canadians want to revoke public healthcare in significant numbers.
Here's a question for you, and please take it seriously: if the number of Canadian voters who want an American-style healthcare system isnt an extreme minority, why is it that not a single member of parliament in the entire House of Commons (analogous to congressmember) has ever mentioned a willingness to revoke a single-payer healthcare system? Why hasnt any party, whether left-wing or right-wing, made promises to citizens that they will attempt to remove single-payer healthcare?
The conservative party of Canada has some policies that are arguably even more conservative than the states-- however, they 100% step away from health care.
Here is why: Tommy Douglas, the politician who spearheaded the fight for single-payer healthcare in Canada is routinely voted as the greatest Canadian of all time, across all population strata. A movement to revoke public healthcare is tantamount to political death. It would be like an American politician stating that they refuse to consider Israel's sovereignty-- actually, maybe even worse.
So while you have managed to have named three Canadians who (allegedly) prefer American healthcare, thankfully there isnt a single Canadian politician in the House who is even professing a desire to change the system to multi-payer.
