In 2018 I phoned the office Rep. Robert Pittenger (R-NC09). His aide told me that Canada's healthcare system was one of rationing and denying care. He said he knew, because growing up he had a friend from Canada who told him so, and that fact "impacted his entire life" on the issue of health care.
I asked him what his friends name was and where in Canada he lived. He told me he did not remember his name and didn't know where he lived.
It is very unlikely that you would remember something so important, that would then influence your entire adult political life, and not recall the important details.
So many who oppose the civilized nature and cost of Medicare For All, all have a friend from Canada. Just don't ask them too much about their phantom friend.
