The US would be switching to an entirely different system, but wouldn't be able to "refine" it? What a bunch of unprovable bullshit.

Not 10 minutes after they implement it, no. Canada has a mature system that's been worked on for decades. Are you suggesting the US would be automatically better just because it's the US? What are you, a MAGA?

Also, if you think the US doesn't already have waiting lists for specialists

I've been to a variety of specialists, it's never taken anywhere near a month. My understanding is that in Canada a month is the norm, sometimes longer.
