I think it’s very wrong to jump to the conclusion that DR shortages in Canada would translate to Dr shortages of US were to go universal with their healthcare.
Look at a map. Canada is a huge country, and while populated somewhat evenly along our southern border, much more sparsely so to the northern reaches. Still our system strives to deliver equal access for all, no matter how far flung.
That alone presents challenges that the US simply would not face, on the same scale.
There are times when our system flies people, from distant locations, into places like Edmonton for treatment. Because it’s much more economical that trying to set up another cancer treatment centre in a place you’ll struggle to find Drs willing to live.
There are also times when it’s more economical to send a temporary overflow, of some service, across the border, than to buy more MRI machines etc.
All to say, some of what you hear opponents spouting, about people having to go to the US, or lack of Drs, or wait times, isn’t always as it seems.
It’s helpful to remember, those that are hugely profiting from healthcare in the US, are always drooling to find a way into the Canadian system. To get a foot in the door. Our system is always under this pressure. Those who would profit have deep pockets and contribute to political campaigns here as in the US.
Still, thus far Canadians have been loudly standing firm on such changes. They’d rather have the challenges I’ve mentioned, and a not perfect system, than ever see rich get access while the poor are treated as lesser.
Just my opinion, of course!
