Canada

The funny thing about immigration is that it turns out I don't need to research every single 'might be good, might be bad' country out there. I only needed to find a single country that had lenient immigration laws and would be accepting of me. Australia was that country for me, though it has it's own issues as all countries do. Personally, I don't think I should need to have some degree in foreign politics to be able to decide which countries would/wouldn't be welcoming to me. If anything, if Canada has some massive propaganda problem where all searchable metrics (58% Trudeau disapproval ratings, 58% think too much immigration, 41% anxious immigrant rights get too much attention), then perhaps "too much propaganda" is yet another reason to avoid Canada.

I wasn't reading news articles so much as I as reading Reddit comments (back when I still used Reddit), which is certainly still not a completely comprehensive read of the whole Canadian population, but it's about as close as I can get without being in Canada myself. To be honest though, having most of the media controlled by right wing groups is another concern, though I do hope your elections go well

I think it's important to remember immigration isn't just some lever you can turn on and off: "oh we're having issues with quality of life so let's stop letting immigrants in," "oh but we want highly educated people like doctors so lets let them in." Prospective immigrants will remember at best the wishy-washy stance on whether or not immigrants should be let in, at worst the outright xenophobic sentiment they had heard. This especially goes for people in highly educated professions like doctors, who are desirable immigrants in any countries, and thus have options to pick and choose where they want to go.

I know when my parents (who are both doctors) started looking into investing a bit in other countries, Canada wasn't even considered, they went straight to investing in Europe. When I told them I was looking into foreign colleges, they suggested schools in New Zealand, in Germany, in Sweden.. they didn't once recommend Canada. Well, this is just anecdotal evidence, and I'm sure many many American doctors will flee to Canada. But I wouldn't assume just because doctors are leaving the US necessarily means they're going to Canada
