This is happening throughout the autocratic world, as authoritarian leaders crack down on institutions of higher learning. This has already happened in Russia and Hungary. The populations of both countries are declining, as they refuse continue to brutally punish dissent or even criticism.
The ones who are leaving, are the best and the brightest because they have the most options available to them. The ones who are left behind, are the oldest, the least educated, and the least able to thrive elsewhere. The population of both Russia and Hungary is aging, and less productive that in the past. Putin's war with the Ukraine has accelerated the process of military age, well educated men, fleeing military service. Like the Viet Nam draft dodgers who came to Canada and never left.
Now Canada is seeing an influx of physicians from the USA, who are fed up with being targeted by rabid anti-abortionists, and unable to properly care for patients in distress because of a patchwork of differing laws and prohibitions across every state. They tired of seeing patients suffer because of laws which ignore women's reproductive biology in an all out effort to force women to have more babies.
The best and the brightest will be scooped up faster than we can say "Here's your "Landed Immigrant Status Card", your Social Insurance Number, and your OHIP (Medical benefits) Card. Let us introduce you to head of [your professional association], who will see to it that your credentials and licenses are issued promptly. Here's a list of resettlement resources and programs. Welcome to Canada".
After years of watching the doctors and nurses Canadian taxpayers paid to educate and train, being scooped up by American hospitals and clinics, while we continue to suffer under a severe shortage of PCP's, all I can say is "Welcome to Canada".
