I have friends and family who said they would move to Canada if Trump was elected. Haven't heard any more from them on the subject lately.
Another thing to consider is how expensive it is to live in these countries. I know for example that Canada has heavy sales taxes on just about everything, which fund their "free" health care, among other things. Sure, these countries might be beautiful and their political system may align with your political beliefs, but they aren't utopias. You can go broke quickly living in these countries.
