I'm curious about Canada. My plan is to make a lot of money in the states and retire early, then apply for Canadian citizenship and move to Canada to cover health expenses. Even if the citizenship process takes 2-4 years, would this be worth it?

Canada’s immigration process is based on a points system. If you are not working, don’t speak French or are over a certain age, then I wouldn’t rate your chances too highly. The reason is the “move to Canada to cover health expenses” part. If you have never paid into the system via taxes by working and living here, then why would we want you?

Immigration to Canada is notoriously difficult without family ties: https://www.canada.ca/en/immigration-refugees-citizenship/se...

The older you get and not working make it a lot harder, as many people have your plan.

So if you want to do that, come to Canada before you retire and having a job here will help you get in.

That won't be easy unless you marry a Canadian citizen. That's what my cousin did and now he's a citizen after all these years.

In Ontario, there is a provincial drug plan for 65+. I think Quebec has something similar. Ontario tried to extend it to all but the government change a few years back killed that.
