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.
