I’ve been making an effort to visit Canada and Europe more instead of domestic US tourism. I used to go to Florida multiple times a year. Not anymore and you know, Canada is such a great place, am there right now on vacation.
So I live in Florida. People leave Canada this time a year because of the weather. If anything, go further south to Central America. Costa Rica and Panama are safe countries.
They leave it because they have probabled lived in a winter climate their entire lives and want a change / have gotten older and it's harder on their bodies.
If you've never experienced a real winter or done neat things like winter sports then visiting Canada in the winter is a great travel experience.
