Why those 3 countries in particular? Wouldn’t this work anywhere (provided it’s not in a war zone or a volcano zone etc)?

Gotta pick the right environment+tree combination.

You could always settle in the Mojave, plant a grove of bristlecone pines instead.

I don't know if more boreal climates support longevity, I think it has to be some combination of temperate + dry + safe from natural disasters like wildfires and hurricanes

You are... unlikely to grow an olive tree successfully in Toronto.

Even for other kinds of long-lived trees, places without big ice storms, hurricanes, etc. that would prematurely end the tree are probably safer bets.

Wait a few decades and olive trees should grow fine in Toronto. Climate change ftw
