Probably about $1 million. Canada is easily one of the best countries in the world, but I wouldn't mind moving to San Francisco if I had enough money for a nice place and I wouldn't really have to worry about getting a real job for a while.
It would definitely suck to never be able to come back since I love this place, but starting a new life sounds exciting enough that I'd probably take the money and then just regret it later.
