I'm born in Brazil and lived in both Toronto and SF. Honestly, the weather in Toronto is really not that bad. My wife calls it "having proper seasons". SF weather is somewhat cool all year round and you always need a sweater at dusk/dawn, whereas Toronto summer is actually hot. Also, going to the beach in Toronto is surprisingly nice - lake water is always calm (great for kids), no freezing wind and no fog. If the problem is only winter, Vancouver's winter can hardly be called extreme, since it rarely dips below freezing point in the city. The elephant in the room when it comes to salaries in the US-vs-Canada discussion that young people seem to not realize is that, in Canada, it's fairly trivial for a spouse to get a work visa and get a decent income even outside of the tech sector, whereas you're more or less forced to be a stay-at-home-mom family if you're planning to build a life in the US.
