Like everyone else says, depends what you want.

If you can afford it, Vancouver is amazing (though, I am a biased Vancouverite.) In a good season, there are local ski mountains about 30 or 40 minutes from downtown, Whistler is a couple hours away. There's awesome food all over the place, the underground scene is a blast and even some of the licensed etc venues can be pretty awesome. In the summer, everyone wants to be outside and if you're into sporty stuff, there's a boatload to do. The weather is generally pretty mild (though climate change is messing with that.)

The transit system can be amazing, depending on where you live. (In the suburbs, like most other cities, it's kind of trash.) But there are trains, rapid busses etc if you live near any hub. And of course, bike paths galore!
