I grew up in Vancouver, and have lived here all my life. I now live in Delta, which is a city, but I consider the outskirts cities to be more like suburbs of Vancouver. I don't know Boston, so I can't compare the two cities. Also, being old and married, I can't really comment on the night-life.
I think that the greater Vancouver area is a great place to live. However, in my opinion, the transit sucks, and the rush hour is about 4 hours long. I think it's probably a fairly expensive place to live, and property prices are through the roof. Unless you are a professional, with some hefty cash up front, you can't afford to buy a house in Vancouver itself. I'd guess you're looking at around $400K Can. to get started with a 33 ft. wide lot in Vancouver. And that would be a dump. Vancouver condo, maybe $200K and up? You can start here...........
and zero in on Vancouver or it's 'suburbs' to get accurate housing info.
What sort of work do you do?
Most people complain about the rain here the most. Recent summers have been dry and hot, and winter it doesn't usually go much below freezing. We don't get much snow, and no one can drive in the snow worth shit around here.
If you ski, however.......... the ski hills are awesome. Check out Whistler/Blackcomb for info.
Hope that helps. Ask more specific questions if you want.
