Waterloo in Ontario has the strongest tech sector (Research in Motion-Blackberry-Bill Gates comes to visit) but not so much nightlife as Vancouver! TO would be the main rival there. So I guess how much/kinds of nightlife are you looking for?
Waterloo is a university and college city so there is a "scene" going on. Housing MUCH cheaper there then BC or around TO-more bang for your buck. About an hour to TO with agriculture to the north of the city (but out of the city to city sprawl immediately surrounding TO-look at the main highway 401)). Many festivals and close to other cities in the golden triangle. Of course you could look around Toronto.
Ontario has much to offer active folks and nature enthusiasts. Different areas-different topography. That is a search in itself! People love Ontario's various beauty. Especially north of Barrie. But of course BC wins for sheer beauty. But you have to like rain-alot of it. You two would have lots of options I am guessing.
