For the longest time, Vancouver was the only attempt of a big city in BC. Then Surrey, Coquitlam & Burnaby started to be more like a big city. Victoria remains as a provincial backwater, that isn't allowed to rival Edmonton, Winnipeg, Quebec City or even Halifax. Yet, Victoria is the most mild city in Canada, but the local power-structure continues to hold back Greater Victoria. Kelowna is the main city between Vancouver & Calgary. Now it really has a chance to eventually become another big city in BC.
Alberta just isn't under anything like the BC control system, So Calgary & Edmonton are able to be much bigger cities than Vancouver.
