N, I'm not Canadian nor a Vancouver resident, but I travel there somewhat frequently.
Usually I do my shopping downtown. I like to hit up Zara (on Robson street) because there isn't one in my home city. Some of Zara's clothes are out of my price range, but I have also found great deals on blouses or basics there. I also like to check out the Pacific Centre Shopping Mall downtown because I like the mixture of stores. There's also a great thrift/consignment shop downtown that carries very fun vintage pieces. I can't remember the name of the shop, but it's at basement level near the Robson/Granville intersection.
I look forward to hearing Brianna's recommendations!
