I am in Vancouver also and ride on/with the Mighty Riders. They are about the only "old school" lbs left in Vancouver, a little gruff, a very eclectic variety of bikes and parts (as opposed to a store that is all one brand like Trek) and the best mechanics in town, they will NOT kiss your ass but they WILL tell you what you need to know.
John Henry would be more convenient if you are in NV and they have excellent customer service. I did a photoshoot in their store for one of my clients (Brodie) and they were so nice that I bought a bike for my son from them.
The Argon bikes are very nice, good luck!
