I second the J&L and King Ed votes. I did a full day tour of the city's stores a year ago. There is a great article on the web, a Vancouver hobbyist lists every store in the region, and even gives a brief description, and a map. I can't remember the link, but I think it's bookmarked on my home computer. I'll check after work (Google will likely do the trick tho, it may be linked to a Vancouver aquarium club website.)
