If it helps any, I know that the Low Carb Centre (from North Vancouver) is soon opening a new store downtown Vancouver, then one out in White Rock. Not sure the exact date for that though

If getting to Blaine is doable for you, I highly recommend it. We usually make the trip once a week or so, and find some really good buys there. They have the BEST low carb bread there (no kidding!), cheesecakes, mixes, L/C candy, pop with Splenda, TASTY pork rinds (if you can believe it!!), etc. I know other people make a day of it, but we usually just to go Blaine, the Pac Hwy crossing, takes us 15 minutes, the stores are right there, home again in less than 2 hours. Just make sure on your timing, or else the border can be a bit of a wait.
