Mountain equipment coop is a good place to start (mec.ca). They have a decent selection of LM and victorinox and some others. Shipping is free for orders over $50 and that's really easy to do. Their catalogue is online and if you aren't a member there is a one time $5 fee.
Warriors and wonders in Vancouver (b.c.) has a big selection of knives and tools - shipping seems pretty reasonable - a search will give you their website.
