Try www.sealsactiongear.com in Calgary. Last time I went in there was a bout six months ago, they didn't have any of the Olive drab paracord in stock but they did have white cord (I don't think it's mil spec paracord, it's much stiffer but I bought a 50-foot length to weave into a belt). They're a little bit too "survivalist" for my taste but they have some pretty good stuff and their website advertises in Canadian dollars.

I think if everybody who wants a Canadian supplier for the Doug Ritter PSP were to write to MEC asking if they had plans to stock it, they might consider it. I'm going to write to them in the next couple of days; if you write to them, make sure you point out that it's from Adventure Medical Kits, so they won't be dealing with a new supplier (AMK is well-represented in MEC shelves). Probably a traditional ("snail-mail") letter would be more effective than an e-mail, although I don't suppose there's any reason not to send both. <img src="/images/graemlins/laugh.gif" alt="" />
