If you ever come to Montréal you can find Photon Microlights at Le Baron (8601 boul St-Laurent, Québec) and you could visit MEC which is situated in the same area (8989, boulevard de l'Acadie) and they have Katadyn Micropur tablets (if you want to upgrade your water purification) and Doug's PSP if you want to get a sightable signal mirror and many other quality items for only 28$ CAN. Note that there's a MEC in Québec city at 405 rue St-Joseph Est, Saint-Roch.
