actionmama.com — Just sharing a website where it is possible to find several brands not imported in Canada at affordable prices. Shipping is expensive (70euros!!) but i was able to negotiate it for a large group order (~2000CAD) Remember that prices include the VAT (22% at the time of this post ) and you should ask to remove it from the total! I am totally not affiliated with them.

mountaingear360.com — Affordable store that carries several products hard to find in Canada.

backcountrywater.com — Backcountry Drinking Water - a comprehensive, authoritative information on drinking water quality, contamination and health for hikers, climbers, hill walkers, mountaineers and travellers.
