Aqua Solutions in Boisbriand and Benson Pools if ever you're in Ottawa. Lowry and Associates in New Market, Ontario is the official 'importer' and they may point you to other sources. While you have Michael on the line ask him why the stuff is so expensive here.

There's a very considerable difference in prices between getting stuff from US as opposed to Canada. Examples

R-0013 2oz, 11.65CDN vs 7.19US
DPD powder 10g, 24.95CDN vs 11.49US
DPD/FAS drops, 0.75 oz, 31.95CDN vs 18.99US (!)

Full disclosure: As soon as the paperwork is filed and processed and it's official I'll be carrying the Taylor line. I'm a bit north of Laval. I'll update my board signature here too not to worry.

Don't bother looking at Club Piscine, Trevi and the others, the staff there don't even know what a 'DPD' chlorine test is. They think it's a brand name.

Best thing to do though if you're not in a hurry is get it through the 'net. Some companies will ship to Canada (intheswim.com is one). Avoid getting refills on eBay.
