Hi,
I am looking for a place to purchase C02 in the east end. The only place I know of open on the weekend is JT's Military Surplus (paint ball shop) but that is out west.
Somwhere near the downtown area or an LFS that sells C02 in gas form (excuse to buy more livestock :D) would be ideal.
Davidson fire extinguishers downtown.....I think they're on Gilmore.
Davidson's a bit more expensive compared to http://www.pyromateck.ca/ in gatineau. Both are only open weekdays during business hours. The paint ball shop way over charges imo.
Plus one for the place in Gatineau. I was going there usually but didn't mention it because you wanted something in Ottawa. If you're in Gatineau for something else worth getting your refill there. You'll definitely save a few bucks.

Thanks to all, I am going to go to Davidson's tomorrow!
