Not in Canada, but Nick Hulme of Magic 9 Design in the UK sells parts for the CO2 guns and his piercer seals in particular make the stock seal seem as useful as steel Crappy Tire Winter rims on a Bugatti.
Night and day difference in my CO2 mags for my KJW Les Baer 1911. I believe he sells a myriad of other parts as well.
