Figured I’d contribute with resources I’ve used and found really solid, not everything is made in Canada but all are Canadian businesses with fantastic customer service.

Filament

• Matter3D Langford BC based manufacturer, they make some solid quality filament and promote themselves as engineering grade material. Their abs has low odor, petg prints really well, haven’t tried their nylon yet but I have a few spools to work with. Their prices are extremely reasonable and they have regular sales, my go to supplier

Parts, kits, etc.

• Spool3D Calgary AB based store, Canada wide through canpost for free over $140. I live in Ontario, but most of my purchases are from them, solid selection of material, parts and accessories. My voron was sourced with parts 90% from here, they also have solid filament, sell garolite sheets too for a build surface (trying to move away from using builtak, they’re a solid product but I won’t be buying American for the foreseeable future)
• 3d lab tech another in Calgary, the other 10% of my voron came from here. Lots of kits and high quality parts, highly recommend, extremely responsive too and they constantly have new, interesting stuff.
• Sparta 3D Brampton Ontario based, again, lots of kits and high quality parts, have quality filter carbon as well if you’re looking for a good Canadian supplier of acid-free material. They have filament as well, haven’t had an opportunity to use it yet however.
• Makerparts they’re moving so unfortunately site looks to be closed for now, BC based, they’re all sorts of maker related stuff, not just printing. I bought a bear mod kit for my prusa from them, again, solid product and great to work with.
