Here’s some links to websites which list products made in Canada. Please note I have not personally created these lists and there may be issues (e.g. made in Canada from an American company), so it’s best to still do your research. I will eventually have a list of my own for 100% Canadian brands, organized by product type, but until then you can use these lists to help you. I may add or remove lists from here as I see fit and based on community complaints/requests. This is definitely a work in progress still so please be patient, but also please do give me any feedback you can so I can improve this list.

Most Canadian bicycle brands import their frames from the far East, but Devinci actually makes them in Canada. Now if they would just pick more appealing colour schemes. (No, I don’t work for them. I don’t own one either, but I would consider it it I were in the market for a new bike.)
