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.

Not really self promotion but a couple family members started a small shop in Eastern Ontario. I helped set up the site a couple years ago.

I have a list that I just started on my phone of Canadian products to put in an eventual master list post on this community. I’ll add that link to my note
