I tried to get on with this “Buy Canadian” protest. But ketchup, a basic north American staples far as I’m concerned, has no major Canadian only manufacturers. The only stuff you can find is boutique stuff that’s like 10 bucks for 500ml. and you have to have it shipped to you.
This is really only a solution if you have freezer space or storage space and free time. Also homemade ketchup often sucks. Most people are not capable of making a half decent ketchup.
