Pearl Milling is Canadian. I've been using it since the first tariff wave. It's just as good. Yes, I'm back to turning "Product of USA" upside down.
Pearl Milling Company is a brand owned by PepsiCo, so I don't think it's any more Canadian than the others?
No Name and President's Choice being the Loblaws store brands would arguably make them more Canadian (though the companies making the white-label products might be American).
