Why? Because of a crazy marketing system controlled by the dairy industry, with government backing, that regulates how much milk you can produce. You even have to pay for the right to produce milk!
When we lived in Boston, we enjoyed Chobani Greek yoghurt. Chobani was going to build a plant in Ontario, but has been prevented from doing so by Canada's ridiculous quota system.
Canada should dump these stupid marketing boards that drive up prices for consumers and prevent innovation.
