My view, as an economist, is that if we're concerned with the well-being of all Canadians, all Canadians who eat, drink milk, and so on, we should have more open markets and we shouldn't have supply management. From where I live, I see lines of people regularly going across the U.S. border, to buy cheaper dairy products and so on. I think that Canadian farmers would adjust if we had freer trade and less supply management. I think the government said they would help with adjustments both to this and I imagine anything further, though they're not talking about removing supply management yet.
But as an economist, I prefer freer markets to supply management. It helps certain producers at great cost to the majority of consumers.
