The WTO is about trade liberalization and tariffs coming down, and every commodity will have to adjust to the new rules of the game.
Let's put it in perspective from my point of view. I grow corn, soybeans, and wheat in southern Ontario. I sit about 250 kilometres away from the American border. The United States subsidizes their grains and oilseeds sector to the tune of $15 billion. That product comes across into Canada with zero tariff: no over-quota, no under-quota, no peaks, no caps, nothing--zero percent. That's what I compete against on my farm in southern Ontario.
So when you talk about a common end point, the goal of the WTO is eventually to have zero tariffs. That's the common end point.
