Sure.
One of the things we're facing right now is whether or not Canada is going to have to give on its supply-managed sectors in dairy and poultry, and whether or not Canada is willing to give on supply-managed sectors in dairy and poultry.
In my personal opinion, these are policies better suited to the food security needs of wartime than a competitive North American exporting industry, but that is a public policy decision for Canadians to make. If we are spending so much time defending the interests of these sectors, it's very difficult to go to the same negotiating table and say that now we want strong access for Alberta beef, for wheat, for grains, and so on.
Also, the things that Canada does need in terms of stronger access in service industries, in consulting services, engineering services, any place we can put our brains to work and deploy our skills elsewhere in the world, are key growth sectors for Canada. But if we are deploying our negotiating reserves to defend old-school sectors, or stepping out of the TPP entirely, which we may have to do as a result of our defence of supply management, we have no opportunity to promote those high-growth sectors.
Also, I find—again, in my opinion—that our trade policy tends to be Ontario-Quebec centric, and does not pay as much attention to western Canadian—British Columbia, Pacific, Alberta—interests as it could and should.
