Indeed, agriculture is not exactly a service like the others, nor should it be. Your country is fighting to have its agricultural surpluses enter other markets. Thus, Canada is perceived as a country that wants to open the markets, but at the same time, Canada protects some of its own sectors. It is completely understandable, and we all do it, but it is a paradox, nonetheless.
When Canada asks one of its partners to open a market—and this is where the argument of the Canadian Wheat Board comes into play, although it poses no problem—it will come back to Canada to see what you are doing and to challenge Canada.
As a final point, I would say that fairness is the biggest challenge. I see no alternative to the WTO. Everyone here today can dream of a perfect future, but the WTO, where developing nations are the majority, is the tool that can help us find solutions. It is not a perfect system, but it is the only one we have. It is up to us to work to make it as fair as possible.
