If I may, I think the leaders established the process in 2005. It was a very public process. It was made clear from the beginning that the intention is to move forward, as Mr. Campbell suggested, not through any great leaps but in very practical, incremental ways. Last year, in establishing the North American Competitiveness Council, leaders essentially recognized that areas like regulation and border management are highly complex, and given the sprawling number of potential items for action, they would benefit from advice from those who would be most directly affected.
In other words, if you have a limited amount of time and attention that a government can bring to a broad agenda, you want to look at what actions we can take and how best we can use time and resources that are available. In serving those outcomes, the governments have decided what advice is going to be most useful. It seems to me that if you're dealing with issues of the nature that are being dealt with under the SPP, leaders simply turn to ask for advice from those with the most relevant expertise, and that's their option at any time.
