They're significant. We shouldn't pretend that this can be done without a good deal of negotiation and hard work and perhaps some further regulatory and legislative measures, especially in the United States. But what I'm pleased about is the very clear statement by both the Prime Minister of Canada and the President of the United States, when they met at the White House a few weeks ago, saying that this is a priority for both countries and they intend to get it done. It wasn't just a statement of objective, hope, or ambition. The two leaders committed themselves to getting this work done.
There have been some pilot projects that have been tested out to identify the kinds of issues that would have to be dealt with, so there is some work under way, but more needs to be done. I think, with the enthusiastic support of business leaders and exporters on both sides of the border, we can keep the momentum building toward a practical, effective solution.
