I think when we look at border management generally in the Great Lakes region, we still see areas, whether regulatory co-operation or customs co-operation, in which we're not doing as much as we could be. On the regulatory side, the more we align and eliminate duplicative regulations, the more we create clarity for businesses on both sides of the border and the more we speed up business across the border.
Again, on more of the customs facilitation side, it's a matter of recognizing that there's a security element to customs facilitation as well as a trade facilitation component, and of making sure that we have the systems in place that can do both.
