I don't know what details may occur in private, but the public indications are that there have not been, at the ministerial level or at the secretary member of cabinet level, sufficient representations.
My understanding is that there are not adequate enforcement resources in the area. There's a recognition now that there's a problem, but the products are going north to Canada, so I think they're less sensitive to the importance of moving quickly, and I don't think there's necessarily a full appreciation of the magnitude.
I know there are different fora where members of Parliament or government representatives can raise this. I believe that when the full story is told, the Americans will agree that it's very much in their interest to find a solution to it. They have different enforcement options, they have different technologies, there are different approaches, and the Americans can help figure out what would be an appropriate way, including consultation, to deal with this.
