Having been given that great introduction, I'm not sure that I am able to answer that question.
I would say, however, that one of the reasons for the Ottawa Group proposal is to ensure that those types of things, hopefully, will not happen and that through trade facilitation, through the relaxation of customs, custom duties, tariffs and export restrictions, these goods will flow much more easily.
I don't know whether any of my colleagues who are here can speak more to that particular issue.
