The U.S. has proposed that all products in the production of an automobile be subject to tracing. Under the current NAFTA, there was a list of products that are subject to tracing, and the others are not subject to it. Subjecting all products to tracing would increase the costs to auto manufacturers considerably, because documentation would have to be provided at every stage of the production process, and it's not clear from the U.S. proposal how far that would go back in terms of the origin of any kinds of products that would be used in the assembly of an automobile.
We think the proposal as it stands is entirely unworkable. We will be talking to the U.S. further about the whole tracing idea. Manufacturers, both in Canada and the U.S., have made it clear that they also think that particular proposal is unworkable. I think it will have to be significantly modified before it can become a realistic consideration.
