That's part of our consultation with our colleagues in the U.S. As you can appreciate, these cars move all across North America, so it would become very difficult for us to regulate a phase-out unilaterally, but this is one of the aspects, in addition to designing the new standard. As Madame Dagenais pointed out, one of the other aspects is what would be a reasonable phase-out period for the existing cars, and also whether or not there should be any restriction on the types of goods they might carry, if some older existing cars remain in use.
