I have said many times that if it's not working, we will make it mandatory. I have told the provinces that; I have signalled that to industry. We are obviously keeping a close eye on this, and if we feel that it is not sufficient....
It was an agreement among the multi-stakeholder committee that this would be a voluntary approach, but I've told everyone very clearly that from the federal point of view, if it is not working effectively we will move to a mandatory system. I can tell you that we have already begun formal consultations.
