Thank you for that question.
I should just note that while the United States is not subject to the Basel Convention, in order for Canada to ratify the Basel Convention, we had to enter into an arrangement with the U.S. to ensure the environmentally sound management of non-hazardous waste and scrap subject to transboundary movement.
I will turn to Nathalie Perron to give you the specifics with respect to the amount going to the United States, but it is a significant portion of our material.
