I will try to explain. In the cement sector, we favour a sectoral approach. Many discussions have taken place, and others are underway, in Europe as well as in Canada, at the provincial level. Because of the Western Climate Initiative, there are many discussions at the federal level in the United States. Therefore, we favour a sectoral approach.
As I mentioned, 15 million tonnes of cement are produced in Canada annually. Approximately 5 million tonnes are shipped to the United States. Hence, it is an integrated market. We are promoting the harmonization of regulations—federal, provincial and American—to foster trade and eliminate tariff barriers and taxes at the border in order to permit the free movement of goods.
