Mr. Speaker, as mentioned, Canada is a key NORAD and NATO ally. As the number one purchaser of American steel, any trade restrictions on Canadian steel and aluminum are unacceptable. This industry is fully integrated, and of course, it provides enormous value-added to the North American manufacturing supply chain. Should restrictions be imposed on Canadian steel and aluminum products, we will take, and reserve the right to take, responsive measures to defend our trade interests and Canadian workers.
