Mr. Volpe, I would invite you to comment on something that we've heard repeatedly. To borrow Ms. Cobden's phrase, because I thought it was an accurate one, climate policy is now trade policy. You talked about the fact that since Confederation, we've always been dealing with this economic titan at our southern border. I think that's right, but I think the environment has entered the equation now, and there's an alignment.
Can you talk about what that holds for the future of our discussions nation to nation? How do we emphasize, when we're dealing with those meetings with American senators and congresspersons, how economically viable and environmentally sustainable Canadian industry is?
