I think I'll answer that, given that it's more about a Canadian CBAM and how that would go hand in glove with that. It's a good question. Obviously, when we put the 25% surtax on steel products from China, part of the government's rationale was that there were lax environmental policies. I think that if Canada wanted to move forward with a CBAM against China, that's something that would really have to be better understood.
I think CBAMs, those that you see in the European Union, for example, are very much.... They're very technical. They're very detailed, and they gather a lot of information on the product-specific emissions contained within those. I think it would certainly be a larger administrative process to gather those emissions and to link them to a Canadian carbon price, whereas the surtax on steel and aluminum was more a measure that made the statement that these were problems and imposed the surtax.
