As I mentioned, Canada recently entered into an arrangement with the United States, with respect to the management of wastes that are destined to the United States for final disposal. With respect to waste that's transiting on, that material requires an export permit and it requires an export permit in Canada.
I think we will need to continue to make sure that we're diligent in terms of making sure our industry complies with its obligations and that we continue to work internationally with partners with respect to these issues.
