I think Steve might want to come in on the question regarding CUSMA, but in terms of looking at all our options, it's exactly that. As you may know, there are processes in state court in Michigan, as well as in federal court. We do see this as a state-to-state issue between the Government of Canada and the Government of the United States.
This issue was raised in the recent meetings last week to ensure that the United States realizes the importance of Line 5 to Canada, and we'll continue to look at all possible options going forward.
Steve, did you want to comment on the CUSMA aspect?
