I'm not 100% sure of the answer to that question, Mr. Masse. I'd say that this would be a question better positioned to Enbridge.
I can say—based on a previous question as well, looking for third party studies of the existing pipeline—that there are third party pipeline studies that have been done in the U.S. I'd be happy to submit those to the committee. The largest and most important third party validator is the U.S. regulatory agency that inspects the pipelines, which has given it a clean bill of health over the last 50 years. So that's really important.
