Thank you very much, Ms. Liu.
I am going to share my time with Mr. Nicholls, so we're getting all our questions out.
Mr. Dutton, I just want to come briefly back to what you raised around the innovative pipeline strategy. This is a real issue. Pipeline safety in Canada is increasingly a matter of concern to a lot of Canadians right across the country. The whole issue of best practices and the lack of government regulation is something that comes to the fore.
Could you give us in a few words what you think the regulatory framework should be, so that all companies—and I'm thinking particularly of some of the bad apples that had spills that were caused through negligence—would have the same standard of safety applied and some of the good practices you're bringing would actually be current throughout the industry?
