The second question is based on the notes you distributed and spoke from, Ms. Tadros. It deals with the SMS. You say that the SMS is a very good tool that helps to mitigate steps in advance. Then you go on to say that you have serious problems with respect to the way in which the safety management systems are overseen by the regulator, Transport Canada. You talk about the need for audits and for strong regulatory oversight. You cite the Auditor General's report. I think a lot of Canadians get it; they understand that there's a partnership between the regulator—the government—and the railway companies.
How far are you willing to go? What else are we supposed to do here in this committee to strengthen regulatory oversight? What can you offer up here for our advice?
