Minister, you mentioned that 99.997% of all shipments in all modes related to the transportation of dangerous goods make it to their destination safely. When you look at Lac-Mégantic and Gainford, it's obvious that the 0.003% can in fact be devastating. Can you talk about some of the actions being taken to improve rail safety in Canada? Specifically, again, I think what's important is the reiteration that directives and rules, once confirmed and accepted, carry the force of regulation in this country.
