Let's be practical. When the TSB issued its unprecedented release in partnership with the American NTSB, never been done before, effectively calling for the urgent transition to new cars, presumably the American regulators are seized with this, are as concerned with this as we are. I'm sure Lac-Mégantic transcended our border, and all kinds of other incidents, as our colleague from the union mentioned, have led people to focus their minds on this. But is there anything practical stopping Canada now from saying that we're going to move to a higher standard of car for operations in Canada? After all, we're still a sovereign state.
