Actually, there are four remaining recommendations relating to the Lac-Mégantic accident. I cannot say one is more important than the other.
First of all, tank cars transporting flammable liquids, such as crude oil, must be stronger. We know that regulations are in effect, but we are concerned about the timelines because we might have to wait until 2025 before all the deficient cars are withdrawn.
The second recommendation pertains to risk analysis. We are waiting to see if this will indeed be effective.
The third group of recommendations pertains to prevention and ways of preventing runaway cars.
The fourth recommendations pertains to Transport Canada's oversight.
I could not say that one recommendation is more important than another. They are all important since a range of measures is needed to reduce the risk of another accident like the one in Lac-Mégantic.
