It's not about safety but about the transport of dangerous goods, as you said. Bill S-4 will cover a lot of things.
With regard to the environmental issues, as Mr. Bourdon said, we'll have better tools. For dangerous goods, we will follow what the Auditor General said about that. We will continue to have better results, and we'll continue to fix that.
Mr. Bourdon, do you have some words about that?
