Currently, as I mentioned, the railway operating certificate will be defined by a regulation, so we don't know yet what that will entail. We have to consult with all our stakeholders to get the input from companies, unions, on what they'd like to see in it.
On the environmental side and what they currently have in place, basically, other than a certain environmental assessment infrastructure project, we don't have much in the Railway Safety Act that deals with environment. When it comes to dangerous goods, it's under the dangerous goods act and the dangerous goods directorate at Transport Canada.
I know there are usually multiple jurisdictions when these things happen, where the federal, provincial, and municipal governments may show up, so I don't quite have an answer for that at this time.
