It depends on the contract established between the two. If CN is no longer using the entire line and it rents it instead of selling it, it will depend more on a clause in the contract than on a clause in the bill. If CN says that it will continue to own the line and maintain it, but that someone is operating on that line, at that point, it would be CN who would be responsible for the maintenance.
I want to answer the question that you asked: why were they not exempted? One of the things that the panel heard from some of the people responsible for these commuter trains is that they wanted to be able to establish their own rules with the minister, and they wanted to request exemptions to the existing rules.
At the moment, they must conform to the rules of Canadian Pacific and Canadian National. In some cases, they determined that these rules were inadequate. They came to see me and said that they wanted an exemption to that kind of rule. We had to respond that, since their railway was not under federal jurisdiction, they could not request an exemption or establish their own rules, and they would have to negotiate with CN and CP, who had to agree to present an exemption to us. In a lot of these cases, this didn't happen.
One of the reasons we included them was to allow them to be able to make their own rules. That's what they asked the panel for and it's also what they have asked me for in the past, particularly AMT.
