We operate 20% of our network on CN or CP tracks. Under the Railway Safety Act, we are designated as a local railway. Transport Canada can come directly to us, should it need to, which we actually do encourage.
I think you're talking about dangerous commodities. We do work with the railways. We are below the threshold level set by Transport Canada for dangerous goods, so it's not a high issue for us. It's not a lot of stress for us. Notwithstanding that, we understand that there are other agendas that would want to look at the routing of dangerous commodities and what's best basically for urban Canada.
Those are higher level conversations, and they're not easy ones to have either.
