Yes, we're using rail. Rail tends to be used again in regional transit. So you have Metrolinx, which provides GOTransit service in Toronto, which is run over rail lines. Again, in Quebec there's heavy usage of rail lines for public transit, and it's less so in Vancouver.
In Canada, as you know, the rail system largely is privately owned, and to the extent that it's utilized in public transit, the public transit authorities, be they municipal or regional, have to enter into agreements with the two large operators, which are CN and CP, which own those lines. I'll let my colleagues at Transport Canada speak to this more, because they're in charge of this, but there's been a concerted effort in recent years on the part of the federal government to try to protect those rail corridors for transit in the future. But those assets at the end of the day are privately held.
