In terms of Port Metro Vancouver, our structure is slightly different, although it has the same principles as were described by our friends up north.
Our arrangement is that we've entered into memorandums of agreement with both railways that seek from them a commitment to enter into service-level agreement with individual terminals. We aren't directly party to those service-level agreements.
The memorandum of agreement also outlines responsibilities in terms of collaboration around performance monitoring. That's the primary role the port undertakes to assure ourselves that the intent behind the language is followed through. There's an escalation provision in there that suggests that if we do not see performance in response to critical issues, the various representatives of the firms—terminal, railway, and port—at the most senior level will meet and discuss those issues.
That's the basic structure in Vancouver.
