The understanding is that service obligations are terms related to the receiving, loading, carrying, unloading, and delivering of the traffic, which, as we explained at a previous meeting of the committee, is what is defined in section 113 of the act. The definition of service obligations is different case by case, depending on the specific situation of an individual shipper.
In terms of a mechanism for having a sense of the full scope of what it might encompass, there's lots of jurisprudence, through the courts, but in particular through the Canadian Transportation Agency decisions on section 113 through the complaint mechanism that shippers currently have under section 116 of the act.
