The list of factors that an arbitrator must consider captures the individual shipper's needs. It also captures the fact that the railway is obligated elsewhere in the Canada Transportation Act to provide service to all shippers. The goal there is to ensure that the arbitrator is really considering the individual shipper's requirements and also taking into account the fact that the railway has a broader obligation to provide service to all shippers. What that means in practice is making sure that it can operate an efficient network for everybody. Both of those factors are there to try to come up with a solution that allows the railway to operate the network and still provide individual shippers who have asked for an arbitration with the service they need.
