The only thing I'll add is that the SMS audit is an opportunity for continuous improvement. It's an opportunity for continuous improvement through the audit to the inspection reports that are put forward by Transport Canada, and also the railway companies' doing regular check-ins and making sure that their safety management systems are robust and are meeting the needs of their employees and its customers.
I would say that continuous improvement is certainly an ongoing opportunity, and it's an opportunity the railways take full advantage of as well.
