Again, our role is not one of compliance monitoring. That's Transport Canada's role, as the regulator. They conduct inspections and audits of railway companies, and other companies in other modes, that are required to have safety management systems. Where they identify non-conformance, they take the appropriate action.
However, when we do an investigation, we look at whether the company had a safety management system. Was it required to have it? Was it effective in identifying the hazards that posed a factor in the particular occurrence? If not, why not? Was Transport Canada aware? What action did they take?
A good example of that is our investigation into the Ornge helicopter accident in northern Ontario that goes back to 2013, which we released a little over a year ago. We look at it as part of an occurrence, but in terms of looking for compliance, that's Transport Canada's role.
