Well, again, if I speak to Lac-Mégantic, Transport Canada was aware of weaknesses in MMA's ability to manage risk, but they were unable to change how that company was operating, and so those unsafe operating practices persisted.
We've seen in other modes cases in which the regulator has not identified instances of non-compliance or unsafe operating practices. That's one of the reasons we put this on our watch list in 2014, the notion that companies should be responsible to manage their safety risks and that the regulator has to make sure that their SMSs are effective and find ways to ensure that companies are able to effectively manage risk so that unsafe operating practices don't continue.
We haven't identified, in our investigations, specific instances in which that didn't happen because of a lack of resources.
