The whole purpose of safety management systems was to enable companies to manage their safety risks, which they must do because you could never have an inspector watching everything that's going on. When we conduct our investigations, we always look at whether there were practices in effect that were non-compliant with regulations or unsafe. In cases of non-compliance, we look at why they weren't picked up by the regulator.
To date, what we've identified is more about the way Transport Canada was conducting oversight than it was about the number of inspectors that were available. In other words, there were situations—in rail, air, and marine—in which Transport simply didn't pick up on unsafe practices, even though they were doing inspections.
