I think that's a great question that you should also ask Transport Canada. They're the transportation experts. They should try to find a way to properly measure the system's effectiveness.
I certainly agree with you that it's probably not a single metric that would measure the overall effectiveness of safety oversight activities. We mentioned earlier that we could look at compliance rates for certain acts or regulations and compare them to the number of accidents. We could then see if the compliance rate is increasing while the number of accidents is decreasing. We could see if there is a direct link between the number of accidents and the increase in the compliance rate.
This is really an area that all companies are interested in, as well as all departments and governments. They're all trying to measure its effectiveness. Just because it's difficult doesn't mean that we shouldn't do it. We must measure the results of our interventions.
