I'd like to highlight the approach we take to safety at Transport Canada. We've built multiple layers of defence against any rail accidents, especially those involving dangerous goods. For example, we have measures in place to help prevent accidents from taking place. We've talked about some of those, including train securement rules, track inspection rules, key trains and key route rules, all of which were put in place post Lac-Mégantic to help prevent accidents from taking place.
It's not enough just to put the rules in place. We also need to oversee them. Again, we have a very robust oversight program that goes out to make sure that railways are following the rules. I've mentioned the fact that we do about 35,000 inspections per year on the rail side and 4,000 on the TDG side. That's all about making sure that companies are operating safely.
Above that is an additional layer of safety. We have new, enhanced safety management system regulations in place. These are requirements that go above and beyond the basic regulatory requirements. They require operators to have systems in place to identify, assess and mitigate hazards above and beyond what we require from a pure regulatory point of view. We oversee those as well.
In addition, we have in place measures to help first responders mitigate or limit the impact of accidents when they do occur. These include stronger tank cars to protect them, as well as information for first responders and communities through which dangerous goods are brought.
We're always striving to improve and we're not going to stop striving to improve, but we do think we have very robust layers of safety in place.
