I'll start the answer if I may, and then I'll turn it over to Monsieur Chouinard.
Again, the fundamental issue for us there is risk assessment. When you are overseeing a system to make sure it's operating safely, it's important that Transport Canada has good risk assessment so it can focus its work on the areas of the most importance.
To be able to assess risks, you have to have data, you have to understand the environment you're working in. As for whether we noted any specific data as missing, I'll ask Monsieur Chouinard to respond to that.
