That's a good question. They didn't have any system in place, as I've just mentioned, for the aircraft. They were doing inspections on some trains and on some marine vessels, but we've also noted that there were gaps in terms of the coverage and sufficiency. Do they know how much is sufficient in terms of inspections? What we've said is that there are also some gaps there. Do they have a clear perspective in terms of how many times you have to go and inspect those trains and marine vessels?
On the trains and marine vessels, we've also noted some gaps. Part of that is how often they have been inspected. What we've said is, for example, on the trains, we've noted that there was a low level of inspections in proportion to the number of Canadians who take trains.
