To be clear, Mr. Chair, they are contributing to some occurrences but not all; I don't want to say all. Certainly in some cases they are. Some of them are ongoing, and when these reports are issued, you will certainly see how Transport Canada oversight has been a contributing factor or has created a risk of such accidents.
Certainly that was evident in the Lac-Mégantic investigation that we released in 2014 based on the 2013 accident. Again, in fairness to Transport, they've come a long way. They've done a lot of things, but we are still seeing some issues in some reports, so we continue to look at that and to either make recommendations or keep it on our watch-list.
