Okay. What it does is it leads me and the investigative staff to ask the question, is there any commonality between these accidents? What we have found is that you have to get into the investigation, look at what happened and why it happened, and look at the safety deficiencies in the system. What are the underlying factors? You have to do that methodically for each one, before you would ever arrive at the point where you could determine if there was any commonality.
So with the ongoing rail investigations, with Wabamun Lake, Cheakamus—there's a number of others—that's what we're doing. With McBride and Whitby, that's what we did. We investigate each one and look at it in its entirety. If we see some kind of common thread, then certainly we would bring that to the attention of the Minister of Transport.
