Great. Thanks very much to the witnesses for being here.
I have a quick question on transportation. Maybe Mr. Walker could comment. I would also like to get Dr. Fraser's opinion, because he's mentioned that transportation is important.
Recently I found out that the delta for a train to be on time is about four hours. If you're four hours before, you're on time. If you're four hours after the time you've set, both companies that are operating in Canada say you're on time. Are they actively trying to work with your members to reduce that delta so that they're on time? How does that compare to the U.S., for instance?
We know there might be strike potential in the U.S. as well. We often hear about CN and CP, but I don't know what's happening in the U.S. If you're talking to some of your counterparts in the U.S., what's the relationship down there with the rail companies?
