There are two questions in there.
First, I'd just like to say that most dangerous commodities, which we call toxic inhalation commodities—chlorine, anhydrous ammonia, etc.—today are not restricted to any location. Restrictions and regulations are being developed, as we speak, in the United States, and we're working very closely with Transport to implement something similar to that in Canada. So I think we can and are taking precautions with regard to handling dangerous commodities. That's number one.
Number two, with regard to community outreach, we see that as very important. In my remarks I said that we have an extensive outreach program. Last year we conducted approximately 30 tabletop exercises with various communities—not the same communities. Obviously we traverse some 900 communities across Canadian Pacific, and we're working extensively on a graduated basis with those communities to ensure that we know each other, the protocols, and the emergency responders, and that we do the training. We find that helps immensely.
It also helps immensely, by the way, on proximity issues, just because of the relationship we have. We actually conducted five to six mock disasters, which we do on an annual basis with various communities, again on a rotating basis, to ensure that we literally go through a very detailed mock disaster as if a real one did occur. Then we do detailed follow-up and an audit after that to make sure all of the parties were comfortable with how we reacted. It's a critical part of our community outreach on a go-forward basis.
