I'm going to turn to my officials for the first part of your question. I have to compliment you on your detailed knowledge of this bill.
On the issue of dangerous goods, the decision was taken with respect to transporting materials that could involve toxic gases. The LHI exclusion is based on the fact that one wants to minimize the handling.
Now, your point is that there are other dangerous goods. The decision was taken that at this point we would restrict it to toxic inhalation materials. It's something that certainly could be looked at, but for the moment, that was our primary concern. We recognize that there are other dangerous materials as well.
On some of the lines that are very congested, where there's a lot of traffic and there are dangerous inhalation products, we want to minimize the chances of accidental releases, which do unfortunately happen in the present circumstances.
