In a nutshell, what it boils down to is the test of adequacy. Adequate for what? As we embarked on this, we came to the realization that the system that is in place and managed by CTA could be improved on a few fronts, but it is adequate for day-to-day operations.
There is nothing in place for catastrophic incidents. Why should this be financed by the whole continuum? It's simply because this is a societal risk. The transportation, the use of dangerous goods in our society, is something that we all partake in, we all benefit from. The risk is created by the entire sector, not just by those carrying the goods. In fact, those carrying the goods will probably tell you they don't know how their goods are packaged necessarily. They can't be 100% sure that the shipper or the importer or the broker is telling them the truth as to what is in there, or what the qualities or characteristics of those goods are. It makes sense to us, from a policy perspective, to have everybody who contributes to the risk—on the polluter pay or risk pay principle—to contribute to that fund in some fashion or to recognize that they have a role to play.
There's a policy reason there, and there's a financial economic reason as well. If you put this entirely on the carrying sector, the railways themselves, most of the short lines will not be able to carry that burden. They can only purchase what they can purchase on the market, and the market will only go so far. The market will not cover Lac-Mégantic. The market will not cover Mississauga, or heaven forbid, the next one that will happen in 40 years. If we agree as a community that this is not something that should be carried by the taxpayer and the public purse, which is what's happening in Mégantic, then we have to create a system that is bearable to the sector, and spreading out the pain seemed to make the most sense economically, and it has a solid policy basis as well.
