Yes, absolutely. The system that was imposed in the original amendments to the Canada Shipping Act, which brought the spill response regime under the control of Transport Canada and the federal government, is where you first start to see this polluter pays program implemented. With the measures that the government introduced in May, what they're trying to do is to strengthen that program.
There are three levels to the liability. The shipowners have to have a liability and they're required to have insurance that covers that liability. Transport Canada is responsible for checking to see that those certificates do exist. That liability depends on the size of the vessel.
Once that is exhausted, there is international money available. That's about $1.14 billion. Once that's exhausted, then the Canadian fund kicks in. Initially that was up to $161 million. The government made recommendations that entire fund would be available for up to $400 million. Barring that, if we go past that, the government has also proposed a levy that's reintroduced onto industry to recover any costs that would potentially go back to the taxpayer. Right now you're looking at $1.5 billion available in case of a spill.
