That's a very difficult and complex question. My response would be this. For shipping we already have international conventions that deal with oil pollution from tankers. You do have strict liability of shipowners up to a certain amount. Then there's a fund convention that has contributions from the oil industry globally that would also kick in. There's another protocol to that. The total coverage would be around $1 billion. There is a lot of money there already. And Canada is party to these conventions, including the supplemental protocol.
I think for shipping we're in pretty good shape. It's more with the oil and gas field that you might be more concerned. There, again, liability is a lot less, in terms of under our national law. Then again, if you look at the National Energy Board, which does regulate oil and gas activities in the offshore, a recent report—about a year ago or so—talked about, again, how they are going to work out case by case the financial security that oil companies would have to have in place.
It seems to be quite a case-by-case basis, as I understand it. There's no global convention that deals with liability from oil and gas spills. There's no regional convention that deals with liability and compensation from oil spills from rigs when they're in the offshore.
