The parallel, as I mentioned, is what is proposed with the ship-source oil pollution fund, borrowing money in excess of $1.4 billion of liability for cleanup from the Canadian consolidated revenue fund.
The recovery of that money in the case of an incident involving oil would be a levy on oil imports and exports, and the recommendation is quite clear on that point. In terms of recovery, potentially, if the government were to decide to go in this direction on other substances, it would be a similar mechanism to recoup any expenditure, and it could be a levy on those substances in terms of their transportation through Canadian ports. There are many options open, actually.
