Perhaps I could switch gears and go to another issue, which is the question of third party liability.
Since the accident in Lac-Mégantic, a lot of Canadians have been asking questions about who is responsible, who ought to have known, and who is responsible for the cleanup. We really have no idea and, to our knowledge, we have no real idea what the long-term costs of this are going to be. We have no idea, for example, what the ecological and environmental costs and damage will be in the waterways that have been affected.
Many Canadians have written to me asking this committee to look at third party liability and have gone as far as to say that liability has to be shared. They have mentioned bringing into the tent those who are importing, those who own dangerous goods. For example, if an oil refinery is importing diluted bitumen, or in this case, Bakken crude, and there's a problem and a major accident, then liability should be shared not only among the federal government, the provincial government, and the railways, but also with the owner of the crude in that tanker. Have you looked at this issue?
