It's very difficult to know sometimes. The Army Corps of Engineers and the organization—whose acronym I forget—of governments and mayors on the U.S. side just commissioned a study, and none of the Canadian numbers were included in it. So it's not at all clear to me that the numbers that are put forward are comprehensive at any point in time.
I've heard numbers for annual impact considerably higher than that. It's a bit of a mug's game, I think, to try to put a dollar value on it.
It's a lot of money to us. Speaking on behalf of our industry, it has clearly had a profound effect on the viability of our industry for half a century or three-quarters of a century.
