I'll mention two things. The numbers reflected a point in time and they're evolutionary. No one expected we were going to have a better rate on the U.S. dollar when those numbers were being done two or three years ago. So things change economically. To me, it's like a number up in the air; it's an aspiration. It's a need today.
The dredging situation I think is included. I think dredging is a conundrum for the program because we can only dredge within our own water lots. But a lot of our harbours are within other channels or other jurisdictions. So our harbour might be fine, but getting to it is quite difficult. We're not talking about numbers that are our responsibility. For instance, in British Columbia, I could spend about $2 million a year on dredging; I can afford to spend about $400,000. It gives you an idea of the risk we take just to maintain what we have.
