We invest about 20% of our revenues annually. Derek mentioned 12%.
The projects that we have under the national trade corridors fund.... We've done a lot of coordination, as has CP, with the port of Vancouver. They've been very good about that. Our biggest issues are when we get toward the end of the line where we have five railways, urban encroachment and marine traffic influencing the utility of infrastructure because bridges have to open. This is where it becomes very complicated.
In the case of the north shore where the federal funding is going, one of the reasons why it's very difficult to put together a business case to fund $200 million for a capacity improvement is that, through federal legislation, we have to provide service to CP's traffic for a very low rate. Also, a good portion of the traffic on the north shore is regulated grain traffic, so the return on investment is extremely low. We see the availability of that fund as an offset to those things that are imposed on our ability to generate a return.
