You mentioned $600 million plus in income tax next year that you'll be paying to the Government of Canada. That must reflect some commercial success. You would want us to take some of that income tax that flows back to us to invest in infrastructure, and I agree that investment in infrastructure is something we hold quite dear here.
At the same time, I think that reflects a commercial success that we, as a committee representing the interests of the public of Canada, have a right to look at and ask what responsibilities the rail line has to meet public interest objectives, in the same way that you would expect us to invest our $600 million wisely in a way that is supportive to you. I think that cuts both ways in terms of our asking the railways to meet certain standards.
For instance, on health, there has been quite a discussion around the health issues related to noise and so on. Many of the communities that were here spoke to that. They spoke of World Health Organization standards and so on. What research do you have that counters that in terms of the health risks, or is that just a risk you're prepared to have Canadians accept?
