I understand that. I just wondered if you've heard about some instances where that may have happened.
I'm going to ask Mr. Romoff a question.
Mr. Romoff, in Vancouver we experienced the very successful Canada Line, of course, as I think you mentioned in your comments. How is this being shared across Canada in terms of a way to build that saves taxpayers' money and also manages to bring in a pretty substantive project on time and within budget?
