If I could interrupt here for a moment, Madame, we didn't ask the witnesses to come here today to get challenged on their points of view. We asked them to give an economic impact of the oil sands. There will be other witnesses who will provide some of those things you're asking for. But that was not the intent of this meeting today, nor of the groups that are presenting today. They were asked specifically to give the economic impacts of the Alberta oil sands industry. They're not on trial here; they came to give us information and to present the point of view.
I just wanted to clarify that.
