Chair, I'm just going to ask people not to interrupt, because I'm trying to make a point here.
My question of Mr. Layton was, “Have you costed your plan?” And he said, “This is a set of targets. It will be up to the governments of the day to advance plans and figure out how we achieve these targets.”
So my question is, how important is it to have this costed so we know it's realistic, keeping in mind each country has unique situations? I believe we have very, very aggressive targets. Bill C-377, which we're talking about, and that's what you're here for, has not been costed.
I asked Mr. Bramley the same thing, or I think one of us asked him. He also said, no, it hadn't been costed. Both of these witnesses have said they were hoping the government would do that.
How important is it that we cost this so that Canadians, so that this government, so that each of us involved, are going into this with our eyes open? How important is it that it's costed?
