Just before I recognize Mr. Lemieux, we are running a little bit tight on time, as other people have other commitments.
My experience has been, as a chair, that estimates pretty much are an open field. I've never seen anybody shy away from taking the minister on when they have him there. But we also know the difficulty, and you both alluded to it: it's tough to get ministers without a schedule, and with the ministers' schedules, again in my experience, they book a long way into the future.
Mr. Lemieux.
