I heard Mr. Champoux, in the way he presented it, describe it as a way of removing any doubt about this fact. I think that's a fair way to characterize it. I pointed you toward a section at the beginning of the act that already talks about the act being applied consistently with freedom of expression.
You are correct. The committee heard from ministers yesterday that, at the end of the day, the CRTC is indeed bound by the charter, as you point out, and could be subject to a charter challenge if there was ever a question about one of its measures not being consistent with the rights and freedoms guaranteed by the charter.
