Indeed, one of the changes the bill proposes is making sure the CRTC does have information-gathering powers so that it could go to a service operating in whole or in part in Canada and ask for certain information from them, such as their Canadian revenues.
I had understood Mr. Julian's question to be what happens if that company basically refuses to play ball, so to speak, with the CRTC, claiming they weren't subject to its jurisdiction. That was how I understood Mr. Julian's question.
However, you are right. Yes, the CRTC does have those powers to ask for this kind of information.
