> I can only think of Rush, Bieber, and Kids in the Hall.

Don't forget Avril Lavigne, Drake, Gordon Lightfoot, Céline Dion, Joni Mitchell, deadmau5, The Weeknd, and Nelly Furtado.

Just off the top of my head. Interestingly enough I'd never heard of Kids in the Hall before today. But all of those are or were "Big Names" in music.

We have (protectionist, yes) media regulators (the CRTC) that are nominally arm's length from elected governments so it's not likely to change unless the Canadian public decides that this will become a major election issue. Don't hold your breath.
