If you haven't watched Tuesday's Son Of A Critch on CBC, this doesn't require a spoiler, because it has almost nothing to with the plot. But it was a weird meta moment, with a giant mistake in it. 

Famed Canadian comedian Rick Mercer plays the owner of VOCM, St. John's, Newfoundland. In a scene from the show, he's telling Mike Critch (played by Mark Critch) about the other stations he controls. Most of them are legit. 

He mentions CKCM (which is a real station in Grand Falls-Windsor, Nfld.), CHCM (Marystown, Nfld.) and CHVO, which is noted as bring a rebroadcaster of VOCM, which in fact, it is. It's located in Carbonear, Nfld. (All are actually owned by Stingray.)

But the mistake comes when Mercer mentions one last set of call letters - CKCO. That, of course, is the Bell-owned CTV TV station in Kitchener. As far as I know, it was never assigned to any radio station, and certainly not an AM outlet in Newfoundland. After apparently doing their homework, I can't help but wonder how they blew that last one - unless somehow it was a deliberate homage to the local TV outlet.
