CP24 (of all places) has got this tidbit: Corus is down Teletoon Retro at the end of August. (Here’s the link)
Some programming could shift to Teletoon proper, and I can assume we’ll be getting further announcements as the channels realign themselves. The broadcast landscape is shifting almost weekly it seems, with DHX dropping their Disney licenses, and Corus picking it up. Cogeco recently announced that Bite TV is shutting down as well. It’s getting increasingly tough to keep track of who’s in the cartoon business, it seems.
