Teletoon Retro was a Canadian specialty channel that was owned by Corus Entertainment that was based on the Teletoon programming block. The service was dedicated to broadcasting classic animated television programs as well as some live-action series. Along with its French-language sister channel Télétoon Rétro, it was available in over nine million Canadian households as of 2013; together it had the most subscribers among the digital Canadian specialty channels. Teletoon Retro was shut down on September 1, 2015, with Cartoon Network inheriting the service's CRTC license and some of its carriage agreements. That channel would later relaunch under Cartoon Network's own classic animation brand Boomerang in 2023.
