[1] Teletoon Retro was shut down on September 1, 2015, and either replaced by Cartoon Network or Disney Channel, with the former inheriting the service's CRTC license and some of its carriage agreements.

[3] The channel was launched at 6:00 PM EST on October 1, 2007, across all major television providers with its first program being The Bugs Bunny and Tweety Show.

[5] On February 4, 2013, the channel underwent a refresh with new graphics and bumpers created by John Lee, retiring the "television sets" era from 2009 to 2013.

[citation needed] Shaw Direct, SaskTel, Bell MTS, and Telus Optik TV never launched the feed in time.

[15] The transition was legally structured so that Cartoon Network would cease to exist as a separately-licensed service as of September 1, 2015, and henceforth operate under Teletoon Retro's category B license instead.

[16][17] Cartoon Network was ultimately relaunched as a Canadian version of Boomerang on March 27, 2023,[18] thus returning a classic animation format to the former Teletoon Retro channel space.
