Development of a separate channel started when YTV aired preschool shows as part of its weekday morning line-up.

[9] In early 1996, it was announced that YTV was looking to "break part of [its] audience off with a separate network aimed at viewers under the age of 6.

"[10] The network's president, Patricia Macdonald, said she had "done a lot of research that led us to the conclusion that the kids market is underserved.

"[11] On September 4, 1996, the Canadian Radio-television and Telecommunications Commission (CRTC) approved YTV's request to launch a new channel called Treehouse TV.

Between June 2015 and May 2019, Corus operated TreehouseGO, a TV Everywhere service available on iOS and Android devices.

[18] On February 5, 2013, Nelvana, Corus Entertainment's animation division, launched the Treehouse Direct channel on YouTube.

[20] On July 19, 2019, Corus Entertainment filed a copyright infringement lawsuit against a medical marijuana dispensary chain, known as "Treehouse Dispensary", alleging the chain "wilfully copied and is using a confusing similar imitation" of the Treehouse TV logo.

An attorney for the dispensary contested the claims and said that the business "categorically denies that its logo infringes on any existing trademarks in the United States.
