As Discovery Kids (2001–2009) In December 2000, Corus Entertainment, on behalf of an organization to be incorporated, was granted approval by the
Canadian Radio-television and Telecommunications Commission (CRTC) to launch Discovery Kids, described as "a national English-language Category 2 specialty television service that offers children of all ages a fun, entertaining way to satisfy their natural curiosity with stimulating, imaginative programming that asks the questions of how? and why? and awakens the power of the mind." The channel was launched on September 3, 2001, with the
Earth Science for Children episode "All About Fossils" being the first program to air on the network. Discovery Communications purchased a minority stake in the service either prior to or shortly after the channel's launch.
As Nickelodeon (2009–2025) In September 2008, Corus Entertainment was given approval by the
Canadian Radio-television and Telecommunications Commission (CRTC) to launch a specialty channel named "YTV OneWorld", described as featuring "programming from around the world targeting children and teenagers aged 6 to 17 and their families. The schedule would include programs devoted to entertainment, humour, travel, games and science and technology." In September 2009, Corus announced it had reached an agreement with
MTV Networks, a subsidiary of
Viacom, to launch Nickelodeon in Canada as a domestic channel. The channel was relaunched as "Nickelodeon" on November 2, 2009, at 6 a.m. using the "YTV OneWorld" license.
Jacob Two-Two was the first show broadcast under the Nickelodeon name, shortly after Discovery Kids' final broadcast of
Aquateam. Because it was legally a distinct service, subscription television companies had to reach new agreements with Corus in order to carry Nickelodeon, as Discovery Kids operated under a different license. Earlier in April, Discovery announced that it would relaunch the American version of Discovery Kids in a joint venture with
Hasbro, which would be known as the Hub Network before being rebranded as
Discovery Family in 2014. On April 9, 2013, Telus Optik TV launched Nickelodeon HD, a high-definition simulcast of the standard-definition feed. It was later launched on June 25, 2013, for
Rogers Cable and added to Bell Fibe TV's service on October 25, 2013. On September 22, 2015, Corus Entertainment announced the launch of Nickelodeon GO, an app that allowed viewers to watch the channel live, as well as stream shows from its American counterpart. The app was available for
iOS and
Android platforms,
but required a subscription to Nickelodeon from a pay TV provider. In June 2019, as part of the launch of
Amazon Prime Video Channels in Canada, Corus launched a standalone subscription
video on demand channel featuring Nickelodeon content, later branded as
Nick+.
Closure On July 10, 2025, Corus announced that it would close Nickelodeon along with four of its
Disney Branded Television-affiliated specialty channels (
Disney Jr.,
Disney XD,
La Chaîne Disney, and
ABC Spark) on September 1. On August 18, Corus announced that they would no longer distribute Nickelodeon programming on both YTV and Treehouse, and that all Nickelodeon programming would be removed from both channels permanently on the same day the Nickelodeon channel shut down. Nickelodeon closed in Canada permanently at midnight on September 1, 2025, with the final show to air on the channel being the
Zoo Diaries episode "Monkeys in Trouble", after which the channel switched to a
slate stating "This channel is no longer available". A number of Nickelodeon programming formerly aired on this channel along with YTV and Treehouse all remain available in Canada through the
Paramount+ streaming service. ==Programming==
