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.

"[1] 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.

On the day of the channel's launch, Discovery Kids (which Corus also owned) was shut down and replaced by Nickelodeon on most pay-TV providers after the last episode of Aquateam ended.

[3] Because it is 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.
