On January 18, 2008,[5] a joint venture between Canwest and Goldman Sachs Capital Partners known as CW Media, [6] acquired control of BBC Kids through its purchase of Alliance Atlantis' broadcasting assets, which were placed in a trust in August 2007.

[10] The sale was completed on April 29, 2011, and with it and CRTC approval, it converted from a commercial network to a non-commercial service, while relocating operations from Toronto to Burnaby in suburban Vancouver.

The transaction resulted in a decision by cable providers in The Bahamas and Jamaica (which generally import Canadian channels onto their services for the convenience of snowbirds visiting the West Indies) to drop the network at the end of 2011.

[11][12] On October 2, 2018, a joint statement from Knowledge Network and BBC announced the channel would cease operations at the stroke of midnight on New Year's Eve 2018.

[13] Though there was no reasoning for the closure said originally, then-Knowledge chief Rudy Buttignol subsequently cited the end of the CRTC's traditional protection of small and independent networks to allow for broader discretionary services without any programming restrictions.
