CKXT-DT was a broadcast television station based in Toronto, Ontario, Canada, which broadcast to much of southern and eastern Ontario. It was owned by Quebecor Media through its Groupe TVA unit. Although beginning as a general interest independent station carrying a typical schedule of entertainment and information programming, by the time of the station's closure on November 1, 2011, the station had been converted into an over-the-air simulcast of Quebecor's cable news channel, Sun News Network. The station transmitted on channel 52 in Toronto.

Sun News Network was a Canadian English language Category C news channel owned by Québecor Média through a partnership between two of its subsidiaries, TVA Group and Sun Media Corporation. The channel was launched on April 18, 2011 in standard and high definition and shut down February 13, 2015. It operated under a Category 2 licence granted by the Canadian Radio-Television and Telecommunications Commission (CRTC) in November 2010, after the network aborted a highly publicized attempt for a Category 1 licence that would have given it mandatory access on digital cable and satellite providers across Canada.
