CKXT-DT

CKXT-DT was a broadcast television station based in Toronto, Ontario, Canada and serving much of southern and eastern Ontario, owned by Quebecor Media through its Groupe TVA unit. At the time of the station's closure on November 1, 2011, the station was serving as an over-the-air simulcast of Quebecor's cable news channel, Sun News Network (Sun News). The station transmitted on channel 52 in Toronto.

CKXT began broadcasting on September 19, 2003 as a general-interest independent station branded Toronto 1 and was owned by Craig Media. Following the station's sale to Quebecor, it was rebranded as SUN TV on August 29, 2005. It then began to simulcast Sun News upon that channel's launch on April 18, 2011.

Although Sun News was licensed as a Category C (optional carriage) digital specialty channel, CKXT, as a broadcast station, had mandatory cable carriage in its over-the-air service area. Hence the simulcast meant that Sun News programming was available to analog cable subscribers throughout southern and eastern Ontario. However, the station retained its own broadcast license separate from the specialty channel. The station's Ottawa transmitter was closed on August 31, 2011, while the remaining transmitters in Toronto, Hamilton, and London were closed on November 1, 2011.
