CHEX-DT, VHF analogue and digital channel 12, is a CTV-affiliated television station located in Peterborough, Ontario, Canada. It is owned by Corus Entertainment. CHEX maintains studio facilities located on Monaghan Road (near Rose Avenue) in the southern portion of Peterborough, and its transmitter is located on Television Hill, just outside Peterborough.
CHEX is available on Cogeco Cable channel 2 in standard definition and digital channel 902 in high definition; Shaw Direct channel 48 on the advanced tier and channel 348 on the classic tier; and Bell TV channel 217.
CHEX began airing CTV programming on August 31, 2015 under a programming supply agreement, terminating its relationship with the CBC after 60 years.
The station signed on the air on March 26, 1955 as an independently-owned affiliate of CBC Television; its inaugural broadcast was an National Hockey League ice hockey game. CHEX was founded by a media partnership that already published the Peterborough Examiner newspaper and owned radio station CHEX (now CKRU). The partnership included politician Rupert Davies, who was also involved in a similar arrangement in Kingston that established CKWS-TV. The Davies family sold its media interests to Power Corporation of Canada in 1976. On April 13, 2000, the station was acquired by Canadian media conglomerate Corus Entertainment.
CHEX-TV-2, UHF analogue channel 22, is a low-powered CTV-affiliated television station serving the Regional Municipality of Durham that is licensed to Oshawa, Ontario, Canada. The station is owned by Corus Entertainment. CHEX-TV-2 maintains studio facilities located on Simcoe Street (just north of King Street) in Downtown Oshawa, and its transmitter is located on Enfield Road in Clarington. Known on-air as "Channel 12 Durham", the branding is derived from CHEX-TV-2's primary cable position in Oshawa on Rogers Cable; the station is also available on Rogers Cable digital channel 129 in the Greater Toronto Area.
Although operating as a separate station from Peterborough sister station CHEX-DT, it retains the CHEX-TV-2 callsign used when the station operated as a rebroadcaster of CHEX.
CHEX-TV-2 ended its affiliation with CBC Television on August 31, 2015, when it became an affiliate of CTV.
Oshawa, although larger in population density than Peterborough, had not been granted a television station in the original channel assignments issued during the 1950s. Instead, the city was folded into the Toronto market. CHEX-TV-2 signed on the air in 1992, when CBC Television affiliate CHEX-TV in Peterborough began relaying its programming on a new rebroadcast transmitter in Oshawa; prior to 1988, the UHF channel 22 allocation had been used by a Toronto area rebroadcaster of CIII-TV.
