CHEX-DT (channel 12) is a television station in Peterborough, Ontario, Canada, part of the Global Television Network. Owned and operated by network parent Corus Entertainment, the station maintains studios on Monaghan Road (near Rose Avenue) in the southern portion of Peterborough, and its transmitter is located on Television Hill, just outside the city. History The station signed on the air on March 26, 1955, as an independently-owned affiliate of CBC Television; its inaugural broadcast was a 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. On May 20, 2015, Corus and Bell Media announced an agreement whereby its three CBC stations would leave the public network (after 60 years in the case of CHEX) and "affiliate" with CTV. The affiliation switch took effect on August 31, 2015. Most TV service providers serving the region already carry CBLT, and any that do not will have to add a CBC affiliate such as CBLT to their basic services in order to comply with Canadian Radio-television and Telecommunications Commission (CRTC) regulations. Legally the affiliation with CTV was described as a "program supply agreement", and not as an "affiliation" (a term with specific legal implications under CRTC rules), as Corus maintained editorial control over the stations' programming and the ability to sell local advertising, and did not delegate responsibility for CTV programs aired by the station to Bell Media. The switch was approved by the CRTC on August 27, 2015, dismissing objections by Rogers Media (who argued that the change was an "affiliation" and thus required CRTC consent to implement, and was not in the public interest because it created duplicate sources of CTV programming), and by a resident who complained that because he only received television over the air, he would lose his ability to receive CBC Television as a result of the disaffiliation. Following the expiration of CHEX's three-year deal with CTV, the station became a Global owned-and-operated station (O&O) and rebranded itself as Global Peterborough on August 27, 2018; the CHEX branding will be retained for
