CHEX-DT

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.

For decades, cable systems in Peterborough have carried CBC flagship CBLT in Toronto alongside CHEX. Due to this unique situation, CHEX-TV was frequently used during Hockey Night in Canada to air alternate games. During the 1970s and 1980s, CHEX would often air games from the Montreal Canadiens over the geographically closer Toronto Maple Leafs. During the 2000s and early 2010s, CHEX was also used by the CBC as an overflow channel for its regional coverage of the Stanley Cup Playoffs—in the event of scheduling conflicts between games in series which CBC held rights to, the game of greater national interest would be carried across the network, while the other game would be carried exclusively by CHEX, and simulcast on the CBC Sports website. This practice ended following the 2014 Stanley Cup Playoffs, as the CBC's rights are now sub-licensed from Rogers Communications and any conflicting games are reassigned to other Rogers-owned channels.

Previous logo used from 2013 to 2016. An earlier variant of the logo featured cyan and green bars instead of red.

CHEX used to operate two rebroadcast transmitters on VHF channels 2 and 10, in Bancroft and Minden, respectively. The Bancroft transmitter, still on the air today, switched to Channel 4 before Global station CKGN-TV established a transmitter there on Channel 2 in 1974. The Minden transmitter switched to Channel 7 at some point, and shut down in the early or mid-1980s. In 1992, CHEX-TV-2 in Oshawa signed on as a semi-satellite of CHEX. That transmitter was added in order to overcome an impaired signal for Channel 12 in that area. CHEX long claimed Oshawa and the Durham Region as part of its primary coverage area, even though it is part of the Greater Toronto Area. The Oshawa station began airing a partially-separate schedule, including a separate newscast, in 1993, and by 2004 had completely broken off from CHEX to become a separately-programmed station with its own facilities and staff (though retaining a rebroadcaster-like callsign).

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.[2][4][5] 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.[6] CTV also serves the market through a local rebroadcaster of the network's Toronto owned-and-operated station (O&O) CFTO-DT.

Former logo used from October 2016 to August 2018.

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.[7] The switch was approved by the Canadian Radio-television and Telecommunications Commission (CRTC) on August 27, 2015, when it dismissed 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 as he only received television over the air, he would lose his ability to receive CBC Television as a result of the disaffiliation.[8] 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 the station's newscasts.[9]

Local newscasts, branded as CHEX News, air weekdays from 6-9 a.m., at 12:00 p.m., weeknights at 5:00, 5:30, 6:00 & 11:00 p.m., and weekends at 6:00 p.m.. On October 24, 2016, CHEX premiered a morning newscast known as The Morning Show (now known as Global News Morning. On September 6, 2016, the station began carrying Global National.[10][11] The following day, CHEX moved its late night newscast to 11:00 pm, replacing CTV National News. The vacant timeslot at 11:30 pm was replaced by ET Canada.[12] As a result, CHEX did not carry any of CTV's news shows during its 3-year link with the network, including the aforementioned National News and the national morning show Your Morning, as both shows can be seen on a Peterborough transmitter of Toronto's flagship station CFTO-DT, CTV News Channel, and on both the CTV and CTV News websites.

As of September 2011, CHEX-TV had not yet begun broadcasting in digital. The CRTC has not listed Peterborough as one of its mandatory markets for analogue television shutdown and digital conversion,[13] and therefore CHEX-TV was not required to convert to digital transmissions on the transition date of August 31, 2011.[14]

CHEX-TV began offering a high definition feed on Cogeco Cable in the Peterborough area in November 2010. Over-the-air digital broadcasts were tentatively planned to commence on May 9, 2013, but the station was delayed a few days in converting to digital operations.[15] CHEX's high definition signal is not currently available via either Bell TV or Shaw Direct.[16]

CHEX made the switch from analog to digital on May 9, 2013.[17]
