CIII-DT (channel 41) is a television station in Toronto, Ontario, Canada, serving as the flagship station of the Global Television Network. Owned and operated by network parent Corus Entertainment, CIII-DT maintains studios at 81 Barber Greene Road (near Leslie Street) in the Don Mills district of Toronto, and its transmitter is located atop the CN Tower in downtown Toronto. The station reaches much of the population of Ontario through a network of 12 transmitters across primarily the southern and central portions of the province (as a result, it is the de facto Global outlet for the capital city of Ottawa through repeater CIII-DT-6). Since August 29, 2022, CIII-DT serves as the master control hub for all 15 Global owned-and-operated stations across Canada. History Ken Soble, the founder of CHCH-TV in Hamilton, envisioned a national "superstation" of 96 satellite-fed transmitters with CHCH as its flagship. In 1966, he filed the first application with the Board of Broadcast Governors for a network to be branded as NTV — however, the application faced various regulatory hurdles and underwent numerous revisions over the next number of years. The Canadian Radio-television and Telecommunications Commission (CRTC) eventually decided to go ahead with the publicly owned Anik satellite system instead of relying on private communications companies to build Canada's satellite broadcasting infrastructure, placing the NTV application in jeopardy after Power Corporation of Canada, a key investor in the plan, backed out. In 1970, one of Soble's former employees, Al Bruner, teamed up with Peter Hill to revive the application under new ownership. Bruner and Hill's group, Global Communications, scaled back the original NTV proposal to a network of seven UHF transmitters in Southern Ontario, whose combined footprint would have provided at least secondary broadcast coverage from Montreal to Detroit. Global Communications still aspired to eventually build out Soble's original 97-station network, and viewed the seven-transmitter Ontario chain as an interim step. However, since CHCH was no longer involved in the application, Global's iteration of the plan also required the launch of a new station to serve as its flagship. The station first signed on the air on January 6, 1974 as CKGN-TV (before its use by the station, the CKGN callsign had previously been used by what is now CTV owned-and-operated station CKNY-TV in North Bay from 1955 to 1962). It branded itself as the "Global Television Network," a name which reflected its then-unprecedented coverage of most
