Channel 79 was removed from television use in 1983, but was formerly used by several television stations in North America which broadcast on UHF frequencies covering 860-866 MHz:
- CITY-TV in Toronto, Ontario first broadcast on this frequency in 1972, the highest frequency of any North American terrestrial originating station. Initially a 31 kW signal, it upgraded in 1976 to 208 kilowatts from the CN Tower. The station has been repeatedly displaced by cellular telephone encroachment on what were formerly broadcast frequencies. On July 1, 1983 the station was moved to channel 57; in August 2011 it moved to digital UHF channel 44 and in 2020 it was repacked to physical UHF 18, but it retains "57.1" as its over-the-air virtual channel.
