CBYT was the call sign for the CBC's television transmitter in Corner Brook, Newfoundland and Labrador, Canada, broadcasting on channel 5. It was carried on cable channel 4 in Corner Brook. CBYT launched as a full-fledged station on June 17, 1959 rebroadcasting the signal from CBHT in Halifax, Nova Scotia until CBNT in St. John's launched in 1964. It was once a semi-satellite of CBNT, carrying a partially separate newscast and producing some programs of its own. However, at its closure, the station was a full rebroadcaster of CBNT, even carrying CBNT's commercials.
