[1] The station was in operation from 1971 to 2002 as a private affiliate of CBC Television, and then continued until 2012 as a network-owned rebroadcaster of CBLT in Toronto.

That transmitter was sold to the CBC in 1982, although it continued to air CKNC's signal for the remainder of the station's existence.

Until 1980, CICI and CKNC aggressively competed with each other for advertising dollars, leaving both in a precarious financial position due to the Sudbury market's relatively small size.

[5] CTV subsequently sold its four CBC affiliates in Northern Ontario, CKNC, CHNB in North Bay, CJIC in Sault Ste.

[6] All four ceased to exist as separate stations on October 27, 2002, becoming rebroadcasters of Toronto's CBLT, with CKNC's call sign changing to CBLT-6.
