[5] In 1951, Florence Buchanan assumed full control of Telephone City Broadcast Limited, including CKPC-FM and CKPC, from her father Cyrus.

In 1972, Florence's son Richard Buchanan assumed control of Telephone City Broadcast Ltd.[1] CKPC was an affiliate of CBC Radio's Dominion Network until 1962 when the station became an independent outlet.

In 1980, during a live appearance on a CKPC talk show, Prime Minister Joe Clark revealed that the Canadian government had assisted in the rescue of six American diplomats during the Iran hostage crisis.

[6][2] On March 15, 1999, Telephone City Broadcast Ltd. was denied an application to add an FM translator at Simcoe to operate on 98.9 MHz with an effective radiated power of 1,090 watts.

The proposed rebroadcasting transmitter was intended to correct coverage inadequacies in CKPC's AM signal to the Simcoe, Port Dover and Delhi area.

[10] Telephone City Broadcast was held by Buchanan's estate until July 2009, when an agreement was reached to sell the stations to Evanov Communications, pending CRTC approval.

In February 2020, the CRTC approved a request by Evanov to move sister station CFWC-FM's Christian format to CKPC.
