Its studios are on West 8th Avenue in the Fairview neighbourhood of Vancouver, while its transmitter is located atop Mount Seymour.
CJOR increased its transmission power to 1,000 watts in 1941, moving its transmitter site to Lulu Island.
(After the station switched to FM in 2008, CISL moved to the Lulu Island location, making it the oldest broadcasting site in the Vancouver radio market in continuous operation.)
The Board of Broadcast Governors (predecessor of the Canadian Radio-television and Telecommunications Commission, or CRTC) had decided not to allow the station parent CJOR Ltd. to renew the license.
By the 1970s, the station shifted its focus away from music to talk radio, with such colourful and opinionated personalities as Jack Webster, Pat Burns, and eventually, former British Columbia premier Dave Barrett.
On September 2, 1988, at noon, CJOR dropped its talk radio format, flipping to classic rock under new call letters CHRX.
On January 7, 1994, at 6 p.m., after signing off with Led Zeppelin's "Stairway to Heaven", the station began stunting with the sound of ocean waves.
On January 9, at noon, it switched formats and call signs again, becoming CKBD with the on-air brand The Bridge as Canada's first Contemporary Christian music station.
[11] Astral Media's CISL had flipped from oldies to adult standards just days before to take advantage of the move.
"[12] CKPK-FM received a new competitor on Canada Day, 2009, when CHHR-FM began airing a AAA format.
On December 9, 2010, the Jim Pattison Group applied to exchange frequencies with non-commercial community radio station CFRO-FM, which then operated at 102.7 MHz.
[19] In January 2023, CKPK laid off The Peak's on-air personalities; the company cited low adoption of HD Radio by local listeners as its reasoning for the cutbacks.
Program director Russell James credited the "impressively dedicated" audience that CKPK's Peak digital stream retained as an impetus for the decision.
