In mid-June 2013, after CING-FM switched formats from Classic Hits to hot AC, CKOC added more 1970s' and 1980s' music to its playlist. It was the first time since February 1992, when the station changed its format, that any music later than the 1970s has been played on the station, a trend mirroring most other oldies outlets in North America, which have moved away from the oldies positioning and have adopted classic hits approaches. The station dropped the "Great Oldies" reference and referred to itself as "Classic Hits 1150 CKOC".
