Owned by Evanov Communications, it broadcasts a classic hits radio format focusing on pop, rhythmic, and rock music from the 1980s, 1990s, and 2000s.
The station was branded as Cafe 100.7 and adopted an adult album alternative (AAA) format on December 26 of that year with the call sign CKFE-FM.
In September 2007, CHNK successfully applied to the Canadian Radio-television and Telecommunications Commission (CRTC) for a power increase, citing reception difficulties in the market.
[4] On July 6, 2010, the station became K-Rock 100.7 and switched to a blues-leaning classic rock format, retaining its CHNK call sign.
[11] In August 2014, the CRTC approved a request by Evanov to move CFJL to the frequency of 100.5 FM, and increase its power to 100,000 watts.
Evanov felt that the 100.7 frequency had attracted a poor stigma among advertisers and listeners due to the station's failed attempts to "generate audience interest" under specialty formats.
