The station was launched in 1984 by Gateway City Broadcasting, at 1110 AM. It was subsequently acquired in 1985 by Mid-Canada Radio, who also changed the station's frequency to 840 AM. In 1990, the station was acquired by the Pelmorex Radio Network.
In July 2010, the station altered its musical format to present a more contemporary version of its AC Mainstream Plus blend more in line with the Hot AC version of American Top 40 with Ryan Seacrest. With this shift, the station cancelled The 80's Lunch program and Sunday at the 70's. Solid Gold Saturday Night was replaced by American Top 40 (which now airs at 9 AM Saturday mornings). In July 2011 the station also adopted a new logo as well as the positioning statement 'Today's Best Music.'
By January 2012, more hot adult contemporary and rhythmic contemporary hits were added to the playlist. The station also unveiled the HitStorm countdown, based out of Toronto's CKIS-FM. In March 2012 all of the Rogers-owned EZ Rock stations in Northern Ontario started to air the Top 20 Most Wanted, a countdown show produced by CJMX-FM in Sudbury. By June 2012, the station dropped the entire 1980s library and most pre-2000 music from its playlist, making it one of the few AC stations to not follow the adult contemporary pattern.
CHUR was one of four EZ Rock-branded stations owned and operated by Rogers Media, all of which are located in Northern Ontario (the others are located in Sudbury, Sault Ste. Marie, and Timmins); as of July 2013, Rogers is in the process of rebranding all 4 stations, and is entertaining listener input through surveys on the stations' websites and through social media. On August 29, 2013, all EZ Rock stations rebranded to "Kiss", discarding the EZ Rock branding now owned by Bell Media Radio.
