The station was launched in 1945 by the city's daily newspaper, the Cornwall Standard Freeholder, with the call sign CKSF. In 1957, the newspaper also launched CKSF-FM. Two years later, the stations were acquired by Stanley Shankman, the owner of CJSS-TV, and both changed their callsigns to CJSS as well.
The radio stations were subsequently acquired by Tri Co Broadcasting in 1978. Tri Co converted CJSS to the FM band in 1999. CJSS' former frequency, 1220 AM, did not go dark, but changed to an adult standards format as CJUL (The Jewel).
On August 18, 2010, CJUL (AM 1220) left the air. Corus stated that more listeners across Stormont, Dundas and Glengarry would now get up-to-date local and regional information on local radio as Corus Radio redeployed news and community event information from AM 1220 (CJUL) onto its two FM stations, Variety 104.5 (CFLG-FM) and Greatest Hits 101.9 (CJSS-FM). 
On February 15, 2011, CJSS-FM changed its format to classic hits, branded as "Greatest Hits 101.9 FM".
On August 25th, 2014, at 3PM, CJSS-FM rebranded as Boom 101.9. The last song on Greatest Hits 101.9 was Revolution by The Beatles, while the first song on Boom 101.9 was Don't Stop Believin' by Journey.
