CJSS-FM

CJSS-FM is a Canadian radio station, which broadcasts at 101.9 FM in Cornwall, Ontario. The station broadcasts a classic hits (70s, 80s & 90s) format branded as Boom 101.9.

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.

By 1963, Shenkman had sold his broadcast holdings. Ernie Bushnell purchased CJSS-TV 8, using it as a repeater of Ottawa's CJOH-TV; the radio stations were sold to the local Émard family.

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).
