The station originally signed on as a CBC Television affiliate on October 18, 1959, owned by Toronto architect Stanley Shenkman[1]. Shenkman also acquired the radio stationsCKSF and CKSF-FM, which both adopted the CJSS call sign as well.
In 1963, CJSS was acquired by Ernie Bushnell and converted into a rebroadcaster of Ottawa's CTV affiliate CJOH, making CJSS the first TV station in Canada ever to cease operations as its own station and become a repeater for another. After many years of use to rimshot the Montréal market, Bell Media took the station permanently dark in 2017.[1] The radio stations were sold to a local family, and subsequently broadcast as part of Corus Entertainment. Of these stations, 1220 AM (as CJUL) left the air August 18, 2010 leaving just CJSS-FM retaining the original call sign.
