The station broadcast with a power of 10,000 watts from its transmitter site located on Scotland Drive in South London.

During the Oldies 1410 years, the station also broadcast various religious and ethnic programs in evenings, including Radio Maryja from Poland seven days a week from 8-9 p.m. Due in part to the location of its transmitter site in South London, CKSL has been dogged by low listenership.

[6] On July 11, 2016, Bell Media applied to the CRTC for a request to terminate CKSL's broadcast license, citing severe deteriorating conditions at the transmitter site.

A technical review was done at the location of CKSL's transmitter building and towers by Bell Media and its contractors, and they found that the AM array's broadcast towers posed a structural risk, as well as needing their aircraft warning lights to be repaired to bring it back up to proper building, safety and aircraft codes.

The cost estimate to repair all these issues was in the $CAD 3 million range, and with CKSL's long-term ratings performance at dead last of the ten commercial radio stations serving the London area, and with little hope of that changing any time soon, coupled with the region's four per cent decline of advertising revenue in radio since 2013, the CRTC accepted Bell's request to shut down CKSL.
