The station is owned by the Canadian Broadcasting Corporation (known in French as Société Radio-Canada).

As a privately owned station, CKSH basically functioned as a semi-satellite of CBFT (channel 2) in Montreal due to not having alternative non-network sources of programming available.

After several years, CKSH began airing its own local news and a few programs not carried by CBFT.

CKSH and TVA owned-and-operated station CHLT-DT (channel 7) in Sherbrooke are seen on some cable systems in Northern New England, serving the French American community.

An application to directly acquire the station was filed by Radio-Canada on April 25, 2008, concurrently with Cogeco's proposed sale of TQS to Remstar Corporation.
