CBKST was the CBC Television owned-and-operated television station in Saskatoon, Saskatchewan, Canada from 1971 to 2012. Broadcasting an analogue signal on VHF channel 11 from a transmitter located between Highways 5 and 41, it was a semi-satellite of CBKT-DT in Regina and aired separate commercials.
Owned by the Canadian Broadcasting Corporation, its master control facilities were located in the Hutchinson Building on 2nd Avenue South (between 21 and 22 Streets East) in Downtown Saskatoon. This station could also be seen locally on Shaw Cable channel 12 and Sasktel Max channel 3.
CBKST was licensed as a rebroadcaster of CBKRT, even though it operated as a semi-satellite with its own associated network of repeaters. While the CBC originally planned to discontinue CBKST's over the air feed on August 31, 2011 (as the corporation did not originally plan to convert rebroadcasters in mandatory transition markets like Saskatoon to digital), the CRTC granted the CBC permission to allow transmitters in selected mandatory markets, including Saskatoon, to still operate an analogue feed until August 31, 2012. On July 17, 2012, the Canadian Radio-television and Telecommunications Commission (CRTC) approved CBC's application to delete CBKST from CBKT's licence, effective August 1, 2012. On July 31, 2012, CBKST was shut down after more than 41 years on the air.
Since the closure of CBKST, cable and satellite providers have piped in CBKT (which took over CBKST's slots) and other CBC outlets for their customers. Due to the high penetration of cable and satellite in central and northern Saskatchewan--a must for acceptable television in much of the province--few viewers actually lost access to CBC programming.
