Owned and operated by network parent Corus Entertainment, the station has studios on Robin Crescent on the northwest side of Saskatoon (near the Saskatoon John G. Diefenbaker International Airport), and its transmitter is located on Agra and Settlers Ridge Roads (near Highway 41), northeast of the city.

CFSK and its sister station in Regina, CFRE-TV, were initially branded as "STV" (short for "Saskatchewan Television").

At the time that STV went on the air, it was Saskatoon's third locally based over-the-air television station, joining a market that included CTV's CFQC and the then-operational CBC affiliate, CBKST.

On August 20, 2012, CFSK expanded its half-hour 10 p.m. newscast to one hour, which was retitled from Prime News to News Hour Final; the addition of the morning newscast and the expansion of the prime time newscast is part of an expansion of local news programming on Global owned-and-operated stations across Canada as part of a benefits package that was included as a condition of the sale of the Global Television Network to Shaw Communications.

On August 15, 2011, 2+1⁄2 weeks before Canadian television stations in CRTC-designated mandatory markets were slated to transition from analogue to digital broadcasts, CFSK flash cut its digital signal into operation on UHF channel 42, using virtual channel 4.
