CHKS-FM is a Canadian radio station, which broadcasts at 106.3 FM in Sarnia, Ontario. The station broadcasts an Active rock format with the brand name K106.3. K106.3 currently competes with WHLS/WHLX in Port Huron, Michigan.
CHKS-FM can be heard in parts of Eastern Michigan, as far west as Flint, Michigan. The station conflicts with WGER of Saginaw, Michigan in Genesee and Lapeer Counties, though those with directional antennas can tune either station in these areas. The 106.3 FM signal has been heard as far south as Monroe, Michigan, however reception can be difficult due to an FM translator in Detroit that is also on 106.3FM. This tends to cause interference in southern St. Clair County, as well as in Macomb County. In Ontario, there does not seem to be as much interference. 
The station was launched in 1968 by Dancy Broadcasting, as an AM station with the callsign CKJD. The station's original AM frequency was 1250 AM. It was acquired by Rogers Communications in 1972, and moved to 1110 AM in 1977. In 1981, Rogers also launched an FM sister station, CJFI.
When Rogers acquired Maclean-Hunter in 1994, the Blue Water stations were transferred to Blackburn Radio. Blackburn converted the station to FM in 1999,  and gave the station its present call sign.
