About This Station

CHOK 1070 & 103.9 is a commercial radio station serving the Sarnia, Ontario, and Port Huron, Michigan, cross-border region. While its website offers little detail beyond the "BIG Country 103.9" branding, that name strongly suggests a country music format, though directory tags also list adult contemporary. The station's tags and heritage callsign indicate a broader focus on news, sport, and local information alongside its music programming. It is owned by Blackburn Media Inc., as noted in the site's copyright line. Overall, it appears to be a locally focused, music-led station with a strong community information component.
