CFAJ (1220 kHz) is a AM radio station in St. Catharines, Ontario, Canada. It broadcasts a Classic Hits radio format..
CFAJ broadcasts at 10,000 watts using a directional antenna with a nine-tower array to prevent co-channel interference with WHKW Cleveland, as well as 1230 WECK in Cheektowaga, forty miles to the east. CFAJ can be heard as far north as parts of cottage country and west beyond Guelph. The transmitter is off Turner Road in Thorold, near the Welland Canal.
In 1967 the station signed on the air as CHSC. It was owned by Radio Station CHSC Ltd., which also launched CHSC-FM at the same time. The station was acquired by Coultis Broadcasting in 1990. CHSC had a full service adult contemporary radio format, with some oldies attracting audiences ages 30 and up, both male and female. CHSC played a mix of 50 per cent gold and 50 per cent current/recurrent of which 45 per cent on average consisted of Canadian content during the broadcast week of Sunday to Saturday.
After several years of construction and planning, 1220 returned to the air in 2020 with the new call sign CFAJ.
