1050 CHUM (50,000 watts) played Top 40 Hits from the 1950’s to the 1980’s, then switched to an oldies format with music from 1989 to 2009. Next came a sports format, and in 2011 it became TSN Radio 1050, and now the format has switched to news, and the station is known as CP24 Radio 1050.
CHUM-FM at 104.5 began broadcasting on September 1, 1963. It was the first private TORONTO station to play classical music all day long. On July 1st, 1968 it switched to progressive rock. Until 2009 it was the most listened-to and influential radio station in Canada. Now, with its transmitter on top of the CN Tower, CHUM-FM features an adult contemporary format. It’s still one of TORONTO’s most popular radio stations.
