CHUM, branded as TSN Radio 1050, broadcasting at 1050 kHz in the AM band, is a Canadian radio station licensed to Toronto, Ontario. The station is owned and operated by Bell Media.
Long known as 1050 CHUM, the station played Top 40 hits from the late 1950s to early 1980s. CHUM then carried an oldies format featuring music from that period between 1989 to 2009, except for a brief stint as a sports radio station, The Team 1050, from 2001-2002.
In March 2009, CHUM switched to an all-news format known as CP24 Radio 1050, which operated primarily as an audio simulcast of CP24.
In April 2011, CHUM reverted to a sports format as TSN Radio 1050.
