About radio

TSN 1050 (CHUM) is a commercial local sports talk radio station based in Toronto, Ontario, broadcasting on 1050 AM and owned by Bell Media. First hitting the airwaves as CHUM in 1945, it adopted the TSN brand in 2011. Today, it targets GTA listeners aged 25–54 with local English broadcasts. The main 50 kW transmitter in Mississauga covers Southern Ontario, while network shows reach sports fans right across the country.

Shows & On-Air Talent

The weekday lineup relies on fast-paced talk and big personalities. Mornings start with "First Up" hosted by Aaron Korolnek and Carlo Colaiacovo, followed by Matthew Cauz on "Game Play". Mid-afternoons belong to "OverDrive", the station's flagship drive-time show hosted by Bryan Hayes, Jeff "O-Dog" O'Neill, and Jamie McLennan. O'Neill never holds back on air, once famously warning players: "If you're playing scared in this market, Toronto will chew you up and spit you out by November.

Audio & Style

You won't find a standard song playlist here because TSN 1050 is strictly all-talk sports. Music only pops up as short bumper tracks between commercials and show openings. To keep the energy high, the station sticks to heavy rock riffs from bands like AC/DC, Foo Fighters, and The Tragically Hip.

Official Numeris PPM ratings show the station draws roughly 40,000 to 70,000 listeners daily, holding a 0.4% to 0.9% share in the 12+ demographic. People tune in for unfiltered hockey insider news, phone-in banter, and live broadcasts of games featuring the Toronto Maple Leafs, Toronto Raptors, and select MLB broadcasts.

TSN 1050 has earned solid industry respect over the years, picking up Broadcast Dialogue Canadian Radio Awards for its sports broadcasting and team members. The station's historical lineage as 1050 CHUM holds an iconic place in Canadian broadcasting history, with a legacy commemorated in the Canadian Broadcast Hall of Fame.
