  • Marilyn Denis Marilyn Denis Sure, Marilyn Denis is an award-winning, iconic and influential figure in Canadian broadcasting. But to us, she's simply one of the funniest, wittiest and friendliest people at CHUM 104.5. She's a superstar with a self-deprecating sense of humour; a proud mom and an avid Pittsburgh Steelers fan and is the host of "The Marilyn Denis Show" on CTV.
  • Jamar Jamar Jamar's been a radio host for some of the biggest radio stations in the United States and in the Caribbean. Besides doing shows on the radio he is also a TV actor, an accomplished club/party DJ and music producer known as J Niice specializing in Pop, Dancehall, Reggae and Soca.
  • Caitlin Green Caitlin Green Has been known to smile & talk to dogs before their owners. Lifelong gangster rap enthusiast. Is made up of 50% cheeseburgers, 50% sarcasm. REALLY good at writing her own bio.
  • Tom Jokic Tom Jokic Tom Jokic is the producer of Marilyn Denis and Jamar. Tom’s a font of useless knowledge, which he shares with Marilyn and Jamar., whether they want to hear it or not! Tom’s a graduate of Loyalist College and is the father of two sons, who only occasionally roll their eyes at their dad’s sense of “humour”.
  • Richie Favalaro Richie Favalaro Richie Favalaro kicks off your Workday through to 2pm!
  • Ashley Greco Ashley Greco Having listened to CHUM FM as a kid, it’s kind of a dream come true that Ashley now has her own show on the station. She tends to pinch herself from time to time. To describe her as a radio junkie would be an understatement. She eats, sleeps and breathes it. Her start in the biz was over 10 years ago as a traffic reporter. Since then, she’s spent six years on morning radio in Toronto and now you can hear her 2-7pm on CHUM FM.
  • Meredith Shaw Meredith Shaw Born and raised in Toronto, Meredith has a true passion for music. As singer and songwriter herself she brings an artist's perspective to radio. She is honest, curious and always ready for a good giggle. If you introduce her to Ryan Gosling while serving her bread pudding she might explode
  • Taylor Kaye Taylor Kaye Taylor Kaye takes you through the weekend with 40 mins of non-stop and commercial free music every hour.
