The station says it plans to celebrate Denis’s career in the months leading up to her final broadcast, with more details, including her last show date, to be announced.
“It’s no secret that I love radio. Working in the iconic CHUM universe for 40 years has been an absolute privilege,” Denis said.
“As I make the decision to step away from the station I love, I look back with pride and gratitude, knowing I had the honour of saying, ‘I worked at CHUM’. And now, the real adventure is ahead – and I’m looking forward to all of it.”

Born in Edmonton, Denis began her career as the first female DJ at KRPL in Moscow, Idaho, before moving to Calgary for various radio and television roles.
