O 92.1 — CJDM-FM

O 92.1 Drummondville (CJDM-FM) is a French-language commercial radio station based in Drummondville, Quebec, broadcasting at 92.1 FM. The station began operations on August 15, 1988. Its call letters—“CJDM”—combine the national prefix “CJ” with “DM,” representing Drummondville. Over the years, it underwent multiple ownership shifts, including transitions from Corus Entertainment to Astral Media and eventually Bell Media. During that period, it became part of the Énergie network, known for its mainstream rock programming. In February 2024, Bell Media announced the sale of CJDM-FM to Arsenal Media, a deal approved by the CRTC in March 2025. The station was officially relaunched as O 92.1 Drummondville on April 22, 2025, joining the O network.

With refreshed branding and new direction, the station brings dynamic content tailored to today’s listeners in Drummondville and surrounding areas.
