O 104.1

O 104.1 (CFZZ-FM) is a French-language radio station broadcasting from Saint-Jean-sur-Richelieu, Quebec, on 104.1 FM. The station traces its roots back to 1956, when it signed on as CHRS on 1090 AM. In 1992, it made the move to the FM band and adopted its current call sign. It became part of the Boom FM network in 2005 and was later acquired by Bell Media in 2012 following the purchase of Astral. On May 21, 2018, it shifted to a modern adult contemporary format. Most recently, on March 11, 2025, CFZZ-FM was acquired by Arsenal Media and relaunched with a vibrant Top 40 and Hot AC format.
