The station has a contemporary hit radioformat and is part of the Énergie network which operates across Quebec. It started operations on August 27, 1979. CIGB-FM became wholly owned and operated by Radiomutuel (predecessor of Astral Media) in 1987, as the company bought the station, which became a sister station to the now-defunct CJTR 1140 AM (also in Trois-Rivières).
