The OSG is pleased to present its new choir: Le Choeur de l’OSG (COSG). This new choir, which is part of the orchestra, will join instrumentalists in choral concerts, including the closing concert of the season, in April 2022. Maestro Léveillé has brought Antonio Llaca on board to take on the role of choirmaster.

The OSG choir expects to attract singers from across the Ottawa-Gatineau region. The choir will perform regularly alongside the Orchestre Symphonique de Gatineau under the baton of maestro Yves Léveillé. Choristers will rehearse independently from the orchestra and under the baton of choral conductor Antonio Llaca. Rehearsal schedules for chorus only, as well as joint rehearsals are made available to choristers ahead of each season.
