French-Canadian mezzo-soprano Justine Ledoux has been praised for her “haunting, smoky tonality” and for “a command of her lower and higher register that make for thrilling artistry” (Opera Canada). Named one of CBC’s 30 Hot Canadian Classical Musicians Under 30 in 2025, she is a recent graduate of the Atelier lyrique de l’Opéra de Montréal and the recipient of the 2025 Choquette-Symcox Award and the 2026 Mécénat Musica Voice Discovery Prize.

The 2025–26 season saw Justine make her title-role debut as Carmen with FestivalOpéra Saint-Eustache, following her work covering the role at Opéra de Montréal. She also covered Esmeralda in Notre-Dame de Paris with Festival Classica and was selected as one of eight finalists, and the only Canadian finalist, at the 2026 Vienna Opera Competition. In August 2026, she joined the Académie Francis Poulenc in Tours, an opportunity awarded following her Prize for Best Interpretation of French Mélodie at the 2025 Concours OSM.

Recent operatic highlights include Rosina in Il barbiere di Siviglia with Brott Opera. During her residency at the Atelier lyrique de l’Opéra de Montréal, she performed Pastuchyňa in Jenůfa, Mrs. Grose in The Turn of the Screw in collaboration with the National Arts Centre Orchestra, and the Teacup and Dragonfly in L’Enfant et les sortilèges, in addition to covering Rosina in Il barbiere di Siviglia. An alumna of Calgary Opera’s McPhee Artist Development Program, her previous roles include Wellgunde in Das Rheingold, Marcellina in Le nozze di Figaro, Béatrice and Ursule in Béatrice et Bénédict, and Mercédès in Carmen.

Equally at home on both opera and concert stages, Justine premiered Stefan Hakenberg’s States of Matter in May 2024 alongside modern orchestrations of Mahler works as part of a project initiated by the Wirth Institute for Austrian and Central European Studies, with performances in Edmonton, Canmore, and Calgary. She has also appeared as a featured soloist with Chœur Massenet in Kim André Arnesen’s Magnificat and Eric Whitacre’s Five Hebrew Love Songs.

Her notable achievements include two residencies at the Banff Centre for Arts and Creativity, where she performed Serena Joy in The Handmaid’s Tale and Rachel in a workshop of Adoration by Mary Kouyoumdjian and Royce Vavrek in collaboration with Beth Morrison Projects. In 2025, she won the Prize for Best Interpretation of French Mélodie at the Concours OSM and Third Prize at the Prix d’Europe, where she also received the Claire-Charbonneau-Clerk Award for her outstanding artistic and technical qualities. A laureate of the Jeunes Ambassadeurs Lyriques, she has also appeared at the Wartburg Castle Gala in Eisenach, Germany. 

Justine continues to refine her craft under the mentorship of Lena Hellström-Färnlöf at the Academy of Music and Opera at Mälardalen University in Sweden. She holds both Bachelor’s and Master’s degrees in Vocal Performance from the Conservatoire de musique de Montréal.

“Justine is a singer that has a very strong intuition for interpretation. She doesn’t stay on the surface of things, she knows how to get into the character of someone else with empathy and depth.” Suzanne Lantagne

“Justine Ledoux’s Rosina started out with haunting, smoky tonality in “Una voce poco fa,” contrasting sharply with her soaring high notes at the end of that same piece. Ledoux’s command of her lower and higher register made for thrilling artistry throughout the opera.” Dawn Martens, Opera Canada

“Justine Ledoux, whose opulent and promising mezzo voice leaves a lasting impression, brings remarkable depth to the role of Mrs. Nolan.” Louis Bilodeau, L’Opéra
