Theatre gave Madeleine her initial momentum in the artistic world. She first performed at Théâtre de Quat’Sous in À quelle heure on est mort, directed by Frédéric Dubois, followed by Brillante at Théâtre Denise-Pelletier, written and directed by Clara Prévost. In 2023, ROME, directed by Brigitte Haentjens, offered her a unique take on the character of Cleopatra, from whom she drew great freedom. She was also part of the cast of UN DEUX TROIS (a cross-Canada tour) and Classique(s) at Théâtre du Nouveau Monde, both directed by Mani Soleymanlou. During her training at the National Theatre School of Canada (2020), she met Catherine Vidal for the first time. The two would reunite a few years later for an adaptation of The Seagull at Théâtre Prospero. In winter 2026, she will appear in Boîte Noire, directed by Justin Laramée at Théâtre Duceppe.

A lifelong fan of fiction and constantly seeking versatility, she also shares her career between film and television. She can be seen in the series Cerebrum, Indéfendable, and Toute la vie, as well as in the films Frontières and Les jours heureux, and soon in Nervures by Raymond Saint-Jean.

In 2023, Madeleine began voice training and has since fulfilled her desire for versatility by working on various voiceover, dubbing, and commercial projects.
