Trained at the National Theater School of Canada, Etienne Lou is a dancer and actor. You could have first noticed him in the short film Chinatown by Guillaume Cyr in 2016. 

Amongst his numerous prizes and distinctions in dance, in the "popping" discipline, Etienne shines as well in theater. In particular, we saw him him in Jon Lachlan Stewart’s L’homme boîte in 2016, as part of the Zone Homa festival. During fall 2017, Etienne starred in Martin Faucher's Jusqu’où te mènera Montréal during the Festival du Jamais Lu. In 2018, Etienne crossed over to the European continent to perform at the Théâtre de la Colline in the play Notre innocence by none other than Wajdi Mouawad. During summer of the same year, he "visits" the parks of Montreal with the traveling theater La Roulotte for the play Asteroid B-612.

In 2019, Etienne was part of the cast of La société des poètes disparus, a play staged by Sébastien David at the Théâtre Denise-Pelletier, as well as in L'Énéide performed at the Quat'sous theater. He walks the stage of the Théâtre Jean Duceppe in 2023 with the plays Showtime, une grosse pièce de théâtre and Le Projet Riopelle. In collaboration with Gabriel-Antoine Roy, he created the play La Grande Masquerade, in which he performs an interdisciplinary performance, presented at the Théâtre La Chapelle in 2024.

He has made a name for himself on television in shows such as Caméra Café, Toute la vie, Plan B, Lac Noir, Portrait robot and Anna et Arnaud. He continued his TV appearances in 2023, landing roles in Inspirez-Expirez, L'oeil du cyclone and Contre-Offre.
