A graduate of National Theatre School of Canada in 2010, Etienne was quickly noticed by the Théâtre de La Pire Espèce company. He has worked on many of their shows, including Ubu sur la table, Petit bonhomme en papier de carbonne, Roland, la vérité du vainqueur and Léon le nul, the last two in which he played the lead role. This collaboration has led him to constantly perform across Canada as well as in Europe.

On TV, we saw him in T'es où Theo, a youth show in which he had a starring role, as well as in Trauma and France Kbek, a french series shot in Paris and broadcasted on OCS. We were able to appreciate his talent in the popular District 31, where he played the role of agent Francis Desmarais. Recently, he has made appearances in the series L'échappée, STAT and Les Bombes.
