Jean-Moïse Martin obtained his diploma from the National Theatre School (NTS) of Canada in 2006. The intensity of his acting, as much physical as it is instinctive, and his distinct voice, rapidly makes him stand out. Being a talented singer as well, he received the Luc Plamondon grant from the NTS.

On television, we have had the pleasure of seeing him in Cerebrum, Nuit Blanche, Fourchette, Nous, Larry and Sorcières. He is nominated at the 2016 Gémeaux Prize for his interpretation of Simon Phaneuf in Lâcher Prise. In addition, he has played roles in Blue Moon, Victor Lessard and Les beaux malaises. On the big screen he was part of many projects, notably Cruising bar II (Robert Ménard), Pour l'amour de Dieu (Micheline Lanctôt), Nelly (Anne Émond) Trip à 3 (Nicolas Monette), Babatoura (Guillaume Collin) and Des hommes la nuit (Anh Minh Truong).

On stage, he has worked with a multitude of renowned directors such as Serge Denoncourt, in Cyrano de Bergerac, Roméo et Juliette, Edmond, all presented at the Théâtre du Nouveau Monde, as well as Un tramway nommé désir at Espace GO. Over the years, through many productions of the Orange Noyée Company, Jean-Moïse has developed a fruitful collaboration with Mani Soleymanlou, particularly in Trois, Ils étaient quatre, and Huit. In 2018, he worked under the direction of Robert Lepage in Coriolan, and delivered a striking part in Oslo, directed by Edith Patenaude, at the Théâtre Jean-Duceppe.

He returns on the Espace Go stage, directed by Solène Paré in La Brèche, where he plays the incredibly difficult character of Frayne. In 2023 at Usine C, he embodies Antoine in the ambitious ROME by Brigitte Haentjens, a re-imagining of five Shakespeare plays in a translation by Jean-Marc Dalpé.
