His debut one-man show, A New Comic is Born, ran for more than five hundred performances and earned him two Felix nominations. It was first performed in Montreal in 1989. His second, The New Adventures of Michel Courtemanche, first performed in 1992, filled theatres in both North America and Europe and spawned his second international hit video (1993).
Courtemanche has internationally sold out large theatres, and has inspired a hardcover comic book. Courtemanche appeared in Québécois films Nuit de Noces and Karmina 2, and on the Secret Adventures of Jules Verne television series, on American pay television channel Syfy.
His style of comedy can be described as mime combined with sound effects, as he is most often seen interacting with invisible objects or even people and using his voice to complete the scene. He is also known for making remarkable grimaces.
In 2002, he moved from acting to working behind the camera. His production company, Encore Télévision, produces the French-Canadian edition of the sitcom Caméra café, which was adapted from French television.
