It was during her studies, in 1969, that she made her debut as an actress. In 1976, she made her debut as a playwright by participating in the creation of the play , a collective creation in which she worked with Marthe Boisvert, Jacques Couture, André Saint-Pierre, and Marc Thibault. This play was staged at the Théâtre du Sang Neuf. Throughout her career, she collaborated with several Quebec theatre companies, including Théâtre Petit à Petit, Gyroscope, Théâtre des Confettis,
Théâtre d'Aujourd'hui, Théâtre de l’Œil, Théâtre de la Nouvelle Lune, Théâtre Urbi et Orbi, and Théâtre Le Clou. Her plays,

Ligue nationale d'improvisation in 1981. In addition to being a playwright, she has written for radio, television and film. On September 23, 2016, Bombardier was invited to the show
Plus on est de fous, plus on lit! (The more the merrier!). She denounced Quebec theatre and cinema, which, according to her, leaves no room on stage or on screen for women who are aging. She criticized the fact that actresses often die tragically, thus leaving their place on screen or on stage to younger women. She was offended by the fact that at 63, she no longer has the chance to act or, when she does, her character dies early in the story. ==Awards and honours==
