Marc Marut was born in Winnipeg, Manitoba. His parents immigrated to Canada—his mother from England and his father from France. When he was three, his family moved to Oakville, Ontario, where he attended École Ste-Marie. He went on to attend Appleby College and Oakville Trafalgar High School, but never pursued any post-secondary education.
When he was nine, his father persuaded him to audition for a production of "Les Misérables" as an easy way to obtain a badge for Cub Scouts. Marc landed the role of Gavroche and subsequently had to quit Cub Scouts due to the requirements of the play. His mother took the reins of her son's newfound career, and was instrumental in his success as a child actor. Marc began landing roles in television series after his departure from "Les Misérables", and became established as one of the busiest young actors in Toronto.
Marc lives near Toronto, Ontario, with his son and continues to pursue all of his creative passions including acting, music, writing, video production, and visual effects.
