Rochon's early life was fraught with tragedy and misfortune. After her parents were deemed unfit to raise her, she was remanded to foster care at age 10. Shuttled from one foster home to the next, Rochon ran away to Vancouver. When she was 14 and still homeless, she was attacked and robbed by a homeless man, who assaulted her with a knife and slashed her on her upper right arm, leaving Rochon with a large vertical scar. In 2004, Rochon won MicroCinemaFest's "Best Comedy Actress" award for her work in Dr. Horror's Erotic House of Idiots.
