Sharon, a French-Canadian Métis, was born in the mining city of Timmins, Ontario. She began her career as a fashion model, at which she was successful until contracting a bad case of pneumonia, which caused her to lose a lot of weight.
Soon after her recovery she began training with weights to regain the weight she needed to get back to modeling. After achieving a somewhat toned build, she was rejected at model agencies for being oversized. She then decided to give up modeling and dedicate herself to bodybuilding.
Sharon became one of the most famous women in the sport, leading to frequent photo shoots and several covers for magazines like Muscle & Fitness and Flex.
Currently Bruneau is pursuing an acting career, though she still models for fitness pictorials occasionally. She has had roles in releases such as Tornado Run, Nemesis 2: Nebula, Nemesis III: Prey Harder, and R.S.V.P..
