Marie-Claude Gaudet is originally from the South Shore of Montreal and is the sixth child in a family of eight children. She studied geography at Laval University in Quebec City. She made the 1980 Olympic selection for Canada in rowing and won the silver medal at the Pan American Games in 1983. She is giving back to the sport today by being a national referee in rowing.

Marie-Claude has been in business for nearly 30 years, and acted as a real estate agent in Longueuil for about fifteen years. She then worked as a farmer on a small farm in Mauricie where angora goats were raised and where she learned to work in the forest with horses. In recent years, Marie-Claude has been a financial security advisor in Trois-Rivières and Gatineau.

Marie-Claude has been involved in politics since 2009, when she was a municipal councillor in Sainte-Geneviève-de-Batiscan until 2013. Since that experience, Marie-Claude has always promised herself to take another step forward in politics. Financial insecurity previously forced her to stay away from politics, and she is excited her current situation allows her to make this new commitment. Marie-Claude has, so to speak, politics in her genes: her maternal grandmother, Marie-Anne Levaque, fought alongside Idola Saint-Jean for women's right to vote in Quebec in the 1940s.

Marie-Claude decided to run for the Green Party because she believes that voters are ready to support a party whose main objective is to protect the environment and build a prosperous carbon-free future. She plans to work on this mission with all her heart.
