Charles-André "Chuck" Comeau (born 17 September 1979) is a French Canadian musician, who is best known as the drummer for pop punk band Simple Plan.
Comeau started his music career in Reset with fellow bandmate Pierre Bouvier. After the band's first CD was released, Comeau left the band and went to McGill University to pursue a degree in law, intending to follow in his father's footsteps as a lawyer.
After reuniting with Bouvier at a concert, he soon left school and helped his friend to form Simple Plan. In Simple Plan, Comeau, along with Bouvier, are the main songwriters. He is sometimes known as the "writer" of the band as he does most of the lyrics, writes all the concepts, and writes the scripts to Simple Plan's music videos.
He is co-owner of Role Model Clothing, along with Pierre Bouvier and Simple Plan's webmaster, photographer, and videographer Patrick Langlois. The line mostly markets shirts, which invariably include the words "ROLE MODEL" in the design.
