Turcotte was elected in a 1907 by-election held after Charles Ramsay Devlin resigned his seat to become a member of the Quebec cabinet.
He was reelected in the 1908 federal election but was defeated when he ran for reelection in 1911.
He was married twice: first to Jeanne Leblanc and then to Emma, the daughter of Charles-Édouard Houde.
His illegitimate brother Arthur served in the Quebec assembly and was mayor of Trois-Rivières.
