He was born at St-Benoît, Canada East in 1854, the son of Jean-Joseph Girouard, and studied at the Collège des Sulpiciens at Montreal. Girouard qualified to practice as a notary in 1877 and set up practice at St-Benoît. He also acted as seigneurial agent for the seigneury of Lac des Deux-Montagnes for the Sulpicians. In 1879, he married Célanire, the daughter of merchant Daniel-Adolphe Plessis-Belair. Girouard was elected to the House of Commons in an 1892 by-election held after the death of Jean-Baptiste Daoust.
