He was born in Edwardsburgh (Cardinal) in Upper Canada in 1817 and studied at Potsdam, New York.
In 1861, he defeated Edmund Heath to become the representative for Pontiac County in the legislative assembly; he was reelected in 1863.
His nephew and son-in-law, William Joseph Poupore, also represented Pontiac provincially and federally.
