Onésiphore Carbonneau (June 17, 1852 – February 25, 1932) was a merchant and political figure in Quebec. He represented L'Islet in the Canadian House of Commons from 1902 to 1908 as a Liberal.[1]
He was born in Berthier-en-Bas, Canada East, the son of J.O. Carbonneau and Soulange Dion, and was educated there. In 1874, he married Adele Turgeon.[2] Carbonneau ran unsuccessfully for the Montmagny seat in the House of Commons in 1878. He was first elected to the House of Commons in an 1902 by-election held after Alphonse Arthur Miville Déchêne was named to the Canadian senate. He was defeated when he ran for reelection in 1904.[1]
