He was born in Saint-Cuthbert, Canada East, the son of Théophile Chênevert and Mathilde Filteau, and was educated in Saint-Cuthbert, at the Collège de l'Assomption, at the Collège Sainte-Marie and the Université Laval.

Chênevert was called to the Quebec bar in 1883 and practised law in Saint-Cuthbert, Berthier and Montreal, in partnership with Joseph-Émery Robidoux and then Georges-Albini Lacombe.

Chênevert founded La Gazette de Berthier in 1880 and was owner and editor until 1906.

He was defeated by Victor Allard when he ran for reelection to the Quebec assembly in 1892.
