Ozias Leduc (October 8, 1864 - June 16, 1955) was one of Quebec’s early painters. He was born in the city Saint-Hilaire de Rouville. Leduc produced many portraits, still lives and also landscapes, plus religious works. He is best known for his work decorating the Notre-Dame-de-la-Presentation church along with Shawinigan South, a project which took him thirteen years to complete. Leduc lived a very lonely life at his home town and was dubbed “the sage of St-Hilaire”. He died in the Saint-Hyacinthe in 1955.

Leduc was chiefly self-taught. Around 1880, he worked with the Luigi Cappello, an Italian painter, on the church decorations. Around 1881, he was employed at the Carli, a manufacturer of statues in the Montreal. Around 1883, he also worked with Adolphe Rho; adorn another church, this time in the Yamachiche, Quebec. After that, he then started working on his own on church decorations. Leduc made a short trip to Paris and London during 1897 along with Suzor-Coté, where he was influenced by some impressionists.

Leduc also received an honorary doctorate from the University de Montréal during 1938. His legacy includes teaching Paul-Émile Borduas.
