He was born in Saint-Simon, Canada East, the son of Flavien Dupont and Nathalie Fournier.

Dupont was educated at the Séminaire de Saint-Hyacinthe, was admitted as a notary in 1873 and set up practice at Saint-Liboire.

He was elected to the House of Commons in an 1882 by-election held after Joseph-Alfred Mousseau became Quebec premier.
