Toponymy
Probably called "S. Antoine river" by Samuel de Champlain on his 1632 map, and "R. de S. Anthome" by Jean Boisseau, in 1643, the South river "seems to appear on the map from Jean Bourdon, drawn up around 1641, in the form of Grande Rivière du Sud. The act of concession of the seigneury of Rivière-du-Sud to Charles Huault de Montmagny, in 1646, expressly states "the river called from the South to the point where it discharges into the Saint Lawrence River. Very stable thereafter, the toponym is part of the official designation of three municipalities drained by this course of water: Saint-Pierre-de-la-Rivière-du-Sud, Saint-François-de-la-Rivière-du-Sud and Sainte-Euphémie-sur-Rivière-du-Sud. The toponym Rivière du Sud was formalized on December 5, 1968 at the Commission de toponymie du Québec.
