Lake of Two Mountains (French: Lac des Deux Montagnes) is part of the river delta widening of the Ottawa River in Quebec, Canada, at its confluence with the St. Lawrence River.

Origin of the name

The lake was named lac des Médicis in 1612 by French explorer Samuel de Champlain, then renamed lac des Soissons about 1632. By around 1684 French colonists named it as Lac des Deux Montagnes. The name refers to Calvaire Mountain and Saint-Joseph-du-Lac Hill, the two highest peaks of Mont Oka that face the lake on its northern shore.
