Toponymy
The toponym "Lac Launière" appears on a map of the Laurentides National Park. The origin of this acronym is probably attributed in memory of a family of gamekeepers who lived in the lake at Christmas, south of L'Étape. The toponym "Rivière Launière" was formalized on December 5, 1968 at the Place Names Bank of the Commission de toponymie du Québec.
