Toponymy
This toponymic designation appears on regional map number 3, 1943. The name "Grand lac à Jack" appeared on maps at the beginning of the 20th century. The origin of the toponym remains uncertain. However, the presence of an Amerindian named Jacques Bacon, who spent the summer camping in these areas with his family, several decades ago, could be linked to the origin of this body of water. The construction of the Lac-à-Jack dam allowed the passage of a road that links the Jacques-Cartier lake sector to the Grands-Jardins conservation park. This name was approved on April 3, 1959, by the Commission de géographie du Québec. Grand lac Jack and Grand lac à Jack are variants of the official name.. The toponym "Lac à Jack" was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
