The southwest part of Brébeuf Lake is served by a forest road from the village of Saint-Félix-d'Otis where it connects to route 170.

Few other secondary forest roads serve the lake sector for forestry and recreational tourism activities.

The Mont du Lac Bruno (altitude: 334 m (1,096 ft)) is located at 0.2 km (0.12 mi) on the southwest shore.

He was there with Father Gabriel Lalemant when, on March 16, the Iroquois carried out a deadly attack on the Wendat (Huron) establishments.

The toponym "Lac Brébeuf" was formalized on December 5, 1968, by the Commission de toponymie du Québec.
