The area had already been settled in 1907. The local economy revolves mostly around lumber, sugar bushes and the seasonal deer hunt. Many Bellarminois work in neighbouring Saint-Gédéon-de-Beauce.
The territory of Saint-Robert-Bellarmin is equidistant from Saint-Gédéon-de-Beauce, to the north, and Saint-Ludger, to the west, from which it is a dozen kilometers away, Saint-Robert-Bellarmin is bounded in its southern part by the border which separates Quebec of Maine. The rivière du Loup and ruisseau du Loup are the two most important watercourses in the area. A mountainous expanse, the territory of Saint-Robert-Bellarmin is dominated by Mount Sandy Stream, which rises to 950 m.[4]
