Until July 6, 1996, Lac-Granet was a large unorganized territory encompassing 1,320.5 km2 (509.8 sq mi). On that day, most of it was added to the City of Val-d'Or. It retained only two small non-contiguous areas totalling 303.81 km2 (117.30 sq mi), of which its western part was a small section of land straddling the north shore of Lake Lemoine and its eastern part is an almost square tract surrounding Lake Granet, mostly part of the La Vérendrye Wildlife Reserve.
On August 29, 2009, Lac-Granet was reduced in size again when its western portion, together with the Unorganized Territory of Lac-Fouillac, were added to the Municipality of Rivière-Héva.[4] The remaining territory is uninhabited.
