The Jean-Boivin River is a freshwater tributary of the Cyriac River, flowing in the unorganized territory of Lac-Ministuk, in the Le Fjord-du-Saguenay Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in province from Quebec, to Canada. The upper and intermediate course of the Jean-Boivin river crosses the Laurentides Wildlife Reserve.
The Jean-Boivin River is accessible by the route 175; other secondary forest roads have been developed in the sector for the needs of forestry and recreational tourism activities.[1]
Forestry is the primary economic activity in the sector; recreational tourism, second.
