Trois-Rives is a municipality with an area of 675 square kilometres (261 sq mi) located in Mékinac Regional County Municipality, in the Mid-Mauricie, province of Quebec, Canada.

It is bounded on the west by the Saint-Maurice River, and includes the communities of Grande-Anse, Olscamps, Rivière Matawin (Hamlet), Saint-Joseph-de-Mékinac and partially Rivière-aux-Rats.[4] The territoiry includes also in the east portions of: Mékinac Lake (in part), "du Missionnaire" (Du Missionnaire Lake) (in part), "aux Loutres" and "Dumont". The toponym "Trois-Rives" (three banks) refers to the three rivers that drain the territory: the Matawin River, the Saint-Maurice River and the Mékinac River.


It was established in 1972 as Boucher, named after the geographic township of Boucher in which it is located. This name was chosen in honour of Pierre Boucher, former French governor of Trois-Rivières and owner of the Boucher and Boucherville Seignories in the late 17th century. It was not until 1978 that the municipal incorporation was confirmed.[1]

On December 26, 1998, the municipality was renamed to Trois-Rives (French for "Three shores") to better represent the geography of the municipality as it is crossed by three rivers: the Matawin, the Mékinac, and the Saint-Maurice River.[1]

On August 28, 2004, Trois-Rives was enlarged by some 70 square kilometres (27 sq mi) when it annexed a portion of the Lac-Masketsi Unorganized Territory.

The municipality has two main roads: Quebec Route 155 (along the Saint-Maurice River on the eastern shore); and St. Joseph road through the village of Saint-Joseph-de-Mékinac along the Mékinac River, reaching the Quebec Route 155 near the mouth of that river. The path of almost all other roads goes along the rivers. Generally, each route is designated as the place name of headwater lake that feeds it:

  1. Road Lake-to-sleighs (along the discharge of lakes Grobois, Lemere and the sleighs);
  2. Path of the domain Batchelder;
  3. Path of Mékinac Lake (along the Mékinac Lake, on the west side);
  4. Path of the river and road Crows (linking Vincent Lake);
  5. Lake Road Dumont (Dumont bypassing the lake, by the west bank);
  6. Path of Missionary Lake, which is segmented into two, the first segment links Saint-Joseph-de-Mékinac to the northern part of the lake and the second segment link the southern part of the lake, to Hervey-Jonction, Quebec;
  7. Road of the lake of the Otters;
  8. Lejeune Road;
  9. Vlimeux Lake Road.
