The Canton de Villeray is named after
Lous Rouer de Villeray (1629–1700). It is to the southeast of the
Petit lac Manicouagan, often over in elevation. It contains many water bodies, often small and round. A few streams run through the canton, connected to the Toulnustouc North-East River system, notably the Ruisseau Kaushkuepakau. The Northeast Toulnustouc River is fed by the Petit lac Manicouagan, and flows southeast and then south before turning west into Lac Caron, where it joins the
Toulnustouc River. The members of the Uashat Mak Mani-Utenam band of
Innu people make use of parts of the Toulnustouc River basin, including Fortin Lake, Caron Lake, and the Northeast Toulnustouc River.
Lake Arthur in the
Réserve faunique de Port-Cartier–Sept-Îles flows west into Grand lac Caotibi, which drains north into Petit lac Caotibi, a tributary of Rivière Toulnustouc Nord-Est. ==Environment==
