The river's name comes from the Ojibwa word Wahnabitaybing, or "tooth", which describes the shape of Lake Wanapitei. A community which takes its name from the river is spelled Wahnapitae. However, the Wanapitei spelling is correct for both the lake and the river.
The French River (or Rivière des Français) is a river in central Ontario, Canada.
The river follows the boundary between the Parry Sound District and the Sudbury District, and in most contexts is considered the dividing line between Northern Ontario and Southern Ontario.
Because of the rugged nature of the Canadian Shield country surrounding this river, large parts of this river remain relatively untouched and it is now a popular location for recreational canoeing, kayaking, fishing and boating.
