The place was originally an Ojibwe settlement. It was connected with the fur trade and over time it came to have a large Metis population. Over time the Metis inhabitants were redefined as being French-Canadian. The area was organized in 1850 as Warren Township, named after Ebenezer Warren, the first postmaster of the township. The settlement was called Warrenville on an 1848 map. The name was changed to Detour in 1856 when a new postmaster, Henry A. Williams, assumed office. It incorporated as a village in 1899. The spelling was changed to "DeTour" in 1953 and the post office was renamed "DeTour Village" in 1961.
