Ontario Provincial Police are continuing to investigate a single vehicle collision west of White River.
The Marathon and Manitouwadge detachments say the incident occurred around 1:20 Saturday afternoon, with officers finding a silver car on the westbound shoulder of Highway 17, about 30 kilometres west of White River, near White Lake Narrows Bridge - the vehicle had been travelling west when it left the roadway, coming into contact with a rock.
Officers found a male walking around on the roadway and another laying on the roadway, with both taken to hospital for further treatment - a 28-year-old from Pic Mobert was treated for minor injuries and released while a 27-year-old from Batchewana First Nation was airlifted in critical condition to Thunder Bay for further treatment.
The highway was closed for about 3.5 hours before reopening to one lane, and has since fully reopened.
