A bus with 17 passengers rolled on a northwestern Alberta highway Wednesday morning.

The crash happened around 7 a.m. on Highway 672, northwest of Grande Prairie.

Emergency responders treated people with both serious and minor injuries, and STARS Air Ambulance attended the scene, according to Mounties.

Acute Care Alberta confirms four of the passengers were hospitalized with life-threatening injuries, while the rest suffered non-life threatening injuries.

The passengers were oil-and-gas workers headed to Grande Prairie. Their departure location is unknown.

RCMP officers at the scene confirmed the bus veered off the road into the ditch, and flipped back onto the road as it rolled over.

Alcohol, speed and weather are not considered factors.

The highway was closed between Range Roads 90 and 92.
