Four people were airlifted to hospitals across Cape Breton after a bus drove off the Cabot Trail highway Sunday afternoon and ended up on its side.
The RCMP in Nova Scotia say 10 people were injured in the crash and one passenger suffered serious injuries.
The Cabot Trail, a scenic route used by tourists, was closed Sunday afternoon after the bus carrying 20 passengers rolled onto its side about three kilometres south of Neil's Harbour.
"It was very serious for the people involved but it could have been a lot worse," said Greg Organ, chief of the Neil's Harbour-New Haven Volunteer Fire Department.
Organ said the crash happened on an accessible section of the highway to firefighters, who used the Jaws of Life to rescue passengers.
"There are many, many places where if the bus went off the road it would be a recovery," he said, describing the numerous steep slopes along the scenic highland highway.
Organ said the bus's licence plate was from Pennsylvania and most of the passengers were senior citizens.
The Mounties restricted public access to the Cabot Trail while police, fire and medical crews responded to the accident.
Police said the bus was removed and the trail was re-opened to traffic early Sunday evening.
