Two people suffered injuries in a three vehicle collision at 8th Line Road and Parkway Road, southeast of the city Friday.
They say a school bus is involved but there were no children on board the bus.
Marc Messier with Ottawa Fire told CFRA an elderly woman was trapped in the passenger seat in one of the vehicles.
"We had reports of one female occupant trapped in the vehicle and another male with minor injuries," said Messier. "On scene we did confirm that we did indeed have one person trapped, who was quickly extricated."
The woman was taken to hospital by ORNGE air ambulance.
