A helicopter shuttled an elderly woman to hospital after a crash in Flamborough on Sunday afternoon.
Emergency crews arrived at the scene of a two-vehicle collision on Highway 5 near Brock Road at around 1:10 p.m.
Marc Tremblay, a commander with the Hamilton Paramedic Service, said EMS officials "had difficulty getting a patient out of the vehicle" and needed firefighters to aid in the rescue.
Ornge, the provincial air ambulance service, was called in to transport the 78-year-old woman to Hamilton General Hospital. The victim had "lower extremity injuries," said Jennifer Young, an Ornge spokesperson.
Sgt. Dave Woodford, of the Ontario Provincial Police's highway safety division, described the woman's injuries as "life-threatening."
