One woman is dead and a second person is in hospital after a small helicopter crashed just east of Kitchener-Waterloo late Monday morning.
Authorities haven't released any information about the victims.
The second person, believed to be a man, was transported to Grand River Hospital in Waterloo and then airlifted to a trauma centre in Hamilton with spinal injuries.
Two people were on board the aircraft when it crashed into a retaining pond at Region of Waterloo International Airport at about 11:30 a.m., said John Prno, director of Waterloo Region EMS.
The helicopter was partially submerged in water after it went down near some hangars, but the occupants weren't trapped in the aircraft, Prno said.
In an interview with CP24, Waterloo Regional Police spokesman Olaf Heinzel described the crash site as "a swampy area."
There are unconfirmed reports the helicopter crashed into trees and power lines.
The helicopter, a Robinson R22, was owned by Great Lakes Helicopter, a training school and charter service that operates out of the airport.
Great Lakes Helicopter refused to comment on the crash.
The Transportation Safety Board has been called in to investigate the cause of the crash.
