Two of three people have been taken to the hospital after a small plane crashed into a tree near Ottawa International Airport on Thursday afternoon.

First responders said the plane struck some power lines as it approached the airport before crashing into a tree along Riverside Drive near Hunt Club Road.

Marc-Antoine Deschamps, a spokesman for the city’s paramedics service, said it took “significant effort” to get the people out of the aircraft.

An adult woman and an adult man were pulled from the Grumman AA-5A aircraft while first responders were still trying to extricate a third person.

“At this time, I can confirm that two occupants of the airplane were taken to the hospital in stable condition with non-life-threatening injuries,” Deschamps said.

He said he could not release any information about the third occupant.

Ottawa police said road closures were in effect and the public was asked to avoid the area.

Krista Kealey, a spokesperson for the Ottawa International Airport Authority, said the airport’s fire service responded to the crash along with city firefighters.

Kealey added that airport operations were normal.

The Transportation Safety Board of Canada is investigating the crash.
