Plane crashes in Canada's Northwest Territories, fatalities confirmed

A small airliner registered to Northwestern Air Lease crashed near Forth Smith in Canada's remote Northwest Territories on Tuesday, killing some people on board.

There were no details on how many people died or how many had been on board but the premier of the Northwest Territories put out a statement mourning those lost in the crash.

"It is with a heavy heart that I express my deepest condolences to the families, friends, and loved ones of those who were aboard the Northwestern Air flight that crashed outside of Fort Smith today," Premier RJ Simpson said.

Chief coroner of Northwest Territories Garth Eggenberger confirmed there were fatalities but said officials would not be providing any further information until next of kin are notified.

The Royal Canadian Mounted Police did not immediately respond to requests for comment.

The Fort Smith Health Centre said it activated its mass casualty protocol at approximately 8:50 am in response to "an aviation incident near the community," to free up resources to respond.

Three Royal Canadian Air Force squadrons supported search and rescue efforts for the aircraft, which was found near the Slave River after it lost contact shortly after take-off near Fort Smith, said Maxime Cliche, a public affairs officer with the Canadian Armed Forces.

A team of investigators has been deployed to look into the accident involving a BAE Jetstream aircraft, TSB said, adding that it was gathering information.

The crash comes a day after three people were killed and four others seriously injured in a helicopter crash in neighboring British Columbia.
