Emergency evacuation after false alarm aboard flight leaving Ottawa

CTV Ottawa: Plane grounded after fire alert Passengers aboard a plane taking off at Ottawa's airport had to be evacuated before taking off due to a smoke alarm light that malfunctioned

Airport officials say a burning odour and a warning light on a Canadian North flight forced an evacuation of the plane at Ottawa’s international airport Monday morning.

The Iqaluit-bound flight had 72 passengers and four crew members on board.

Krista Kealey with the Ottawa airport says a warning light came on in the cockpit alerting the pilot that there may be a fire coming from inside the plane.

The Transportation Safety Board investigated shortly after 10:30 a.m. and deemed it was a false alarm. The flight was cancelled and passengers are being put up in a hotel overnight. They are expected to fly out tomorrow.

No word on what caused the light to come on.
