The Transportation Safety Board's investigation into a runway crash between two planes will examine whether a major airline followed its evacuation protocols.
Officials say an empty Sunwing plane struck a WestJet aircraft, which was carrying 168 passengers and six crewmembers, while both planes were on the tarmac.
A spokeswoman for WestJet says everybody was safely evacuated from the plane via emergency slides and nobody on board was injured.
But Ali Alagheband, an engineer from Toronto, says chaos erupted when the plane was struck and a fire started outside.
He says he was in a seat opposite the part of the plane that was struck, and he wasn't able to hear instructions from crewmembers or the pilot over the commotion.
Alagheband says he heard conflicting instructions from people around him about whether to stand up and start making his way to the exits or sit back down in his seat.
