Who is leading the investigation of the recent plane crash?

The investigation is being led by the Canadian Transportation Safety Board, as this is primarily a Canadian operation occurring on Canadian soil. While U.S. agencies including the NTSB and FAA are providing assistance, they are not in charge of the investigation process. Tom Costello emphasizes this jurisdictional point, noting that despite American involvement and support, the investigation remains under Canadian authority. Investigators are currently examining debris on the airfield, with multiple runways closed as they piece through the remains of the regional jet.
