A man is dead after being shot by Peel police at Toronto Pearson's Terminal 1 Thursday morning. 

The shooting happened shortly before 7 a.m. after police received a call from a member of the public about a dispute involving two or three people, Peel police Chief Nishan Duraiappah said. The group knew each other and was there "for the purposes of travel," he said. 

Three officers responded to the call. Police had been attempting to mediate the dispute for around 10 minutes when the man abruptly took out a firearm and pointed it at an officer, he said. 

The man was "in distress" and had been in an SUV at Terminal 1 departures, but the shooting happened outside the vehicle, the SIU said.
