At least two other people were injured in the incident.
Around 1 p.m. Friday another Cessna 152 registered to the school, call sign FGOI, was taking off from the airport.
A security perimeter was set up near the shopping centre yesterday. One of the pilots is asked to turn left to avoid traffic.
"I looked up and one of them was making a odd sound".
When the controller received no response, he repeated his warning.
Nheil Martinez, who works inside the shopping centre, told the Canadian Press he saw the shadow of a plane and heard its motor before hearing a loud boom. The name Cargair could be seen on parts of the plane in the parking lot.
Pelchat, a nurse, went to help the 21-year-old pilot.
The 23-year-old pilot of GPNP was more fortunate.
The Transportation Safety Board of Canada announced it was deploying a team of investigators to the site.
Longueuil police spokesperson Jean-Pierre Voutsinos said earlier that two people had been taken to hospital but the nature and extent of their injuries was not yet known.
The man who died had a student-pilot permit and had 40 hours of flight time after seven months at the Cargair pilot academy, Adams said.
Cargair trains over 200 pilots a year, with around 140 of those students coming from China.
Adams also suggested that the flawless flying conditions on Friday meant there was likely a lot of air traffic around the airport. They will also review the tower-pilot communication, as well as radar data showing the planes' flight paths.
