While removing a wrecked car after the conclusion of today's race, a track worker fell into the path of a crane, killing the man.
The FIA is reporting a track worker at the Circuit Gilles Villeneuve has died after being run over by a crane trackside.
The man was assisting in retrieving Esteban Gutierrez's wrecked car after the end of the race. He tripped and fell under the wheels of the crane carrying the car when trying to retrieve a dropped radio and was run over.
Reports state that the man was quickly brought to the track care centre, but was sent to Sacre-Coeur Hospital in Montreal for treatment in its traumatology department.
Efforts to help the man were unsuccessful and he succumbed to injuries Sunday night.
"The worker was helping to recover a car, which had stopped during the race," F1's Matteo Bonciani said at the track.
"The recovery vehicle had lifted the car to return it to the pits and while doing this the worker dropped his radio and attempted to pick it up. As he did this, he stumbled and was hit and run over by the recovery vehicle."
The unidentified man is the third marshal to have been killed since 2000.
