The man was walking by the site at De la Montagne Street and Rene-Levesque Boulevard when he was hit by the piece of metal at around 8:20 a.m.
“He was in a critical state and transported rapidly to hospital,” said Bob Lamle of Urgences-Santé.
A short time later, police confirmed the man had died.
The man was a passerby and not a worker, Lamle said.
More to come.
