The man was working to load a tractor onto a flatbed truck and was trapped beneath a giant wheel.
He was conscious while firefighters struggled to free him and a team of first responders tried to help him manage the pain during the hour-long rescue.
"He was aware and conscious, and he spoke with our paramedics and firefighters the whole time he was trapped,” said Robert Lamle with Urgences-Santé.
The man suffered multiple fractures and serious lacerations.
Quebec's workers health and safety board is now investigating.
