A 34-year-old construction worker is in critical condition after a landslide crushed him at a Westmount job site.

The man was buried by earth after a wall that was built specifically to prevent soil from sliding gave way.

His co-workers successfully pulled him out, but the man suffered serious injuries to his upper and lower extremities, said Urgences Santé Chief of Operations Marc-André Gagnon.

Quebec's workplace health and safety board is on site investigating the incident.

Correction: A previous version of this story quoted Marc-André Gagnon as saying the construction worker had died. He is not dead, but is in critical condition.
