An Oshawa man remains in hospital with life-threatening injuries after falling off the roof of a house in Clarington while putting up Christmas lights.

Durham Police said the man, 24, was hired to put up the decorations. He lost his balance and fell to the ground, suffering severe brain and spinal injuries.

A passerby noticed him lying motionless on the home’s front lawn and called 911.

He is currently in critical condition at a trauma hospital in Toronto.
