The attack happened around 12:30 a.m. Tuesday in the Kennedale Ravine just north of Hooke Road.
Calling it a ‘brutal assault,’ police say the 43-year-old was found with extensive injuries causing a ‘significant loss of blood.’
The man was taken to hospital where he remains in serious condition.
Investigators say the attacker is described as a slim Caucasian man, around 20 years old with blond hair and blue eyes. They say the man may have been with a Caucasian woman wearing blue pants and a blue shirt and a third individual who has not been described at the time of the attack.
“This appears to be a cowardly, unprovoked attack on a helpless man,” said Acting Det. Mark Rosenow in a message on Friday.
“We believe the man was struck repeatedly with a weapon of some kind, and from the nature of his injuries, he was most likely trying to defend himself. This man will be in hospital for some time recovering, and he’s lucky to be alive.”
Anyone with information about the attack is asked to call the police or Crime Stoppers.
