At approximately 11:30 p.m., police and other emergency services were called to Guelph Central Station for a medical assistance call. Upon arrival, officers started CPR and administered naloxone — which helps block the effects of opioids in the event of an overdose — to the man.

The man was then taken to Guelph General Hospital, where he was pronounced dead.
