An IBM Canada staff member jumped to his death at the company's Markham headquarters, according to police.

The man, 48, from Toronto, was on mental health leave, according to a police source, who said he returned to the workplace and climbed to the seventh floor Tuesday.

Before police were called at about 11:30 a.m., the service said the man plummeted off the ledge, located above the building's indoor atrium at 3600 Steeles Ave. E.

The man was taken to hospital, according to police Const. Andy Pattenden, who explained he eventually succumbed to his injuries. The coroner has since confirmed the death was the result of suicide.
