The injuries that led to the death of an unidentified man in the washroom of a downtown Toronto Tim Hortons coffee shop were self-inflicted, police said Tuesday.
Investigators have also determined that "the circumstances leading to the flash fire were not accidental," Toronto police said in a written statement released Tuesday afternoon.
Police said that while the injuries leading to the man's death are believed to be self-inflicted, "there are no criminal aspects to this incident."
Authorities continue to investigate the man's identity.
A post-mortem examination earlier this week revealed he died of smoke inhalation.
Police believe the man brought a can of gasoline into the men's washroom of a Tim Hortons on Yonge Street, just north of Bloor Street, at about 1 p.m. on Sunday.
Another man went into the washroom, smelled the fumes and ran out. Seconds later, customers heard a loud bang and the washroom ceiling collapsed, sending panicked patrons and employees into the street.
An unidentified male was pronounced dead at the scene with severe burns to his body. Nobody else was injured.
Police believe the fire was fuelled by a gasoline or a similar accelerant in a container the man brought into the coffee shop shortly before the blaze.
Initial reports suggested a man had entered the washroom shortly before the blaze with explosives strapped to his body.
But Toronto police discounted that theory, as well as suggestions that the man was a terrorist bomber.
Still Torontonians should not be complacent about the possibility of a real attack in Canada's largest city, security experts are warning.
Chris Mathers, a former Mountie who works as a security consultant, told The Canadian Press on Monday it was easy to fear the worst when the fire erupted.
"Given what's happening these days in the world, it's certainly not a stretch to assume that a bombing in the downtown core could be terrorist-related," Mathers said.
"I don't want to take anything lightly, but I guess if you want to strike at the Canadian heartland, Tim Hortons would be the place to go."
