Emergency crews were called to a residential building in Toronto’s Little India neighbourhood early Sunday morning for reports of a fire.

According to Toronto Fire Services (TFS), two people were trapped in a fourth floor unit when the fire broke out. Authorities say some residence attempted to save the occupants, but were unsuccessful.

Paul O’Brien, Division Commander for Toronto Fire Services told reporters on Sunday that one man in his 70s was rescued by fire fighters without vital signs. He was brought to the lobby of the building and later pronounced dead.

The second occupant of the unit — a woman believed to be in her 60s — was also rescued and is being treated for burns at Sunnybrook Hospital.

O’Brien says a third person also sustained minor injuries while escaping the fire and is being treated at a hospital.

According to TFS, the fire was contained to a single unit on the fourth floor and no other units were damaged.

The city’s fire marshal is investigating to determine the origin of the blaze.
