One person has been taken to hospital after suffering burns in an apparent "gas explosion" at a condo building on East Liberty Street, Toronto police say.
Police, firefighters and paramedics are attending the scene at 85 East Liberty St.
The injured person suffered minor injuries, police say.
Sgt. Jeff Zammit estimated that "hundreds" of people had to be evacuated from the building following the explosion. But all were allowed to return within a couple of hours.
Firefighters say the explosion occurred on the sixth floor of the building. The doors of an elevator were blown out, along with the windows surrounding it.
The fire investigation is ongoing. The fire marshal has been notified.
