Toronto police say they're treating a death at Spadina Avenue's Hotel Waverly as suspicious, but it's not a homicide investigation at this time.

A person was found dead inside a room at the historic Hotel Waverly, on Spadina Avenue just north of College Street, on Tuesday.

The adjacent rooms were evacuated while firefighters entered the room wearing ventilators to take air samples.

Sgt. Scott Villers, of 14 Division, said homicide detectives have been notified about the death, which is the standard procedure for any suspicious death.

The coroner is heading to the scene, Villers said, and a cause of death is expected to be released tomorrow.

The Hotel Waverly opened in 1900 and has been in continuous operation since.
