One man is dead after fire tore through a condo unit in downtown Toronto.

Investigators said the fire broke out just before 4:30 a.m. Friday in the living room of a sixth-floor condo unit on Richmond Street East, near Jarvis Street.

Firefighters found the unidentified man’s body near the unit’s door.

Capt. Mike Strapko of Toronto Fire Services saidthe man was discovered without vital signs.

Paramedics attempted to revive the man with CPR, but he eventually succumbed to his injuries and was pronounced dead on scene.

The cause of the fire is not yet known.

Strapko said the fire was contained to one condo unit, but as a precaution there was a partial evacuation of the building. The Toronto Transit Commission was initially asked for buses to shelter the evacuees, but the request was cancelled in favour of using a meeting room on the second floor of the high-rise.

Twelve fire trucks and 45 firefighters responded to the two-alarm fire, said Strapko.

An investigator with the Ontario Fire Marshal’s office is looking into the cause of the blaze.

The condominium building at 225 Richmond St.East is advertised as having both typical condo units and two-storey lofts with an upper floor bedroom.

The victim lived in one of the two-storey units, CP24’s Cam Woolley reported.
