A 47-year-old woman has died following a two-alarm house fire in North York Wednesday afternoon, officials have confirmed.

Firefighters were called to a home on Elmhurst Avenue, near Sheppard Avenue and Selnac Road, shortly before 4 p.m.

The call was upgraded to a two-alarm fire a short time later.

The woman was discovered without vital signs by firefighters during a search of the home.

She was rushed to hospital where she was later pronounced dead. An autopsy is set to take place Thursday. No other injuries have been reported.

“On behalf of the chief, Toronto Fire Services extends its deepest condolences to the family of the deceased,” Jim Jessop, with Toronto Fire Services, said in a media update provided Wednesday evening.

The cause of the fire was not immediately known. No other homes were damaged.

It was not immediately clear if anyone else was in the home at the time the fire began, Jessop said.

“We anticipate this post-fire inspection and investigation to certainly last at least into tomorrow morning,” he added.

An investigator with the Office of the Ontario Fire Marshal said that their work will begin tomorrow.

“(At) first light we’ll be back,” Manny Garcia told CP24 Wednesday night.

“We’re going to have a number of resources available to us here, and we’ll be going through the building systematically trying to identifying the area of origin, and to identify a cause within that area of origin.”
