TORONTO -- A homeless male living in a wooden shelter in an encampment east of downtown Toronto was killed when the makeshift structure he was in caught fire on Wednesday morning.

Toronto firefighters say they were called to an encampment in Orphans Green Park, near Adelaide Street East and Power Street in Toronto's Corktown neighbourhood, after 6 a.m. for a fire.

"Toronto Fire Services responded to the report of a fire, a very visible fire, at this location. Upon arrival, our crews were met with a fully involved structure fire," Deputy Fire Chief Jim Jessop said on Wednesday morning.

He noted that a small wooden structure had caught fire in the park.

"The fire was quickly extinguished, unfortunately once the fire was extinguished, our crews conducted their search inside and noted one deceased person," he told reporters at the scene on Wednesday morning.

A construction worker told CP24 he watched fire crews spray the small structure, extinguish it, and then rush to rip it apart once they realized there was a person inside.

Police added that no one else was present at the encampment when emergency crews arrived.

The wooden structure that caught fire was coated both inside and out with some form of insulation.

Police have not released the name of the deceased.

Fire officials said the Office of the Fire Marshal (OFM) has been called to the scene to investigate. Speaking to reporters on Wednesday, a spokesperson for the OFM said it is too early to say what caused the deadly blaze.

Area residents say the encampment has been at the dog park for most of the winter. Overnight, the wind chill was forecast to hit about -22.

Jessop said public education staff have visited the encampment three times in the last number of months to offer fire safety advice.

He added the fatal fire marks the 27th fire crews have responded to at encampments in the city this year.

"I think Toronto Fire Services has been very clear... there are fire and life safety risks associated with these types of structures," he said Wednesday.
