Emergency crews are still dousing hot spots after a fire Wednesday morning destroyed a home in the central city.

All tenants in the two-and-a-half story building, which served as five rental units, are accounted for, said Fire Information Officer, Claudio Mostacci.

More than 10 fire trucks were called to 190 Ray St. N., near York Boulevard, just after 5 a.m.

"It (fire) was fully involved when we got on the scene," Mostacci said, adding that the blaze started in the front of the home.

Firefighters launched a search and rescue but were forced to pull out when the roof partially collapsed.

A few of the tenants suffered smoke inhalation and were treated by paramedics.

Hydro crews have cut off power to the street.

The Office of the Ontario Fire Marshal has been called in to investigate.

Mostacci says it's too early to determine a damage estimate. Officials were told the stone house has once used as additional housing for soldiers of the armouries.

Neighbours say the property was not well-kept with bulk garbage, like sofas and debris, constantly littering the front lawn.

Charred debris could be seen on the front lawn following the blaze.

Police have closed Ray from Barton Street to York to allow for emergency vehicles.
