It's believed an overnight fire at a home in Etobicoke may have been deliberately set.
Firefighters were called to a home on Beta Street, near Evans Avenue and Browns Line, around 3:20 Wednesday morning.
They arrived to find flames shooting high into the air.
Officials say the two homes on either side were evacuated. One of them is home to an elderly woman on oxygen. She and everyone else made it out safely.
Neighbours say there was a much smaller fire at this same house last week.
