In high winds, Toronto Fire crews had to battle what became a four-alarm fire at a luxury mansion in the Bridle Path neighbourhood.
Seventeen trucks and 80 firefighters were called to the home on Park Lane Circle in the Bayview Avenue and Lawrence Street area just before midnight on Tuesday.
No injuries have been reported.
The high winds made it difficult to control the fire.
The Ontario Fire Marshal will be investigating the cause of the fire.
The damage is estimated to be about $5 million.
