Woodbine Entertainment reported Monday that 32 Thoroughbreds were killed in Sunday’s barn fire at Woodbine Racecourse near Toronto, Ontario. The damage estimate was set at $3 million.

The horses were stabled in barns 7 and 7A at Woodbine. The fire was spotted at 2:50 a.m. EDT in barn 7 and, fueled by hay and wooden beams, quickly spread to barn 7A.

No humans were killed or seriously injured, though some suffered from smoke inhalation. The barns were nearly at capacity–126 of the 128 stalls were filled–and a groom who was sleeping in the barn at the time is credited with getting at least 50 horses out of their stalls. He received help from other grooms and security personnel.

“Our security people were here within a minute,” said David Willmot, chairman and chief executive officer of Woodbine Entertainment. “And people came flooding out of the barns to help. It’s unbelievable how many horses were saved
