No one was injured in the fire, which completely destroyed one pumper truck and significantly damaged a tanker truck, Grimwood said.

"As much as we've destroyed two trucks here, this is a big victory," he said. "This was an incredibly large fire."

Grimwood estimated the loss of the two vehicles at more than $500,000.

Winds shifted quickly and the trucks were set ablaze while they were being repositioned, Grimwood said.

This was the first time a fire truck had been destroyed during a blaze in Haldimand County, he added.

Shelton Volunteer firefighter Mark Lovelace was driving the truck at the time of the crash. He and volunteer firefighter Jason Ruyle were transported to CHI Health Good Samaritan where they were treated for injuries and released.

Deputies estimated damage to the grain bin at $20,000, while the truck was estimated to be a total loss.

Two people extracted from the car were taken to a local hospital, Southern said. Their conditions were not known.
