Two Thunder Bay businesses were heavily damaged in separate fires in the early morning hours today.

Several trucks and firefighters responded to a fire at Frankie and Johnny Auto Body on North Vickers Street just before 7 a.m.

Neighbour Albert Busby was there when the fire trucks arrived.

"The smoke was billowing right up," he said. "It was pretty heavy."

The fire service knocked down much of the blaze, but a few trucks and several firefighters remained on the scene to deal with any hot spots.

Busby said Frankie and Johnny Auto Body has been in the neighbourhood for about 40 years. He said he knew one of the owners, and said the man was "devastated."

"[He's] a pretty darn good neighbour," Busby said. "He's been very good, gracious with the neighbourhood."

Fire at Almada Upholstery

A few hours earlier, fire broke out at a May Street upholstery store.

Fire fighters were called at about 3:45 a.m. after a neighbour from behind the single story building saw smoke and flames.

The fire service says the fire at Almada Upholstery took about one and a half hours to put out.

A block of May Street was closed off until about 6 a.m.

No one was in the building at the time it started.

Investigators are looking into the cause of the two fires.
