KITCHENER -- Waterloo regional police say they're currently at the scene of "multiple vehicles on fire" at King Street East and Borden Avenue North in Kitchener.
Police tweeted about the fire around 4:15 p.m. Wednesday.
"There was about a 10-foot flame off the top of that building," witness Patrick McDonald said.
Fire crews could be seen battling the blaze at Yilmaz Auto Repair.
Fire crews at the scene said they believe the fire started while staff were working on a vehicle.
Crews were called around 3:45 p.m. At the height of the fire, more than 20 firefighters from four different stations were working to get the flames under control.
"The structure was wood, both the floor and ceiling and with rapid fire progression through the building, we felt it was safe to stay exterior," Assistant Platoon Chief Carlin Riley said.
No one was injured in the fire. Workers in the adjacent shop alerted the rest of the employees and the building was evacuated.
"It may have been started in a battery in an e-bike," Riley said. The Ontario Fire Marshal's Office has been contacted.
On Thursday, police said that the fire was believed to have been accidental.
There's no official estimate on the cost of the damage, but CTV News was told the building is worth around $2 million. Police said that there was an estimated $250,000 in damage.
