Windsor fire crews had to battle a fire in a commercial building on the city's near east side Monday morning.
Crews were called to Wyandotte and Marion about 4:15 am, and arrived to find a working fire in a restaurant.
At least one neighbouring house had to be evacuated as crews battled the blaze.
Officials say the fire started inside the Original Pizza Brothers restaurant.
An early damage estimate is pegged at $600,000 but that could escalate.
No one was injured.
There is no word on a cause of the fire as of yet.
