The Grande Prairie Fire Department continues to investigate a fire that broke out at Motor Tech Services on the City’s north end last night. The building, located on 112 Ave near 99 Street, was fully engulfed in flames as crews arrived at the scene. Crews were unable to enter the building at the time of arrival, due to the significance of the fire and the damage to the roof. The Fire Department responded with two trucks, a ladder and one chief unit. All roads are now fully re-opened to traffic.
