More changes at Decoma Autosystems in Belleville. Magna spokesperson Tracy Fuerst says they’ll be closing one of their plants in the Northeast Industrial Park and consolidating production lines in the other two plants. The downturn in the North American auto industry is partly to blame. About thirty people also received permanent layoff notices this morning. There are currently about 700 people working for Autosystems in Belleville….making headlamps for a variety manufacturers including the “big three automakers”.
