Orion Bus Industries

Orion International was a North American bus manufacturer based in Mississauga, Ontario, Canada operated a subsidiary of Daimler Buses North America, a division of German automaker Daimler AG. The company had its main manufacturing plant in Mississauga and sent bus body shells to their plant in Oriskany, New York, for final assembly and testing of vehicles destined for U.S. markets.

The company was founded in 1974 as Ontario Bus and Truck Incorporated by Arnold Wollschlaeger who then introduced the Orion, which then renamed the company to Ontario Bus Industries in 1977. It then expanded to the United States in 1981 upon the founding of Bus Industries of America. At its peak OBI employed over 1,200 workers in the Mississauga plant.

After years of debt, it was later taken over by the Ontario Government in 1994 for loan arrears and was sold in 1995 to Western Star Truck Holdings which then renamed both entities to Orion Bus Industries. In 2000, Western Star was purchased by a division of DaimlerChrysler, and in 2006, Orion was absorbed into DaimlerChrysler Commercial Buses North America. For some period of time thereafter, DaimlerChrysler continued to market its buses under the "Orion" brand name; even though Orion Bus Industries was renamed to Orion International in 2009.

In April 2012, Daimler announced the closure of Orion with bus production halted in 2013.
