Orion Bus Industries

Orion International was a North American bus manufacturer based in Mississauga, Ontario, Canada. 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 by Arnold Wollschlaeger in 1974 as Ontario Bus and Truck Incorporated, who introduced the Orion bus to market in 1976. The company was renamed Ontario Bus Industries (OBI) in 1977. It expanded operations to the United States in 1981, founding a wholly owned subsidiary named Bus Industries of America. At its peak OBI employed over 1,200 workers in the Mississauga plant.

After falling into arrears on loans provided by the Government of Ontario the government took over operation of the company in 1994. Subsequently it was sold to Western Star Truck Holdings in 1995, which consolidated the names of OBI and its Bus Industries of America subsidiary 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. DaimlerChrysler continued to market its buses under the "Orion" brand name, and Orion Bus Industries was renamed Orion International in 2009.

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