The 1991 Orion V models were a little different than the 1990 models. These buses came with a/c, the unit was located where the rear window was on the 1990 model. When these buses arrived on the property, there was a serious shortage of buses due to the GMC New Look's being retired. Many buses never received decals until mid 1992, due to this, there were many complaints by residents finding it hard to see the all white buses in the winter, being so used to the former all orange buses. Buses then recieved the 1992 City of Sudbury colours. All buses received the City of Greater Sudbury colors after 2001. All buses in this series were retired in late 2009.
