Where Centennial sits
Centennial covers the north-west quarter of established Oshawa: Rossland Road West on the south, Taunton Road West on the north, Simcoe Street North on the east and Stevenson Road North on the west, with the main branch of the Oshawa Creek cutting a wooded valley through its eastern half. Nonquon Road and Beatrice Street West are the local connectors between the arterials. Some maps push the western edge out to Thornton Road North, taking in streets that other guides call Northglen, so treat that line as approximate.
