Whitby—Oshawa was a federal electoral district in Ontario, Canada, represented in the House of Commons of Canada from 2004 to 2012. Following the 2012 federal electoral boundaries redistribution, the bulk of the district became part of the new Whitby district, while parts were transferred to Oshawa and Durham.
The riding was created in 2003 and consists of 68 percent of the Whitby—Ajax district, 20 percent of the Oshawa district and three percent of the Durham district.[1] The provincial electoral district was created from the same ridings in 2007.
