Newtonville is a community located in the Municipality of Clarington, Ontario, Canada. It is located about 30 kilometres (19 mi) east of Oshawa and about 10 kilometres (6.2 mi) west of Port Hope on the former Highway 2.
Newtonville is the most easterly community in Clarington (and in Durham Region), and therefore forms the eastern end of the Greater Toronto Area. The community was formerly part of the southeastern part of the township of Clarke until 1973.
Post office history
Newtonville's first Post office opened in 1835 when the village was known as both "Clarke" (named after Clarke Township, which it was part of) and "Newton". It was located at the corner of Kingston Rd. (Highway 2) and the 8th Sideroad. The first Postmaster was Thomas Hymers, and the first mail carrier was John Carscadden, who carried mail from here to Kendal in 1857. The village had eight Postmasters since the inception of the Post office. The last Postmistress was Joyce Carroll in 1991. At this time Canada Post's mandate was to close many of the smaller rural Post offices. Since then the village has been placed on a Rural Route delivery sorted in Port Hope. A retail postal outlet exists today at the store in the centre of Newtonville. The store was damaged by fire in 2008 and has since been rebuilt.
