Sunderland is a community located approximately 100 km (62 mi) northeast of Toronto, Ontario, Canada in Brock Township, in the Regional Municipality of Durham.

Sunderland slowly grew around the Brock Hotel - a popular overnight stop for travellers that was owned by Lorenzo Jones.

The first post office was called Brock and was run by Andrew Hill; it was located just north at the modern junction of Highway 12 and 7th Concession.

He was the Secretary of State, and he helped move Palatine German families to London and then, with Queen Anne's aid, to Ireland in the early 18th century.

These early Palatine settlers included surnames like: Shier, Baker, Bagshaw, Switzer, Lowe, St. John, Lodwick, Brethour and Doble.

Although the railway ceased operations through Sunderland in the 1980s, the town has remained vibrant, due in no small part to its close proximity to Toronto, Lindsay, and Newmarket.

27 River Street is the home of Thomas Welsh (1856-1925), a local entrepreneur who ran a grist mill at the location of the current Sunderland Co-Operative and in the evening provided electricity to the town around 1916.

160 River Street, a large brick home, was originally owned by Dr. James McDermott, a medical doctor and resident from 1870 -1920.

He organized the rebuilding of the Brock House in 1910 and financed the building of the McDermott Block, a multi-unit commercial structure at the south east corner of River and Albert streets.

28 Jones Street was acquired by Charles Leslie Lowes, a self-made millionaire who apprenticed in Sunderland as a baker under the tutelage of William Thompson.

The club runs various fundraisers throughout the year such as a car draw and beach volleyball tournament as well as annually hosting a Blue Rodeo concert.

One of the club's largest service projects is the annual Sunderland Lions Music Festival which is held over three weeks, beginning in mid-April.

There are about 30 homes on the extreme south-west corner of Brock Township with (rural route) Sunderland mailing addresses and a 905 North American area code.
