The original Brock Township was surveyed in 1817 as part of
York County and the first meetings were held in 1833. The township was named for
Major General Sir Isaac Brock (1769–1812) whose estate received free land here for his service in the
War of 1812. William Bagshaw became Brock's first Postmaster and Justice of the Peace in 1819 when he owned property on Concession 9. Other early, settler ancestors included names like: Acton, Charters, Dusto, Purvis, Rundle, Bagshaw, Doble, Phair, St. John, Umphrey, Brethour, Doyle, Fallowdown, Ruddy and Vrooman (for whom the semi-
ghost town of
Vroomanton was named). In 1852, the Township became part of the newly created
Ontario County. In 1878,
Cannington was incorporated as a village and was no longer part of the Township for municipal purposes. In 1974, Brock was amalgamated with
Thorah Township and the villages of
Beaverton and
Cannington to form the new Township of Brock. ==Communities==
