In 1882, the East Riding of the county of Elgin was defined as consisting of the townships of Yarmouth, Malahide and Bayham, the villages of Port Stanley, Aylmer and Vienna, and the city of St. Thomas.
In 1903, the riding was redefined to exclude the township of Malahide and the city of St. Thomas, and to include the townships of Dorchester South and Malahide, and the village of Springfield.
The electoral district was abolished in 1924 when it was redistributed between Elgin West and Elgin—Norfolk ridings.
