Leeds South was a federal electoral district in Ontario, Canada, that was represented in the House of Commons of Canada from 1867 to 1904. It was created by the British North America Act of 1867 which divided the County of Leeds into two ridings: a north riding and a south riding. The north riding was combined with the North Riding of the County of Grenville. The riding did not change its boundaries during its existence. It consisted of the Townships of North Crosby, South Crosby, Burgess South, Bastard, Leeds, Lansdowne, Escott and Yonge.[1]
The electoral district was abolished in 1903 when it was merged into Leeds riding.
