Welland was originally created in 1867 by the British North America Act. It consisted initially of the Townships of Bertie, Crowland, Humberstone, Stamford, Thorold, and Willoughby, and the Villages of Chippawa, Clifton, Fort Erie, Thorold and Welland. In 1892, the riding was redefined to exclude reference to the Village of Clifton, and include the villages of Niagara Falls and Port Colborne, and the town of Niagara Falls. In 1903, it was redefined to consist of the county of Welland.
In 1952, it was redefined to consist of the townships of Pelham, Thorold, Crowland, Humberstone and Wainfleet, including the city of Welland and the towns of Port Colborne, Thorold, Fonthill and Humberstone.
In 1966, it was redefined to consist of:
In 1976, it was redefined to consist of the City of Welland, the Town of Thorold, and the part of the City of St. Catharines lying south of the Canadian National Railway.
The electoral district was abolished in 1987 when it was redistributed between WellandâÂÂSt. CatharinesâÂÂThorold, St. Catharines and Erie ridings.
A new riding, named Niagara Centre was created in 1996 from parts of Erie and WellandâÂÂSt. CatharinesâÂÂThorold ridings. It existed only for the 1997 and 2000 elections.
It consisted of the Town of Pelham, the City of Welland, the southern part of the City of St. Catharines, and the part of the City of Thorold lying west of the Welland Canal.
The electoral district was abolished in 2003, being split between Niagara WestâÂÂGlanbrook, St. Catharines and Welland ridings. A new Welland riding was created from parts of ErieâÂÂLincoln, Niagara Centre, Niagara Falls and St. Catharines. The Welland riding was abolished in 2013, being largely replaced by a new Niagara Centre riding, losing Wainfleet and the rural southwestern corner of St. Catharines.
Niagara Centre was abolished following the 2022 Canadian federal electoral redistribution, and was replaced by Niagara South. It gained Fort Erie from Niagara Falls, and lost all of its territory in the City of St. Catharines to Niagara West and St. Catharines. These changes came into effect following the call of the 2025 Canadian federal election.
