Stormont-Dundas-South Glengarry is the southeast most riding in Ontario with its eastern border touching the provincial border with Quebec. The southern border follows the St. Lawrence River. The western border abuts the riding of Leeds-Grenville with the northern border touches both Carleton and Glengarry-Prescott-Russell. The riding includes the city of Cornwall and the Mohawk Nation at Akwesasne.
The riding was created in 2003 with a majority of it coming from the previous Stormont-Dundas-Charlottenburgh. Before this change the seat was primarily held by the Liberals but since 2003 Conservative MP Guy Lauzon has been the representative.
Dundas was one of the first ridings introduced with the British North America Act but has since gone through several restructurings due to the increase in population density.
