Stormont—Dundas—South Glengarry

Situated along the north shore of the St. Lawrence River in eastern Ontario, this riding encompasses the city of Cornwall, the United Counties of Stormont, Dundas and Glengarry, and the Akwesasne Mohawk territory straddling the Ontario-Quebec-New York border. From the heritage villages of Morrisburg and Iroquois in the west, through Cornwall's urban core, to the bilingual hamlets of South Glengarry near the Quebec border in the east, the riding covers a broad stretch of the Upper St. Lawrence valley.

Candidates

Guy Lauzon (Conservative) — Born in St. Andrew's West, Lauzon spent more than twenty years in the federal public service, where he served as a local union president of the Public Service Alliance of Canada. After retiring from government in 1993, he became general manager of Tri-County Protein, a soybean processing plant in Winchester. He first won the riding in 2004, defeating longtime Liberal incumbent Bob Kilger, and was seeking his fifth consecutive term. In Parliament he had served as Deputy Government Whip, chair of the Conservative caucus, and parliamentary secretary to the Minister of Agriculture.

Bernadette Clement (Liberal) — Called to the Ontario bar in 1991, Clement moved to Cornwall to work at what became the Roy McMurtry Legal Clinic, eventually becoming its executive director. She was first elected to Cornwall city council in 2006 and was serving her third term as a municipal councillor at the time of the federal campaign. She had also run as the Liberal candidate in the riding in 2011.

Patrick Burger (NDP) — Burger carried the NDP standard in the riding, offering an alternative to the Conservative-Liberal contest that had defined the riding's recent electoral history.

Elaine Kennedy (Green Party) — Kennedy represented the Green Party, focusing on environmental and sustainability issues relevant to the rural and riverside communities of eastern Ontario.

About the Riding

Cornwall, with a population of roughly 46,000, accounts for nearly half the riding's residents and functions as the regional economic hub. Once a major textile and pulp-and-paper centre, the city had shed much of its industrial base by the early 2000s, though a call-centre industry and logistics operations along the Highway 401 corridor provided replacement employment. The Cornwall Community Hospital, opened in 2014, consolidated health care services into a modern facility. Upper Canada Village near Morrisburg draws heritage tourists to its recreation of 1860s rural life along the St. Lawrence, while the Long Sault Parkway offers recreational access to the islands created by the St. Lawrence Seaway flooding of the 1950s. Agriculture—particularly dairy farming—remains important across the rural municipalities. The riding's proximity to the Quebec and U.S. borders has made cross-border trade, tobacco smuggling enforcement, and the economic relationship with Akwesasne persistent federal concerns. Lauzon's deep roots and strong margins in previous elections made the riding difficult terrain for challengers, though Clement's municipal profile gave the Liberals their best showing in the riding in over a decade.
