Stormont—Dundas—South Glengarry

Stormont—Dundas—South Glengarry sits in the southeastern corner of Ontario, stretching along the north shore of the St. Lawrence River from the Quebec border westward through the United Counties of Stormont, Dundas, and Glengarry. The riding encompasses the City of Cornwall—its principal urban centre—along with the townships of South Glengarry, North Stormont, South Stormont, North Dundas, and South Dundas. The Ontario portion of the Akwesasne Mohawk Territory, which straddles the Canada–United States border at the confluence of the St. Lawrence and St. Regis rivers, also falls within the riding's boundaries. The riding covers a mix of riverfront towns, agricultural land, and small villages.

The population was approximately 110,000 as of the 2021 census. Cornwall accounts for roughly half of the riding's population. English is the dominant language, though the riding has a historically significant francophone minority—approximately 17 percent of residents report French as their mother tongue, reflecting the area's position near the Quebec border. The riding is predominantly rural outside of Cornwall.

Candidates

Eric Duncan (Conservative) — Born in 1987, Duncan was elected to North Dundas municipal council at age eighteen and became mayor four years later at age twenty-two—one of the youngest mayors in Ontario. He was acclaimed for a second mayoral term in 2014 and became the youngest regional Warden in the 170-year history of the United Counties of Stormont, Dundas, and Glengarry at age twenty-five, subsequently becoming the first to serve consecutive years as Warden. He attended North Dundas District High School in Chesterville and is the first openly gay Conservative member of Parliament.

Denis Moquin (Liberal) — Moquin spent forty-five years in policing, security, and investigations, including a career with the Cornwall Police Service from 1976 to 2001 where he retired as a sergeant. He later served as Executive Director of Community Agencies of Stormont, Dundas, and Glengarry and as a Cornwall City Councillor from 2003 to 2006.

Trevor Kennedy (NDP) — Kennedy is a construction worker from Ottawa who grew up on his family's farm and understands the challenges facing rural communities. The NDP riding association noted that they had attempted to select a local candidate but were unable to complete the process before the Elections Canada deadline.

David Anber (PPC) — Anber was the People's Party of Canada candidate in the riding, running on the party's platform of fiscal responsibility and reduced government intervention.

About the Riding

Cornwall has undergone a significant economic transition over the past several decades. Once an industrial centre anchored by textile mills and manufacturing plants, the city has diversified into logistics, food processing, call centres, and technology. The riding's strategic location—sitting on the Highway 401 corridor with proximity to Montreal, Ottawa, and the United States border—has made distribution and warehousing a growing sector. The St. Lawrence Seaway, which passes through the riding, remains a vital piece of transportation infrastructure linking the Great Lakes to the Atlantic Ocean.

The riding's francophone community, concentrated in Cornwall and the Glengarry townships, maintains a vibrant cultural presence through schools, churches, and community organizations. The area's Scottish heritage is also deeply rooted—the Glengarry Highland Games in Maxville have been held annually since 1948 and draw thousands of competitors and spectators from across North America. Lancaster, Williamstown, and the surrounding South Glengarry townships retain strong connections to their Loyalist and Scottish settler origins.

The presence of the Akwesasne Mohawk Territory introduces cross-border governance and Indigenous policy into the riding's political landscape. Cornwall's location on the international border has also made border security and customs enforcement recurring topics. Healthcare access, rural broadband connectivity, and support for agricultural operations are persistent concerns across the riding's vast rural territory.
