About United Counties of Stormont, Dundas and Glengarry

The area

The United Counties of Stormont, Dundas and Glengarry (SDG Counties) fill Ontario's southeastern corner, with Quebec to the east and the St. Lawrence River and New York State to the south. Six townships, North and South Dundas, North and South Stormont, and North and South Glengarry, cover about 3,240 km² and had about 66,800 people in 2021. The City of Cornwall (about 47,800) and the Mohawk Nation of Akwesasne are neighbours but separate governments. The townships are rural, with farms and villages inland and St. Lawrence shoreline, beaches and campgrounds in the south; Alexandria in North Glengarry is the main shopping town of the north. Morrisburg in South Dundas is near Upper Canada Village, a living history museum.

History

Cornwall Community Hospital recognizes the area as the traditional lands of the Akwesasne Mohawks. SDG Counties was formally set up in 1850. Early Scottish settlers left their mark in Glengarry, where hamlets such as Dunvegan and Dalkeith take Scottish names, and English and French are both widely spoken there today.

Services and access

Cornwall Community Hospital has a 24-hour emergency department, as do Winchester District Memorial Hospital and Hôpital Glengarry Memorial Hospital in Alexandria. Highways 401 and 417 both lead to Montréal, Highway 417 to Ottawa, and Highway 138 links North Glengarry with Cornwall; North Glengarry is about an hour from both Ottawa and Montréal, whose airports have scheduled flights. VIA Rail stops at Alexandria. North Dundas and North Stormont lean on agriculture, including on-farm businesses.

Land and climate

Rural lots off municipal sewers need a private septic system. In North Dundas, South Dundas, North Stormont and South Stormont, septic permits are issued through South Nation Conservation's septic program under the Ontario Building Code.

Before you buy

Each township's building department issues building permits and keeps its own zoning by-law. SDG Counties maintains the County Official Plan and approves severances and plans of subdivision. Development near watercourses, wetlands and flood- or erosion-prone land needs a permit from the conservation authority for that watershed: the Raisin Region Conservation Authority (about 1,680 km² covering five municipalities) or South Nation Conservation (covering parts of SDG, Prescott-Russell, Leeds-Grenville and Ottawa). Both publish hazard or regulation mapping, and the Raisin Region authority takes property inquiries.
