Corunna, Ontario: History, Things to Do and Travel Guide
Corunna is a St. Clair Township community on the St. Clair River in Ontario’s Southwest Ontario region. Its wide main streets and river setting come from one of Ontario’s more unusual town plans: an 1823 survey for a proposed capital.
For travellers, Corunna is a riverfront stop with ship-watching, trail access, local services and a direct line into the history of the former Moore Township. It is compact, residential and shaped by the St. Clair River more than by a large downtown attraction district.
How Corunna Started
Moore Museum’s Corunna history explains that Lord Beresford surveyed the site in 1823 while looking for a capital for a proposed united Upper and Lower Canada. The plan included a 10-acre St. George’s Square for government buildings and streets laid out to echo the Union Jack.
The capital plan was abandoned because the site was considered too close to the United States after the War of 1812. The survey still left a physical mark. Lyndoch Street and Hill Street kept the broad widths planned for the main roads of the proposed capital, and several street names reflect Beresford and his fellow officers.
Settlement came slowly at first. Lots were put up for sale in 1837, and Corunna developed around river traffic, hotels and docks that handled timber, grain and potash. Moore Museum notes that the village remained one of the less-settled places along the St. Clair River until after the Second World War, when employment in the Sarnia-Lambton industrial corridor brought new growth.

Travel Notes
Corunna is easiest by car, though the waterfront trail makes cycling part of the visit for prepared riders. Trail users should check current conditions, respect posted rules and expect a mix of road and path sections.
Spring through fall is best for walking, cycling and riverfront stops. Winter visits are quieter and more practical if the goal is local history, food or a short shoreline drive.
The river is an active shipping corridor. Treat the shoreline as a viewing place, not a swimming or paddling plan unless you have current local safety information and suitable experience.
