About Cornwall
Cornwall is a city in Eastern Ontario located on the north shore of the St. Lawrence River near the Quebec border, with a population of approximately 47,000 residents. As the easternmost major city in Ontario, Cornwall sits at the convergence of Ontario, Quebec, and New York State, making it a strategic border location. The city is known for its bilingual character, reflecting its proximity to Quebec and its Franco-Ontarian heritage.
The city's economy is diverse, with strengths in manufacturing, healthcare, call centers, and retail. Cornwall is home to the Cornwall Community Hospital, St. Lawrence College, and serves as a regional shopping and service center for Eastern Ontario and Western Quebec. The scenic St. Lawrence River waterfront features parks, trails, and recreational facilities including the Cornwall Civic Complex. The city's rich history includes its role in the War of 1812 and its development as an industrial center along the St. Lawrence Seaway.
Highway 401 runs just north of Cornwall, providing connections to Montreal (80 km east) and Ottawa (110 km northwest). Highway 138 connects Cornwall to Quebec across the Seaway International Bridge. Pitt Street serves as the main downtown corridor, while Brookdale Avenue and McConnell Avenue are major commercial routes. The St. Lawrence River defines the city's southern boundary, and the nearby Long Sault Parkway offers scenic island-hopping access to parks and beaches. Cornwall's location on the Seaway makes it an important shipping and transportation corridor.
