Cornwall

Community

Cornwall, incorporated in 1945, is located on the banks of the St. Lawrence River, close to Ottawa and Montreal. It is in the traditional territory of the Audenosaunee (Iroquois), Mohawk, Haudenosaunee (St Lawrence Iroquois), and Huron-Wendat. Originally called New Johnstown, it was renamed Cornwall as an honour for the Prince of Wales (Duke of Cornwall). It is one of Canada’s oldest communities, first settled in 1784 by United Empire Loyalists. It became an important industrial centre in Eastern Ontario in the late-19th century, featuring flour, paper, and textile mills. Thus, Cornwall became an important transhipment point until the completion of the St. Lawrence Canals and Grand Trunk Railway in the mid-1850s. Cornwall harbours multiple historic sites, including St. Raphael’s Ruins, the Historic Jail, and natural beauties such as Gray’s Creek Conservation Area, Guindon Park, Lamoureux Park, and the extensive Waterfront Trail.
