Stormont Mill on the left of the canal. In the far background is the international bridge. The bridge in the foreground crossed the Cornwall Canal at Augustus Street. Construction of the Cornwall Canal began in March 1834. Over two thousand men, many immigrants Irish Catholics, worked on the project bringing both money and social problems into the small town of Cornwall. The Cornwall Community Museum has a Celtic cross monument to honour early Irish settlers. The population of the Town in 1834 was about one thousand people. In the early 1970s, the canal was filled in and the land is part of Lamoureux Park, today.
