The City of Cornwall uses a process called zoning to control the use of land in the City. The comprehensive zoning by-law divides the municipality into different land use zones and specifies the permitted uses and required standards in each zone.

The zoning by-law determines how land may be used, where buildings and other structures may be located, the types of buildings permitted and how they may be used, as well as lot sizes and dimensions, parking requirements, building heights and setbacks from the street.
