What the record shows
The Province's Protected Countryside boundary sheet 44 lists the City of St Catharines with Pelham, Thorold and Lincoln, and sheet 47 lists it with Thorold; Urban River Valley sheets 49 and 50 cover Twelve Mile Creek in the City of St. Catharines. The Greenbelt Plan's Schedule 1 counts the Protected Countryside, the Urban River Valleys and the Niagara Escarpment Plan Area as parts of the Greenbelt Area.
The Niagara Escarpment Plan's Map 1 covers Niagara Region, and the plan's office consolidation of March 11, 2026 lists the City of St. Catharines among the municipalities with an Urban Area designation, where urban development sits on or next to the Escarpment. The Niagara Escarpment Commission says land in its Area of Development Control may need a Development Permit from the Commission, and its interactive map shows whether a property is in that area. A result from the provincial layers says whether an address falls inside a mapped area and which designation; it is a planning boundary, not a statement about what a particular lot may be used for.
