    Land Boundary Change

    Metadata Updated: March 25, 2026

    This layer is derived from the Common Ownership Lots and represents property transactions as they’ve occurred since the implementation of the Vector Property Mapping program in September 2006. A property transaction entails new geometry (split/combination of Lot(s) or property type conversion (from Air Rights, Record, or Tax Lots to Condo lots). The layer contains locations and attributes of archived features (inactive lots – dead lots) and corresponds with Office of Tax and Revenue's Public Extract files (ITSPE). It occurs weekly for the current calendar year and geometry updated when a transaction occurs.
