All properties in Ontario carry another identification and numbering system dating back to the time of the first land settlers. Land was then divided into lots, concessions, townships, and more recently into subdivision plans, condominium plans, etc. as well as into Towns/Cities/Regions to enable us to describe each and every property. This underlying fabric is the base for the legal descriptions we rely on for all land transactions and government authorities' use. Note that the underlying lot fabric on the face of the plan must match the Title Block.
