Part of Lots
In addition to street addresses, all Ontario properties are identified with a ""legal"" numbering system, which surveyors call ""underlying lot fabric"", to describe the property's physical geographical location. ""Underlying lot fabric"" is listed in the title block summary legal description and integrated visually on the survey plan in phantom/dashed lettering. The plan further depicts all legal information of adjoining properties including their ""underlying lot fabric"", PIN Numbers and easements (if any) to provide a solid legal frame of reference for the plan of survey. Dating back to the time of the first land settlers, land, as officially recorded in land registry offices, was originally divided into lots, concessions, townships and then subsequently into registered plans, subdivision plans and condominium plans within Towns/Cities/Regions. These ""legal"" descriptions of properties are an integral part of various legal documents for land transactions and mortgages recorded in the land registry offices, as well by municipal and provincial governmental authorities for tax assessments.
The property's legal description provides a formal frame of reference for geographic location of property and is the formal identifier for the surveyed land.
Why is this important?
This provides key information about your property. Land professionals (land surveyors, lawyers, planners etc.) are obliged to use this identification system in their legal documents when dealing with land and boundary issues . Street addresses are secondary.
