Your house address is a method of describing the location of your property devised by your municipality. It is quite different from the legal description of your property that is used at land titles. For land that is located in a city, town, village or acreage, the legal description is set by Plan number; Block number; and Lot number. Municipalities approve plans for the subdivision of land within their jurisdiction. This subdivision plan is reviewed by Land Titles and assigned a Plan number. Last updated: October 2015
