Among other things, the purpose of the cadastral renewal is to reconstitute an accurate general picture of all privately owned property in Québec. The renewal process is defined as the action of bringing into line the cadastre, the titles of ownership and the actual occupation of the property. It will correct the 750,000 or so lots for which anomalies have been found, and will also identify the 850,000 immovables (parts of lots) that were not shown on the cadastre in the past, by allocating a separate lot number to each one.

Once the renewal has been completed, there will be only one cadastre, to be known as the Cadastre of Québec. It will be complete, accurate, computerized and updated constantly.
