The cadastre of Québec represents your property on a plan and identifies it by a lot number. This plan shows measures, area, shape and position of the property in regards to neighbouring properties. The cadastre is a registry of the State composed of multiple plans and documents prepared by different land surveyors.
It is possible for a land owner to divide his/her property in order to form other pieces of land that can be sold separately at another time. This process is named « cadastral operation » and is constrained by norms from different laws and by-laws established by municipalities, R.C.M. or even Ministery (ex. Environment).
