Unlicensed People Offering Surveying Services

One of the responsibilities of the AOLS is to protect the public from unlicensed practitioners offering to provide cadastral surveying services. If you are suspicious of a person who claims to be a surveyor, offering to establish legal boundaries (including the marking of your property for fencing purposes) or prepare survey plans, ask for identification. If the person cannot prove that they are a member of the Association of Ontario Land Surveyors, or are working for a member, please note the name of the person and contact the Registrar at the Association office.

Unlicensed practitioners do not carry liability insurance and may leave you subject to serious financial liabilities.

By law, only licensed members of the Association of Ontario Land Surveyors can carry out cadastral surveys in the Province of Ontario. Under the Surveyors Act:

11 (1)  No individual shall engage in the practice of cadastral surveying or hold himself or herself out as engaging in such a practice unless he or she holds a licence under this Act.  2009, c. 33, Sched. 22, s. 11 (14).

Practice of cadastral surveying” means advising on, reporting on, conducting or supervising the conducting of surveys to establish, locate, define or describe lines, boundaries or corners of parcels of land or land covered with water; (“exercice de la profession d’arpenteur cadastral”)
