The Association of Ontario Land Surveyors (AOLS) was established in 1892. We are a self-governing association, responsible for the licensing and governance of professional land surveyors, in accordance with the Surveyors Act. As with all self-governing professions, the AOLS has a responsibility to ensure that the public interest is paramount. 

Please be advised that we do not provide surveying services or copies of surveys, and neither do we store any files of survey copies in our office. Please refer to our Directory to contact a nearby Professional Surveyor.
