This opinion often takes the form of a plan, report, and property corner markers, and is based on an analysis of documentary research and field measurements. The public widely recognizes this professional service as it is commonly used to facilitate the purchase and financing of residential and commercial real estate.

Only licensed members of the Association of Ontario Land Surveyors can carry out cadastral surveys in the Province of Ontario.
