These people hold the exclusive title of Canada Lands Surveyors (CLS). Surveyors are the experts in the science of measurement and positioning and use these skills to accurately measure the true dimensions of property. This expertise is used to prepare plot plans, real property reports, place boundary markers, and other activities ensuring the accuracy of public property records. Of all the Canadian surveyors associations, the ACLS has the largest jurisdiction, in terms of geographic size; it covers a territory of approximately 10,900,000 square kilometres, which is about seven times the surface area of the Province of Quebec.
