In 1998, we achieved ISO 9000:2000 certification. Callon Dietz is the only cadastral surveying firm in Ontario, and one of the first in Canada, to achieve this internationally recognized designation.

What does this mean for our customers? An Ontario Land Surveyor or a Licensed Professional Engineer directly supervises all work done at Callon Dietz. An Ontario Land Surveyor checks all plans and a regular schedule of field inspections ensures that only the highest quality surveys reach you. We routinely audit all facets of our own practice and hire external auditors to verify our procedures.

In addition to ISO 9000:2000 certification, Callon Dietz is registered with the Ministry of Transportation's Registry, Appraisal, and Qualification System (RAQS). This system registers, prequalifies and tracks consultant performance, determining eligibility to bid for MTO contracts.
