All surveyors who provide surveys to the public must maintain Professional Liability insurance. This ensures that any person who suffers a loss because of an error or omission is protected. The AOLS voluntarily embraced the mandatory requirement for insurance in 1980, while virtually all other professional groups waited until mandatory insurance was legislated upon them.

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

The Surveyors Act has the following provision:

32.

  1.  No member of the Association or holder of a certificate of authorization shall engage in the practice of professional surveying unless insured against professional liability in accordance with the regulations or in accordance with arrangements under subsection
     
  2.  R.S.O. 1990, c. S.29, s. 32 (1); 2009, c. 33, Sched. 22, s. 11 (46).
     

Ontario Regulation 1026 contains the following provisions:
