What is PEO?

Through the Professional Engineers Act, Professional Engineers Ontario governs licence and certificate holders and regulates professional engineering in Ontario to serve and protect the public.

Established on June 14, 1922, Professional Engineers Ontario (PEO) is the licensing and regulating body for engineering in the province. It fulfills the same role for engineers as the College of Physicians and Surgeons for doctors or the Law Society of Upper Canada for lawyers.

Under the Professional Engineers Act, a provincial statute, PEO is responsible for the licensing and discipline of engineers and companies providing engineering services. PEO is committed to ensuring a high standard of fairness and innovation in all its operational processes and strategic activities. The principal object of the association is to regulate the practice of professional engineering and to govern its members in order that the public interest is served and protected. It protects the public by ensuring all professional engineers have met the rigorous qualifications for licensing and that only properly qualified individuals practise engineering. As part of its mandate, PEO also establishes, maintains and develops:

  • standards of knowledge and skill;
  • standards of practice for the profession;
  • standards of professional ethics; and
  • promotes public awareness of its role.

PEO's licensure process demands an extra measure of competence and dedication. Becoming licensed indicates that the practitioner appreciates the importance of work that is not only technically competent, but also based on sound professional ethics and that adheres to the standards of practice that are the hallmark of professional engineering. Engineering graduates who become professional engineers (P.Eng.), indicate to their clients, their co-workers, the public and others, that they are committed to safeguarding the public welfare. PEO licence holders work to guarantee the public's safety and promote its interest where engineering matters are concerned. They also must ensure that provincial laws adequately and properly serve and protect the public, and participate in the establishment and maintenance of engineering standards while adhering to a Code of Ethics.

Individuals may only call themselves a professional engineer, or a P.Eng., or use a similar title that may lead to the belief that they are qualified to practise professional engineering, if they are licensed by PEO. People or companies may only offer or provide engineering services to the public if they hold a Certificate of Authorization from PEO.
