What is PEO?

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

Established on June 14, 1922, PEO licenses and disciplines engineers and companies providing engineering services in Ontario. Its principal object is to regulate the practice of professional engineering and govern its members to serve and protect the public interest by ensuring all professional engineers meet 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 ensures licence holders’ engineering practices are technically competent, based on sound professional ethics and adhere to standards of practice that are the hallmark of professional engineering. Engineering graduates who become professional engineers (P.Eng.), indicate to their clients, co-workers, the public and others that they are committed to safeguarding the public. 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.
