PEO publishes a variety of resources to assist licence holders in their roles and responsibilities, as well as guidance for applicants going through the licensure process.


Ontario professional engineers are part of a community of more than 87,500 PEO licence and certificate holders committed to enhancing the quality of life, safety and well-being in the province.

PEO’s Engineering Intern (EIT) program provides guidance and assistance to engineering graduates as they acquire the 48 months of acceptable engineering work experience, including annual reviews of experience.

As the regulator of engineering in Ontario, it’s PEO’s role to assure the public that licensed practitioners are competent to practise in their chosen discipline, and that they are taking responsibility for the outcomes of their work.

As Ontario’s engineering regulator, PEO relies heavily on its volunteers. More than 1,000 professional engineers, engineering interns and non-engineers volunteer their time each year on behalf of the association through their participation.

PEO's mandate, as described in the Professional Engineers Act, is to ensure that the public is protected and that individuals and companies providing engineering services uphold a strict code of professional ethics and conduct.

Frequently Asked Questions

Though PEO has tried to anticipate the potential answers to every question, it is quite possible that for some questions, no answer directly pertains to a licence holder’s current situation. If so, please choose the answer that is nearest to the answer you would prefer. If none is acceptable, choose the first answer (lowest risk). If you can, please notify PEO at providing the question and your preferred answer.

PEO is collecting this information in order to obtain a clear picture of what its licence holders are doing.

The questionnaire is designed to ensure that PEO has sufficient and necessary information on its licence holders to effectively carry out its role as the regulator of the profession.

PEO does not anticipate that a fee increase would be required to implement the present version of the PEAK program.
