Knowledge Centre

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.

Online Learning Modules

PEO’s Online Learning Modules provide licence holders, volunteers, staff and applicants with various learning and development opportunities.

Practice Advice Resources and Guidelines

PEO offers a variety of practice advice resources to assist licence holders in providing professional and ethical engineering services.

Frequently Asked Questions

The ethics module is not a test and requires no study or preparation before completing it. It is an interactive video refresher to help both practising and non-practising licence holders get reacquainted with their ethical and professional obligations as described in the Professional Engineers Act (PEO’s regulatory role; legal and ethical obligations of licensure; professional misconduct; and a licence holder’s duty to report). You’ll also be reminded on how these obligations should be applied in real-life situations.

All licence holders, including retired P.Engs and those who are not practising, are asked to complete the online ethics module to ensure that they are aware of their ethical obligations and how to govern themselves in compliance with the Professional Engineers Act and its regulation. Licence holders declaring non-practising status must understand what activities are foreclosed to them when they decide to adopt retired status.

The ethics module covers a variety of subjects including: the regulatory role of PEO; what licensure means; a review of legal and ethical obligations of licensure; how to identify and deal with ethical considerations in engineering practice; and professional misconduct.

The ethics module must be completed annually. The content in the module will be changed annually to deal with different issues.

The ethics module should take about 30 minutes to complete.

PEO licence holders, both practising and non-practising, need to complete the online ethics module to become reacquainted with their ethical obligations as described in the Professional Engineers Act and provide them with an understanding of how these obligations should be applied in real-life.

Through completion of the questionnaire, practising licence holders are provided with the recommended number of hours they should commit to continuing knowledge activities. PEO has decided that the maximum recommendation will be 30 hours. This will be reduced based on risk mitigation and quality assurance measures that are part of the licence holder’s practice environment. The tracker provides a dynamic metric of the effect of these measures on the recommended hours.

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 association has been asked on numerous occasions, and for many purposes, if it has reliable data on the number of licence holders practising in specific fields of engineering. Unfortunately, this data is not available.

For the purposes of all regulatory directives regarding engineering practice, 'the public' is considered to be anyone other than the licence holder or his or her employer.
