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.

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.

Yes. Council’s CPD task forces recommended the PEAK tenets and operating rules after reviewing other regulators’ CPD reporting programs and best practices to establish a made-for-PEO program that would be straightforward and less cumbersome for PEO licence holders. PEO licence holders were also surveyed for their feedback before the task forces made their recommendations.

Note: Council’s CPD task forces worked from 2015 to 2017 and included engineers representing a range of demographics (a council member, academic engineer, in-house engineer, non-practising engineer, government engineer, manufacturing engineer, sole practitioner, retired engineer, and an engineer at a consulting practice.) And in 2022, a consultation survey was carried out to inform the transition to a mandatory version of the PEAK program.

Unlike other regulators, the Practice Review in Ontario is a voluntary (optional) initiative to ensure the acceptable manner of operating and managing a professional engineering practice.

The Practice Evaluation questionnaire is presented to licence holders who are currently practising or intend to practise later in the year. The questionnaire was created by PEO alongside Council’s CPD task forces. The task forces comprised engineers representing a range of demographics(a council member, academic engineer, in-house engineer, non-practising engineer, government engineer, manufacturing engineer, sole practitioner, retired engineer, and engineer at a consulting practice.) The wording of the questionnaire was refined in 2022 and PEO will continue to review and revise it, as required.

Note: It is possible that some individuals could find the questions irrelevant to them, indicating that perhaps they should select the non-practising status.

A Practice Review is a review of a workplace providing professional engineering services to assess whether the processes and procedures for carrying out professional engineering activities are consistent with the profession's standards. Generally, the essential purpose of a practice review is to assess the fundamental policies and procedures in place for how the practice of engineering is conducted. These reviews intend to provide an opinion on the compliance of non-technical practices with the Professional Engineers Act and industry best practices for operation and management.

Yes. The PEAK program applies to all licence holders regardless of their practice status. However, licence holders who work in a practice area where the “industrial exception” may apply should be careful about selecting a “not practising” status for several reasons: the industrial exception is narrow in its application; the industrial exception only relates to the need for a PEO licence, not to the determination of practice status; and they would still be practising even if they are “not stamping” or “not providing engineering services to the public.”

Yes, PEO provides guidance for how these reviews can be carried out fairly, consistently, thoroughly and in a manner that complies with the purpose of the review. The primary purpose of the Conducting a Practice Review guideline is to define the content of practice reviews so reviews can be conducted consistently.
