Resources

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.

Frequently Asked Questions

No, PEO no longer requires Canadian experience. However, any Canadian experience submitted to satisfy the experience requirements must have a P.Eng. validator. This applies to all applicants, regardless of when they applied.

Although it is ideal, validators can be from different places of employment. It should suffice if validators are sufficiently familiar with the candidate’s engineering work experience and can confidently rate the assigned competencies.

Ideally, yes. However, they may be eligible if they can attest to your competencies and are familiar with your work. PEO reserves the right to determine the eligibility of validators.

Yes, validators sufficiently familiar with the candidate’s work and can confidently rate the competencies are eligible.

Validation assists PEO in assessing whether the licensing requirements set out in the Professional Engineers Act and the regulations have been satisfied. Validation does not constitute an assessment of the applicant’s work experience in Canada or internationally—it simply confirms that it was acquired.

A validator assesses and rates the applicant’s work experience. Ideally, a validator should have direct, first-hand knowledge of the applicant’s work, have provided suitable professional supervision throughout the validated work period, and taken technical responsibility for the applicant’s work. The validator may have a title other than supervisor and can be a manager, mentor, client or colleague.

The minimum number of validators required is one. There is no maximum number of validators.

Yes. All applicants must demonstrate the necessary academic and experience requirements before applying. As of July 1, 2026, applicants must have a minimum of 24 months of professional engineering experience, which must be shown when applying through PEO’s competency-based assessment (CBA).
