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.

Yes. Technical exams are written online. Candidates may write technical exams outside of Canada, as long as they have high-speed internet and a webcam.

No, you cannot declare the completion of the professional practice module as a CPD activity because the module is a separate mandatory element of the PEAK program.

If you also complete CPD activities for another regulator or your employer, you can add those activities to your CPD Report if they meet PEO’s CPD admissibility criteria.

No, the program will not allow you to complete CPD activities this year and carry forward any portion to a future year. That’s because you will be engaging in CPD every year on a continuous basis.

Possibly; the program will allow you to report CPD activities you completed last year only if you still have a CPD reporting balance for last year. Once you have met last year’s CPD requirements and have no overdue balance for last year, you will not be able to report more CPD activities from last year.
