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 questionnaire is intended to capture information regarding your current status so describe the practice environment for your current employment situation.

The last 12 months.

Choose the answer that poses the greatest risk. For all questions, the lowest risk is the first answer and the greatest risk is the last answer.

It should take about 15-20 minutes to complete.

The questionnaire has 20 questions.

Existing information on PEO licence holders, such as current employer and contact information, is significantly flawed and incomplete. To correct this, and to obtain additional data needed for policy development purposes, all licence holders are asked to verify their personal information in the Member Portal. 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. 

There is no cost for completing the PEAK program on-line documentation or the on-line ethics module. Cost of the continuing knowledge activities undertaken by individual licence holders depends on the type of activity chosen. PEO does not provide any continuing education course nor make any recommendations concerning the knowledge activities suitable for individual licence holders. Choosing these activities and the associated costs is the responsibility of the licence holders or their employers.

While completion of the PEAK program is not mandatory, should a licence holder refuse to complete any element of the program in the allotted time, this information will be publicly noted on PEO’s online directory of practitioners.

A person is considered to be practising professional engineering if he or she is carrying out any act of designing, composing, evaluating, advising, reporting, directing or supervising, or the managing of any of these acts and those acts:

  1. involve the safeguarding of life, health, property, economic interests, the public welfare or the environment, and
  2. require the application of engineering principles.

The definition applies to all situations where this particular combination of intellectual activity, societal protection and methodology exists regardless of whether the position is in industry, government or consulting. A person does not have to be employed in a firm holding a Certificate of Authorization in order to be classified as practising. Nor does a person have to seal engineering documents.

A person is considered non-practising if he or she is licensed by Professional Engineers Ontario but is retired, unemployed, on leave, or employed in a position that does not involve carrying out any of the acts described in the “practising” definition. When on fee remission, a person cannot engage in any practice activity for any purpose whether paid or unpaid. Others who self-identified as non-practising retain full right of practice and can engage in any practice actively as long as it is done in full compliance with the Professional Engineers Act and its regulations.
