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.


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

Frequently Asked Questions

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.

Anyone who illegally uses an engineering seal may be found guilty of an offence under Section 40 of the Act and may be fined up to a maximum of $10,000 for a first offence, and $25,000 for any subsequent offence. Police may also lay fraud or forgery charges. These offences are usually carried out by non-engineers without the knowledge or consent of the engineer in question. This is why engineers should store their seal in a secure place.

The seal is the property of Professional Engineers Ontario and must be returned when one leaves the association.

According to lawyer William Black of McCarthy Tetrault, the "signing or sealing of documents by engineers ... has absolutely nothing to do with the question of liability for negligence. Engineers are liable because they prepared the drawings or because they supervised or approved them, and not because they signed or sealed them." Nevertheless, the seal is important because it implies a commitment to the standards of the profession and signifies to the public that a particular P.Eng. has accepted professional responsibility for the document. Should any errors be found, the engineer who seals the document is answerable to PEO, their client and any agency relying on them.

PEO policy on matters related to electronic documents is provided in the Guideline for the Use of a Professional Engineer’s Seal. Professional engineers are allowed to scan or otherwise create electronic facsimiles of their seals and signatures and apply these to electronic documents. Professional engineers who do so should consider use of appropriate security measures, since an electronic drawing with a seal and signature could be changed without the engineer's knowledge and a third party would still expect that the engineer is responsible for the entire content of the document.

Known as " as-built drawings," these should not be sealed. Seals should be applied only in those cases where you or your delegate have visited the site, reviewed the project during construction, and have verified every change in detail. The changes must be clearly marked on the drawings and a note referencing the original sealed drawings should be attached. These documents are referred to as “record drawings” to distinguish them from “as-built drawings”. Record drawings verified in detail by the engineer and issued to a third party must be sealed.

The engineer's signature and the date the document was sealed, hand written within or beside the stamp, must always be included. Initials alone are not acceptable.

No. PEO members are not permitted to use, or refer to, their professional seals in company logos, advertising or other promotional materials.

Certain types of legal documents are required to be sealed. However, the professional engineer's seal is not appropriate for these purposes. Contracts and other legal business documents are sealed with a corporate seal if the business entity is a corporation. If not, signatures suffice. Professional seals are not to be used for this purpose. Certain documents, such as statutory declarations, must be sealed by a Commissioner for taking affidavits or a Notary Public in order to be valid. A Commissioner for taking affidavits is a person, such as a lawyer, MPP, municipal official or court official who is authorized to administer oaths or take affidavits. Notaries public are regulated by the Notaries Act. Persons, other than barristers and solicitors, wishing to be appointed as notaries must have their qualifications examined by a Superior Court judge. Only persons certified by a judge will be considered for the position and, if selected, are appointed by the Attorney General. Passport applications, birth certificate applications and other documents that identify professional engineers as suitable guarantors require only the guarantor's signature followed by the "P.Eng." designation.
