Being a professional enginer tells employers that you’re committed to engineering excellence; have the right skills, education, and attitude; and are a responsible professional with the proven problem-solving abilities to help their business build business.

To become a professional engineer (P.Eng.) in Ontario, you must be licensed by Professional Engineers Ontario (PEO).

From past to future

For more than 90 years, PEO has governed its licence and certificate holders and regulated professional engineering practice to serve and protect the public of the province. Under the Professional Engineers Act, PEO establishes the educational, experience and other requirements for licensing, and disciplines licence and certificate holders who fail to maintain the expected standards of practice.

PEO also raises public awareness of its role and of engineering as a licensed profession. Only a PEO licence holder can take responsibility for professional engineering work in Ontario; only a PEO Certificate of Authorization holder can offer or provide engineering services to the public.

Recent PEO initiatives have made it easier for applicants from outside Canada to apply for and become licenced. The Professional Engineers Act no longer requires that an applicant be a Canadian citizen or landed immigrant to become licensed. PEO research had shown that a misunderstanding of the residency requirement was the primary reason for newcomers waiting to apply for a licence.

“Since 1922, the Professional Engineers Act has set the bar for practice in a profession in which public safety—in its broadest sense—is paramount.”

With the elimination of the residency requirement, many qualified applicants can now arrive in Canada having met most of the licensing requirements and be ready immediately to enter the engineering workforce.


In addition, engineering graduates, newcomers to Canada, and unlicensed people working in industry may be eligible to have their Ontario licence application fee waived under the association’s Financial Credit Program. Eliminating this potential financial hurdle ensures that everyone with appropriate qualifications has an equal opportunity to apply for a P.Eng. licence.

Since 1922, the Professional Engineers Act has set the bar for practice in a profession in which public safety—in its broadest sense—is paramount. PEO protects and serves the public by ensuring all PEO licence holders are qualified—and by licensing all who qualify—as well as by holding licence holders professionally accountable for the outcomes of their work.

Ontario P.Engs are part of a community of more than 80,000 PEO licence and certificate holders committed to enhancing the quality of life, safety and well-being in the province.
