For an overview of the application process, see the How to become a Professional Engineer in Ontario presentation.

Requirements for Licensure

As a licence holder in the province, Ontario P.Engs are part of a community of more than 80,000 professionals committed to enhancing the quality of life, safety and well-being of all Ontarians.

To be granted a licence to practise professional engineering in Ontario, an applicant must:

  • be at least 18 years old;
  • be of good character;
  • meet PEO's stipulated academic requirements for licensure (hold an undergraduate engineering degree from a Canadian Engineering Accreditation board (CEAB)-accredited program, or possess equivalent qualifications), and, if required, successfully complete any technical exams.
  • fulfill the engineering work experience requirements (demonstrate at least 48 months of verifiable, acceptable engineering experience, at least 12 months of which must be acquired in a Canadian jurisdiction under a licensed professional engineer); and
  • successfully complete PEO’s Professional Practice Examination (PPE).

Engineering Intern Program

Applicants may also register for PEO's Engineering Intern (EIT) program, which provides guidance and assistance to engineering graduates as they acquire the 48 months of acceptable engineering work experience, including annual reviews of experience to ensure that an applicant is “on the right track” for licensing.

Financial Credit Program

Both international and Canadian engineering graduates may be eligible to apply for their Ontario engineering licence at no cost through PEO's Financial Credit Program.

International Engineering Graduates

International Engineering Graduate applicants are not required to be a Canadian citizen or landed immigrant, making it easier for those from outside of Canada to apply for and obtain a licence.

P.Eng. from another Province

If you already hold a P.Eng. licence from another Canadian engineering association/order, a national mobility agreement between all the provinces and territories allows you to move between provinces and territories without having to repeat the entire licensing process. PEO applicants who are licensed as professional engineers in good standing in another Canadian engineering association/ordre are not required to submit transcripts or write PEO’s Professional Practice Examination.


Applicants who have disabilities that require accommodation are advised to contact a staff representative. They will have their needs assessed on a case-by-case basis and every reasonable effort will be made to accommodate them.
