  • description (ideally a screen shot) of the issue you experienced.

If you are using a different browser or version of a browser than those listed, we would still like to hear about your experience using the portal.

If you are a professional engineer, an engineering intern (EIT) or the holder of a temporary, provisional or limited licence, you may:

  • view the information in your licence profile (to correct information, please contact the Document Management Centre at [email protected].
  • change your chapter affiliation (but the chapter in which you were placed based on your home address will remain your chapter for PEO election purposes);
  • view and update information on your practice and engineering disciplines;
  • change your password;
  • pay PEO fees and the annual fee for the Ontario Society of Professional Engineers, and make charitable donations to the Professional Engineers Foundation for Education (should you have questions, please contact [email protected]);
  • print receipts for fees paid (should you have questions, please contact [email protected]); and
  • manage your subscription to Engineering Dimensions. All PEO licence holders and engineering interns receive the print edition of Engineering Dimensions by mail, unless they opt in to receive a link by email to the digital edition. You may opt in to the digital edition or switch back to the print edition at any time.

If you have submitted a licence application and have been assigned a file number, you may:

  • view and update your contact information;
  • change your password;
  • pay PEO fees and make other payments;
  • register for PEO-assigned exams; and
  • order exam reprints.

If you have accessed PEO’s online services in the past and are trying to log into the new portal by creating a new password, you cannot use the Forgot your Password? link to retrieve your previous password. In this case, you must register on the portal as if you were a new user. Once you are registered, you can retrieve your forgotten password at any time by using the Forgot your Password? link.

To access the PEO portal for the first time, you are asked for four pieces of information, which must match the information in PEO’s database:

  • your licence or application file #;
  • your date of birth;
  • your home phone number; and
  • your home postal code.

You have three attempts to register successfully. If the information you provide does not match the information in PEO’s database, you will be presented with a PEO Error Log ID# and asked to contact PEO, so that we can update the information in the database, or otherwise assist you in registering.

If you used PEO’s online services previously, you are required to set up a new password for the new portal. If you have forgotten your password, you cannot use the Forgot your Password? link to retrieve it to set up this new password. Instead, you must register on the Web portal as if you were a new user. The portal log-in page has the information you need to register. Once you are registered, you may retrieve a forgotten password at any time by using the Forgot your Password? link.

If you have never used PEO’s online services, you must register on the Web portal to begin online transactions with PEO. The information you need to register is on the portal log-in page.

Paying PEO fees online and generating fee receipts through the PEO portal is fast and secure and saves you money. PEO licence and other fees have not increased in several years, at least partly as a result of online transactions lessening the need for PEO to incur printing and mailing costs for hard copy invoices and reminders

With the implementation of new database software, licence holders, engineering interns and now licence applicants are able to interact online with PEO more than ever before, including updating their contact information, downloading editable applications and registering for exams. Requiring these online transactions to occur within a new, updated Web portal enhances the security of the online information you provide us. The new PEO portal adheres to current best practices for system security and data protection, specifically:

  • site pages involving display or transfer of personal user information are secured via HTTPS/SSL/TLS;
  • public Internet clients cannot access the site’s administrative functions;
  • site forms are protected from known intrusions (SQL injection attacks, JavaScript injection attacks, file upload attacks, SPAM, etc.); and
  • sensitive personal data (e.g. passwords) is stored in an encrypted format.
