Licence holder/EIT names

PEO licence holders and engineering interns are required to keep their online Directory profile up-to-date. Profiles may be updated through the PEO portal or by contacting PEO’s Document Centre if information is inaccurate or missing.

It is PEO's policy to license individuals in their full legal name; this is the name that must be entered in PEO records and corresponds to the name appearing in government issued identification documents that are provided to PEO by the individual. PEO will accept a revision to a full legal name only if provided with appropriate documentation confirming that the Registrar General of Ontario, or a similar authority in another province, has approved the change. A marriage certificate is a valid document for changing a legal name. Visit the Ontario Government website for more information on changing a name.
