Professional Engineers Ontario (PEO; known until 1993 as the Association of Professional Engineers of Ontario, APEO)[1] is a self-regulatory body that licenses and governs Ontario's professional engineers.
PEO was created on June 15, 1922.[2] It has a statutory mandate under the Professional Engineers Act of Ontario to protect the public interest.[3] It is also mandated to educate its members about latest developments in engineering and maintaining a Code of Ethics. Licensed professional engineers use the postnominal P.Eng.
PEO consists of 36 chapters,[4] each representing a different geographic area in Ontario. PEO is governed by a Council of 29 members, of which 17 are elected by the licence holders and 12 are appointed by the provincial government.
The organization has collaborated with the Ontario Society of Professional Engineers[5] since 1947 in organizing the Ontario Professional Engineers Awards (OPEA).[6]
