We provide resources to assist our stakeholders in understanding our regulatory role and how we protect the public interest.
As part of its regulatory mandate, PEO establishes, maintains and develops: standards of knowledge and skill; standards of practice for the profession; standards of professional ethics; and promotes public awareness of its role. The following are resources to assist PEO stakeholders--licence holders, applicants, and the public--in understanding their roles and responsibilities and the regulator’s work protecting the public interest.
Resources
Ontario professional engineers are part of a community of more than 87,500 PEO licence and certificate holders committed to enhancing the quality of life, safety and well-being in the province.
As Ontario’s engineering regulator, PEO relies heavily on its volunteers. More than 1,000 professional engineers, engineering interns and non-engineers volunteer their time each year on behalf of the association through their participation.
PEO's mandate, as described in the Professional Engineers Act, is to ensure that the public is protected and that individuals and companies providing engineering services uphold a strict code of professional ethics and conduct.
