The first law related to professional engineering in Ontario was created in 1922 and allowed for the creation of a voluntary association to oversee registration of engineers. The Act of 1922 was "open", meaning that membership in the association was not mandatory for those practising engineering.
In Ontario, regulation of engineering practice dates to 1937, when the Professional Engineers Act was amended and the engineering profession was "closed" to non-qualified individuals; that is, licensure was made mandatory for anyone practising professional engineering. The provincial government determined that it would be in the public interest to restrict the practice of engineering to those who were qualified, and the right to practise was "closed" to those not licensed by PEO as a result of the failures of bridges and buildings, which had been designed by unskilled individuals.
The Professional Engineers Act was amended in 1946, 1949, 1960, 1969, 1984, 2010 and 2017. Each amendment strengthened PEO's ability to regulate professional engineering practice, by, among others:
expanding the scope of professional engineering to encompass modern developments, including different classes of licensure; enabling PEO to pass regulations relating to a Code of Ethics, professional conduct, negligence and incompetence, and detailing sanctions for incompetence and professional misconduct; regulating engineering partnerships and corporations; recognizing the need to grant licences to practise in Ontario to those living outside the province; and
defining a formal complaints procedure.
Regulation 941/90 of the Act
Regulation 941 of the Professional Engineers Act, amended to O.Reg. 71/15, is a regulation made to provide additional details and guidance for implementation of the Act. For example, the Regulation prescribes the process to be followed when electing professional engineers to Council. With respect to professional practice, the Regulation prescribes a Code of Ethics, defines incompetence and professional misconduct, addresses the requirement for practitioners to report unsafe situations and unethical practices, and states that all licence holders shall have a seal and describes its use.
Regulation 260/08 of the Act
Regulation 260 of the Professional Engineers Act establishes performance standards for professional engineers, initially relating to general review of construction of a building as provided for in the building code and to demolition. It was expanded in 2014 to include standards for design of certain buildings, engineering evaluation reports under the Safe Drinking Water Act, 2002, and environmental site assessments. It was further revised in 2016 to reference PEO’s Practice Standard for Review of Tower Cranes as required by the Occupational Health and Safety Act.
