Practice Advice Resources and Guidelines

PEO offers a variety of practice advice resources to assist licence holders in providing professional and ethical engineering services. 

PEO’s practice advisory team is also available to help licence holders with issues related to professional practice and to verify their responsibilities under the Professional Engineers Act (PEA).

Providing practice advice resources fulfils PEO’s regulatory obligations under the PEA to establish, maintain and develop standards of practice.

Practice Guidelines

Practice guidelines provide advice and recommendations on engineering best practices, specifically around performing engineering work in accordance with the PEA. Practice guidelines define the roles and responsibilities of practitioners, and advice on the expectations of licence holders practising in a particular area.

Practice Bulletins

Practice bulletins provide professional advice on urgent issues, as well as guidance on what is expected of PEO licence holders. Bulletins are also used to provide interpretations or to supplement or update existing guidelines.

Performance Standards

Performance standards provide benchmarks to help practitioners determine the expected level of service. While practitioners are expected to use professional judgement in performing their work, the standards describe only the required outcome of a practitioner’s activities, leaving the methods to the discretion of the engineer.

Performance standards can be found in O. Reg. 260/08, a regulation under the PEA.

Practice Articles

Practice articles appear in Engineering Dimensions magazine, PEO’s official publication. These articles provide licence holders with general information on current practice issues.
