Consulting Engineer Designation

PEO's "consulting engineer" designation helps promote recognition of engineers in independent practice. Only a member who has been designated as a consulting engineer by PEO can use the restricted title “consulting engineer.” Holding a certificate of authorization (C of A) licence from PEO alone does not entitle professional engineers to call themselves “consulting engineers” or advertise their services as consulting engineers. Firms also require permission from PEO to use the title “consulting engineers” in their corporate names.

Requirements for designation as a consulting engineer include:

  • being a PEO member in good standing;
  • having at least five years of experience satisfactory to Council, in excess of the four-year experience requirement for licensure;
  • being "primarily engaged" in the independent practice of professional engineering in Ontario for the last two years. To be considered primarily engaged in independent practice, applicants must either derive at least 50 per cent of their earned annual income from consulting engineering or spend at least 50 per cent of their work time in consulting. The applicant must also either hold a Certificate of Authorization from PEO, or be a partner or an employee of a firm holding a Certificate of Authorization, in which case they must be designated in the firm's C of A application as a P. Eng. who assumes responsibility for, and supervises, the firm's professional engineering services.
