Which of the following best represents a licensed professional engineer?

The option that best represents a licensed professional engineer is one who holds a P.Eng. designation. This designation indicates that the individual has met the rigorous requirements set by the Professional Engineers of Ontario (PEO), which includes not only completing an accredited engineering degree but also gaining relevant work experience and passing the necessary examinations.

Holding a P.Eng. designation signifies that the person is authorized to practice engineering in Ontario, which includes the responsibility to uphold the standards of safety, ethics, and professional conduct in their field. Therefore, it is more than just completing an educational program or passing an exam; it reflects a recognized level of professional competence and accountability within the engineering profession.

In contrast, while completing an engineering degree, passing a PEO exam, or being a member of an engineering association may indicate a certain level of education or involvement in the field, they do not grant the full authority or recognition that comes with the P.Eng. designation. The designation is specifically what legitimizes the individual as a licensed professional engineer capable of taking on the responsibilities and duties that come with the profession.
