Become a Professional Engineer

In Canada, the professional engineer (P.Eng.) designation represents the highest standards of engineering knowledge, experience and professionalism in the country. 

Individuals may only call themselves a professional engineer, or a P.Eng., if they possess a P.Eng. licence from the Canadian province or territory in which they reside. To become a P.Eng. in Ontario, the person must be licensed by Professional Engineers Ontario (PEO).
