License-Professional Engineer (P.Eng.) (with PEO since 2001)^*

Updated: 2021-01-22

	Professional Engineers Ontario licenses Ontario’s 83,000 professional engineers, grants temporary, limited and provisional licences to practise professional engineering, and authorizes businesses to provide engineering services to the public. It sets standards for and regulates engineering practice. Under the Professional Engineers Act, its statutory mandate is to serve and protect the public interest where engineering is concerned. Rigorously educated, experienced and committed to a Code of Ethics that puts the public first, licensed professional engineers can be identified by the P.Eng. after their names. The Professional Engineers Act provides that every professional engineer shall have a seal denoting licensure, including the type of licence held. Section 53 of the Act sets out the use of the engineers seal, which has legal implications. The appearance of the seal on documents and drawings indicates that the documents and drawings are final and have been prepared under the supervision of a professional engineer who is assuming responsibility for them. Since engineers assume technical and ethical responsibilities for work done under their supervision, the use of the seal is the engineer's "stamp of approval" about the technical accuracy of the materials.
