Professional Engineers Ontario (PEO)


Established on June 14th, 1922, Professional Engineers Ontario (PEO) is the licensing and regulating body for engineering in the province. PEO's mandate, as described in the Professional Engineers Act, is to ensure that the public is protected and that individuals and companies providing engineering services uphold a strict code of professional ethics and conduct. 

With more than 80,000 licence and certificate holders, the province is divided into 5 regions and 36 local chapters. Each chapter provides a crucial link between members-at-large and the PEO council. The main focus of the chapters is to promote the value of engineering to local communities through:

  • organizing licence certificate ceremonies
  • hosting technical seminars
  • hosting social events
  • offering professional networking opportunities
  • hosting education outreach events

Lambton Chapter

The Lambton Chapter covers the area shown including Sarnia, Wallaceburg, Glencoe, and Grand Bend with approximately 1,000 members.

Many members work in the chemical factories and oil and gas refineries of the Sarnia area, collectively known as "Chemical Valley" due to their large number and concentration. This area has a long history of industries requiring engineering. The petroleum industry in the Sarnia area began around 1858. The establishment of Polymer Corporation in 1942 gave rise to a major petrochemical centre.

Our main goal is to support our members, through technical and social events and also to promote the engineering profession through education outreach events.
