Ontario JHSC Certification Part One Practice 2026
Most Ontario workplaces with 20 or more workers need a joint health and safety committee with at least one certified worker member and one certified employer member. Certification means passing CPO-approved Part One and Part Two training, then a Refresher every 3 years. This is independent practice for the Part One topics and evaluation.
Quick answer
Pass mark: Part One ends with a standardized evaluation in a form acceptable to the ministry, with a 75% pass mark and at least one hour allotted. Your CPO-approved provider runs and marks it.
