Ontario workplaces with 20 or more employees are required to have a Joint Health & Safety Committee.
The committee must have at least 2 members: 1 worker member and 1 employer representative. Their primary role is to identify workplace health and safety problems and bring them to the attention of the employer. Special training is required for some members of the committee.
Workplaces with more than 5 but fewer than 20 employees are not usually required to have such a committee. Instead, workers must elect a person to be a health and safety representative.
The Ministry of Labour has published A Guide for Joint Health & Safety Committees and Representatives in the Workplace.
