About Health & Safety Ontario

Ontario is already a great place to do business, live and work. Making our province, and indeed our country, the healthiest and safest place to work in the world is a prize worth winning. 

Ontario’s Prevention System is made up of the Ministry of Labour (MOL), Workplace Safety and Insurance Board (WSIB), Workers Health & Safety Centre, Occupational Health Clinics for Ontario Workers Inc. and 12 Health and Safety Associations (HSAs).

Health & Safety Ontario (HSO) is the result of a bold move to reorganize the independent efforts of 12 health and safety associations into four streamlined organizations to better serve more than 236,000 Ontario businesses. 

HSO is comprised of:


What this means to your organization:
