Ontario’s Occupational Health and Safety (OH&S)


Ontario’s Occupational Health And Safety (OH&S) legislation was originally modeled after the British Factory Act of the 17th century. The Factory Act of 1884 was the first industrial safety legislation in Ontario. The Factory Act of Ontario remained vague, unenforceable and biased toward production and the employer for the next 80 years.


Other notable milestones in Ontario’s health & safety history include:

  • The Factory Act of 1884
  • Industrial Safety Act of 1964
  • The Ham Royal Commission
  • The Occupational Health & Safety Act of 1980
  • Bill 208 and the Amendment of the OHSA in 1990
  • Health Care and Residential Facilities Regulation
  • Workplace Safety and Insurance Act (Bill 99)

What’s Next for Ontario


As PSHSA continues to work with Ontario’s public and broader public sector workers and employers, we strive to keep Ontario’s workers healthy and safe while on the job. There are many emerging occupational health & safety hazards in the workplace.

Some of our current initiatives addressing emerging issues are:

Workplace Violence in Healthcare
PSHSA has been demonstrating thought leadership and addressing some of the most challenging and complex issues related to workplace violence. By working with Healthcare consultants, employer and labour groups, the Ministry of Labour, senior leaders, managers and front line staff, PSHSA is working to provide tools and resources for organizations to address this prevalent issue.

Mental Health
With the release of the 2013 National Standard of Canada for Psychological Health and Safety in the Workplace, organizations have been seeking support to address the hazard and implement successful prevention approaches within their Health and Safety program.
