Occupational health and safety (OHS) is a broad industry, which focuses on the physical, mental, and emotional well-being of people at work. 

This field includes all aspects of worker health. From workplace harassment to fire prevention; ergonomics to emergency evacuation procedures. 

In 1976, Manitoba passed The Workplace Safety and Health Act. It laid out standards for safe working conditions, and outlined the responsibilities of employers to maintain those standards.

This move came shortly after Saskatchewan passed North America's very first Occupational Health Act in 1971—making Canada a strong leader in this area.
