Health Hazards

The Health Protection and Promotion Act (R.S.O. 1990, c. H.7),1 defines a health hazard as:

  • a condition of a premise
  • a substance, thing, plant or animal other than man, or
  • a solid, liquid, gas or combination of any of them

... that has or that is likely to have an adverse (harmful) effect on the health of a person. This means that anything that worsens someone’s health is a possible health hazard.
