Environmental Burden of Cancer in Ontario

​Read the report

​Cancer Care Ontario and Public Health Ontario have partnered to produce, Environmental Burden of Cancer in Ontario, a report that sheds light on the impact of environmental carcinogens by calculating, for the first time, the annual environmental burden of cancer in Ontario.  Results show that environmental carcinogens are responsible for approximately twice the cancer burden from alcohol consumption and approximately one-half the cancer burden from smoking.

The report estimates how many new cancer cases each year in the province are the result of exposure to 23 carcinogens that exist in our environment.

Key findings in the report include:
  • over 90 per cent of all environmental cancer cases result from exposure to three main carcinogens 
    • 2,090 to 2,990 new cancer cases from UV radiation in sunlight
    • 1,080 to 1,550  new cancer cases from radon
    • 290 to 900 new cancer cases  from fine particles (PM2.5) in air pollution
