Status: in progress
This study will estimate the number of cancers and cancer deaths occurring in Canada due to occupational exposure to carcinogens. The term ‘burden’ is used to refer to the human impact (deaths, illness) and the economic costs (health care, productivity) associated with a cause or group of causes.
Millions of Canadians are exposed to a wide range of known and suspected carcinogens in the workplace. These include industrial chemicals, metals, engine exhaust, fibres and dusts, solar UV radiation, second-hand smoke and night work. However, the impact of these exposures is less clear. Researchers have estimated the number of work-related cancers that occur in other countries, but a study of this type has not been undertaken in Canada on a national scale.
To derive occupational cancer estimates specific to the Canadian context, we will make use of national and provincial cancer statistics, literature reviews on the cancer risks associated with workplace exposures, and estimates of historical exposures in Canada. The end result will be a series of robust province- and sex-specific estimates for the cancers caused by forty-four occupational carcinogens and twenty-four cancer sites.
First, this project will help raise awareness of occupational exposure as an important causal factor in cancer etiology. We will target our results towards primary care physicians and their professional associations to raise awareness in the medical community and improve early recognition of disease.
Second, the results of this project will be useful in highlighting priority areas for prevention activities. Estimates will direct attention to where the greatest number of people will be impacted, and data produced on economic costs will provide added importance for policy makers. The projections component of this project will make it possible to demonstrate the impact of decreasing or eliminating exposure to specific substances and factors on future cancer rates.
This project is nearing completion.

- In November 2015, OCRC hosted a meeting on Preventing the Burden of Occupational Cancer in Canada. The meeting brought together stakeholders and scientists to share interim findings from the burden study and to begin discussing how to use these findings to promote prevention. Please click here to see materials from the meeting, and a report highlighting the major themes that arose from the discussion.
This study received a four-year, $1 million grant from the Canadian Cancer Society Research Institute, covering 2012-2016.
