The Examination of Accepted Workplace Fatality Claims Within Ontario and Canada

Significance: Occupational cancer occurs as a result of exposure to workplace carcinogens.  These exposures may have occurred as many as thirty years prior to cancer onset.  Further, workers that are no longer directly exposed to carcinogens still continue to be at risk. In 2006, Sharpe and Hardt...

Occupational exposure limits for carcinogens in Ontario workplaces: Opportunities to prevent and control exposure

Significance: Nearly 160 workplace factors are known or likely to cause cancer in humans according to the International Agency for Research on Cancer. Many of these carcinogens are found in workplaces, such as industrial chemicals, pesticides, and radiation. Estimates of the number of cancers that are...

Analysis of the Ontario Ministry of Labour's MESU exposure database

Significance: Analyzing past exposure data can give us important information on which occupations and industries were overexposed in the past and may continue to be overexposed in the future, where there are gaps in our knowledge, and where intervention efforts should be targeted. Moreover, exposures...

The Toronto lung cancer case-control study and SYNERGY project

Significance: Workers are often exposed to multiple carcinogens in their workplace, or over the course of their working life. The effect of these carcinogens in combination is mostly unknown. Studying the interaction between multiple occupational carcinogens is difficult, as the low numbers of people...

Wood dust and sinonasal cancer in Canada

Significance: Wood dust is classified as a human carcinogen based on evidence of very high risks of sinonasal cancer, particularly adenocarcinomas, in woodworkers. However, controversy remains regarding whether dust from all tree species is carcinogenic and some believe that the risk of cancer is limited...

Exposures to emerging environmental contaminants and risk of breast cancer in young women: A case-control study using biomarkers of exposure

Significance: Breast cancer is the most commonly diagnosed cancer in Canadian women, and it is the leading cause of death in young women. Little is known about the modifiable risk factors for breast cancer and inconsistent findings on the associations between environmental, occupational and dietary...

Shiftwork in Canadian industries: A probable cancer risk factor

Significance: Night-time shiftwork has been classified as ‘probably carcinogenic to humans’ by the International Agency for Research on Cancer and was identified as a research priority by Occupational Cancer Research Centre stakeholders. Approximately 18.5% of the working population in Canada, or...

Occupational cancer surveillance using the 1991-2006 Canadian census mortality & cancer cohort

Significance: There are approximately 60 well-established workplace carcinogens identified by the International Agency for Research on Cancer (IARC). However, there are over 100 industrial chemicals and other agents that are suspected to cause cancer, and many more have never been studied. Currently...

Surveillance of occupational cancer risks through linkage of WSIB claims to the Ontario Cancer Registry: a pilot study

Significance: There are approximately 60 well-established workplace carcinogens. However, there are many more industrial chemicals and other agents that are suspected to cause cancer, and still more that have never been studied. Currently, Canada lacks any rapid means to assess whether there is an increased...

Review of Canadian studies that have measured exposure to workplace carcinogens

Significance: There is a large body of research on occupational exposures in Canadian workplaces, but there is no central repository for this information. Having a database in which information from different studies could be collected and analyzed would allow researchers to identify overexposed worker...
