  9. Beyond Traditional Borders • First large scale long-termhealth follow-up of a general Canadian population exposed to ambient air pollution • Follows a mobile group of individuals annually (1982-2004) to determine cumulative exposures • Mulitple data sources • T1 Family File – cohort, annual residential postal codes, income • NAPS, NAPR, Satellite Images, Road Maps - exposures • CMDB and CCDB - mortality and incidence of cancer • Census Variables - income, education, occupation, industry • Ontario Health Survey - smoking, alcohol, physical activity

  10. Air Pollution Study • Purpose: • Shed light on the relationship between air pollution, non-accidental deaths and cancer incidence in Canada • To allow for better standards and regulations

  11. National Air Pollution Surveillance System (NAPS)
