The current study aimed to characterise the association between long-term exposure to fine particulate matter (PM2.5) air pollution with non-accidental, and cause-specific mortality, as well as to investigate the shape of the association between concentration and response. To examine the shape of this association, the study developed a new cohort based on respondents to the 2001 Canadian census long-form. A total of 2.4 million respondents were followed who were non-immigrants aged between 25 and 90 years and did not reside in an institution over a 10 year period for mortality.
