^a Fully adjusted models are stratified by sex, age (5-year categories), and recent immigrant status and are adjusted for income adequacy quintile, visible minority status, Indigenous identity, educational attainment, labor-force status, marital status, occupation, and ecological covariates of community size, airshed, urban form, and four dimensions of Can-Marg (instability, deprivation, dependency, and ethnic concentration).

^b Deaths were rounded to the nearest 100 for confidentiality.

^c HRs are presented as per 10-μg/m³ increase.
