•We studied childhood asthma onset and residential exposure to industrial emissions.•We used a population-based birth cohort in Quebec, Canada, 2002–2011.•Residential exposure to industrial emissions was estimated from dispersion modeling.•Ambient PM2.5, NO2 and SO2 from industries was associated with asthma onset.•Associations were independent from those of regional PM2.5 and traffic-related NO2.
