Environment Canada has issued a smog warning for the Gatineau and Maniwaki areas, blaming wood heating for the rise in pollutants.
According to the agency, wood heating is the most common cause of winter smog warnings in Quebec due to the prevalence of wood-burning stoves and fireplaces.
Levels of air pollutants are expected to increase this evening and remain high into Monday morning.
