Brief Description Smog Warning
Detailed Description High concentration of pollutants are expected and will result in poor air quality, especially in urban areas where pollutant emissions are higher. ### Smog especially affects asthmatic children and people with respiratory ailments or heart disease. It is therefore recommended that these individuals avoid intense physical activity outdoors until the smog warning is lifted. In Quebec, wood heating is the main source of fine particles that contribute to smog during winter. This activity generates the largest number of these particulates, more than industrial activities and transportation. Please consult your municipality's website to find out if there are any rules governing the use of wood-burning stoves or fireplaces in your community. Additional information: To learn more about the Info-Smog program, go to Environment Canada?s website at https://www.canada.ca/en/environment-climate-change/services/info-smog.html. For air quality indexes in Quebec, visit the website of the Ministère de l'Environnement et de la Lutte contre les changements climatiques at https://www.iqa.environnement.gouv.qc.ca/contenu/index_en.asp. For the air quality index in Montréal, visit the Réseau de surveillance de la qualité de l?air de la Ville de Montréal?s website at https://montreal.ca/en/topics/air-quality. To learn more about the effects of smog on your health in Québec, visit the Ministère de la Santé et des Services sociaux?s website at https://www.quebec.ca/en/health. You can also visit the Direction régionale de santé publique de Montréal at https://santemontreal.qc.ca/en/public/.
