For Spring 2026, changes are expected to include... 1) ECCC's initiative to introduce free-form polygons to represent the true threat area of a weather hazard is tentatively set for June 2026 deployment. Data changes will appear in CAP following this deployment, 2) marine alerts will now be issued for smaller zone splits in certain areas of Atlantic and Pacific waters and 3) other minor improvements and corrections. For more information on these changes: https://comm.collab.science.gc.ca/mailman3/hyperkitty/list/dd_info@comm.collab.science.gc.ca/ | Notification de service – avril 2026: Le service du PAC d’Environnement et Changement climatique Canada (ECCC) subit périodiquement des changements à mesure que le système d’alerte évolue. Pour le printemps 2026, il y aura des changements incluant... 1) l’initiative d’ECCC visant à introduire des polygones libres pour représenter la véritable zone de menace d’un danger météorologique devrait être déployée provisoirement en juin 2026. Des changements de données apparaîtront dans le PAC à la suite de ce déploiement, 2) les alertes marines seront désormais émises pour des subdivisions de zones plus petites dans certaines régions des eaux de l’Atlantique et du Pacifique et 3) d’autres améliorations et corrections mineures.

There may be temporary improvement this afternoon however very poor air quality will return to all regions this evening and may persist into the weekend. ### During heavy smoke conditions, everyone’s health is at risk regardless of their age or health status. Limit time outdoors. Reschedule or cancel outdoor sports, activities and events. You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance. People more likely to be impacted by wildfire smoke, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should avoid strenuous activities outdoors and seek medical attention if experiencing symptoms. For further information visit the website https://www.airqualityontario.com/ or contact the Ontario Ministry of the Environment, Conservation and Parks at 416-314-6666. Visit http://www.airhealth.ca for information on how to reduce your health risk and your personal contribution to pollution levels, as well as for current and forecast AQHI values. Please continue to monitor alerts and forecasts issued by Environment Canada. When indoors, keep windows and doors closed as much as possible. When there is an extreme heat event occurring with poor air quality, prioritize keeping cool. Protect your indoor air from wildfire smoke. Actions can include using the highest quality air filter that your ventilation system can handle and/or a certified portable air cleaner that can filter fine particles. If you must spend time outdoors, limit the time as much as possible. A well-constructed, well-fitting and properly worn respirator type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to the fine particles in the smoke. Even though exposure may be reduced, there can still be risks to health. Check in on others who are in your care or live nearby who may be more likely to be impacted by wildfire smoke. Always follow guidance from local authorities.

qualité de l'air - en vigueur La fumée des feux de forêt dans le nord-ouest de l'Ontario continue d'occasionner une très mauvaise qualité de l'air et une visibilité réduite ce matin. Les conditions pourraient s'améliorer temporairement cet après-midi, mais la qualité de l'air redeviendra très mauvaise dans toutes les régions ce soir et elle pourrait le rester jusqu'en fin de semaine. ### Pendant les périodes de fumée dense, la santé de chacun est à risque, quels que soient son âge ou son état de santé. Limitez le temps que vous passez à l'extérieur. Réorganisez ou annulez les activités sportives, activités ou événements à l'extérieur. Vous pourriez ressentir les symptômes légers et courants comme une irritation des yeux, du nez et de la gorge, ou plus graves, mais moins fréquents, comme des douleurs à la poitrine ou une toux sévère. Si vous pensez avoir une urgence médicale, demandez une assistance médicale immédiate. Les personnes les plus à risque quant aux effets de la fumée des feux de forêt sur la santé, notamment les personnes de 65 ans et plus, les personnes enceintes, les nourrissons et les jeunes enfants, les personnes qui ont déjà des problèmes de santé chroniques ou une maladie et les personnes qui travaillent à l’extérieur, devraient éviter les activités physiques exténuantes à l’extérieur et demandez une assistance médicale en cas de symptômes. Pour de plus amples renseignements, visitez le site https://www.qualitedelairontario.com/ ou communiquez avec le ministère de l'Environnement, de la Protection de la nature et des Parcs de l'Ontario au 416-314-6666. Consultez le site http://www.coteairsante.ca pour en savoir plus sur comment réduire les risques pour la santé et comment contribuer à réduire la pollution, de même que pour connaître les valeurs actuelles et prévues de la CAS. Veuillez continuer à surveiller les alertes et les prévisions émises par Environnement Canada. Lorsque vous êtes à l’intérieur, gardez les fenêtres et les portes fermées autant que possible. En cas de chaleur extrême et de mauvaise qualité de l’air, la priorité est de rester au frais. Protégez l'air intérieur contre la fumée des feux de forêt. Les mesures à prendre comprennent l’utilisation d’un filtre à air de la meilleure qualité que votre système de ventilation puisse supporter ou d’un purificateur d’air portable certifié capable de filtrer les particules fines. Si vous devez passer du temps à l'extérieur, limitez le temps autant que possible. Le port d'un masque respiratoire N95 homologué par le NIOSH de qualité, correctement porté et ajusté ou l'équivalent (KN95 ou KF94) peut réduire l'exposition aux particules fines dans la fumée. Même si l'exposition est réduite, il peut subsister des risques pour la santé. Prenez des nouvelles de vos voisins, de vos amis et de votre famille, surtout des personnes les plus à risque d'être affectées par la fumée des feux de forêt. Suivez toujours les conseils des autorités locales.
