Service Notice – June 2025: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For 2025, changes are expected to include... 1) ECCC's initiative to upgrade the presentation of alerts into Colour-Coded Weather Alerts is planned for deployment for later in 2025. Data changes will appear in CAP-CP upon this deployment, 2) SAME event codes for a few alert types are updated 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 – juin 2025: Le service du PAC d’Environnement et Changement climatique Canada (ECCC) subit périodiquement des changements à mesure que le système d’alerte évolue. Pour 2025, il y aura des changements incluant... 1) l'initiative d'ECCC visant à améliorer la présentation des alertes sous forme d'alertes météorologiques codées par couleur est prévue d’être déployée plus tard en 2025. Des changements aux données apparaîtront dans le PC-PAC lors de ce déploiement, 2) des codes d’événement MSSC pour quelques types d’alerte ont été mis à jour et 3) d’autres améliorations et corrections mineures.

Elevated pollution levels are expected to continue late this evening before diminishing overnight. Moderate risk AQHI values are expected through late this evening with the potential of short-term high risk AQHI values as a result of ozone combining with residual smoke. ### When air pollution levels are high, everyone should limit time outdoors. Consider reducing or rescheduling 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 outdoor air pollution, 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 reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms. 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 outdoor air pollution. Actions can include using a clean, good quality air filter in your ventilation system and/or a certified portable air cleaner. Check in on others who are in your care or live nearby who may be more likely to be impacted by outdoor air pollution. Always follow guidance from local authorities.

Elevated levels of pollution due to ground level ozone is expected again today. Air Quality Health Index (AQHI) values are expected to reach moderate to high risk this afternoon and evening as elevated levels of ozone are expected. ### When air pollution levels are high, everyone should limit time outdoors.
