Environment Canada has issued a special air quality statement as wildfire smoke causes very poor air quality and reduced visibility in the region.
Officials said air quality and visibility can change quickly over short distances and from hour to hour.
Everyone is at risk during periods of heavy smoke, regardless of age or health status. Residents are advised to limit time outdoors and consider postponing or cancelling outdoor sports, activities and events.
Smoke exposure may cause eye, nose and throat irritation, headaches and a mild cough. More serious symptoms can include wheezing, chest pain or a severe cough. Anyone experiencing a medical emergency should seek immediate medical assistance.
People most vulnerable to wildfire smoke, including seniors, pregnant people, infants and young children, people with existing medical conditions and those who work outdoors, should avoid strenuous outdoor activity and seek medical attention if symptoms develop.
Residents are encouraged to keep windows and doors closed as much as possible, unless cooling their homes during periods of extreme heat takes priority.
Officials also recommend improving indoor air quality by using the highest-quality furnace or ventilation filter the system can accommodate or by using a certified portable air cleaner.
