Smoke from northwestern wildfires driving very poor air quality
Environment and Climate Change Canada has issued an orange-level air-quality warning for the Waterloo region and Guelph after smoke from wildfires in northwestern Ontario moved across southern parts of the province. The agency says the smoke is producing very poor air quality and reduced visibility in the area.
The advisory, upgraded from yellow to orange on Wednesday, was in effect as hazy, smoke-filled skies blanketed Kitchener, Waterloo and neighbouring communities. Environment Canada said those conditions are likely to persist until Friday.
Health effects and official guidance
Environment Canada set out expected symptoms and urged caution. The agency said:
“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.”
Local public-health and meteorology officials have advised residents to limit how much time they spend outdoors while the smoke persists, and to keep windows and doors closed where possible to reduce indoor smoke infiltration.
- Those with respiratory or cardiovascular conditions, older adults, children and pregnant people are at higher risk from smoke exposure.
- Consider moving strenuous outdoor activity indoors or postponing it until air quality improves.
- If you experience severe symptoms such as difficulty breathing or chest pain, seek immediate medical attention.
