💨 Wildfire Smoke Alert for Ottawa & Southern Ontario – Extreme Risk 💨
The Canadian Wildland Fire Information System (CWFIS) has set wildfire risk to extreme across much of Southern Ontario, including Ottawa and surrounding areas. Even smoke from distant fires can seriously affect your indoor air quality.
Wildfire smoke contains fine particles (PM2.5) that can enter your home through windows, doors, cracks, and HVAC systems. These particles can cause burning eyes, runny nose, coughing, and worsen heart and lung conditions. Children, older adults, pregnant people, and those with asthma, COPD, or environmental sensitivities are at higher risk.
Protect Your Family – Key Guidance:
‣ Keep windows and doors closed.
‣ Set your HVAC or air conditioner to recirculate mode and close fresh air intakes.
‣ Use a portable HEPA air purifier (or a well-built DIY box fan + MERV 13 filter) in rooms where you spend the most time — run it on high.
‣ Limit outdoor activities and avoid strenuous exercise.
‣ Wear a well-fitted N95 respirator if you must go outside.
‣ Avoid indoor activities that add particles: no candles, frying food, smoking, or vacuuming without a HEPA filter.
After a smoke event: Ash and residue can linger on surfaces and in ducts. Thorough cleaning is important — especially for environmentally sensitive individuals.
