Read the full government alert

Smoke is causing or expected to cause poor air quality and reduced visibility. Air quality and visibility due to wildfire smoke can change rapidly over short distances and from hour to hour. As smoke levels increase, health risks increase. 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 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 reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms. 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, 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. Learn more at https://www.canada.ca/wildfire-smoke.

about this website

should i trust this website?
yeah. it uses Environment Canada data to show what Fort Simpson’s air is like.
it can’t tell you exactly what the air is like on your street.
is this an official government website?
no. Ehtoz is independent. it uses official government data, but it isn’t affiliated with Fort Simpson, Northwest Territories, or Environment Canada.
who made this?
i’m Amrit Sharma. i live in Toronto and have spent more than a decade working on air quality and climate change.
i serve on the board of OpenAQ, helping make air-quality data more open and useful. the Asian Development Bank recently invited me to help develop a regional clean-air action plan with countries across South Asia.
i work at ecobee, designing grid-resiliency programs that help keep the lights on during heat waves and winter storms.
what should i do next?
check the latest official forecast before making plans outside.
