Please note: Air quality can vary across our region, and the risk level shown in the image above may not reflect conditions in your exact location. The risk level above is based on information from Air Quality Ontario and is only increased when an air quality alert is issued by Air Quality Ontario or Environment and Climate Change Canada (ECCC).
For the most accurate information about air quality in your area, visit the AQMap to view air quality conditions from the monitoring station closest to you and follow the recommended health guidance. See below for more information on monitoring local air quality.
Wildfire Smoke Health Guidance
(by 1-Hour Average PM2.5 Level)
| Risk Level | AQHI Category | PM2.5 (µg/m³) | People at Higher Risk | General Population |
|---|---|---|---|---|
| Low Risk | 1-3 | 0-30 | Enjoy your usual outdoor activities. | Ideal air quality for outdoor activities. |
| Moderate Risk | 4-6 | 31-59 | Consider reducing or rescheduling strenuous activities outdoors if you are experiencing symptoms. | No need to modify your usual outdoor activities unless you experience symptoms such as coughing and throat irritation. |
| High Risk | 7-10 | 60-100 | Reduce or reschedule strenuous activities outdoors. Children and older adults should also take it easy. | Consider reducing or rescheduling strenuous activities outdoors if you experience symptoms such as coughing and throat irritation. |
| Very High Risk | 10+ | 101+ | Avoid strenuous activities outdoors. Children and older adults should also avoid outdoor physical exertion. | Reduce or reschedule strenuous activities outdoors, especially if you experience symptoms such as coughing and throat irritation. |
*Note: The AQHI values in this table are based only on fine particulate matter, also called PM2.5. PM2.5 is made up of very small particles in the air and is measured in micrograms per cubic metre of air (μg/m³). The table includes Health Canada messages and recommended actions to help reduce exposure to wildfire smoke. People who are at higher risk, or anyone who has symptoms, should consider taking action when the AQHI is Moderate. Others may not need to take action until the AQHI reaches High or Very High.
People at higher risk include older adults, children, pregnant people, and those with heart or lung conditions. For a more complete list, please see the information below.
Air Quality Key Messages:
Outdoor air quality in Renfrew County and District is usually good for enjoying outdoor activities and generally poses a low risk, even for people who are sensitive to air pollution. However, air quality can change from day to day because of pollution from local and regional sources. Wildfire smoke can cause significant changes in air quality and increase health risks.
Wildfires and wildfire smoke have always occurred in Ontario, but climate change is making them more frequent and severe. As a result, Renfrew County and District is experiencing more air quality events related to wildfire smoke.
Wildfire smoke is a type of air pollution that can affect your health. It can irritate the lungs, cause inflammation, and worsen heart and lung conditions.
Fine Particulate mater (PM2.5) is the main health risk from wildfire smoke
There is no known safe level of exposure to wildfire smoke pollutants. Health effects can occur even at low levels, especially for people at higher risk.
Air quality can be poor even when smoke is not visible or easy to smell. As smoke levels increase, health risks increase. Local air quality information can help people decide when to reduce exposure.
If your community is threatened by an approaching wildfire, be ready to evacuate if directed by local authorities. Keep an evacuation kit prepared. For more information on what to include, visit: Your Emergency Preparedness Guide.
