Please note that ongoing wildfires in northern Ontario and Quebec are impacting air quality.  As a result, the Air Quality Index (AQI) & Air Quality Health Index (AQHI) can vary considerably from hour to hour.  What's tolerable in the short-term may not be tolerable in the long-term, especially during outdoor athletic activities.  

We suggest consulting these government sources to monitor Belleville's AQHI & AQI so you can take care and assess your own individual risk:

- Semi-frequent AQHI levels and future forecasts for Belleville can be found here, along with risk assessment sources.  (marginally useful future forecasting)   https://weather.gc.ca/airquality/pages/onaq-043_e.html

- Live AQI readings for Belleville can be found here. (however, unreliable future forecasting beyond hourly readings, does not account for wildfire fluctuations)     https://www.iqair.com/ca/canada/ontario/belleville
