Do YOU know the quality of air you breathe? Many people do not. 

Air quality (AQ) and its impacts are rarely discussed. It remains a silent killer. 

Breathe Easy is looking to change that.


A little bit about Breathe Easy:

  • We are a citizen science initiative driven by volunteers and advisors
  • We're tracking air quality throughout Ottawa. We are on the hunt for ‘hot spots’, where the air pollution levels are potentially dangerous to our health
  • We have also been researching work by others, gathering current information in this subject area
  • We are cooperating with a research group from the Ottawa Hospital Research Institute
  • We are continuing to expand the project. Interested in volunteering? Fill out this form!

What do we know so far?

  • While Ottawa's single government-operated AQ station tends to report AQ in the low risk range, we know that levels of air pollution vary quite a bit throughout the city. Our goal is to understand the air quality across Ottawa, using citizen science and low-cost monitors.

Surprise — it’s air pollution.

While exposure to air pollution is the fourth-leading risk factor for death worldwide, it remains a silent public health emergency, as noted by WHO director-general Dr. Tedros Adhanom Ghebreyesus.
