Clean Air Day 2021

About Clean Air Day

Celebrate Clean Air Day on June 2nd! Let’s recognize how important good air quality is to our health, our environment, and the economy. This year we look at the impacts of traffic-related air pollution and how we can reduce it to protect our health. Check out the video to learn how!

Air pollution is a problem, both on a global scale and for local communities. It is one of the most significant environmental challenges affecting public health, and one of the most avoidable causes of death and disease. Evidence shows that exposure to air pollution increases susceptibility to respiratory viral infections and pneumonia. Health experts have warned that people with these pre-existing health conditions may be more vulnerable to becoming ill with COVID-19, and those who become ill are more likely to experience the most severe outcomes.

The Government of Canada is taking action on air pollution to ensure that Canadians have clean air and a healthier environment. We are also working to address sources of air pollution around the world through the United Nations and leading on important initiatives such as the Powering Past Coal Alliance.

Our individual and collective actions contribute to the quality of the air. So let’s do our part to protect and preserve it for future generations.

Clean Air Day at home

As many Canadians spend more time at home during the COVID-19 pandemic, we have online resources to help you recognize the importance of clean air at home. Check out the following links to learn about air quality, how to protect yourself against air pollution and what you can do to help keep the air we breathe clean.

Fun facts

  • In 1999, Canada declared Clean Air Day an annual celebration during Canadian Environment Week.
  • Air fresheners don’t clean the air. They mask odours with another scent that may contain chemicals that can cause irritation or health issues.
  • In addition to providing shade from the sun, trees also release large amounts of moisture. This helps cool and cleanse the atmosphere.
  • Canadians spend on average 90% of our day indoors. While we continue to practice physical distancing by staying home, indoor air quality is more important than ever.
