Clean Air Day 2021

About Clean Air Day

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.

Celebrate Clean Air Day on June 2nd! Let’s recognize how important good air quality is to our health, our environment, and the economy.

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. This suggests that people exposed to higher levels of air pollution may be at greater risk of becoming ill with COVID-19, with an increase in frequency of 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.
