Air Quality (Outdoor)

Poor outdoor air quality poses a significant risk to public health in Halton Region and in many other communities in southern Ontario. It does not matter who you are, where you live or the state of your health, the quality of the air you breathe each day affects you. 

What are the major sources of air pollution in Halton?

  • Fuel consumption: for heating air and water in buildings and electricity generation.
  • Industrial and Commercial sources.
