Air Quality Continues to Improve

Ontario Releases 41st Annual Air Quality Report

Ontario's annual air quality report shows levels of many air pollutants have dropped across the province and Ontario's air quality continues to improve.

The Ontario government has taken strong action to reduce air pollutants and ensure cleaner air for the people of the province.  Today's cleaner air quality comes as the result of:

  • Replacing coal-fired generation with cleaner, renewable energy sources.
  • Lowering emissions from cars and trucks and investing in public transit.
  • Stronger regulations to reduce greenhouse gases and other industrial emissions.
  • Working with the federal government and the United States to address transboundary air pollutants that impact Ontario.  

Reducing air pollutants and protecting the environment is part of the government's plan to create a sustainable economy that creates jobs for Ontario families. 

Quick Facts

  • There are 40 Air Quality Index (AQI) monitoring stations across the province that provide around-the-clock information on air quality.
  • Over the past decade, levels of air pollutants such as fine particulate matter, nitrogen dioxide, sulphur dioxide, carbon monoxide and summer time ground-level ozone have declined.
  • Cleaner air lowers the health risks associated with pollution such as asthma and other respiratory diseases.
  • Earth Week takes place from April 22-26, 2013.
