Canadians’ health and their social and economic well-being are fundamentally linked to the quality of their environment. Recognizing this, in 2004, the Government of Canada committed to establishing national indicators of air quality, greenhouse gas emissions, and freshwater quality. The goal of these indicators is to provide Canadians with more regular and reliable information on the state of their environment and how it is linked with human activities. Environment Canada, Statistics Canada, and Health Canada are working together to further develop and communicate these indicators. Reflecting the joint responsibility for environmental management in Canada, this effort has benefited from the cooperation and input of the provinces and territories.

This report is part of a suite of documents released under the Canadian Environmental Sustainability Indicators (CESI) initiative.1 Each indicator reported in a given year under CESI has an associated “data sources and methods” report to provide technical detail and other background that will facilitate interpretation of each indicator or allow others to conduct further analysis using the CESI data and methods as a starting point.

This report deals with the underlying methods and data for the air quality indicators, as published in the 2006 CESI report.
