Air pollutants have the potential to impact environment and human health both locally and across political and geographic boundaries. Governments across Canada pursue active programs on air issues both individually and collectively. Through CCME, governments have engaged in a variety of activities directed at specific air issues, such as acid rain, ozone-depleting substances, and standards for toxic substances to improve air quality and achieve health and environmental benefits.
In 2012 ministers of the environment, with the exception of Québec, agreed to implement a new Air Quality Management System (AQMS) to guide work on air emissions across Canada. AQMS is intended to provide a comprehensive approach for improving air quality in Canada and to publicly report on Canada's air quality.
CCME announced new Canadian ambient air quality standards (CAAQS) for nitrogen dioxide in 2017 and for sulphur dioxide in 2016. CCME is currently reviewing the CAAQS for ground level ozone.
CCME's Air Management Committee is responsible for implementation of many elements of AQMS and for reporting on CCME’s various commitments on air issues.
Standards, progress reports, guidelines and codes of practice on air issues can be found in the resources section of this site.
One of the key elements of the Air Quality Management System (AQMS) is the involvement of stakeholders in both the development of the system, and review of its implementation.…
While significant progress has been made to reduce air pollution, poor air quality remains a serious issue in some areas of Canada. CCME is committed to ongoing reporting on Canada’s air quality inc…
