Canadian Ambient Air Quality Standards for Sulphur Dioxide

October 14, 2016

Environment Ministers have announced new Canadian Ambient Air Quality Standards (CAAQS) for sulphur dioxide (SO2).

The new CAAQS for SO2 will reduce emissions linked to respiratory health problems, particularly for children and adults with asthma, and environmental impacts such as acid rain and smog. These standards were developed through a collaborative multi-stakeholder process that included industry associations, health and environmental organizations, Indigenous peoples organizations and governments.
