August 28, 2020

CCME has posted the Guidance Document on Achievement Determination for Canadian Ambient Air Quality Standards for Nitrogen Dioxide and the Guidance Document on Achievement Determination for Canadian Ambient Air Quality Standards for Sulphur Dioxide.

CCME has established Canadian Ambient Air Quality Standards (CAAQS) for nitrogen dioxide and for sulphur dioxide for 2020 and 2025. These two documents outline guidance on the monitoring, procedures and methodologies to use to help ensure that reporting on CAAQS achievement status for these pollutants is comparable among provinces and territories.
