Canadian Ambient Air Quality Standards Handbook

February 26, 2025 in New Documents

CCME has posted the Canadian Ambient Air Quality Standards Handbook.

Canadian Ambient Air Quality Standards (CAAQS) are health and environment-based air quality objectives for pollutant concentrations in outdoor air. CAAQS are the major drivers for actions to improve air quality across Canada by all jurisdictions under the Air Quality Management System. This document compiles information about CAAQS and answers the most common questions related to their history, purpose, development and implementation.

 The publication can be found here or through CCME’s searchable resource browser.
