The atmosphere is the most mobile medium for the transport of pollutants across physical and political boundaries. Air is also fundamental to most life processes on earth, including those of humans. Moreover, the atmosphere is the thin skin that maintains this planet in a habitable state for the life upon it. For all these reasons, governments across Canada pursue active programs – individually and collectively – on air and atmospheric issues. Under 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 that are transported through this medium.
Ministers of the environment agreed to implement a new Air Quality Management System to guide work on air emissions across Canada.
