Canadian governments have cooperated through CCME since the early 1990’s to address the phase-out of substances such as CFCs and halons that can deplete the ozone layer. CCME through the Federal-Provincial Working Group on Ozone-Depleting Substances and Halocarbon Alternatives developed Canada's Strategy to Accelerate the Phase-Out of CFC and Halon Uses and to Dispose of the Surplus Stocks to achieve an orderly and affordable phase-out of CFCs and halons in Canada.

An important component of the Strategy is the National Action Plan for the Environmental Control of Ozone-Depleting Substances (ODS) and their Halocarbon Alternatives (revised 2001). The Action Plan provides a national framework for a harmonized approach by the federal, provincial and territorial governments to implement an ozone layer protection program.
