Ozone Layer Protection

As one of the early signatories to the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987, Canada has made significant progress in reducing the emissions of ozone-depleting substances through control measures implemented by federal, provincial and territorial governments, changes in technologies and voluntary actions by industry.

This section provides information on the ozone layer, the Montreal Protocol, and Canada's regulatory and voluntary programs to protect the Earth's stratospheric ozone layer.
