Welcome to the Environment Canada
Stratospheric Ozone Web Site!
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 strong control measures implemented by federal, provincial and territorial governments, changes in technologies and voluntary actions by industry.
This site provides information on the history of stratospheric ozone layer depletion, the science of ozone depletion, Canada?s Ozone Layer Protection Program and the regulatory approach to protect the ozone layer, as well as information on a number of other topics. We hope you enjoy the new website and find it useful and informative.
