Ozone-depleting Substances and Halocarbon Alternatives Regulations

The Ozone-depleting Substances and Halocarbon Alternatives Regulations (ODSHAR) are the means by which Canada meets its obligations under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol). The ODSHAR are modernized Regulations that repealed and replaced Canada’s Ozone-depleting Substances Regulations, 1998 on December 29, 2016.
