Repealed Regulations

Ozone-depleting Substances Regulations, 1998 (SOR/99-7)

In 1987, Canada signed the Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol). The Montreal Protocol is a legally binding agreement under which Parties must phase-out the production and consumption (production + import - export) of a wide range of chemicals known to contribute to the ozone depletion. Canada's obligations under the Montreal Protocol are implemented through the Ozone-depleting Substances Regulations, 1998 (ODSR 1998). The ODSR 1998 control the export, import, manufacture, sale, offer for sale and certain uses of ozone-depleting substances (ODS). The consumption of the following ODS has been phased-out in Canada: chlorofluorocarbons (CFC), Halons, Carbon Tetrachloride, 1,1,1-Trichloroethane, hydrobromofluorocarbons (HBFC) and methyl bromide. Consumption of hydrochlorofluorocarbons (HCFC) will be phased out by the year 2030. Under the ODSR 1998, there are exemptions for which a substance can be manufactured, imported or used with a permit. The ODSR 1998 also require that a permit be obtained to import or export used, recovered, recycled and reclaimed ODS. The ODSR 1998 also control certain products that contain or are designed to contain ODS.
