Hydrochlorofluorocarbons (HCFCs) are organic and synthetic (i.e., human-made) chemicals. HCFCs have ozone-depleting potential (ODP), therefore, they are identified as ozone-depleting substances (ODS). HCFCs have a lower ODP than CFCs. They are considered acceptable interim substitutes for CFCs and are found in the many of the same applications as CFCs that they replace. They are also used as fire-extinguishing agents.  

Canada is a Party to the Montreal Protocol on Substances that Deplete the Ozone Layer, which requires Parties to gradually phase-out production and consumption of ODS, as well as reduce and eliminate trade in these substances. The Montreal Protocol requires that HCFC production and consumption be phased out by 2020 for all HCFCs, except for servicing applications.
