Chlorofluorocarbons (CFCs) are organic and synthetic (i.e., human-made) chemicals consisting of carbon, chlorine and fluorine. They are hydrocarbon derivatives where all hydrogen atoms are replaced by chlorine and fluorine atoms. CFCs are found in numerous applications: refrigerants (refrigeration, air-conditioning), solvents, foam blowing agents (flexible and rigid foams), and others.

CFCs have ozone-depleting potential (ODP); thus, it is identified as an ozone-depleting substance (ODS).

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. Since January 1st, 1996, the manufacture, import and export of CFCs has been prohibited in Canada, except for use as feedstock, as analytical standards, or essential uses.
