The ozone layer is a thin protective layer located in the stratosphere approximately 25-35 km from the Earth’s surface. Unlike the ‘bad’ ground-level ozone which produces smog, stratospheric ozone protects the environment and human health by filtering out damaging UV-B radiation which causes skin cancer, eye cataracts, weakening of the immune system, crop damage and inhibited plant and plankton growth. The substances that deplete the ozone layer are cluorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrobromofluorocarbons (HBFCs) and halons which are mainly used in the refrigeration, air-conditioning and fire extinguishing sectors.
As one of the early signatories to the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, Canada has consistently met or exceeded its obligations under the Protocol. In the last decade federal and provincial governments have undertaken various measures including regulations and the establishment of a Federal/Provincial Working Group (FPWG) on Controls Harmonization (ODS) to ensure the protection of the ozone layer.

Newfoundland and Labrador's Halocarbon Regulations are compatible with other provincial governments. The regulations are reviewed continuously to ensure measures set out in the Canadian Council of Ministers of the Environment (CCME) 2001 National Action Plan for the Control of Ozone-Depleting Substances (ODS) and their Halocarbon Alternatives as well as Canada’s Strategy to Accelerate the Phase-out of CFCs and Halons Uses and to Dispose of the Surplus Stocks (212 KB) are met.
The production and importation of CFCs and Halons were banned in Canada in 1994-1995 under federal government regulations. The restrictions put in place following the Montreal Protocol have resulted in a growing surplus of CFCS and halons due to their replacement with more environmentally friendly alternatives. On January 1, 2001, the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) launched a new not-for-profit environmental organization called Refrigerant Management Canada (RMC). The mission of RMC is to manage the environmental disposal of surplus CFC refrigerant stocks from the stationary refrigeration and air conditioning industry, once they are no longer acceptable for use in Canada.
