Fact sheet for refrigeration and air-conditioning service contractors

Information for Service Contractors Pertaining to Refrigeration and Air-Conditioning Systems

This fact sheet focuses on the provisions of the Federal Halocarbon Regulations, 2003 that relate specifically to service contractors for refrigeration and air-conditioning systems. It is not intended to replace the full legal text of the Regulations or to provide legal opinions. You are advised to retain a lawyer should you require a legal opinion.

What are halocarbons and why are they regulated?

Halocarbons are synthetic chemical compounds made up of carbon and one or more halogens (chlorine, bromine and fluorine). Common halocarbons include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs).

Emissions of halocarbons can lead to ozone layer depletion and contribute to climate change.

How are halocarbons regulated?

In Canada, the federal, provincial and territorial governments have requirements in place to manage halocarbons. At the federal level, Environment Canada administers two regulations under the Canadian Environmental Protection Act, 1999:

  • the Ozone-depleting Substances Regulations, 1998, which control the import, export, manufacture, use, sale and offer for sale of ozone-depleting substances; and
  • the Federal Halocarbon Regulations, 2003, which are discussed in this fact sheet.

In addition to federal legislation, each province and territory controls halocarbons in activities that come under its jurisdiction.

Do the Federal Halocarbon Regulations, 2003 apply to me?

The Federal Halocarbon Regulations, 2003 apply to you if you are a service technician or mechanic working on a refrigeration or air-conditioning system that is

  • owned by the federal government (e.g., departments, boards or agencies, Crown corporations) or by federal works or undertakings; or
  • located on Aboriginal or federal lands (including all tenants on such lands).

What are federal works and undertakings?

A federal work or undertaking is any work or undertaking that is within the legislative authority of the Parliament of Canada, including but not limited to

  • a work or undertaking operated for or in connection with navigation and shipping, whether inland or maritime, including the operation of ships and transportation by ship;
  • a railway, canal, telegraph or other work or undertaking connecting one province with another, or extending beyond the limits of a province;
  • a line of ships connecting a province with any other province, or extending beyond the limits of a province;
  • a ferry between any province and any other province or between any province and any country other than Canada;
  • airports, aircraft and commercial air services;
  • a broadcast undertaking;
  • a bank;
  • a work or undertaking that, although wholly situated within a province, is before or after its completion declared by Parliament to be for the general advantage of Canada or for the advantage of two or more provinces (e.g., nuclear facilities, feed mills); and
  • a work or undertaking outside the exclusive legislative authority of the legislature of the provinces.

What else do I need to know?

Servicing

Only a certified person may do work (installing, servicing, leak testing, charging or other work that may result in the release of a halocarbon) on a refrigeration or air-conditioning system.

All such work must be done in accordance with the Refrigerant Code of Practice.

Before any such work is started, any halocarbon that would otherwise be released during these procedures must be recovered into a container designed and manufactured to be refilled and to contain that specific type of halocarbon.

Once such work is completed, an entry describing the work must be made in a service log containing the information outlined in item 5 of Schedule 2 of the Federal Halocarbon Regulations, 2003.

Leak testing

A leak test is required before charging any refrigeration or air-conditioning system, except to charge a system for a period, up to seven days, that is necessary to prevent an immediate danger to human life or health.

Except for small refrigeration and air-conditioning systems and air-conditioning systems designed for occupants in a motor vehicle, leak tests of all system components that come in contact with a halocarbon are also required at least once every 12 months.

Refer to the Refrigerant Code of Practice for more information on acceptable leak testing methods.

A Leak Test Notice containing the information outlined in item 2 of Schedule 2 of the Federal Halocarbon Regulations, 2003 must be affixed to a system after each leak test. The Notice cannot be removed except to replace it with another notice.

Dismantling, decommissioning and destruction

Prior to dismantling, decommissioning or destroying any refrigeration or air-conditioning system, all halocarbon must be recovered into a container designed and manufactured to be refilled and to contain that specific type of refrigerant.

A Dismantling, Decommissioning and Destruction Notice containing the information outlined in item 1 of Schedule 2 of the Federal Halocarbon Regulations, 2003 must be affixed to the system. The Notice cannot be removed except to replace it with another notice.

Regulatory compliance

Environment Canada undertakes regular inspections in order to verify compliance with the requirements of the Canadian Environmental Protection Act, 1999 (CEPA 1999) and its regulations. Investigations are conducted when there are reasonable grounds to believe that a violation has occurred. In situations of non-compliance, enforcement officers may issue a warning or an environmental protection compliance order, proceed with prosecution or take some other enforcement action, depending on the circumstances (see the Compliance and Enforcement Policy for the Canadian Environmental Protection Act, 1999).

Where an officer proceeds with prosecution and a conviction is obtained, the court may order a fine and/or imprisonment. In 2012, maximum fines were increased and mandatory minimum fines were introduced for certain specified offences. For further information, consult Environment Canada’s website.
