Microwave ovens – May 2016

Technical bulletin on developing the standard

Webinar - June 2016

On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to introduce and align Canada’s EnergyEfficiency Regulations (the Regulations) for microwave ovens with standards in the United States. This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for microwave ovens.

Input received during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.


Microwave ovens are not regulated products in Canada.  In June 2013, the United States Department of Energy (U.S. DOE) issued a final rule, which established energy conservation standards for microwave ovens for standby mode and off mode. The effective date for compliance with the standards for microwave ovens is June 17, 2016.

Natural Resources Canada (NRCan) is proposing to amend the Regulations and to adopt the U.S. levels and standards pertaining to the energy performance of microwave ovens. If implemented, this proposal would ensure the Regulations for microwave ovens are aligned with those of the U.S. DOE.

Product description

A microwave oven is a household kitchen cooking appliance consisting of a compartment designed to cook or heat food by means of microwave energy, including microwave ovens with or without thermal elements designed for surface browning of food and convection microwave ovens.

Energy performance test procedure

NRCan is proposing that

  • CSA/C388-15 - Energy performance and capacity measurement of household microwave ovens is referenced as the energy performance test procedure; or
  • the product can be tested in accordance with the United States Code of Federal Regulations (CFR) Title 10 Part 430(3.2.4), Subpart B, Appendix I.

The test procedure can be ordered from:
Canadian Standards Association (CSA)
Telephone: 1-800-463-6727
In Toronto, call 416-747-4000

CSA energy efficiency standards are also available at no cost on their website. To access free standards you will first need to create an account to join the CSA Communities of Interest.

Energy performance standard

Proposed MEPS for microwave ovens are as found in CFR Title 10, Part 430.32 (j)(3):

Proposed MEPS for microwave ovens
Product type Maximum standby power (watts)
Microwave-only ovens and countertop convection microwave ovens 1.0
Built-in and over-the-range convection microwave ovens 2.2

Effective date

These Regulations will come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan proposes that the new standards will apply to microwave ovens that have been manufactured on or after June 17, 2016.

Labelling requirements

NRCan is not proposing labelling requirements for microwave ovens.

Verification requirements

NRCan proposes that these products carry a third party verification mark indicating that the product meets the MEPS and that information to be reported has been verified.

The verification mark is the mark of a Standards Council of Canada accredited certification body that operates an energy efficiency certification program for the product.

Reporting requirements

Energy efficiency reports

The energy efficiency report required for microwave ovens will include the following product specific information:

  • name of product (i.e. microwave ovens)
  • brand name
  • model number
  • name of the manufacturer
  • name of the certification body whose verification mark will be affixed to the product
  • type
  • standby power in watts

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.

Import reports

A dealer who imports these products into Canada must include the following information on the customs release document:

  • name of product
  • model number
  • brand name
  • address of the dealer importing the product
  • purpose for which the product is being imported (i.e. for sale or lease in Canada without modification; for sale or lease in Canada after modification to comply with energy efficiency standards; or for use as a component in a product being exported from Canada)

Comments invited

The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for microwave ovens.   

NRCN is specifically interested in getting feedback on:

  • energy performance standards and effective date
  • reporting requirements
  • direct reference to U.S. DOE test procedure and MEPS

Additional information on Canada’s Energy Efficiency Regulations including a current list of Standards Council of Canada accredited certification bodies can be found in the Department’s website.
