Metal halide lamp ballasts

July 2022

Technical bulletin on amending the standards

On April 1, 2022, the Office of Energy Efficiency at Natural Resources Canada (NRCan) updated its Forward Regulatory Plan which identifies its intention to amend Canada’s Energy Efficiency Regulations (the Regulations) to align metal halide lamp ballasts (MHLBs) with testing 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 MHLBs.

Input received during this stage of the process will inform the development of the next amendments considered. In addition, NRCan will undertake a cost-benefit analysis using the best available Canadian market data to assess the economic and environmental impacts of these new and updated standards and to ensure Canadian consumers and businesses benefit from their implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I, in 2023.


In Canada, MHLBs manufactured as of February 10, 2017, are subject to the Regulations.

MHLBs contribute to the total energy consumption of commercial and industrial buildings. The energy efficiency standards for MHLBs save energy and reduce energy costs for Canadians. The efficiency standards also reduce energy-related greenhouse gas emissions and help encourage manufacturers to adopt efficient product designs.

In 2018, the Memorandum of Understanding between the Treasury Board of Canada Secretariat and the United States Office of Information and Regulatory Affairs Regarding the Canada–United States Regulatory Cooperation Council was signed to move forward on energy efficiency and foster alignment of federal regulations where feasible and appropriate. In 2021, NRCan and the United States Department of Energy (U.S. DOE) signed the Memorandum of Understanding Between the Department of Natural Resources of Canada and the Department of Energy of the United States of America Concerning Cooperation on Energy, which acknowledges that both countries will collaborate on new and updated energy efficiency and testing standards where feasible and appropriate.

On July 14, 2021, the U.S. DOE published a notice of a proposed rulemaking pertaining to MHLBs, which updated the testing standard (86 FR 37069).

NRCan is considering amending the Regulations to align with the testing standards of the U.S. DOE. 

Product description

Metal halide lamp ballast is defined in the Regulations as a device that is used to obtain the voltage, current, and waveform necessary for starting and operating a metal halide lamp that has a nominal power of at least 50 W but not more than 1 000 W. It does not include any of the following:

  1. a magnetic-regulated lamp ballast;
  2. a replacement metal halide lamp ballast; or
  3. an electronic ballast that is designed for a nominal voltage of 480 V or to operate a lamp at an output frequency of 1000 Hz or more.

Testing standard

NRCan is considering providing more testing options by referencing the following testing standard, using an ambulatory incorporation by reference:

Energy efficiency standard

NRCan is not considering any changes for the energy efficiency standard for MHLBs.  

Important dates

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

Labelling requirements

NRCan is not considering labelling requirements for MHLBs at this time.

Verification requirements

NRCan is not considering any changes for the verification requirements for MHLBs.

These products will continue to carry a third party verification mark indicating that the product meets the energy efficiency standard and that the 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 report

NRCan is not considering any changes to the energy efficiency report requirements for MHLBs.

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 inter-provincially for the first time.

Import report

There is no change being considered in regard to import reporting.

Comments invited

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

It is important to NRCan that we engage the public and stakeholders on amendments to the Energy Efficiency Regulations. If you are aware of any dealer, manufacturer, importer, retailer, utility provider, small business, consumer group, organization, or representative of a specific group(s) of the population (including, but not limited to, women, 2SLGBTQQIA+ people, persons with disabilities, visible minorities, socio-economic status, residency, housing status, etc.), Indigenous peoples/communities, and/or other person or group that may be interested in participating in the amendment discussion and/or may be negatively impacted by this proposal, please forward them or the representative this bulletin. Please email to be added to the email distribution list (emails are used to notify stakeholders of upcoming amendments, technical bulletins, webinar registrations, and official publication in the Canada Gazette).

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

We welcome your comments by September 15, 2022. All correspondence should be forwarded to:
