Natural Resources Canada's (NRCan's) Office of Energy Efficiency (OEE) promotes the international ENERGY STAR symbol in Canada and monitors its use. Major manufacturers and retailers of energy-efficient products, utilities and energy retailers, and interest groups from Australia to Europe recognized the benefits of ENERGY STAR to consumers and have joined in promoting the symbol.

ENERGY STAR is the international symbol of premium energy efficiency. Products that display the ENERGY STAR symbol have been tested according to prescribed procedures and have been found to meet or exceed higher energy efficiency levels without compromising performance.

Participation in Canada's ENERGY STAR High-Efficiency Initiative

The ENERGY STAR symbol already appears on many products sold in Canada, including major household appliances, consumer electronics, computers and other types of office equipment and heating and cooling systems. Many Canadian consumers are familiar with the ENERGY STAR symbol, having seen it on numerous products, their packaging, in product literature and advertising. To enrol as an ENERGY STAR Participant, companies must demonstrate that at least one of their products meets ENERGY STAR's strict technical specifications.

There are many advantages to registering with the program, including the potential to gain a marketing edge over the competition. The ENERGY STAR high-efficiency initiative in Canada also aims to engage other participants, such as provincial/territorial and municipal governments, utilities, distributors, retailers, procurement officials and interest groups. Working together, these diverse stakeholders can help Canadian businesses and consumers save money and contribute to Canada's climate change objectives through increased energy efficiency.

NRCan's OEE administers ENERGY STAR in Canada. In addition to enrolling participants in the program (if they are not already enrolled in the United States), the OEEpromotes and monitors the use of the ENERGY STAR symbol across Canada.
