Natural Resources Canada (NRCan) is the Canadian government department responsible for monitoring and enforcing energy efficiency regulations—the regulations impose requirements on minimum energy performance levels for various energy-consuming products, label energy-consuming products, and collect energy use data.

All regulated products imported into Canada for sale or lease or transferred from the manufacturing province to another region (trans-provincial transportation) should meet the energy efficiency standards required by the energy efficiency regulations. Therefore, Natural Resources Canada requires that all regulated products must obtain an energy efficiency certification mark from a certification body accredited by the Canadian Standards Council (SCC).
