Canada's Energy Efficiency Act authorises the introduction of minimum energy efficiency standards to phase out less efficient energy-using equipment and household appliances from the Canadian marketplace. The first regulations under the Act came into force on 3 February 1995. To date, regulations have been established for more than 30 products, including residential energy-using products, electric motors and lighting products. Regulations apply to products that account for over 80% of residential energy demand. Federal regulations, which generally parallel regulations in the US, apply to imported products and products traded between provinces. Provincial regulations -- implemented in Ontario (1988), British Columbia (1990), Quebec (1992), Nova Scotia (1991) and New Brunswick (1995) -- apply to intra-provincial sales or leases.
