Ecoenergy
Natural Resources Canada's (NRCan's) ecoENERGY Retrofit program provides financial support to homeowners, small and medium-sized businesses, public institutions and industrial facilities to help them implement energy saving projects that reduce energy-related greenhouse gases (GHGs) and air pollution.
There was originally a residential program, and a business program. Natural Resources Canada's Office of Energy Efficiency is no longer offering the ecoENERGY Retrofit Incentive for Buildings, the commercial/institutional component of the ecoENERGY Retrofit financial incentives for existing homes, buildings and industrial processes.
The business program ended on June 6, 2012.
