The Canada Greener Homes Loan program is a government initiative designed to help Canadians make their homes more energy-efficient and reduce their carbon footprint. Under the program, homeowners can apply for loans of up to $40,000 to finance energy-efficient home improvements such as insulation, high-efficiency heating and cooling systems, and renewable energy technologies. The loans are repayable over a period of up to 15 years and are interest-free, making it an affordable option for homeowners looking to invest in energy-efficient upgrades.
