Canada is committed to energy efficiency as part of its national Green Plan, which addresses the environmental issues of climate change, and reducing energy consumption. However, lacking a national housing strategy, and with social housing provision responsibility downloaded to provinces and municipalities, home energy efficiency policies have not been well regulated nor have they been widely implemented. As such, many buildings are operating at 50% below their efficiency potential. Social housing in Canada makes up less than 6% of the housing stock, and the majority of it is between 20 and 50 years old, and is very energy inefficient. Unfortunately, most social housing providers do not enjoy the financial freedom to make costly energy efficient retrofits, which could add between a 5-10% increase to overall renovation costs.
