CGAH-Canada Greener Affordable Housing (Social Housing)

Enhancing Energy Efficiency and Sustainability in Affordable Housing with Green Canada Energy Advisors

Unlock Funding for Energy Retrofits with the Canada Greener Affordable Housing Program.

The Canada Greener Affordable Housing program (CGAH) offers valuable financing opportunities for affordable housing providers. This program aims to support deep energy retrofits in existing multi-unit residential buildings, helping providers meet climate goals. With forgivable and low-interest loans available, the program assists in financing retrofit measures and activities necessary for energy efficiency improvements

Through the program, the Canada Mortgage and Housing Corporation (CMHC) provides funding of up to 100% of eligible retrofit costs, with a maximum limit of $170,000 per unit (combining low-interest repayable and forgivable loans). Forgivable loans are determined by the lesser of $85,000 per unit or 80% of eligible retrofit costs, while low-interest loans cover the remaining amount.

 Additionally, the program provides contributions for pre-retrofit activities, offering a maximum contribution of $130,000 per project.

To be eligible, the project must primarily consist of residential buildings with a minimum of 5 units or beds. Single detached dwellings, duplexes, and townhouses must be at least 10 years old, while mid- to high-rise, low-rise, and multi-plex buildings must be at least 20 years old. 

Applicants must meet affordability criteria established by municipal, provincial, territorial, Indigenous government, or CMHC programs. Other affordability criteria, such as rent-gearedto-income, low-income, moderate-income, established income, or rent limits/thresholds, may also apply.

What is Canada Greener Affordable Housing?

CGAH offers energy retrofit loans to support multi-unit (5+) affordable housing providers, including co-operatives and not-for-profit owned housing, for deep energy retrofits.

Key Highlights:

  • Deeper reductions in energy consumption and Greenhouse Gas emissions.
  • Improve building quality.
  • Adapt to climate change and extreme weather events.

To facilitate the adoption of greener building practices and ensure affordability and sustainability, The program offers vital financial assistance. This program provides the necessary support to make the transition to a more environmentally friendly building, promoting energy efficiency and reducing carbon emissions.

Understanding Deep Energy Retrofits (DER)

A Deep Energy Retrofit (DER) defined as:

  • Targeting a minimum energy savings of 50% or more of energy used onsite in a building (Energy Consumption) compared to the baseline energy usage, resulting in reduced greenhouse gas emissions.
  • Enhancing the building envelope by implementing insulation and air sealing measures to improve energy efficiency.
  • Upgrading heating, cooling, and water systems to high-efficiency systems.
  • Achieving a successful deep energy retrofit leads to improved building durability, enhanced comfort, and better indoor air quality.

Program Objectives of CGAH

The CGAH program aims to align with the Green Buildings Strategy (GBS) and contribute to Canada’s 2050 climate goals. Deep energy retrofits under the program are expected to target the following objectives:

  • Achieve a significant 70% reduction in energy consumption compared to pre-retrofit performance.
  • 80% to 100% reduction in greenhouse gas (GHG) emissions relative to pre-retrofit performance.

What is the Green Buildings
Strategy (GBS)?

The Green Buildings Strategy (GBS) is a comprehensive federal government strategy under the umbrella of the Emission Reduction Plan.

The primary objective of the GBS is to reduce greenhouse gas (GHG) emissions from the buildings sector. By 2030, the strategy sets an interim goal of achieving a 37% reduction in emissions compared to 2005 levels.

The development and implementation of the GBS are spearheaded by Natural Resources Canada (NRCan), in collaboration with other key government departments and agencies such as Environment and Climate Change Canada (ECCC), Treasury Board Secretariat (TBS), Canada Mortgage and Housing Corporation (CMHC), and various stakeholders.
