Eligible grants for my home retrofit

As part of the initiative, you have access to:

  • up to $600 for a home evaluation and expert advice so you can begin to plan your retrofits
  • up to $5,000 total to help you make energy efficiency retrofits to your home

What you can claim

1.

Your pre-and post-retrofit EnerGuide evaluations

You will be reimbursed for the cost of the pre-and post-retrofit evaluations up to a maximum of $600. Both evaluations are required under the initiative for reimbursement. You will need to complete at least one of the retrofits that is both eligible and recommended by your energy advisor in their report in order to be reimbursed. You will not be reimbursed for the pre-retrofit evaluation unless you continue through the full Greener Homes Grant process.

If you had completed an evaluation prior to December 1, 2020, but made recommended and eligible retrofits to your home on or after December 1, 2020, you can only be reimbursed for the eligible retrofits and post-retrofit evaluation.

2.

Part of your completed home retrofits

If you are eligible for the Greener Homes Grant, you could receive a total reimbursement of up to $5,000 for retrofits. You may choose to do more than one of the retrofits below but in all cases the maximum reimbursement will not exceed $5,000 total.

Special measures for northern and off-grid communities

We recognize that Canadians living in northern and off-grid communities face specific challenges when it comes to completing home retrofits, including higher equipment and labour costs.

Make your home more resilient by making additional upgrades

Climate change and its effects often hit close to home. Many environmental factors related to climate change can have an impact on your home causing fire, flooding, wind damage and loss of power. Your home and its location can help you identify your specific vulnerabilities to climate change. If you are in the process of making upgrades to your home, you should consider additional retrofits that could help protect your home and your family from environmental damages.

Insulation

The Canadian Greener Homes Grant allows homeowners to increase their home insulation. This slows the rate of heat loss, resulting in improved energy use and can help save money. The insulation’s resistance to heat flow is measured using both an RSI value and an R-value. R-value is the imperial measurement and the Résistance Système International (RSI) value is the metric measurement. The higher the resistance value, the slower the rate of heat transfer through the insulating material. Recommendations on insulation improvements and the calculation of your incentive will use these values. Read more about insulation materials.

All equipment must be purchased in Canada. Online purchases are only eligible if they are ordered from an online distributor in Canada.

Attics

Relatively easy access makes the attic a favourite starting point to insulate for many homeowners. Even if an attic is already insulated, you may be able to improve comfort and increase the energy efficiency. Learn more about insulation

Eligibility criteria for reimbursement:

  • Insulate a minimum of 20% of the total area of your attic or ceiling.
  • You must increase the insulation value (R-value or RSI).
  • Add insulation in the same location (e.g., attic floor vs. attic ceiling) as the insulation present at the time of the pre-retrofit evaluation.

Important:

  • The grant amounts reflect a situation where 100% of the ceiling area is one roof type. Your home may have a combination of ceiling types.
  • The total grant for any combination of attic, cathedral ceiling and flat roof insulation cannot exceed $1,800.
  • The total amount of your reimbursement will be calculated based on the total percentage of your attic that you choose to insulate. For example, if you insulate 80% of your attic you would qualify for 80% of the amount listed below.

Air sealing

Making improvements to reduce the air leaving your house is the single most important retrofit you can make to improve energy efficiency and it should be considered first in any retrofit strategy. Your Renovation Upgrade Report will provide you with a target to improve the airtightness of your home. The lower the value you achieve, the more favourable the grant amount. Typically, these levels would be achieved with the assistance of an air-sealing professional.

Perform professional air sealing to improve the air-tightness of your home.

Space and water heating

Furnaces are not eligible under the Canada Greener Homes Grant. The only exception is when you reside in an off-grid community, please review the information on north and off-grid communities if it applies.

Canada’s cold climate means that space heating accounts for over 60% of the energy used in the average Canadian home. Learn more about energy-efficient heating equipment

Many homes in moderate climates can rely on heat pumps to heat or cool their homes year-round. In colder climates, a cold-climate heat pump is more effective and reduces the need for a supplementary heating source. A heat pump is an electrically driven device that extracts heat from a low temperature place and delivers it to a higher temperature place. Learn more about heat pumps

A contractor or energy advisor can help with estimating the economics of heat pumps in your area and the potential savings you can achieve. Heat pumps in general can come at a higher cost compared to other heating systems due to the number of components in the system. In some regions and cases, this added cost can be recouped and significant GHG savings can be made in a relatively short period through energy cost savings. However, in other regions, varying utility rates can extend this period. Speak with your energy advisor to see if a heat pump is right for you.

The newly installed system must meet the following criteria:

Note: For central ducted systems, if part of the cold climate heat pump listed systems, the furnace or air handler must always be the specified matching unit.
$5,000

Note: The Canada Greener Homes Grant program is intended to provide grants for heat pump systems which distribute heat to the entire home, regardless of whether the system is a central ducted or ductless system. The Canada Grant  program is not intended to provide grants for heat pumps that only service a portion of the house such as one or two rooms in the house, or only a home addition. The requirement does not necessarily need to be based on peak-load heating, as this can lead to excessive cycling on/off of the system. In some cases, there may be a home design where the heat pump provides heating to the entire home during the bulk of the heating days, and then a backup supplementary heating system provides heating to the entire home below a certain cut-off temperature for very cold days.

The specific system needs to be determined in consultation with the mechanical contractor and a sizing guide tool, such as the one offered by Natural Resources Canada. The heat pump system is not typically sized to deliver 100% of the peak heating load as this could lead to an oversized system that frequently cycles on/off. Mechanical contractors should design a system that optimizes the energy savings for a house and increase the comfort of occupants. The design should account for the anticipated heat requirements based on other planned energy efficiency upgrades to the building envelope (such as insulation, windows or air sealing upgrades) in order to avoid oversizing the unit as they can have a significant impact on the heating load requirements of the house.

In the case of ductless systems (mini-split systems, multi-split systems), a minimum of two indoor head units are required and the ductless system must be sized to provide heat for the entire home. The particular combination of ductless system that is best suited to the configuration of the home would be determined with a mechanical contractor. In the case of a mini-split system with one outdoor unit and one indoor head, a minimum of two mini-split systems would need to be installed to qualify for the Grant  , because a minimum of two indoor heads is required.

It is recommended that the toolkit for air source heat pump sizing and selection be used by the mechanical contractor to determine the optimal sizing needs.

Domestic hot water equipment

Water heating accounts for over 20% of the energy used in the average Canadian home. Learn more about making the switch to a more energy-efficient water heater to save money on your energy bill and reduce your carbon footprint.

There are installation requirements that must be met as follows:

  • Must be installed by a licensed and trained professional. When using a licensed professional, it is highly recommended that you obtain proof of their licence to install equipment in your province or territory.

Resiliency measures

Climate change and its effects often hit close to home. Many environmental factors related to climate change can have an impact on your home, causing fire, flooding, wind and loss of power. Your home and its location can help you identify your specific vulnerabilities to climate change.

If you are in the process of making upgrades to your home, consider additional retrofits that could help protect your home and your family from environmental damages at the same time.

Eligibility criteria for reimbursement:

The resiliency measures detailed below must be combined with an energy efficiency retrofit from the Canadian Greener Homes Grant program.

Option Incentive amount
Batteries connected to Photovoltaic systems to provide standby power for home $1,000
Roofing membrane—self-adhering roofing underlayment applied to entire roof $150
Foundation water-proofing $875
Moisture proofing of 100% of crawlspace floor, walls and headers $600

Multi-Unit Residential Buildings (MURBs)

A low-rise MURB is a building of three or fewer storeys in height, having a building area not exceeding 600 m2, and is not a retirement home. MURBs must either be stacked (up/down) or have a common area—townhouses are not MURBs. View the full definition and eligibility details.

Eligibility criteria for reimbursement:

  • The low-rise MURB must conform with the definition set out by the Canada Greener Homes Grant
  • A single EnerGuide evaluation must be undertaken for the entire structure (or address) and not on a unit-by-unit basis.
  • Homeowners within the MURB need to organize themselves (e.g., by way of a condo board) in such a way that all homeowners are aware that the evaluation will be taking place. 
  • Retrofits in a MURB must be agreed to by the person or persons who are able to make decisions about the renovations to the building.
  • Individual homeowners within the MURB must apply for individual grants of up to $5,000 based on the single EnerGuide evaluation undertaken for the entire structure. 

Applying for reimbursement for a low-rise MURB

Individual homeowners within the low-rise MURB must apply for individual grants of up to $5,000 based on the single EnerGuide evaluation undertaken for the entire structure.
The maximum amount that a MURB structure can receive is $20,000.

Insulation and air sealing

The maximum allowable amount for building envelope measures—adding insulation and air sealing—in MURBs will be calculated based on the number of units within the building. The table below provides the multiplier amount.  

Number of dwelling units per MURB 2–3 4–6 7–9 10–12 13–16 17+
MURB Multiplier 1.0 1.5 2.0 2.5 3.0 4.0

The role of the multiplier factor is to account for larger areas to insulate or renovate when comparing a MURB to a single dwelling. Eligibility criteria for respective insulation measures remain the same as described in the list of incentive measures (for example, insulating a minimum of 20% of the total area of the attic/ceiling). As for regular homes, MURBs cannot be reimbursed for more than 100% of the costs of the renovation.

The MURB multiplier determines the maximum grant amount for the MURB’s entire building, based on the number of units.
Examples:
Maximum grant for a 3-unit building is $5000 x MURB multiplier 1 = $5,000.
Maximum grant for a 4-unit building is $5000 x MURB multiplier 1.5 = $7,500.
Maximum grant for a 15-unit building is $5000 x MURB multiplier 3 = $15,000.
Maximum grant for an 18-unit building is $5000 x MURB multiplier 4 = $20,000.

The MURB multiplier also determines the maximum number of homeowners living in the building as their primary residence that can apply in order to reach the maximum eligible grant.

Note that for low-rise MURBs that are owned by one person and of which the remaining units are rented, the owner must live within the building as their primary residence. The maximum incentive that can be given in this case is $5,000 as there is only one homeowner residing in the building.

The windows and doors grants are calculated on a rough opening basis. A rough opening is the structural framing in a wall separating a heated space from an unheated space that creates an opening for the installation of a window or door. For example, a bay window with three window units installed into one rough opening is eligible for only one grant.

The MURB multiplier does not apply to windows, doors or solar panels, but it is possible to get reimbursed for more windows, doors and solar panels through the higher grant amount applicable to the entire building. The multiplier can be applied to the grant amount for:

  • MURB insulation
  • Air sealing
  • Resiliency measures

MURBs are not eligible for:

  • Heat pumps or domestic water heaters (including in northern and off-grid communities)
  • Thermostats

Here are some examples of grant calculations:

Example 1: a MURB comprising nine units and wanting to claim amounts for both attic and exposed floor insulation would be calculated as follows:
(attic maximum $1,800 x MURB multiplier 2.0 = $3,600) + (exposed floor $350 x MURB multiplier 2.0 = $700) = $4,300. As this amount is below $5,000, it can be claimed by one homeowner or divided between two homeowners as this is a nine-unit MURB.

Example 2: a MURB comprising four units and wanting to claim amounts for three ENERGY STAR windows and exposed floor insulation would be calculated as follows:
(3 ENERGY STAR windows x $125 per rough opening = $375, no MURB grant multiplier on windows) + (exposed floor $350 x MURB multiplier 1.5 = $525) = $900. As this amount is below $5,000, it can be claimed by one homeowner or divided between two homeowners as this is a four-unit MURB.

Example 3: a MURB comprising 15 units and wanting to claim amounts for 25 ENERGY STAR most efficient windows, air sealing, basement header and air source heat pumps (ASHP) would be calculated as follows:
(25 ENERGY STAR most efficient windows x $250 per rough opening = $6250, no MURB grant multiplier on windows) + (air sealing for 10% better than target $810 x MURB multiplier 3.0 = $2,430) + (basement header $240 x MURB multiplier 3.0 = $720) + (ASHP not eligible for MURBs = $0) = $9,400. This amount must be divided and can be claimed by at least two homeowners as it is above the maximum of $5,000 for one homeowner.

Example 4: a MURB comprising 15 units and wanting to claim amounts for 20 ENERGY STAR most efficient windows, air sealing and insulation of 100% of the exterior wall area (more than R-20) would be calculated as follows:
(20 ENERGY STAR most efficient windows x $250 per rough opening = $5,000, no grant multiplier) + (air sealing maximum $1,000 x 3.0 = $3,000) + (exterior wall insulation $5000 x 3.0 = $15,000) = $23,000 that will be capped at $15,000 based on the number of units (15) and the multiplier. In this case, the amount would need to be divided and claimed by three homeowners.

Example 5: a MURB comprising eight units and wanting to claim amounts for a 13 kW photovoltaic system would be calculated as follows:
(13 kW Photovoltaic system x $1000 = $13,000, no grant multiplier on photovoltaic systems) that will be capped at $10,000 as this is based on a maximum incentive of $5000 x MURB multiplier 2.0 = $10,000. As this amount is above $5,000, it will need to be claimed by two homeowners for this is an eight-unit MURB.
