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 home resiliency that could help protect your home and your family from environmental damages at the same time.

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

Resiliency measures to protect your home

Make your home more resilient against potential fires by:

  • Installing non-combustible or fire-resistant exterior cladding materials when insulating 80 percent to 100 percent of exterior walls (e.g. stucco, concrete and fibre cement board, metal siding and brick)
  • Installing non-combustible metal mesh covers and screens (3 mm) in gutters, eaves and vents to reduce accumulation of flammable vegetation and limit areas exposed to sparks and embers
  • Replacing existing roofing and eave projections with fire-retardant roofing materials, such as metal, asphalt, clay and composite rubber tiles with Class A UL/ASTM rating
  • Replacing existing soffits, eave projections and other roof projections with fire-retardant roofing materials, such as metal, concrete and fibre cement board
  • Replacing service opening and vents in exterior walls with fire-resistant materials

Additional resources for wildfire protection

Make your home more resilient against potential flooding or water infiltration by:

  • Installing an alarm with an additional emergency battery backup to a sump pump system
  • Installing backwater valve and alarm to prevent sewage backup during flooding
  • Installing flood alarms connected to shutoff the main house water supply valve
  • Installing flood alarms (water leak detection system)
  • Practicing landscape water management (rain water and flood control), including covering over window wells, backfilling grading away from foundations
  • Adding extended downspouts to 1.8 m
  • Installing rain screen and strapping on exterior walls (for nearly everything other than vinyl)

Explore more resources on how to protect your home from flooding through Intact Centre’s Home Flood Protection Program.

Make your home more resilient against wind damage by:

  • Adding hurricane-resistant shutters (roller shutters roll up and down) and windows (aka impact windows or coastal windows)
  • Installing window blinds and films (security or solar)
  • Installing hurricane straps or special self-tapping screws (making sure roof trusses are securely fastened to wall below)
  • Adding fasteners (screws) to roof sheathing, wall sealant, and flashing under roof shingles
  • Adding hurricane anchors between walls and foundation
  • Incorporating roof and wall fastening (re-nailing)
  • Installing sealant and flashing under roof shingles

Make your home more resilient to power failures by:

  • Adding a standby emergency battery backup-stand alone system
  • Adding a standby non-portable emergency power sources (e.g. generators)

Batteries connected to photovoltaic (PV) systems

Eligibility criteria for reimbursement:

  • Must be connected to a permanently mounted photovoltaic system;
  • Batteries can be for a new battery system, the replacement of existing batteries or to supplement an existing battery system;
  • Batteries must be rated for deep cycle (any technology);
  • Inverter and charge controller purchase and installation costs can be included as part of the battery system’s total cost; and
  • Batteries must be permanently installed (i.e. portable batteries and electric vehicles are not eligible for this grant).

Best Practices:

  • Batteries can be added to an existing PV system, or be for a newly installed PV system that also qualifies for the Canada Greener Homes Grant initiative for renewable energy systems.
  • Consider (if required or included) an inverter with true sinewave output, a minimum continuous capability of 1200 Watts (W) and a minimum surge capability of 2500 W.
  • Consider battery system with a minimum total capacity rated at 4500 Watt hours at 20 hours. To determine amp hours, divide 4500 Watt hours by the voltage of the battery. For example, for a 12 volt battery the capacity required is 375 Amp hours;
  • Inverter and charge controller should be certified to CSA C22.2 107.1, “Power conversion equipment” or CSA C22.2 62109, “Safety of power converters for use in photovoltaic power systems”.
  • Discuss maintenance, warranties and specifications with your supplier or contractor when selecting the most appropriate type and size of batteries for your specific usage.
  • The installation or inspection of a battery back-up system must be undertaken by a licenced and trained professional.
  • An electrical permit for installation of the batteries and any related equipment or work must be obtained, as required. Please note that recent changes to the Canadian Electrical Code may prohibit battery installations inside dwellings so check with your supplier, installer or local code authority.

Roofing Membrane – Self-adhering roofing underlayment applied to entire roof

Eligibility criteria for reimbursement:

  • The roofing underlayment must be self-adhering;
  • The roofing underlayment must be applied to the entire surface area of the roof that covers enclosed spaces, including attached garages; and
  • The self-adhering underlayment must be certified to ASTM D1970 / D1970M, “Standard Specification for Self-Adhering Polymer Modified Bituminous Sheet Materials Used as Steep Roofing Underlayment for Ice Dam Protection” or CSA A123.22, “Self-adhering polymer modified bituminous sheet materials used as steep roofing underlayment for ice dam protection.”

Best Practices:

  • The self-adhering underlayment should be compatible with the type of roof (e.g. some roofs such as metal ones, may require a self-adhering underlayment that withstands higher temperatures).
  • The application of a self-adhering underlayment can increase the risk of condensation forming under the roof surface. Ensure adequate roof venting is present in all types of roofs.
  • Consult your contractor to reduce the risk of moisture accumulation in the roof assembly, such as in the case of a cathedral type roof.
  • Torched on membranes and flat roofs are not eligible as a roofing membrane is already part of a standard flat roof installation.
OptionGrant amount
Roofing membrane—self-adhering roofing underlayment applied to entire roof$150

Basement Wall Waterproofing

A grant is available for waterproofing the below-grade wall sections of basements. Crawl space and slab-on-grade foundations are not eligible for this grant.

Eligibility criteria for reimbursement:

  • waterproofing must be performed on the exterior side of the below-grade basement wall with rubberized or polymer membranes (e.g. waterproof-rated spray, trowel-on, roll-on and sheet materials). Ensure that a waterproofing membrane is used and not a damp/moisture-proofing membrane.
  • a minimum 80% of the below-grade wall area must be waterproofed. This applies to all exterior facing below-grade basement walls but does not include party walls between homes (e.g. semi-detached homes).

Best Practices:

  • Waterproofing 100% of the below-grade wall area;
  • Seal all existing cracks, holes and penetrations with hydraulic sealing compounds;
  • Ensure proper drainage (i.e. air gap drainage membrane, drainage board or free draining backfill);
  • Ensure the presence of drainage tile (i.e. weeping tile or French drain), either new or existing, as long as it is in good working condition;
  • Install exterior drainage membranes to provide a drainage layer and protection to the waterproofed surface;
  • Add insulation to the exterior side of the wall when waterproofing;
  • Verify that products used are specified for waterproofing. Simple paint brush or roller applied interior sealants are considered damp/moisture-proofing membranes, and are not eligible for the waterproofing incentive as they are not rated to withstand hydrostatic pressure;
  • Review all warranties from waterproofing companies for the services rendered and products used;
  • Waterproofing is typically not considered a do-it-yourself project due to inherent risks such as excavation work. However, do-it-yourself waterproofing is acceptable but evidence of work (e.g. pictures and invoices for purchased products) performed a t various stages is required to ensure compliance with the listed requirements; and
  • If required, obtain a building permit.
OptionGrant amount
Basement wall waterproofing $875

Moisture Proofing Crawl Space Floor, Walls and Headers

All closed and vented crawl spaces are eligible for the moisture/damp-proofing grant. Crawl space moisture proofing is also known as encapsulation.

Eligibility criteria for reimbursement:

  • 100% of the floors, walls and headers of all crawl spaces must be covered by a continuous moisture barrier; for example, a minimum 6 mil polyethylene barrier on the floor and closed-cell foam on the walls and headers. Consult with your local building authority.
  • All seams, edges and penetrations in the moisture barrier must be sealed with suitable materials such as tape and caulking (check specifications with manufacturer or supplier).

Best practices:

  • All water infiltration issues need to be addressed first (e.g. existing leaks, flooding issues).
  • All issues with insect and vermin need to be addressed before starting on an encapsulation project.
  • When a crawl space is attached to a basement, the crawl space’s moisture barrier must be sealed to the basement foundation junction (e.g. floors and walls). If there is a structural or full wall between the two, with or without an access hatch, then the crawl space’s common wall must be moisture proofed as part of the 100% encapsulation;
  • Continuous moisture barrier should be of 0.75 perms (43 ng/Pa·s·m²) or less or otherwise specified in local building code. 
  • When using polyethylene, ideally choose 10 mil or thicker as it is stronger and more robust.
  • If wall and header insulation such as closed-cell foam is used as the moisture barrier it may also be eligible for the crawl space insulation grant.
  • Encapsulation can be performed by the homeowner or a contractor.
  • Review all warranties from encapsulation companies for the services rendered and the products used.
  • If a combustion appliance is located in the crawl space, verify with a heating professional that there are no issues of concern.
  • If required, obtain a building permit.
