What federal rebates are available for insulation in New Brunswick? | Insulation IQ?

Federal insulation rebates for New Brunswick homeowners come through two primary channels: the Canada Greener Homes Grant and the Canada Greener Homes Loan, both administered by Natural Resources Canada. These programs have evolved significantly since their launch, so it's important to understand the current state of each before planning a project.

The Canada Greener Homes Grant provided up to $5,600 in grants per home for eligible energy efficiency retrofits, including insulation, windows, heat pumps, and air sealing. As of early 2024, new applications to the grant stream were closed as the program's original funding was exhausted ahead of schedule — a reflection of how heavily it was subscribed across the country. However, the federal government has signalled ongoing commitment to residential energy efficiency programming, and replacement or successor programs may be announced. New Brunswick homeowners who applied before the cutoff and completed work within the eligibility window are still receiving their payments.

The Canada Greener Homes Loan remains active as of early 2026 and offers interest-free financing of up to $40,000 for eligible retrofits, repayable over ten years. This is not a grant — you repay the full amount — but the interest-free nature effectively reduces the cost of borrowing for major insulation projects. A homeowner in Saint John doing a comprehensive envelope upgrade costing $25,000 could finance the entire project at zero interest, paying it down through the energy savings themselves. Eligibility requires a pre and post-retrofit EnerGuide home evaluation by a registered energy advisor, which is required in both cases.

For insulation specifically, eligible measures under federal programs typically include: attic and ceiling insulation (bringing performance up to R-60 or higher), wall insulation (adding continuous exterior insulation or upgrading existing cavity insulation), basement and crawl space insulation, exposed floor insulation, and air sealing work done in conjunction with insulation improvements. The key requirement is that improvements must result in a meaningful improvement to the EnerGuide rating of the home — minor top-up jobs that barely move the needle may not qualify.

The pre-retrofit EnerGuide evaluation costs approximately $400 to $600 in New Brunswick and is a prerequisite for both programs. This cost is partially offset by a rebate of $600 available through the federal programs (or was under the grant structure — confirm current terms). The evaluation is done by a Natural Resources Canada-registered energy advisor and results in a detailed report showing your home's current performance and projected improvements from various retrofit measures. This report also satisfies the NB Power requirement for their provincial rebates, meaning you can pursue both programs from a single evaluation.

Stacking federal and provincial rebates is permitted and is exactly what savvy homeowners across Moncton, Fredericton, and Saint John are doing. A major attic and basement insulation project might yield $2,000 to $3,500 in NB Power rebates and access to a $40,000 interest-free loan through the federal program. Used together, these programs can bring the effective upfront cost of a major retrofit down to a level where energy savings genuinely cover the repayment.

Indigenous homeowners and those in lower-income brackets may also qualify for additional federal support through the Canada Greener Homes for Indigenous Communities stream or the Oil to Heat Pump Affordability Program, which can provide deeper subsidies for fuel-switching combined with envelope improvements.

The most reliable current information is available directly from the Natural Resources Canada Greener Homes website (nrcan.gc.ca/greener-homes) and through registered energy advisors operating in New Brunswick.
