In a remote or northern community, the cheapest unit of heat is the one a home never loses. Air leakage, basements, walls and windows are where most heat escapes, so a tight, well-insulated envelope with balanced ventilation should come before any choice of furnace, boiler or heat pump. Clean energy programs can help, but several of the best-known ones are now closed or fully committed, so check status before you plan around them.
This post is general information for housing managers and technical staff, not engineering, legal or funding advice. Program rules and code adoption change, so confirm anything here with Indigenous Services Canada (ISC), CMHC, Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC), Natural Resources Canada (NRCan) and your own inspector or lands office before you act on it.
Why do heating costs hit remote and northern homes so hard?
Many remote communities are not on the grid or a gas line at all. The Canada Energy Regulator counts approximately 178 remote Indigenous and Northern communities that are not connected to the North American electricity grid or natural gas infrastructure. It says these communities generally rely on diesel fuel for electricity generation and home heating, and that the fuel is expensive to purchase and transport.
The household cost shows up in national data. Using the 2021 Census, Statistics Canada estimated that 5.6% of households in Canada were energy poor, meaning they spent 10% or more of after-tax income on home energy bills (electricity and fuel). On reserves the rate was 12.9%, more than double. Households in dwellings that needed major repairs were also far more likely to be energy poor (9.7%). In other words, the condition of the house and the cost of heating it are linked, and both land on the same family.
For a housing department, that link matters twice: high energy bills strain tenants, and a poorly performing home tends to need more repairs. Decisions made at design and purchase time set those costs for decades.
Where does the heat go in a typical home?
NRCan's long-running homeowner guide, Keeping the Heat In (now hosted on Canada.ca, page updated November 2026), gives rough shares of heat loss for a typical Canadian house:
- Air leakage: typically about 25 percent of heat loss.
- Basements: about 25 percent of a home's total heat loss, because of the large uninsulated area above and below grade.
- Walls: about 20 percent of heat loss.
- Windows, doors and skylights: up to 35 percent of total heat loss.
These shares overlap and vary from house to house, but the lesson is consistent: the envelope decides most of the heating bill. The same guide warns that tightening a house raises indoor humidity and reduces the air available to fuel-burning appliances, and that air leakage does not make for good ventilation. Its recommended approach is a ventilation system able to change all the household air about once every three hours, plus separate combustion air for fuel-burning appliances. A heat recovery ventilator (HRV), it notes, typically recovers 70 to 80 percent of the heat from exhaust air.
For an existing home, the guide recommends a professional energy evaluation: an NRCan energy advisor measures insulation and runs a blower door test for airtightness, then produces a list of recommended retrofits and an EnerGuide rating. A blower door number for each unit is a useful baseline in any housing plan, because it lets you compare homes and measure whether a retrofit worked.
What envelope features do high-performing northern homes share?
CMHC commissioned a literature review of high-performance northern multi-unit housing (published March 2019, mostly projects above 60°N in Canada, the United States, Greenland and Scandinavia). It is older and focused on multi-unit buildings, but its findings translate well into questions you can put to any designer or builder:
- Insulation well above code. Reported wall values ran roughly R28 to R71, roofs R41 to R81 and floors R26 to R63.
- Measured airtightness. One northern pilot house was designed for less than 0.6 air changes per hour at 50 Pa. Ask what airtightness a new home is designed to and whether it will be tested.
- Fewer thermal bridges. Thermal breaks at cladding attachments and fewer envelope penetrations.
- High-performance windows. Typically triple-pane, gas-filled, low-emissivity glazing with insulated frames, and smaller, fewer windows on north walls.
- Heat recovery ventilation. Heat recovery effectiveness of at least 75%, with several projects designed for 85 to 90%.
The review found these projects typically cut annualized energy use by 30% to 60%, so similar cost reductions can be expected. It also found higher upfront cost: two European examples cost roughly 15% to 20% and 19% more than reference buildings. That trade-off is the real decision for a housing committee. In a community paying for trucked, flown or barged fuel, the operating savings recur every winter for the life of the home, while the premium is paid once.
What do the National Building Code energy tiers mean for your project?
The 2020 national codes introduced energy-efficiency tiers. As Manitoba's adoption notice explains, there are five tiers for housing and small buildings under the National Building Code and four for larger buildings under the National Energy Code for Buildings. At the highest tiers, a building realizes at least a 60 per cent reduction in energy consumption over the baseline Tier 1.
Provinces choose which tier to enforce, and many start at the bottom. Manitoba adopted the 2020 editions effective January 1, 2024, starting at baseline Tier 1, with additional heat-recovery ventilation requirements for homes on top of the national rules. Saskatchewan announced in February 2025 that it would revert to Tier 1 for housing and small buildings, after earlier delaying higher tiers.
Two practical points follow. First, Tier 1 is a legal floor, not a performance target; nothing stops a First Nation from specifying a higher tier, or an airtightness target, in its own housing standards or tender documents. Second, which code applies on reserve, and who inspects, depends on your band's bylaws and your funding agreement, so confirm the requirement with ISC or CMHC and your inspector before you write a spec.
Which heating system makes sense in a diesel-reliant community?
Once the envelope is right, the heating load shrinks and the system choice gets easier. A few points from federal guidance to weigh:
- Cold-climate heat pumps. NRCan says cold-climate heat pumps work in temperatures as low as -30°C, with backup heating for the coldest days. In an off-grid community where electricity comes from diesel generators, a heat pump still draws on that diesel plant, so talk to your utility about generator capacity before switching many homes at once.
- Combustion safety in tight homes. Keeping the Heat In recommends direct-vent or sealed-combustion appliances, which use outside air, as the first defence against combustion gases spilling into the house. Heat pumps are its stated alternative.
- Servicing. The same guide says oil-fired furnaces and boilers need annual cleaning and tuning. In a fly-in or ice-road community, ask who will do that work and where parts come from before you choose equipment.
- Hydronic heat and solar. In CMHC's northern review, all but one project used hydronic (hot-water) heating, mostly baseboards and convectors, and 53% used solar thermal collectors, often supplemented in winter by electric, oil or wood heat.
There is no single right answer. The best system is the one your community can fuel, service and repair locally, sized to a home that loses little heat in the first place.
Which clean energy programs are open right now?
Status checked in November 2026. Verify again before you build a plan around any of these.
- Clean Energy for Rural and Remote Communities (CERRC), NRCan: closed to new applications. The program page (modified May 26, 2026) says it is fully committed and no longer accepting applications under any stream, and is scheduled to officially close on March 31, 2027. It funded renewable energy, related energy efficiency and capacity building to reduce fossil fuel use for heating and electricity, and has supported over 230 projects.
- Northern REACHE, CIRNAC: open, ongoing intake, but limited by region. The program page says its objective is to reduce Northern communities' reliance on diesel for heating and electricity, covers the Yukon, Northwest Territories, Nunavut, Nunavik and Labrador, accepts applications on an ongoing basis and has no deadline. The page was last modified in December 2023, so confirm with CIRNAC. Communities outside those regions are not in its stated scope.
- Indigenous Off-Diesel Initiative (IODI): no open intake shown. The first cohort's page says the application period is closed. The Cohort 2 page (modified July 2025) shows applications opened in October 2022 with Energy Champions selected in February 2023, and mentions no future cohort. Eligible communities had to be majority Indigenous and not connected to the grid or gas network.
- Wah-ila-toos, the federal single window: check before relying on it. The Wah-ila-toos page still says applications are reviewed on an ongoing basis until funding is fully allocated, but it was last updated in December 2024, before CERRC was fully committed.
- Canada Greener Affordable Housing (CGAH), CMHC: closed. The program page says it has enough applications to fully commit its budget and the portal is closed. It funded deep energy retrofits of rental housing and listed Indigenous government affordability criteria among those accepted.

How do you turn this into a housing plan decision?
- Know your fuel. Record each unit's heating fuel, its delivered cost and how it reaches the community. That sets the value of every efficiency upgrade.
- Get a baseline. Arrange energy evaluations with blower door tests on a sample of homes, starting with those needing major repairs.
- Write performance into specs. For new homes, state an energy tier or airtightness target, window performance and balanced ventilation with heat recovery, rather than accepting the provincial minimum by default.
- Choose serviceable systems. Favour heating and ventilation equipment that local staff can maintain and that suits your power supply.
- Compare life-cycle cost, not price. Put the upfront premium beside decades of fuel savings when the housing committee decides.
- Confirm program status early. Check CIRNAC, NRCan and CMHC directly, and plan as if a closed program will not reopen.
Where does a builder fit in?
A builder cannot set your energy policy, but it can build to it. Herauf Modular builds homes and community buildings as finished sections indoors in its Saskatchewan and BC plants, then delivers and sets them on site. Every unit meets or exceeds CSA A277 and the National Building Code for climate zones 6 through 8. Most builds are manufactured and delivered in about 16 weeks, with foundations, pads and services prepared on site at the same time.
Herauf has delivered to northern communities in winter, including youth transitional homes and a child and family services building for St. Theresa Point First Nation, carried roughly 1,300 km north over the winter ice road. For more on how factory building works for remote sites, see modular housing for remote communities.
If you are planning homes and want to talk through envelope and heating specifications for your climate zone, send an enquiry. Herauf replies within one business day. Herauf does not administer funding, does not apply on a community's behalf and cannot promise eligibility for any program.
