What a Furnace Costs in Canada — By Province and Heating Climate
Two numbers decide this, and only one of them is the price of the box. C$4,500–C$8,500 installed in British Columbia against C$3,200–C$6,500 in Manitoba and Saskatchewan is the provincial spread. The other number is your climate: 3,520 heating degree-days in Toronto against 5,670 in Winnipeg, which is what a high-efficiency furnace is actually bought for. This calculator takes both as inputs, in Canadian dollars.
Educational calculators — always consult a licensed professional before making financial decisions.
Your furnace
Pick the climate by your city, not your province: Thunder Bay is in Ontario but sits at 5,650 degree-days, which is Prairie.
It sets the installed cost band, the HVAC mechanic's wage, and which rebates exist.
Installed C$4,200–C$7,500 · HVAC wage median C$37.00/hr
A separate question from the province — and the one that decides what a high-efficiency furnace is actually worth.
3,520 HDD18 (Toronto (City Hall)) · zone range 3,460–5,080
Size comes from a CSA F280 heat-loss calculation, not floor area. It is ignored for a heat pump, which has no published Canadian size ladder.
Gas furnace, electric furnace, or a cold-climate heat pump.
Priced from your province's own published band
An input, not something this calculator works out for you — and that is deliberate.
Mid-range C$4,500–C$5,500 · premium C$5,500–C$7,000
The two columns the by-size ladder is actually published in.
The publisher's own mid column — the ordinary replacement
Gas furnaces only. The old furnace's AFUE is on the rating plate inside the cabinet door; white plastic venting means it is already condensing.
This drives both the extra you pay and the fuel you save — and one province's rebate turns on it.
Installed C$4,500–C$6,000
This is the other half of the saving — and most people underestimate it.
Removes 16.7% of the gas the old furnace burns
The distance premium applies to the equipment and installation, never to ductwork. Duct footage and material count only if you chose modification.
The publisher stated this one as a percentage, which is why it is applied as one.
The published baseline
The line that most often turns a C$6,000 job into a C$12,000 one.
Adds nothing
Used only when you chose modification above.
Doubles the per-foot rate, so it is worth asking the contractor.
C$30–C$45 per linear foot — trunks, plenums, mains
Installed cost · Ontario · Central — Great Lakes & St. Lawrence
C$4,700 – C$8,000
All figures in Canadian dollars (CAD), BEFORE GST, HST and PST. Midpoint C$6,350.
Where that band comes from — and the one multiplication in it
The starting level is a published Canadian band in Canadian dollars, not a national average scaled to your province: C$4,200–C$7,500 for Ontario (Toronto, Ottawa, Hamilton), whose published driver is “higher gta labour rates”.
The size and efficiency lines are differences between two rows of one publisher's own table — measured from its 80,000 BTU mid-range row and its 95% AFUE row — rather than a ratio borrowed from one source and applied to another's level. That distinction is not pedantry: a Canadian pricing sweep run for this build found two Canadian retailers in the same province in the same week quoting tier spreads of 1.19 times and 1.02 times, so there is no single Canadian tier ratio to ship. The location premium is a multiplication, and only because the publisher stated its method as a percentage over a major-metro baseline.
One assumption stated plainly: the size line and the efficiency line are added together, which assumes they are independent. That publisher prints them as two separate ladders and publishes no joint table, so independence is this calculator's assumption and not the publisher's claim. Both raw ladders are on the page below so you can see the inputs and not only the answer.
Your heating climate — 3,520 degree-days
Toronto (City Hall) sits at 3,520 heating degree-days below 18 °C, which is the reference point for every figure on this page. The corridor most Canadians live in, and a wider band than people expect: Hamilton 3,460, Toronto 3,520, London 3,900, Montréal 4,200, Ottawa 4,440, Québec City 5,080. Québec City is colder than Halifax and colder than Calgary.
What the climate does not do here is change the installed cost. No Canadian source prices a furnace installation by climate, and inventing a cold-weather install premium would be exactly the fabrication avoided everywhere else on this page. The climate changes the fuel side, below.
What the efficiency upgrade actually saves
Going from 80% to 96% AFUE in this climate saves about 400 cubic metres of gas a year. The basis is Enbridge's own published typical residential customer — 2,400 m³ a year, an Ontario figure — scaled by the ratio of your climate's degree-days to Toronto (City Hall)'s 3,520, giving 2,400 m³ a year burnt here, then multiplied by the share the efficiency step removes.
Priced at Enbridge Gas's Rate 1 for its EGD zone, effective 1 July 2026 — gas supply 9.0498¢ plus first-block delivery 14.3745¢, so 23.4243¢ a cubic metre — that is C$93.70 a year.
The efficiency tier itself costs C$500 more than the 95% baseline, so it repays itself in about 5.34 years on gas alone. Two caveats that cut opposite ways: Enbridge's C$27.69 a month customer charge is payable whatever you burn and is not part of this saving, and a colder-than-1990 winter or a higher future gas price shortens the payback.
Ontario is not even one rate. Enbridge's own Union South zone published a materially different gas supply charge on the very same date, so this figure is the EGD zone's and is labelled as the EGD zone's.
Provincial rebate — Ontario
Nothing is deducted. No confirmed natural gas FURNACE rebate was found for Ontario with an amount published by the programme's own body. Saskatchewan is the only province where one was: SaskEnergy pays C$325 at 97% AFUE or better. In Ontario specifically there is no gas furnace measure in either stream of the live Home Renovation Savings Program — the C$250 Enbridge furnace rebate still circulating belonged to the earlier Home Efficiency Rebate, which is closed.
Four large programmes people still ask about are closed, and it is worth knowing which: Enbridge's Home Efficiency Rebate Plus closed to new applicants on 5 February 2024, the federal Canada Greener Homes Grant on 27 February 2024, NRCan's Oil to Heat Pump Affordability intake on 31 July 2026, and SaskPower's Home Efficiency Retrofit Rebate in April 2026. A rebate you have heard of being gone is more useful than its silent absence.
The labour behind the provincial spread
Job Bank publishes HVAC mechanic wages under NOC 72402, updated 19 November 2025. In Ontario the band is C$21.00 to C$58.00 an hour, median C$37.00 — and that is the federal wage report, not a contractor's billing rate, which carries overhead, vehicle, insurance and margin on top. It is shown as the reason the provincial installed bands differ, not as a line item: no Canadian source publishes the labour hours in a furnace changeout, so none is invented here. For context, the one city-level Canadian band read with a date is Toronto at C$4,300–C$7,000 for a standard residential replacement, with C$500–C$2,500 added for a complex install (HVAC Trust, last updated 2026-05-20).
Every figure above is in Canadian dollars and is BEFORE tax. GST, HST and PST are not modelled. The installed bands come from Canadian commercial publishers rather than a Canadian authority, and that is said rather than dressed up: no Canadian government body and no Canadian industry association publishes furnace installed cost — HRAI publishes none at all, and Enbridge, FortisBC, Hydro-Québec, BC Hydro, SaskEnergy and ATCO publish rebates, not costs. The degree-day figures are a 1961–1990 historical normal, not current climate. Estimate only; get written quotes from licensed Canadian HVAC contractors and have a CSA F280 heat-loss calculation done rather than sizing from floor area. Yukon, the Northwest Territories and Nunavut are not selectable. Job Bank publishes no HVAC-mechanic wage band for any of the three under NOC 72402, and the regional installed-cost table gives the territories no figure. Whitehorse at 6,580 heating degree-days, Yellowknife at 8,170 and Iqaluit at 9,980 are all colder than anywhere in the Prairie zone, so reusing a southern band there would understate both the equipment and the freight.
Pricing the rest of the mechanical work? The Canadian water heater rent-vs-buy calculator prices the other appliance in the same room, including the rental buyout schedule, the Canadian home renovation cost calculator covers the wider job in CAD, and the Canadian HELOC calculator shows what is borrowable against the house under Canadian lending limits if the furnace failed in January and the money has to come from somewhere.
Your Saved Scenarios
No saved scenarios yet
Why a Canadian furnace calculator is not an American one with a different currency symbol
The obvious answer is labour, and it is true as far as it goes: Job Bank publishes HVAC mechanic wages under NOC 72402 with a median of C$29.76 an hour in New Brunswick and C$40.00 in Alberta, Saskatchewan and British Columbia, and the provincial installed bands move with it. But that is a difference of degree, and a currency relabel could fake it.
The difference of kind is the climate. Populated Canada runs from 2,825 heating degree-days in Vancouver to 5,670 in Winnipeg — a factor of two on the quantity that decides what an efficiency upgrade is worth. Enbridge publishes a typical residential customer at 2,400 cubic metres of gas a year, which is an Ontario figure. Scale it to Winnipeg's degree-days and the same household burns about 3,866 m³. Replace a 78% furnace with a 98% one and you remove 20/98 of that — about 789 m³ a year. The same swap in Toronto, 80% to 96%, removes about 400 m³. No US degree-day table covers Winnipeg, and no US price covers a Canadian HVAC mechanic, so a US model here is wrong rather than merely mislabelled.
And the third difference is money going the other way. Canadian furnace rebates are provincial utility programmes, and there are far fewer than the comparison sites suggest — exactly one province has a confirmed gas furnace rebate at all. That section is below, with the closed programmes named rather than silently absent.
The provincial bands, in C$ installed
These are published levels in Canadian dollars, not a national average scaled to a province, and two rows share a band because the publisher publishes them as one region: Manitoba and Saskatchewan are one published region, and so are the four Atlantic provinces. Inventing separate bands for them to look more precise would be the province-splitting this whole route avoids. Their Job Bank wage bands are published per province and do differ, so those are not shared.
| Province | Installed, gas furnace (CAD) | HVAC wage, median (CAD/hr) | Published region |
|---|---|---|---|
| Alberta | C$3,800–C$7,000 | C$40.00 | Alberta (Calgary, Edmonton) |
| British Columbia | C$4,500–C$8,500 | C$40.00 | British Columbia (Vancouver, Victoria) |
| Manitoba | C$3,200–C$6,500 | C$36.07 | Manitoba & Saskatchewan (published as one region) |

| Nova Scotia | C$3,800–C$7,200 | C$30.84 | Atlantic provinces (published as one region) |
| Ontario | C$4,200–C$7,500 | C$37.00 | Ontario (Toronto, Ottawa, Hamilton) |
| Prince Edward Island | C$3,800–C$7,200 | C$31.21 | Atlantic provinces (published as one region) |
| Quebec | C$3,500–C$6,800 | C$38.00 | Quebec (Montreal, Quebec City) |
| Saskatchewan | C$3,200–C$6,500 | C$40.00 | Manitoba & Saskatchewan (published as one region) |
Installed bands: FurnacePrices.com's regional table, updated 2026-08-10, read 2026-09-11. A Canadian commercial lead-generation publisher, not an authority, and that is stated rather than dressed up — no Canadian government body and no Canadian industry association publishes furnace installed cost. Wages: Job Bank, Government of Canada, NOC 72402 (occupation id 7516), wages updated 2025-11-19, reference period 2023–2024. All figures Canadian dollars, before GST/HST/PST. Yukon, the Northwest Territories and Nunavut are not selectable. Job Bank publishes no HVAC-mechanic wage band for any of the three under NOC 72402, and the regional installed-cost table gives the territories no figure. Whitehorse at 6,580 heating degree-days, Yellowknife at 8,170 and Iqaluit at 9,980 are all colder than anywhere in the Prairie zone, so reusing a southern band there would understate both the equipment and the freight.
Your heating climate, city by city
The calculator asks for a zone, but pick it by looking at your own city here rather than by trusting a four-way bucket — and note how badly province and climate line up. Thunder Bay is in Ontario and sits at 5,650 degree-days, which is Prairie. Québec City at 5,080 is colder than both Halifax and Calgary. That mismatch is exactly why the zone is a separate input from the province and not derived from it.

British Columbia's figures come from the BC Building Code's own Appendix C Table C-2, the only Canadian jurisdiction publishing its code's full climatic design table free online, credited to the Meteorological Service of Canada. The rest come from NAIMA Canada's compilation of the provincial codes, which is labelled as a compilation — Codes Canada supplies the national table on request only and it could not be read on 2026-09-11, which is also why no January design temperature is published here for any city outside BC. Every row is a published figure, never an interpolation. And one limitation stated rather than buried: these degree-days are computed day by day for 1,030 Canadian stations over 1961–1990 and interpolated from analysed maps. They are a historical normal, not current climate, and the 2025 National Building Code's new forward-looking climate data does not cover degree-days.
The two published ladders, so you can see the inputs and not only the answer
The calculator builds its band from a published provincial level plus size-and-tier and efficiency differences taken inside one publisher's own table — never a ratio borrowed from one source and applied to another's level. A Canadian pricing sweep run for this sprint found two Canadian retailers in the same province in the same week quoting tier spreads of 1.19 times and 1.02 times, so there is no single Canadian tier ratio to ship. Here are the two ladders the differences come from. The 80,000 BTU mid-range row is the reference the size difference is measured from, and the 95% AFUE row is the reference the efficiency difference is measured from — which is why an ordinary mid-size mid-grade replacement reports your province's published level unmodified.
| Size | Mid-range (CAD) | Premium (CAD) |
|---|---|---|
| 40,000 BTU | C$3,500–C$4,500 | C$4,500–C$5,500 |
| 60,000 BTU | C$4,000–C$5,000 | C$5,000–C$6,500 |
| 80,000 BTU | C$4,500–C$5,500 | C$5,500–C$7,000 |
| 100,000 BTU or more | C$5,000–C$6,500 | C$6,500–C$8,000 |
| Efficiency | Installed (CAD) | Step over 95% (CAD) |
|---|---|---|
| 95% AFUE | C$4,000–C$5,500 | baseline |
| 96% AFUE | C$4,500–C$6,000 | +C$500–C$500 |
| 97% AFUE | C$5,000–C$6,500 | +C$1,000–C$1,000 |
| 98%+ AFUE | C$5,500–C$8,000 | +C$1,500–C$2,500 |
Both ladders: FurnacePrices.ca, last updated 2026-04-22, read 2026-09-11, Canadian dollars installed. One assumption stated plainly — the calculator adds the size difference and the efficiency difference, which assumes they are independent. That publisher prints them as two separate ladders and publishes no joint table, so independence is this calculator's assumption, not the publisher's claim. Both raw ladders are here so the composition is inspectable. The only city-level Canadian band read with a verifiable date is Toronto: C$4,300–C$7,000 standard, plus C$500–C$2,500 for a complex install (HVAC Trust, last updated 2026-05-20). A ten-province city table from another publisher was declined outright: it carries no publication date and its own illustration is dated 2020-03.
The rebates — one province has a gas furnace rebate, and that is all
Checked 2026-09-11 at each programme's own page, never at a comparison site. Open with a body-published amount:
- SK — Residential Equipment Replacement Rebate (SaskEnergy): up to C$325. 97% AFUE or better. Replacement of existing equipment only, installed by a SaskEnergy Network Member or a TSASK-licensed contractor, applications within 120 days of installation.
- ON — Home Renovation Savings Program (Save on Energy (IESO) and Enbridge Gas): up to C$7,500. Up to C$7,500 (C$1,250 per ton) for a cold-climate air source heat pump where the home's primary heating is electricity, oil, propane or wood — but only up to C$2,000 (C$500 per ton) where it is natural gas. Equipment must be an active model on NRCan's qualified products list. Note that the programme's heat-pump page states contractor registrations are currently paused.
- MB — Air source heat pump rebate (Efficiency Manitoba): up to C$2,000. Centrally-ducted cold-climate air source heat pump. Must supplement an electric-resistance or natural gas system; primary residence; registered contractor; within 90 days of installation; cannot replace an existing heat pump.
- MB — Air source heat pump rebate (Efficiency Manitoba): up to C$1,500. Ductless cold-climate air source heat pump, on the same conditions as the ducted rebate.
- BC — Renovating your heating system (BC Hydro): up to C$4,000. Whole-home heating; C$1,500 for partial. The heat pump must replace a PRIMARY ALL-ELECTRIC system — electric baseboards or an electric forced-air furnace — so a reader replacing a gas furnace does not qualify. Self-install ineligible. A bonus of up to C$1,000 applies to installations completed, invoiced and paid 2026-08-01 to 2026-10-31.
- QC — LogisVert (Hydro-Québec): paid per unit of capacity rather than as a flat amount, so this calculator publishes the rate instead of computing an amount. Paid per capacity rather than as a flat amount: C$50 per 1,000 BTU/h at −8 °C, or C$120 per 1,000 BTU/h if the unit is cold-climate classified. ENERGY STAR certified, installed on or after 2025-11-26, with a 5% bonus for combining measures. Because it is capacity-based and this calculator takes furnace size rather than heat-pump tonnage, the amount is NOT computed here — the rate is published instead so a reader can apply it to their own quoted capacity.
Note what that list does and does not contain. Exactly one of those applies to a gas furnace — SaskEnergy's C$325, and only at 97% AFUE or better, which is why this calculator refuses to credit it to a 95% or 96% build. Everything else on the list is a heat-pump programme, and the eligibility is where the headline numbers usually disappear: Ontario's C$7,500 falls to C$2,000 where the home's primary heating is natural gas, and BC Hydro's C$4,000 requires the heat pump to replace a primary all-electric system, so a gas-furnace household does not qualify at all.
And the programmes checked and not modelled, with the reason — because a reader who has heard of a rebate is better served by being told it closed than by its silent absence:
- A high-efficiency natural gas FURNACE rebate in Ontario — there is none. Ontario's live Home Renovation Savings Program covers heat pumps, insulation, windows, air sealing and a heat-pump water heater, and carries no gas furnace measure in either of its streams. The C$250 Enbridge furnace rebate that still circulates belonged to the earlier Home Efficiency Rebate.
- Enbridge Gas Home Efficiency Rebate Plus — CLOSED. New applicant intake closed 2024-02-05; final submission was 2025-12-31.
- Canada Greener Homes Grant — CLOSED to new applications since 2024-02-27; final documents were due 2025-12-31.
- Oil to Heat Pump Affordability (NRCan) — application intake CLOSED as of 2026-07-31, with final receipts due 2027-01-31. Up to C$10,000 for income-tested oil-heated homes on an integrated grid. Not modelled because intake has closed; the reported enhanced C$15,000 co-delivery amount and a C$250 one-time payment do not appear on NRCan's own page and are not published here.
- Hydro-Québec LogisVert geothermal — Hydro-Québec's residential page states C$250 per 1,000 BTU/h with a C$18,000 cap while its installer guide states C$750 with a C$54,000 cap. Two figures from the same utility, so geothermal is not modelled on this route rather than one of them being picked.
- Efficiency Nova Scotia — all three of its heating-rebate pages returned title-only markup on 2026-09-11 (JavaScript-rendered), so no Nova Scotia amount is published here. Its Heating System Rebates Program is reported to have closed 2025-12-31 with a mandatory home energy assessment required from 2026-01-01, but that could not be confirmed at source.
- Efficiency Manitoba natural gas furnace rebate — no amount could be found on an Efficiency Manitoba page. Its heat-pump amounts above are confirmed; a furnace amount is not.
- SaskPower — no residential heat pump or furnace rebate found. Its Home Efficiency Retrofit Rebate is reported to have ended April 2026.
Where the dollar savings stop, and why that is the honest answer
The gas saving on this route is priced in Canadian dollars for Ontario only, at Enbridge Gas's Rate 1 for its EGD zone, effective 2026-07-01: gas supply 9.0498¢ plus first-block delivery 14.3745¢, so 23.4243¢ a cubic metre, with a C$27.69 monthly customer charge payable whatever you burn.
Ontario is not even one rate — Enbridge's own Union South zone published a materially different gas supply charge on the very same date. So one Ontario rate certainly cannot stand in for Alberta's or Manitoba's, and outside Ontario this calculator reports the saving as a volume in cubic metres and leaves the dollar line absent with the reason on screen. The consequence is deliberate: a Manitoba reader gets the largest saving volume this calculator produces — around 789 m³ a year going from 78% to 98% AFUE in the Prairie climate — and no dollar figure to go with it. Multiply it by the rate on your own bill.
Heat pumps get the same treatment for a different reason. No Canadian source read publishes a seasonal coefficient of performance for a cold-climate heat pump at a named Canadian degree-day, so selecting one returns a capital cost and a rebate with no fuel saving at all — and a US HSPF rating has not been converted to fill the gap. A gas-versus-heat-pump running-cost comparison in a Canadian winter, built on a US efficiency rating, would be a guess with a decimal point on it.

The table's own note records that degree-days were computed day by day for 1,030 Canadian stations over 1961–1990 and interpolated from analysed maps — a HISTORICAL normal, which is why nothing here claims current climate data.
- Rate 1 residential — system rate change notice, EGD zone — Enbridge Gas (OEB-approved). Read 2026-09-11. Effective 2026-07-01.Total effective gas supply 9.0498¢/m³; delivery 14.3745¢/m³ on the first 30 m³. Customer charge C$27.69/month. AND THE FIGURE THIS DATASET LEANS ON MOST: Enbridge states a TYPICAL RESIDENTIAL CUSTOMER USES 2,400 m³ A YEAR. That published figure is what makes an efficiency saving derivable at all. The Union South zone differs materially on the same date (total effective gas supply 16.9580¢/m³).
- Ductwork Installation Cost — Can Do Duct Cleaning. Read 2026-09-11. Published 2026-04-06.Explicitly CAD. Full replacement in a typical single-family home C$4,500–C$7,500; flexible duct C$15–C$25 per linear foot; galvanized steel C$30–C$45 per linear foot; labour C$90–C$150 an hour. A duct-cleaning contractor, so trade-informed rather than authoritative, and labelled as such. No Canadian source read publishes a per-register or per-run duct cost.
- Home Renovation Savings Program — heat pumps — Save on Energy (IESO) and Enbridge Gas, supported by the Government of Ontario. Read 2026-09-11. Programme launched 2025-01-28.OPEN. Cold-climate air source heat pump up to C$7,500 (C$1,250/ton) where primary heating is electricity, oil, propane or wood; up to C$2,000 (C$500/ton) where it is natural gas. Ground source up to C$12,000 / C$3,000 on the same split. Heat pump water heater C$500. AND THE THING A FURNACE CALCULATOR MUST SAY: there is NO high-efficiency natural gas furnace rebate in either stream. The C$250 Enbridge furnace rebate that circulates belonged to the earlier Home Efficiency Rebate, not to this programme. The heat-pump page also states that contractor registrations are currently paused.
- Residential Equipment Replacement Rebate — SaskEnergy. Read 2026-09-11.OPEN, and the only confirmed Canadian FURNACE rebate with a body-published amount: C$325 for a high-efficiency natural gas furnace at 97% AFUE or better. Also C$750 for a 95%+ boiler and C$800 for a 95%+ combi boiler. Replacement of existing equipment only, installed by a SaskEnergy Network Member or TSASK-licensed contractor, applications within 120 days. The 97% threshold is what the live page states; a reported 2026-08-17 effective date for dropping 96–96.9% AFUE units could not be confirmed on the page and is therefore not asserted.
- Air source heat pump rebate — Efficiency Manitoba. Read 2026-09-11.OPEN. C$2,000 for a centrally-ducted cold-climate air source heat pump; C$1,500 ductless. Must supplement an electric-resistance or natural gas system (propane and oil conversions also qualify); primary residence; registered contractor; within 90 days of installation; cannot replace an existing heat pump. NO Efficiency Manitoba natural gas furnace rebate amount could be found. Homeowner.ca's Manitoba figures of C$1.65/sq ft and C$2.50/sq ft CONTRADICT the utility's own flat amounts and are not used.
- Rebates for renovating your heating system — BC Hydro. Read 2026-09-11.OPEN, with a narrow eligibility that matters: C$4,000 whole-home heating, C$1,500 partial, and the heat pump must replace a PRIMARY ALL-ELECTRIC system — electric baseboards or an electric forced-air furnace. Self-install is ineligible. A time-limited bonus of up to C$1,000 applies to installations completed, invoiced and paid 2026-08-01 to 2026-10-31, applied for by 2026-11-30.
- LogisVert financial assistance — residential — Hydro-Québec. Read 2026-09-11. Document version 2026-06-11.OPEN. Heat pump C$50 per 1,000 BTU/h at −8 °C, or C$120 if cold-climate classified, for ENERGY STAR units installed on or after 2025-11-26. A 5% bonus for combining measures. NO natural gas furnace measure. Its geothermal figures are contradicted between Hydro-Québec's own residential page (C$250 per 1,000 BTU/h, C$18,000 cap) and its installer guide (C$750 and C$54,000) — geothermal is therefore NOT modelled on this route at all rather than one of two conflicting figures being picked.
- Closed: Canada Greener Homes Grant — Natural Resources Canada. Read 2026-09-11. Date modified 2026-08-31.CLOSED to new applications since 2024-02-27; final documents were due 2025-12-31. Cited so the page can tell a reader who has heard of it that it is gone, rather than leaving it silently absent.
Every source above is Canadian. No US cost dataset, survey or price has been converted or used as a proxy anywhere on this route, and no exchange rate appears in its code. Two of the sources are federal government primary sources — Job Bank for wages and the building codes' own climatic design data for degree-days. The installed cost bands are not, and that is said rather than hidden: no Canadian government body and no Canadian industry association publishes furnace installed cost. All figures are before GST, HST and PST. Estimate only — get written quotes from licensed Canadian HVAC contractors, and have a CSA F280 heat-loss calculation done rather than sizing from floor area.
Next steps
The other appliance in the same mechanical room is usually on the same replacement clock, and in Canada it may not even be yours — the Canadian water heater rent-vs-buy calculator prices the rental buyout schedule that has no US equivalent. If the furnace is going in as part of a larger job, the Canadian home renovation cost calculator and the basement renovation cost calculator cover the rest in CAD — and a basement finish is where ductwork usually has to be rerouted anyway. If the roof is next on the list, the Canadian roof replacement cost calculator prices it by province with the eave-protection membrane the code requires. Before buying a bigger furnace, though, price the cheaper half of the same problem: the Canadian attic insulation cost calculator works from what Section 9.36 of the building code actually requires in your climate zone — and it carries the one column no American attic calculator has, because the code publishes a LOWER ceiling requirement for a house with a heat recovery ventilator. Insulate first and the furnace you need is smaller. And if the furnace failed in January and the money has to come from somewhere, the Canadian HELOC calculator shows what is actually borrowable against the house under Canadian lending limits.
This estimate does not include a humidifier. If one is going on the new furnace, the Canadian whole-house humidifier cost calculator prices bypass, fan-powered and steam units in C$ with your province's sales tax, and shows what a steam unit costs to run at your province's electricity price.
Frequently asked questions
How much does it cost to replace a furnace in Canada in 2026?
It depends on the province more than most people expect. FurnacePrices.com's regional table, updated 10 August 2026, publishes British Columbia highest at C$4,500–C$8,500 installed for a gas furnace and Manitoba and Saskatchewan lowest at C$3,200–C$6,500. Ontario is C$4,200–C$7,500, Alberta C$3,800–C$7,000, Quebec C$3,500–C$6,800, and the four Atlantic provinces are published as one region at C$3,800–C$7,200. All figures are Canadian dollars and before GST, HST and PST. Two independent Canadian publishers bracket that level: Reno Quotes puts a natural gas furnace at C$4,000–C$8,000 installed as of 27 January 2026, and FurnacePrices.ca puts the Canadian average at C$4,000–C$7,000 with a budget tier at C$3,000–C$4,000 and premium at C$7,000–C$9,000 or more. One caveat said plainly: no Canadian government body and no Canadian industry association publishes furnace installed cost. HRAI publishes none at all, and the utilities — Enbridge, FortisBC, Hydro-Québec, BC Hydro, SaskEnergy, ATCO — publish rebates rather than costs. These bands therefore come from Canadian commercial publishers, each dated, and that is stated rather than dressed up as an authority.
Does the climate zone really change what a high-efficiency furnace is worth in Canada?
By roughly a factor of two across populated Canada, and it is the single biggest reason an American furnace calculator gives a Canadian the wrong answer. The building codes' own climatic design data puts Vancouver City Hall at 2,825 heating degree-days below 18 °C and Winnipeg at 5,670: Winnipeg needs 61% more heating than Toronto's 3,520 for the same house, so the same efficiency upgrade saves 61% more fuel there. Work it through. Enbridge publishes a typical residential customer at 2,400 cubic metres of gas a year, which is an Ontario figure — that is why Toronto's degree-day is the reference. Scale it to Winnipeg and the same household burns about 3,866 cubic metres. Replacing a 78% furnace with a 98% one removes 20/98 of that, about 789 cubic metres a year; in Toronto, replacing an 80% with a 96% removes about 400. And the zone is a separate question from the province on purpose: Thunder Bay is in Ontario and sits at 5,650 degree-days, Québec City at 5,080 is colder than both Halifax and Calgary, and British Columbia contains both the mildest populated climate in the country and interior valleys colder than southern Ontario. One honest limitation — these degree-days are a 1961–1990 historical normal computed station by station and interpolated from maps, not current climate, and the 2025 National Building Code's new forward-looking climate data does not cover degree-days.
Is there a rebate for a high-efficiency gas furnace in Canada?
In one province, and it is worth saying which so nobody counts on money that is not there. SaskEnergy's Residential Equipment Replacement Rebate pays C$325 for a high-efficiency natural gas furnace at 97% AFUE or better — replacement of existing equipment only, installed by a SaskEnergy Network Member or a TSASK-licensed contractor, applications within 120 days of installation. It also pays C$750 for a 95%+ boiler and C$800 for a 95%+ combi boiler. That is the only confirmed Canadian gas FURNACE rebate with a body-published amount found on 11 September 2026. Ontario in particular has none: the live Home Renovation Savings Program from Save on Energy and Enbridge Gas carries heat pumps, insulation, windows, air sealing and a heat-pump water heater, and no gas furnace measure in either of its streams. The C$250 Enbridge furnace rebate still circulating on comparison sites belonged to the earlier Home Efficiency Rebate. Heat pumps are a different story and are well funded: up to C$7,500 in Ontario where primary heating is electricity, oil, propane or wood but only up to C$2,000 where it is natural gas; C$4,000 from BC Hydro, though only where the heat pump replaces a primary all-electric system, so a gas-furnace household does not qualify; C$2,000 ducted or C$1,500 ductless from Efficiency Manitoba. Closed, and named so their absence is not a mystery: Enbridge's Home Efficiency Rebate Plus (intake closed 5 February 2024), the federal Canada Greener Homes Grant (27 February 2024), NRCan's Oil to Heat Pump Affordability (intake closed 31 July 2026) and SaskPower's Home Efficiency Retrofit Rebate (April 2026).
What size furnace do I need for my house in Canada?
This calculator will not tell you, and the refusal is deliberate. No Canadian source publishes a BTU-per-square-foot sizing rule, and the Canadian standard for residential heat loss is CSA F280, which a contractor has to actually run against your construction, insulation, windows, air tightness and orientation. A calculator that multiplied your floor area by a made-up factor and presented the output as a load calculation would be inventing the one number a homeowner is least able to check. What is published, and what this calculator uses, is FurnacePrices.ca's cost ladder BY SIZE in Canadian dollars: 40,000 BTU at C$3,500–C$4,500 mid-range, 60,000 at C$4,000–C$5,000, 80,000 at C$4,500–C$5,500 and 100,000 or more at C$5,000–C$6,500, with a premium column C$1,000–C$1,500 above each. So the size is an input here and the guidance attached to it is rough orientation only: 40,000–60,000 BTU suits a small or well-insulated house, 80,000 is the common Canadian replacement, and 100,000 or more suits a large or leaky one. Oversizing is the usual error and it costs comfort as well as money — an oversized furnace short-cycles, which wears the ignition and leaves the house unevenly heated.
How much does ductwork add to a furnace replacement in Canada?
It is the line that most often turns a C$6,000 job into a C$12,000 one. A like-for-like swap into sound existing ducts adds nothing — that is what the published installed bands already describe. Modification is priced per linear foot because that is the only unit a Canadian source published: flexible duct C$15–C$25 and galvanized steel C$30–C$45 per linear foot, from a Canadian duct contractor's figures published 6 April 2026, with labour at C$90–C$150 an hour. No Canadian source read publishes a per-register or per-run figure, so none is used. Full replacement is C$4,500–C$7,500 for a typical single-family home, rising to C$6,500–C$10,000 for 1,501–2,500 square feet and C$9,000–C$14,000 or more for 2,501–3,500. All Canadian dollars, before tax. One structural consequence worth naming: a ductless mini-split heat pump needs no ductwork at all, published at C$5,000–C$8,000 installed for a single zone, which is often why it wins outright in a house whose ducts would otherwise need replacing — at the cost of heating the rooms it has heads in and not the others.
Why does this calculator not show a dollar saving for a furnace outside Ontario?
Because only one Canadian residential gas rate schedule was read, and pretending otherwise would hand a reader an Ontario number wearing their own province's name. That schedule is Enbridge Gas's Rate 1 for its EGD zone, effective 1 July 2026: gas supply 9.0498¢ plus first-block delivery 14.3745¢, so 23.4243¢ a cubic metre, with a C$27.69 monthly customer charge payable whatever you burn. Enbridge's own Union South zone published a materially different gas supply charge on the very same date, which means Ontario is not even one rate — so one Ontario rate certainly cannot stand in for Alberta's or Manitoba's. Outside Ontario the saving is therefore reported as a volume in cubic metres and the dollar line is absent with the reason on screen. The result is that a Manitoba reader gets the largest saving volume this calculator produces — around 789 cubic metres a year going from 78% to 98% AFUE in the Prairie climate — with no dollar figure attached. That is an honest output rather than a broken one: multiply the volume by the rate on your own bill. The same refusal applies to heat pumps for a different reason: no Canadian source read publishes a seasonal coefficient of performance for a cold-climate heat pump at a named Canadian degree-day, so a heat pump returns a capital cost and a rebate with no fuel saving, and a US HSPF rating has not been converted to fill the gap.
Is a heat pump cheaper than a gas furnace in Canada?
Not to buy, and the gap is wide enough that the rebate is usually the whole argument. FurnacePrices.ca publishes a cold-climate ducted central heat pump at C$12,000–C$18,000 installed against C$4,000–C$7,000 for a high-efficiency gas furnace — and the cold-climate specification is the right one for most of Canada, so the lower C$7,000–C$12,000 standard ducted band is not the fair comparison. A single-zone ductless mini-split is C$5,000–C$8,000, and multi-zone C$8,000–C$16,000 or more. Against that, the rebates run the other way: up to C$7,500 in Ontario, C$4,000 from BC Hydro, C$2,000 ducted from Efficiency Manitoba, and Hydro-Québec's LogisVert at C$50 per 1,000 BTU/h or C$120 if the unit is cold-climate classified. But read the eligibility rather than the headline, because it is where the money usually disappears: Ontario's C$7,500 falls to C$2,000 where the home's primary heating is natural gas, BC Hydro's C$4,000 requires the heat pump to replace a primary all-electric system so a gas household does not qualify at all, and Efficiency Manitoba's requires it to supplement an existing electric-resistance or gas system. This calculator does not model a running-cost comparison between the two, because no Canadian source read publishes a seasonal coefficient of performance at a named Canadian degree-day — and without that, a fuel-cost comparison between gas and a heat pump in a Canadian winter would be a guess with a decimal point on it.
Do furnace prices vary within a province in Canada?
Substantially, and by distance from a city rather than by anything about the appliance. FurnacePrices.ca is the one Canadian publisher that stated a methodology for this rather than printing an unexplained range, which is why this calculator uses it: a premium over a major-metro baseline of +5% to +15% for a suburb or small city, +20% to +40% for rural 1 to 2 hours out, and +50% to +60% or more for genuinely remote. The drivers are travel time, parts stocking, and how many contractors will quote at all. City-level Canadian figures are much scarcer than the internet suggests — the only one read with a verifiable date is HVAC Trust's Toronto band of C$4,300–C$7,000 for a standard residential replacement plus C$500–C$2,500 for a complex installation, last updated 20 May 2026. One ten-province city table was declined outright because it carries no publication date and its own illustration is dated March 2020. Underneath the geography sits labour: Job Bank's HVAC mechanic wages under NOC 72402, updated 19 November 2025, run from a median of C$29.76 an hour in New Brunswick to C$40.00 in Alberta, Saskatchewan and British Columbia — a federal wage report, not a contractor's billing rate, which carries overhead, vehicle, insurance and margin on top.
