Get Free QuotesPricing varies significantly across provinces due to climate demands, labour rates, local building codes, and market competition.
| Province / Region | Average Cost Range | Climate Factor | Market Notes |
|---|---|---|---|
| Ontario (Toronto, Ottawa, Hamilton) | $4,200–$7,500 | Moderate winters | Higher labour rates in the GTA |
| Alberta (Calgary, Edmonton) | $3,800–$7,000 | Harsh winters | Competitive market, high-capacity needs |
| British Columbia (Vancouver, Victoria) | $4,500–$8,500 | Mild coastal climate | Premium pricing, specialized installs |
| Quebec (Montreal, Quebec City) | $3,500–$6,800 | Cold winters | Variable contractor availability |
| Manitoba (Winnipeg) | $3,200–$6,500 | Extreme cold | Competitive pricing, efficiency critical |
| Saskatchewan (Regina, Saskatoon) | $3,200–$6,500 | Extreme cold | Furnace prices in Saskatoon and Regina track closely with Manitoba |
| Atlantic Provinces | $3,800–$7,200 | Moderate to cold | Island delivery premiums possible |
Rural homeowners typically face $200–$800 in additional travel fees, more limited contractor availability, and longer wait times during peak season. If you're in Ontario, we track live pricing for Hamilton, Kitchener, Cambridge, and Milton separately, since GTA-adjacent labour rates differ meaningfully from smaller markets.
Toronto and the GTA: the average furnace replacement cost in Toronto runs $5,200–$7,800 for mid-range systems. Downtown installs sometimes carry premium rates for parking/building access, condo board requirements, and higher urban-core labour costs. Popular brands here include Carrier, Lennox, and Goodman, and many contractors run seasonal promotions in spring and summer.
Calgary and Edmonton: $4,500–$6,800. Alberta's harsh winters (regularly below -30°C) push demand toward higher-efficiency models (95%+ AFUE), larger-capacity systems (100,000+ BTU), and two-stage or modulating furnaces built for extreme cold performance.
Vancouver: the furnace replacement cost in BC runs $4,800–$8,200 in the metro area. The mild coastal climate allows for slightly smaller-capacity systems, and many homeowners are pairing furnaces with heat recovery ventilators for better indoor air quality — or considering a heat pump alternative outright.

HVAC professionals lean on a simple industry benchmark: multiply the repair cost by the furnace's age in years. If the result exceeds $5,000, replacement typically represents the smarter long-term investment.
Example: a 15-year-old furnace needs a $400 heat exchanger repair. 15 × $400 = $6,000. Recommendation: replace, not repair.
Not sure which camp you're in? Our Repair or Replace Quiz walks through your furnace's age, symptoms, and repair history and gives you a straight answer in under a minute. If it's making unusual noises or short-cycling right now, the Furnace Troubleshooting Wizard can help you narrow down what's actually wrong before you call anyone. For a deeper dive into the warning signs, see our full guide on when to replace a furnace.
Want to see your own numbers instead of an average? Use the Furnace Savings Calculator to compare your current system against a high-efficiency replacement, or the Operating Cost Calculator to see what you're paying monthly right now.
Calculate the estimated monthly operating cost of your furnace with this quick quiz.
AFUE = Annual Fuel Utilization Efficiency. Standard furnaces are ~80–85%, high-efficiency models are 95–98%.
Better insulation = your furnace works less = lower monthly cost.
Colder climates mean your furnace runs far more hours per heating season.
Check your gas bill for the rate per cubic metre (m³). Average is around $1.20/m³.

GET FREE QUOTES| Option | Upfront Cost | Long-Term Impact | Best For |
|---|---|---|---|
| Replace Now | $3,000–$8,000 | Lower bills, better comfort, peace of mind | Furnaces 15+ years old, frequent repairs |
| Repair & Postpone | $300–$2,000/repair | Continued inefficiency, repeat-failure risk | Newer furnaces, single component failures |
| Do Nothing | $0 | Emergency replacement premium (15–30% more), safety risk | Almost never recommended in Canadian winters |
According to Natural Resources Canada's energy efficiency guidelines, upgrading from an 80% to 95% AFUE furnace typically delivers a 5–7 year payback period through energy savings alone.
| Scenario | Year 1 | Years 2–5 | 5-Year Total |
|---|---|---|---|
| New High-Efficiency Furnace | $6,500 replacement − $1,000 rebates − $500 energy savings | −$500/year energy savings + $150/year maintenance | $3,900 net cost |
| Continue with Old Furnace | +$500 higher energy + $800 repair | +$500/year energy + $600/year repairs | $4,900 net cost |
| Difference | $1,000 saved by replacing |
This simplified example assumes moderate repair frequency and typical energy savings. Your actual costs may vary.
| Removal Type | Cost Range | What's Included |
|---|---|---|
| Standard removal | $150–$350 | Basic disconnect and haul-away |
| Complex removal | $400–$700 | Difficult access, multiple components |
| Hazardous material disposal | +$200–$500 | Asbestos insulation present |
| Oil tank removal | +$500–$2,000 | Switching from oil to gas |
Before signing anything, confirm: is removal included in the quoted price? What happens if asbestos is discovered? Will the installation area be cleaned and prepped? Are disposal fees itemized separately? Some provinces also offer disposal rebates for retiring an old, inefficient furnace — check with your local utility provider.
Contractor financing (0% for 6–24 months on approved credit), HELOCs (typically 6–8% interest), and personal loans (6–12% APR) are now your most dependable savings levers for a standard furnace swap — rebates alone won't move the needle much unless you're pairing the furnace with a heat pump. For the full breakdown by lender type and current Ontario rebate programs, see our dedicated guide on furnace financing in Canada and Ontario furnace rebates.

| Hidden Cost | Typical Range |
|---|---|
| Electrical panel upgrade (older homes) | $1,200–$3,000 |
| Ductwork repair | $800–$3,500 |
| Ductwork replacement | $2,500–$6,000 |
| Permits & inspection | $50–$300 |
| Smart thermostat (installed) | $80–$350 |
| Gas line modification | $300–$2,500 |
| Emergency / after-hours premium | +15–30% |
Today's high-efficiency furnaces draw more consistent electrical loads than older pilot-light models, which is why 60–100 amp panels in older homes sometimes need upgrading. Ask your contractor to itemize every one of these before you sign — a "today only" quote that skips them is a red flag, not a deal.
Professional HVAC contractors build quotes from three components: equipment costs (40–50%) — the furnace, venting, and fittings; labour (30–40%) — removal, installation, testing, warranty registration; and overhead and margin (15–25%) — insurance, licensing, and profit.
Be cautious of any contractor who gives a verbal-only estimate, pressures "today only" pricing, quotes well below every competitor, skips permits or warranty registration, or can't produce proof of insurance and licensing. Premium-priced contractors, in exchange, typically offer 10+ year parts warranties, 24/7 emergency availability, and proper Manual J load calculations rather than eyeballed sizing.
Single-stage furnaces run at one speed — full blast — and are the most affordable but least consistent. Two-stage furnaces run at 60–70% capacity most of the time and ramp up only when needed, improving efficiency and comfort. Modulating furnaces adjust output in 1% increments from 40–100%, delivering the most consistent comfort at a premium price.
Increasingly, Canadian homeowners are also weighing a cold-climate heat pump as an alternative or hybrid partner to a traditional furnace — especially in regions where winters rarely dip below -15°C. We cover the full trade-offs in our furnace vs. heat pump comparison guide. If you're weighing that decision, the Is a Heat Pump Worth It? Quiz, Heat Pump Cost Calculator, and Heat Pump Recommendation Wizard can help you compare against the furnace numbers above. Already have a heat pump acting up? Try the Heat Pump Troubleshooting Wizard, and use the Heat Pump Size & BTU, Operating Cost, and Savings Calculator tools to model a hybrid system before you commit either way.
Warranty coverage matters just as much as the equipment itself: look for a 10–20 year heat exchanger warranty (the most expensive part to replace), a 5–10 year parts warranty, and confirm registration deadlines (often within 90 days) and whether coverage transfers if you sell the home.
Get at least three written, itemized quotes before deciding. Compare equipment specs, total warranty coverage, full installation scope and timeline, payment terms, and references — never decide on price alone. The cheapest bid frequently skips proper Manual J load calculations, which leads to an oversized or undersized system that short-cycles, wastes energy, and fails early.
The cheapest bid frequently comes from contractors cutting corners on proper Manual J load calculations, quality installation practices, adequate warranty support, and post-installation service. A furnace that's improperly sized or installed will cost you significantly more in energy bills, repairs, and premature replacement over its lifespan.
Bigger isn't better. An oversized system short-cycles, drastically reducing lifespan; operates inefficiently, wasting energy; creates uncomfortable temperature swings; never runs long enough to properly dehumidify; and costs more upfront without providing benefits. A proper Manual J calculation accounts for home size and layout, insulation levels, window quality and orientation, air leakage, and your local climate zone.
High-efficiency furnaces cost 20–30% more upfront, but the energy savings across Canada's extended heating season (October–April in most regions) make them worthwhile. Example: an extra $1,500 for 95% vs 80% AFUE, offset by $400/year in savings, pays back in 3.75 years — a $6,000 total saving over 15 years.
Hiring an unlicensed or underinsured contractor risks voided manufacturer warranties, failed inspections requiring costly rework, safety hazards (gas leaks, carbon monoxide), and no recourse if problems arise. Always verify credentials, check references, and confirm adequate insurance coverage.
Even the best furnace needs annual professional maintenance to keep the warranty valid, ensure safe operation, and maximize efficiency. Budget $120–$200/year — skipping it typically costs 15–20% in lost efficiency plus voided warranties and safety risk.
Most straightforward replacements take 6–10 hours. Complex jobs involving ductwork changes, panel upgrades, or difficult access can take 1–2 full days. Emergency same-day replacement is possible but usually carries a premium.
No — in most Canadian jurisdictions, gas furnace installation requires certified gas fitter licensing due to carbon monoxide, gas leak, and fire risks. DIY installation also voids manufacturer warranties and can violate your home insurance policy.
Late spring through early fall (May–September) offers the best pricing and contractor availability, with off-season discounts of 10–15% common. Don't delay a genuinely failing furnace during heating season for the sake of a discount, though — safety comes first.
As of August 2026, the federal Canada Greener Homes Grant is closed to new applicants, and most provincial programs have shifted toward heat pumps. Ontario's Enbridge program now offers just $250 for a furnace (only when bundled with two other upgrades), Alberta's old "Efficiency Alberta" program no longer exists, BC's CleanBC mainly rewards dual-fuel heat pump setups, and Quebec's Rénoclimat no longer covers heat pumps at all. Contractor 0% financing is now the more reliable savings option for a standalone furnace swap. Check your utility's site for current eligibility, since programs shift often.
If only your blower motor has failed, that's a repair, not a full replacement — furnace motor replacement cost in Canada typically runs $300–$900 including parts and labour, far below the $3,000–$8,000 range for a full system. Use the age × repair-cost rule above to confirm a motor swap is still the right call for your furnace.
Yes — "furnace renovation" is usually just another way homeowners describe a full furnace replacement, especially when it's bundled into a wider basement or HVAC renovation. The same $3,000–$8,000 furnace replacement cost range applies; if you're renovating ductwork, electrical, or venting at the same time, budget the additional line items from our hidden costs section above on top of the base furnace price.
A $3,000–$8,000+ investment feels substantial in the moment, but a properly sized, professionally installed high-efficiency furnace delivers reliable comfort and lower bills for 15–20 years. Once your furnace hits 15 years, or the repair-cost-times-age formula clears $5,000, the math almost always favours replacing rather than continuing to patch an aging system. Get multiple written quotes, confirm every line item — removal, permits, modifications — is included, check available rebates, and size the system properly with a Manual J calculation rather than a guess.
