Short answer
For most Canadian homes heated with oil, propane or electric baseboards, a cold-climate heat pump is worth it in winter and cuts heating costs a lot. If you heat with natural gas, the answer depends on your province's gas and electricity prices, and in some provinces gas stays cheaper to run.
Key takeaways
- Modern cold-climate heat pumps typically keep producing heat down to about -25 to -30 °C.
- Over a full Canadian heating season they typically deliver 2.2 to 3.0 units of heat for every unit of electricity.
- Homes on oil, propane or electric baseboards usually see the biggest savings.
- Homes on natural gas save in some provinces and pay more in others, so run the numbers first.
- Most installs keep a backup heat source for the coldest nights.
Is a heat pump worth it in a Canadian winter? For many homes, yes. A cold-climate air-source heat pump keeps heating your home well below freezing, and many models still produce heat at -25 to -30 °C. Whether it saves you money depends mostly on what you heat with today and what you pay for electricity.
If your home uses oil, propane or electric baseboards, a heat pump usually cuts your heating bill by a large margin. If you heat with natural gas, savings depend on your province. In Quebec, BC and New Brunswick a heat pump is often cheaper to run than gas. In Alberta and Saskatchewan, cheap gas and pricier electricity usually keep the furnace ahead on running cost alone.
How heat pumps perform in Canadian cold
A heat pump moves heat from outdoor air into your home. Even at -20 °C, outdoor air still holds heat the system can capture. As the temperature drops, the unit works harder and its efficiency falls. Efficiency is measured as COP, the units of heat delivered per unit of electricity used.
- Mild days (around 5 °C): COP is typically 3 to 4.
- Around -15 °C: COP typically falls to about 2.
- Near the unit's limit (-25 °C or below): COP drops toward 1.5 or lower, and heat output shrinks.
Averaged over a whole Canadian heating season, cold-climate models typically land between 2.2 and 3.0. Milder coastal areas like the Lower Mainland sit at the top of that range. The Prairies sit at the bottom. Ground-source systems do better, around 3.5 or more, because the ground stays at a steady temperature. See our guide to geothermal heat pumps for that option.
Cold-climate models matter
Older and standard heat pumps lose capacity quickly below about -10 °C. If you live anywhere with real winters, ask for a model rated for cold climates and check its heating capacity at -15 °C and -25 °C on the spec sheet. Rebate programs often require a cold-climate model anyway.
Backup heat for the coldest nights
Most Canadian installs include a backup. That backup can be:
- Electric resistance strips inside the air handler. Simple and cheap to install, but they run at a COP of 1, so heavy use raises your bill.
- Your existing furnace, in a hybrid or dual-fuel setup. The heat pump handles most of the season and the furnace takes over in deep cold. Our hybrid heating guide explains how the switchover works.
- Existing baseboards or a wood stove, common with ductless systems.
In much of southern Canada, temperatures below -25 °C happen only a handful of nights a year. A well-sized heat pump can carry most of the load, and the backup covers the rest.
Is a heat pump worth it? The verdict by fuel
The table compares typical cost per 1,000 kWh of heat delivered to your rooms, using approximate November 2026 prices. Your exact numbers will differ.
| Current heating | Typical cost per 1,000 kWh of heat | Heat pump instead (typical) | Verdict |
|---|---|---|---|
| Heating oil (80-85% efficient) | About $180-$195 | About $35-$110 | Usually strong savings |
| Electric baseboard | About $85-$240 (your electricity rate) | Roughly 55-70% less | Usually strong savings |
| Propane (95% furnace) | About $135 | About $35-$110 | Usually worth it |
| Natural gas (95% furnace) | About $39-$127, by province | About $35-$110 | Depends on your province |
Heat pump costs here assume a seasonal COP of 2.2 to 3.0. For a province-by-province breakdown for gas homes, read heat pump vs gas furnace running costs.
When a heat pump is not worth it
- You have cheap natural gas, a newer furnace, no central AC need and high electricity rates, as is typical in Alberta and Saskatchewan.
- Your home is very leaky and poorly insulated. Fix air leaks first. A smaller heat pump in a tighter home often costs less overall. Start with air sealing.
- Your electrical panel needs a costly upgrade and your savings are small.
Other reasons people choose one
A heat pump also cools your home in summer. If your air conditioner is near the end of its life, a heat pump costs only a little more and replaces it. It also lowers your home's emissions, especially in provinces with clean grids like Quebec, BC, Manitoba and Ontario.
How to decide for your home
- Find your annual heating fuel use on last year's bills.
- Enter it in our heat pump calculator to compare running costs.
- Check your province's current programs on our rebates page. Ontario's Home Renovation Savings Program offers up to $7,500 for a cold-climate air-source heat pump. Oil-heated homes may qualify for the federal Oil to Heat Pump Affordability program.
- Get two or three quotes, and ask each installer to show sizing based on a heat loss calculation.
Frequently asked questions
Do heat pumps work at -30 °C in Canada?
Many cold-climate models keep producing some heat to about -25 to -30 °C, but output and efficiency drop sharply near that limit. Most Canadian homes keep a backup heat source for the coldest nights.
Is a heat pump cheaper than gas in Canada?
It depends on your province. Heat pumps are often cheaper to run than gas in Quebec, BC, New Brunswick and Nova Scotia, while cheap gas usually wins on running cost in Alberta and Saskatchewan.
Do I still need a furnace with a heat pump?
Not always. Many homes use electric backup strips instead, while others keep the furnace as backup in a dual-fuel setup. The right choice depends on your climate, fuel prices and the age of your furnace.
How much can a heat pump save on oil heating?
Oil heat typically costs about $180 to $195 per 1,000 kWh of heat at current prices, while a cold-climate heat pump typically costs about $35 to $110 for the same heat. Most oil-heated homes see large savings.
