Canadian heat pump vs gas furnace comparison calculator. Compares annual heating costs, 10-year total cost of ownership, and carbon emissions. Cold-climate heat pumps achieve COP of 2.5 to 3.5 at -15C and COP 4.0+ at 0C. Average natural gas price $1.30/m3 nationally, with regional variation. Includes federal carbon tax on gas ($80/tonne CO2e in 2024, rising annually). Canada Greener Homes Grant provides up to $5,000 for heat pump installation. Provincial rebates available in BC, Quebec, and Nova Scotia.

Formula
Converts your gas consumption to equivalent energy in kWh, then divides by the heat pump coefficient of performance (COP) to find actual electricity needed. A cold-climate heat pump with a COP of 3.0 uses one-third the energy of direct electric heating for the same heat output.
Canada FAQs
How much does a heat pump save vs a gas furnace in Ontario?
In Ontario, a cold-climate heat pump heating a 2,000 sq ft home costs approximately $1,100 to $1,400 per year in electricity, compared to $1,800 to $2,200 per year for natural gas (including the federal carbon tax). That is an annual savings of $500 to $800. Over 10 years, the heat pump saves $5,000 to $8,000 after accounting for the higher upfront installation cost.
Do heat pumps work in Canadian winters?
Yes. Modern cold-climate heat pumps (rated to -25C or lower) maintain a coefficient of performance (COP) of 2.0 to 2.5 even at -15C, meaning they produce 2 to 2.5 units of heat for every unit of electricity consumed. At -25C, some models switch to backup electric resistance heating. In most of southern Canada, a cold-climate heat pump handles 95% or more of winter hours without backup.
What rebates are available for heat pumps in Canada?
The Canada Greener Homes Grant offers up to $5,000 for installing a cold-climate heat pump. Some provinces add their own rebates: BC offers up to $6,000 through CleanBC, Quebec provides up to $5,000 through Chauffez vert, and Nova Scotia offers up to $3,000. Combined federal and provincial rebates can cover 30% to 50% of total installation costs.
How does the carbon tax affect gas furnace costs?
The federal carbon tax adds approximately 12 to 15 cents per cubic metre to natural gas. For a home using 2,500 m3 per year, that is $300 to $375 in carbon tax alone. The carbon price is scheduled to continue rising, making gas heating progressively more expensive compared to electric heat pumps powered by clean provincial grids.
What is the installation cost of a heat pump in Canada?
A cold-climate ducted heat pump typically costs $8,000 to $15,000 installed in Canada, depending on the system size and complexity. A ductless mini-split ranges from $4,000 to $8,000 per zone. After federal and provincial rebates, the net cost is often $5,000 to $10,000 for a whole-home ducted system.
Which provinces benefit most from switching to a heat pump?
Quebec and British Columbia benefit most because their electricity is cheap (7.5c and 12.5c per kWh respectively) and comes almost entirely from hydroelectric generation. In these provinces, a heat pump can cut heating costs by 40% to 60% compared to gas and reduce carbon emissions by over 90%. Alberta and Saskatchewan see smaller savings because electricity rates are higher and the grid is more carbon-intensive.
