Cold-climate heat pumps sized for a Toronto winter

Typical cost in Toronto and the GTA: $9,000 to $18,000 (Cold-climate ducted air-source heat pump installed on existing ducts, before rebates). By level of work: Ductless mini-split, one zone: $3,500 to $8,000; Ductless multi-zone, 2–4 heads: $8,000 to $17,000; Cold-climate ducted system: $9,000 to $18,000; Hybrid with a gas furnace: $9,000 to $19,500. The type of system moves the price most: one ductless head costs far less than a cold-climate ducted system, and a hybrid that also replaces the furnace costs more again. Size, the state of the ducts and electrical capacity decide where a quote lands. These are typical ranges, before HST, with prices checked in 2026; your estimate is built from your own measurements and choices.

Home Renovation Savings, run by Enbridge Gas and Save on Energy, is open. For a cold-climate air-source heat pump it lists $500 per ton, up to $2,000, in a home heated with Enbridge gas, and $1,250 per ton, up to $7,500, in a home heated with electricity, oil, propane or wood. The model must be on the NRCan cold-climate list, a participating contractor must apply, and pre-approval is mandatory before installation. The Canada Greener Homes Grant and Loan are closed. The federal government has announced a National Heat Pump Rebate, launching in early 2027: $2,000 for eligible households, or up to $10,000 for eligible households below the median income, with no energy audits. Toronto says eligible whole-house heat pumps installed on or after November 1, 2026 may qualify.

Cold-climate models are built for low outdoor temperatures, which is why the rebate program only accepts them. Capacity still drops as it gets colder, so ask for the model number and its heating capacity at −15°C in writing and compare that with your heat loss calculation. A hybrid system keeps a gas furnace as backup for the coldest days.

You can. In a hybrid, or dual-fuel, system the heat pump does most of the heating and the furnace takes over through switchover controls. Published prices for packaged dual-fuel systems run $9,000 to $19,500. Gas work is done by a TSSA-registered contractor with certified gas technicians.

Usually, yes. Toronto lists installing or modifying a heating system among the work that needs a building permit, and a heat pump heats the house. The 2026 fee schedule does not name heat pumps; for a house it lists flat fees of $214.79 for heating and ventilating only, with no ductwork, and $270.64 for heating, ventilating and air conditioning, and we confirm with Toronto Building which applies before the install date. The electrical connection is also reported to the Electrical Safety Authority by the licensed electrical contractor.

If the house has ducts in good shape, a ducted heat pump uses them and one system serves every room. Ductless mini-splits suit houses with boilers or baseboards, additions and rooms the ducts never served. A single-zone ductless system runs $3,500 to $8,000, and a multi-zone system with two to four heads $8,000 to $17,000.

A heat pump needs its own 240 V circuit and a disconnect at the outdoor unit. Many 200 A panels have room for it. A 100 A service may not, and a 100 A to 200 A upgrade on an overhead service typically costs $2,500 to $5,000. The electrical contractor checks the panel at the estimate so that cost is known before you sign.
