In short
Installers size a Grimsby heat pump to a January design temperature of −16°C, a degree milder than Hamilton’s, and cold-climate models keep heating below that. We found no Town heat pump loan or rebate, so the money comes from Home Renovation Savings: up to $7,500 in a home heated by electricity, oil, propane or wood, or up to $2,000 in an Enbridge gas home. Zoning lets an air conditioning unit sit in a rear or interior side yard, 0.6 m from the lot line. It doesn’t name heat pumps, so confirm yours with the Town.

What does a heat pump cost in Grimsby after rebates?
In Grimsby, as across Ontario, a ducted cold-climate heat pump costs $12,000–$19,000 installed in a typical 2,000 to 2,500 sq ft home. In a home heated by electricity, oil, propane or wood, Home Renovation Savings pays $1,250 per ton, up to $7,500, which leaves $8,250–$15,250 for a ducted system. In an Enbridge gas home it pays $500 per ton, up to $2,000, and a heat pump that keeps the furnace as backup comes to $4,500–$8,500 after the rebate.
The federal National Heat Pump Rebate adds $2,000, or up to $10,000 at or below an income limit that is $146,217 after tax for a household of four in Ontario. It covers installs from November 1, 2026 and opens in early 2027. Income-eligible homes heated by electricity or oil can get a heat pump free through the Energy Affordability Program.

Who supplies electricity and gas in Grimsby?
Grimsby Power supplies electricity across the town. Its licence also takes in a few Beamsville addresses and one in Grassie, and leaves nine Mud Street East addresses in Grimsby to Niagara Peninsula Energy. Enbridge Gas holds the natural gas franchise.
Your heating fuel decides your Home Renovation Savings rate: a home heated by electricity, oil, propane or wood gets $1,250 per ton, 2.5 times the $500 per ton a gas-heated home gets. A gas-heated home must be an active Enbridge Gas residential customer to get the gas rate.
Grimsby Power’s programs page lists no heat pump rebate of its own and points to Save on Energy. Home Renovation Savings is the provincial program, and income-eligible households can get upgrades free through Save on Energy’s Energy Affordability Program.

How cold does Grimsby get, for sizing a heat pump?
The National Building Code of Canada 2020 gives Grimsby a January design temperature of −16°C. That is the 2.5% value: the temperature falls below it for no more than about 18 hours in a typical January. The 1% value is −18°C, and the area has 3,520 heating degree-days a year. A load calculation uses the design temperature to size the heat pump and decide how much backup heat to keep.
What Grimsby’s homes are like
At the 2021 census, Grimsby had 11,395 occupied homes. 83% were owner-occupied and 64% were single-detached houses.
| Built | Share of homes |
|---|---|
| 1960 or earlier | 20% |
| 1961 to 1980 | 22% |
| 1981 to 2000 | 23% |
| 2001 to 2021 | 35% |
Grimsby’s housing is newer than Hamilton’s: 20% of homes were built in 1960 or earlier, against 33% in Hamilton, and 35% in 2001 or later. 25% are semis or row houses, where a narrow side yard may not leave 0.6 m, so measure before you settle on a spot. A newer house with forced air usually suits a ducted heat pump.

Do you need a permit for a heat pump in Grimsby?
The Town’s pages don’t say. Its renovation permit page asks for mechanical plans “for major HVAC alterations”, but that is a drawing requirement for a job already getting a permit. We found no page on replacing a furnace, air conditioner or heat pump. Ask the Building Division before work starts, at 905-309-2022 or building@grimsby.ca.
The Town says work must meet zoning even when no permit is needed, and that it doesn’t issue permits for electrical work.
The electrical side is provincial. The Electrical Safety Authority requires a notification of work before any electrical job starts, and its fee guide has an "HVAC small job" category that names heat pumps. If a gas furnace stays in as backup, any work on it is for a TSSA-registered contractor.

Where can the outdoor unit go in Grimsby?
Section 4.9 f) of Zoning By-law 14-45 lets air conditioning units encroach into a required rear yard or interior side yard, no closer than 0.6 m to an interior or rear lot line. It doesn’t name heat pumps and doesn’t mention the front yard or an exterior side yard, so confirm your spot with Planning at 905-945-9634 ext. 2128 or planning@grimsby.ca.
The by-law doesn’t apply on land inside the Niagara Escarpment Development Control Area, which the Niagara Escarpment Commission controls. If your home is there, ask the Commission how it treats an outdoor unit.

Does Grimsby’s noise by-law cover heat pumps?
We found no item for air conditioners or heat pumps in By-law 11-22 and its amendments, and no decibel limit. Its general rule bars “unusual noise” and noises “likely to disturb the inhabitants”. It also bars noise that breaks an applicable Ontario noise publication, without saying which one fits a home unit, so compare sound ratings before you buy.

Does Grimsby have a heat pump loan or rebate?
We found none. The Town’s building FAQ says grants and rebates can help with upgrades such as heat pumps, and tells residents to check with Enbridge Gas. Its climate plan is about the Town’s own operations: it “does not address community-wide emissions from residents or businesses.” Today’s money is Home Renovation Savings and, once it opens, the federal rebate.

Common questions
Is there a heat pump rebate in Grimsby?
Yes, from the province: Home Renovation Savings pays $1,250 per ton of heat pump capacity, up to $7,500, in a home heated by electricity, oil, propane or wood, and $500 per ton, up to $2,000, in a home heated by Enbridge gas. The federal National Heat Pump Rebate adds $2,000, or up to $10,000 below an income limit, for installs from November 1, 2026; it opens in early 2027. We found no Town rebate. Every Ontario program.
Should I replace my furnace with a heat pump in Grimsby?
It depends on your fuel. A cold-climate heat pump sized to Grimsby’s −16°C design temperature can heat the house with electric backup, and many gas homes keep the furnace for the coldest days. Heat pump vs furnace compares the two.
Is a heat pump cheaper to run than gas in Grimsby?
Not compared with gas. At Ontario prices from November 1, 2026, 1,000 kWh of heat costs about $31 from an Enbridge gas furnace, $48–$66 from a cold-climate heat pump, $140–$159 from electric baseboards and $277–$288 from an oil furnace. The electricity prices are the Ontario Energy Board's province-wide rates, and only the delivery charges differ between distributors, so the figures are a close guide in Grimsby. A heat pump clearly lowers the bill in a home on baseboards, oil or propane. In a gas home, the case rests on replacing the air conditioner, the rebate and burning less gas, not on a smaller bill. Heat pump vs furnace works through a full year.
Does Grimsby Power have a heat pump rebate?
Grimsby Power’s programs page lists no heat pump rebate of its own and points to Save on Energy. Home Renovation Savings is the provincial program, and income-eligible households can get upgrades free through Save on Energy’s Energy Affordability Program.
How close to the property line can a heat pump be in Grimsby?
By-law 14-45 lets an air conditioning unit sit no closer than 0.6 m to an interior or rear lot line, in a required rear or interior side yard. It doesn’t name heat pumps, so confirm with the Town’s Planning staff.
How do I find a heat pump installer for the rebate in Grimsby?
Fill in the Home Renovation Savings heat pump form: the program emails a list of participating contractors. Hire from that list. The contractor files the application before any work starts, and an install done before approval gets no rebate. How Home Renovation Savings works.
How much does heat pump installation cost in Grimsby?
Grimsby pricing follows Ontario's provincial range: $12,000–$19,000 for a ducted air-source heat pump and $4,000–$8,500 for a single-zone ductless system. The Ontario row of the cost guide shows how those figures are built.
