Ontario homeowners have access to one of the most generous rebate programs in Canada right now. The Home Renovation Savings Program offers up to $7,500 for a cold-climate air-source heat pump, up to $12,000 for ground-source, and up to $5,000 for rooftop solar. This guide explains Ontario home energy rebates and which upgrades actually pay off at Ontario prices.
Electricity and gas prices sit near the middle of the Canadian range, so results depend on how you heat today. Try the heat pump calculator or the solar calculator, then see full details on the Ontario rebates page.
Ontario homes buy electricity through local distribution companies such as Hydro One, Toronto Hydro and Alectra, and most natural gas comes from Enbridge Gas. The grid runs mainly on nuclear and hydro, with natural gas plants covering peaks. An all-in rate of roughly $0.17 per kWh is close to the Canadian average, and you can choose Time-of-Use, Tiered or Ultra-Low Overnight pricing.
Most Ontario homes heat with natural gas, with electric baseboards, oil and propane common in rural areas. With gas at roughly $0.48 per m³ and power at roughly $0.17 per kWh, a cold-climate heat pump at a typical seasonal COP of 2.2 to 3.0 costs about the same as a high-efficiency gas furnace to run, sometimes a little more or less. Homes on oil, propane or baseboards usually save a lot.
The Ontario rebate of up to $7,500 shortens payback considerably, especially if your furnace or air conditioner is due for replacement anyway. A dual-fuel system is another option for gas homes. Compare options in the heat pump vs gas furnace guide.
Solar in Ontario is a moderate investment. Yields are roughly in the middle of the Canadian range, and at typical costs of $2.40 to $3.30 per watt, payback often runs well over a decade without rebates. The Home Renovation Savings Program's rooftop solar rebate of up to $5,000, plus up to $5,000 for a battery ($10,000 combined), improves the picture.
Ontario offers net metering through your local distribution company, so you earn credits for power you send to the grid. Check current rules with your utility and see solar payback in Canada and net metering in Canada.
The Home Renovation Savings Program offers up to $7,500 for a cold-climate air-source heat pump and up to $12,000 for a ground-source system. Check eligibility rules before you buy.
They can be, especially with the up to $5,000 rooftop solar rebate. Payback depends on your roof, system cost and price plan, so run the numbers with your own bill.
It depends on when you use power. Homes that shift heavy use to overnight often do well on Ultra-Low Overnight, while others save on Tiered or Time-of-Use.
