For the past few years, most advice about energy upgrades in Canada started with the Canada Greener Homes Grant, along with a Canada Greener Homes Loan that offered up to $40,000 in interest-free financing. Both programs are now closed. The loan is no longer approving new applications, and December 31, 2025, was the last day for grant applicants to submit their documents.
In Toronto, that doesn't leave you entirely on your own. Ontario still offers rebates, the City still offers financing, and in October the federal government announced a new heat pump rebate for 2027. I'll come back to all three.
Without a grant tipping the scales, though, the real question gets clearer. Does the project pay you back? On your utility bills, in how comfortable your home feels, or when it's time to sell. Those three paybacks don't always arrive together, or on the same schedule.
I look at a renovation the way I'd look at any investment: what it costs, what it returns, and over what time frame. Here's how I'd sort out which upgrades are worth it for your house and your plans.
Start With What You Want the Upgrade to Do
A home office that's cold every afternoon is a different problem from a furnace nearing the end of its life. Either can justify spending money. The math changes with the reason.
If your furnace is on its last legs anyway, the number that matters is the difference in price between an efficient model and a standard replacement. That premium is what your savings need to cover. If you're replacing a system that still works well, the savings have to cover the full cost of the project.
Say, hypothetically, the more efficient model costs $2,000 extra and is expected to save $250 a year. Those savings would cover the difference in eight years, assuming they hold steady and leaving aside financing and maintenance.
Put another way, $250 a year on $2,000 is a 12.5% simple annual return. It's also after-tax money. A dollar you don't spend on heating is a dollar you never had to earn, and pay tax on, in the first place.
Then think about your timeline. If you plan to stay another decade, you have more years to collect on lower bills than someone getting ready to list next spring. When a contractor gives you a savings estimate, ask what it's based on for your particular home, and whether financing or maintenance would change the picture.
Comfort counts, too. You might be happy to pay for a bedroom that finally stays warm, even if the savings take longer to cover the cost. That's a perfectly good reason to do the work, as long as you know it's the reason.
Find the Real Problem Before You Pick the Fix
A bedroom that's always cold might come down to the ducts, the heating system, or the insulation. Each has a different fix, so it pays to know which one you have before you collect quotes.
That's what an EnerGuide home evaluation, sometimes called an energy audit, is for. An energy advisor registered with Natural Resources Canada (NRCan) looks at how your home uses and loses energy, including a blower-door test that measures how much air your house leaks. Afterward, you get an EnerGuide rating, which estimates how much energy your house uses in a year, plus a label and a report of recommended upgrades.
With that report in hand, you can hold every proposal up against the actual problem. If your concern is a cold bedroom, ask each contractor how their project fixes the cause the evaluation found.
The order of the work matters too. Better insulation and less air leakage reduce how much heating and cooling your home needs. As NRCan puts it, a newly retrofitted house "will need a smaller heating and cooling system than before the retrofit." Seal and insulate first, and the furnace or heat pump you buy later may not need to be as big.
Don't Skip the Smaller Fixes
Not every worthwhile project involves new equipment. Worn weatherstripping, gaps around windows, dirty furnace filters, and thin insulation are all worth a look. NRCan suggests changing or cleaning filters every three months, or sooner if they're clogged.
If your evaluation turns up air leaks and thin insulation, that's the natural place to start. NRCan calls air leakage control "the single most important retrofit activity" and says it "should be considered first in any retrofit strategy."
This is especially relevant in midtown, where many homes in neighbourhoods like Lawrence Park and Bedford Park are close to a century old. Character homes were built long before today's insulation standards, and some of the most useful work is the least visible.
Windows call for the same careful look. Some need only minor air sealing, while others need major upgrading or replacement. If yours are otherwise in good shape, weatherstripping or a storm window may be worth pricing alongside a new unit. In a character home, the original windows can be part of what buyers love, so it's worth asking whether they can be restored and sealed before you replace them. If the glass, sash, or frame has serious problems, replacing all or part of the window is the better option.
Ask three questions of every proposal, big or small. What will it fix? What's included? What should change afterward?
When a Bigger Upgrade Makes Sense
The strongest case for a high-efficiency furnace, boiler, or heat pump usually comes when the old system is due for replacement anyway. If yours still runs reliably, the savings from replacing it early have to cover the whole project. That makes it something to plan for over the next few years, not something to rush.
Frequent repairs and rising energy bills are good reasons to have your system evaluated. Doing that while it still runs gives you time to compare repair, replacement, and different system types before a breakdown in January makes the decision for you. If you might sell in the next few years, an aging system is also something a buyer's home inspector is likely to note.
Take a heat pump. It moves heat into your home in winter and out of it in summer, so one system handles both heating and cooling. Cold-climate models can keep working at outdoor temperatures as low as −30°C, though colder than that, you may need a backup heat source. Getting the size right matters as well. NRCan notes that undersizing or oversizing "can result in more costly and less efficient systems."
What a heat pump costs to run, compared with what you have now, depends on how much you use it and on local electricity and gas prices.
When you compare quotes, check that they cover the same work: equipment, installation, any electrical or duct changes, permits, and warranties. If a quote includes a savings estimate, ask what it assumes about your current system and the energy prices behind the math.
What's Still Available in Toronto
The federal grant is gone, but Toronto homeowners still have options. Program details change often, so check each one's current terms before you build it into your budget.
Ontario's Home Renovation Savings program. Run by Enbridge Gas and Save on Energy, it offers rebates on insulation, air sealing, windows and doors, heat pumps, and smart thermostats, among other upgrades. Insulation rebates go up to $7,700. Rebates are available whether you heat with electricity, natural gas, oil, propane, or wood.
The City of Toronto's Home Energy Loan Program (HELP). You can borrow up to $125,000, or 10% of your home's current assessed value if that's less, at fixed rates that currently run from 3.83% for a five-year term to 5.12% for twenty years, plus a 2% administrative charge. You repay it through your property tax bill, you can pay it off at any time, and it can be combined with provincial, federal, and utility rebates.
The new National Heat Pump Rebate. In October, the federal government announced a $2 billion heat pump rebate, expected to launch in early 2027. Low- to median-income households could receive up to $10,000, and households above the median up to $2,000. Officials are still exploring whether heat pumps installed before launch could qualify, so if one is on your list, it may be worth getting quotes now and confirming the rules before you sign.
The Canada Greener Homes Affordability Program. For eligible low- to median-income homeowners and tenants, it covers the full cost of recommended retrofits. It's delivered through the provinces and territories, so what's available depends on where you live.
If a quote counts on a rebate or program, check it against that program's actual requirements before you rely on it.
What Energy Upgrades Mean When You Buy or Sell
If you're selling in the next year or two, sort projects into two piles. One is fixing something a buyer's home inspector would flag. The other is adding an upgrade you hope will raise the price. The first protects your sale. The second depends on how buyers in your neighbourhood respond, and in Toronto, that's micro, micro, micro specific.
There's also a standard way to show what's been done. Because EnerGuide ratings are calculated under standard operating conditions, such as thermostat settings, hot water use, and the number of occupants, homes in a region can be compared on the building itself. New windows show up in listing photos. Better insulation and a high-efficiency furnace don't, and a rating done after the work can capture them.
Keep the paperwork: your EnerGuide label and upgrade report, equipment models, installation dates, and warranties. It shows a buyer what's been done, and it gives us something concrete to work with when we decide how to present your home.
If you're buying, ask for the home's utility history and whether it has an EnerGuide rating. A rating describes the house under standard conditions, while the bills reflect the people who lived there, which is why NRCan says not to expect a home's actual energy use to match its rating. Ask about the age and condition of the heating system, and any past evaluations, too. A furnace near the end of its life is a cost you'd be taking on, and it belongs in the conversation about price.
How to Weigh Your Next Project
For any upgrade you're weighing, line up five things side by side: the problem it fixes, the full installed cost, the expected savings, the comfort it adds, and how long you plan to stay. If a move is on the horizon, add what the work would mean to buyers in your area.
Laid out that way, the choice between a modest repair, a bigger replacement, or waiting for better timing usually gets much clearer. Fix the cause. Spend where it pays you back. Plan for the rest.
Whether you're settling in for the long haul or starting to think about a move, I'm happy to talk through what buyers in your neighbourhood notice and how that might shape the projects you take on. No pressure. Just good information before you spend.
