Basement Renovation Rebates and Tax Credits in Ontario: What Still Exists in 2026

Most of the government money people expect for a basement renovation in Ontario does not exist in 2026. The $80,000 federal secondary suite loan was cancelled before a single application opened, the Greener Homes grant and loan are closed, and there is no rebate for finishing a basement for your own family. What does exist is narrower: a federal tax credit worth up to $7,000 if the basement becomes a suite for a parent or a relative with a disability, insulation rebates of up to $2,300 through Ontario's Home Renovation Savings Program, flood-protection subsidies from your city, and an insured refinance for homes adding a suite.

We have finished more than 400 basements across the GTA since 2017, and the honest answer on rebates is shorter than most homeowners expect. Here it is, program by program.

The $80,000 suite loan is gone

In 2024 Ottawa announced the Canada Secondary Suite Loan Program: up to $80,000 at 2 percent over 15 years for a basement or laneway suite. It never launched. CMHC never published eligibility criteria or opened an application, and the November 2025 federal budget confirmed the government would not proceed with it. If a contractor or a mortgage ad still promises you that loan, they are working from a 2024 press release.

The Multigenerational Home Renovation Tax Credit: up to $7,000

This is the biggest real number, and it is for one situation: you build a self-contained secondary unit so that a senior or an adult eligible for the disability tax credit can live with family. The qualifying individual must be 65 or older by the end of the year the renovation finishes, or 18 or older and eligible for the disability tax credit. The relative they move in with must be 18 or older and a parent, grandparent, child, grandchild, sibling, aunt, uncle, niece or nephew of that person or of their spouse or common-law partner.

The credit is refundable and covers up to $50,000 of qualifying expenses at the lowest federal tax rate. For a renovation completed in 2025 that rate is 14.5 percent, so the maximum is $7,250. For one completed in 2026 the rate drops to 14 percent, which makes the ceiling $7,000. You claim it in the tax year the work is completed, not the year it started.

The unit needs a private entrance, kitchen, bathroom and sleeping area, and it has to meet your municipality's requirements for a secondary dwelling unit. That last clause matters. A basement with a kitchenette and no legal entrance will not pass, so the project has to be designed as a legal suite from the first drawing. Our 2026 legal basement checklist covers the rules, and our legal basement apartment service handles the permit side.

Materials, permits, drawings and the work of licensed trades count. Your own labour, financing costs, appliances and home entertainment equipment do not. Each qualifying individual gets one claim in their lifetime.

Home Accessibility Tax Credit: smaller, more flexible

If the basement is adapted for a senior or a person eligible for the disability tax credit but is not a self-contained unit, the Home Accessibility Tax Credit may apply instead. It covers up to $20,000 of expenses a year for renovations that let the person get into the home or move around it safely: a wheel-in shower, grab bars, wider doorways, a stair lift. At the 2026 federal rate of 14 percent that is worth up to $2,800. The same dollar cannot be claimed under two credits.

Insulation rebates: up to $2,300, but only if you plan ahead

Ontario's Home Renovation Savings Program, delivered by Enbridge Gas and Save on Energy, pays for work almost every basement finish includes. Insulating 100 percent of the basement walls to more than R-22 earns $1,500; R-10 to R-22 earns $900. Insulating at least half the slab pays $500 and the foundation header pays $300, so a full basement can collect $2,300 on insulation alone, plus up to $250 for air sealing and a $600 rebate toward the two energy assessments.

Here is the catch that eliminates most people. A registered energy advisor has to assess the house before any work begins, you need at least two qualifying upgrades, and a follow-up assessment happens when the work is done. If the first time you hear about this is after the framing is up, the rebate is gone. Book the assessment before demolition is scheduled. The program is for owners of detached, semi-detached and row homes on Enbridge natural gas or the Ontario electricity grid, and as of November 2026 it lists no end date.

What those R-values look like on the wall is covered in our basement insulation guide.

Flood protection: your city, not the province

Backwater valves and sump pumps are subsidized by municipalities, and the amounts differ between Toronto, Mississauga, Vaughan and Markham. We keep those current in our GTA basement flooding rebates guide. Apply before the work, not after.

Financing that exists: the insured suite refinance

Since January 15, 2025, homeowners adding a legal secondary suite can refinance with an insured mortgage for up to 90 percent of the home's value after the renovation, on homes worth up to $2 million, with amortization up to 30 years. The owner or a close relative has to live in one of the units, the suite has to be self-contained and legal, and it cannot be a short-term rental. This is financing, not a grant. You pay the mortgage insurance premium and your lender's rate, so it suits a project where the suite's rent carries the payment. Our financing page covers the options for a basement finished for your own family.

What is closed

The Canada Greener Homes Grant is closed; December 31, 2025 was the last day to submit documents. The Greener Homes Loan is closed to new applicants. Ontario's Seniors' Home Safety Tax Credit covered the 2021 and 2022 tax years only. And there is no HST rebate on a basement finish: the federal new housing rebate requires a substantial renovation of the whole home, which a basement project on its own does not meet. Budget the full 13 percent.

What this means for your budget

For most of our clients, government money changes a basement budget by two or three thousand dollars, not twenty. The exception is a family building a suite for a parent, where the tax credit, the insulation rebate and the insured refinance can stack. Our Toronto basement finishing cost guide shows what real projects cost per square foot, and the cost calculator gives you a number for your own square footage before anyone comes to the house.

FAQ

Is there a government grant for finishing a basement in Ontario in 2026?

Not for a basement finished for your own use. What exists is a federal tax credit for a secondary unit housing a senior or a person with a disability, insulation rebates through the Home Renovation Savings Program, and municipal flood-protection subsidies.

How much is the Multigenerational Home Renovation Tax Credit worth?

Up to $50,000 in qualifying expenses at the lowest federal tax rate: $7,250 for renovations completed in 2025 and $7,000 for those completed in 2026. It is refundable and can be claimed once per qualifying individual.

Does the $80,000 secondary suite loan still exist?

No. It was announced in 2024, never opened for applications, and the November 2025 federal budget confirmed it will not proceed. The insured refinance for secondary suites, up to 90 percent of post-renovation value, is the federal measure that did take effect.

Can I get a rebate for insulating my basement walls?

Yes, through the Home Renovation Savings Program: $1,500 for insulating all basement walls above R-22, $900 for R-10 to R-22, plus slab and header amounts. A home energy assessment must happen before work starts, and you need at least two qualifying upgrades.
