Quick Answer
Most Ontario homeowners assume renovation tax credits are modest a few hundred dollars back on a permit, maybe a small rebate on insulation.
They’re right, if all they’re doing is a minor repair or a cosmetic refresh. But that assumption breaks down completely when the project in question is a full home renovation.
A complete home renovation whether that’s a full basement conversion, a whole-home gut renovation, a comprehensive kitchen and bathroom overhaul, or the creation of a legal secondary suite sits in an entirely different category when it comes to Canadian tax programs. The credits, rebates, and HST savings available to Ontario homeowners undertaking full-scope renovation projects can represent $15,000 to $40,000 or more in recovered costs on a typical Greater Toronto Area project. That number isn’t theoretical. It’s the result of stacking legitimate federal and provincial programs that are specifically designed to reward exactly this kind of investment.
This article is not for homeowners patching a crack, replacing a fixture, or repainting a room. Those projects don’t unlock what’s covered here. This article is for homeowners who are planning a serious, full-scope renovation and who want to understand every financial tool available to them before they start.
Here’s what we’ll cover:
What Is the Home Renovation Tax Credit in Ontario in 2026 and What Types of Projects Actually Qualify?
Key Takeaway: Ontario renovation tax credits, rebates, and HST savings available to homeowners undertaking full-scope renovation projects can represent $15,000 to $40,000 or more in recovered costs on a typical GTA project but only projects that meet CRA’s substantial renovation threshold unlock the most valuable programs.
Before diving into specific programs, it’s worth establishing a distinction that will determine whether any of this applies to your renovation: CRA does not treat all renovations equally, and neither do most rebate programs in Ontario. The type, scope, and intent of your renovation determines what you can access.
Tax credits versus tax deductions
These terms are often used interchangeably, but they work differently. A tax deduction reduces your taxable income, which indirectly lowers the tax you owe. A tax credit directly reduces your tax payable dollar for dollar. Some credits are non-refundable, meaning they can reduce your tax bill to zero but won’t result in a refund if the credit exceeds what you owe. Others are refundable, meaning you can receive the balance as a cash refund even if your tax liability is zero. As you’ll see, this distinction matters significantly when evaluating which programs to prioritise.
The concept of substantial renovation
The single most important concept for any Ontario homeowner planning a full renovation is “substantial renovation” as defined by the Canada Revenue Agency. This threshold is what separates projects that unlock the most valuable programs particularly the GST/HST New Housing Rebate from projects that don’t qualify at all.
Under CRA rules, a substantial renovation is – considered to have taken place where all or substantially all of the interior of a building, with the exception of certain structural components (the foundation, external walls, interior supporting walls, roof, floors and staircases), has been removed or replaced.
Meaning the interior of a home is essentially gutted, with 90% or more of the interior removed or replaced. The foundation, exterior walls, roof, floors, and staircases are excluded from this calculation; you don’t have to replace structural elements to meet the threshold, and if you do replace them, that work is still eligible for the rebate.
What the CRA is measuring is the livable interior:
Garages and crawl spaces don’t count.
What Does This Look Like in Practice?
Whether a renovation qualifies depends on how much of the livable interior is rebuilt as part of a larger project.
Typical Qualification Examples
| Renovation Type | Qualifies Toward “Substantial Renovation”? | Why |
| Full basement conversion | Yes | Creates new habitable living space with full systems upgrade |
| Whole-home gut renovation | Yes | Interior rebuilt to studs across living areas |
| Major kitchen rebuild (part of full-home reno) | Yes | Structural and system changes contribute to 90% threshold |
| Painting or cosmetic updates | No | Maintenance, not transformation |
| Single-room flooring replacement | No | Limited scope |
| Water heater or fixture replacement | No | Equipment upgrade only |
| General repairs | No | Restores rather than renovates |
Projects must significantly transform the interior, not simply update finishes.
Primary Residence Requirement
The federal GST/HST rebate applies only to your primary residence.
You may still qualify if:
Investment or rental properties you don’t occupy are generally not eligible.
Why 2026 matters
Program rules, income thresholds, and CRA interpretations are updated regularly. In 2026 specifically, the Multigenerational Home Renovation Tax Credit continues to be an active and underused program. The Canada Greener Homes Grant has officially closed to new applicants, but Ontario utility programs and interest-free loan options remain available for energy-related work within a full renovation. Staying current on what’s active versus expired matters and we’ll flag that clearly throughout.

How Does the HST Rebate Work on a Full Home Renovation in Ontario?
Key Takeaway: The Ontario provincial HST rebate allows homeowners who complete a qualifying substantial renovation to recover up to $24,000 and critically, the Ontario portion is available regardless of whether the federal rebate applies.
The GST/HST New Housing Rebate is the largest financial recovery program available to Ontario homeowners completing a full renovation, and it’s one of the most misunderstood. Most people associate it with purchasing a newly built home. What far fewer people realise is that it also applies to homeowners who substantially renovate an existing residence — and for a full gut renovation or complete basement conversion, the amounts involved are significant.
How the rebate works
Ontario’s HST rate is 13%, made up of a 5% federal component and an 8% provincial component. The GST/HST New Housing Rebate allows homeowners who have completed a qualifying substantial renovation to recover a portion of the HST paid on eligible renovation costs labour, materials, permits, and contractor fees.
The rebate operates in two parts:
For a full renovation project in the $100,000 – $200,000 range, the Ontario provincial rebate alone can represent a recovery of $10,000 – $24,000 depending on eligible costs and home fair market value. That is not a small number.
How this applies to RenoDuck’s project types
Important: a standalone basement renovation in a two-storey home, where the remaining floors are untouched, is unlikely to meet the 90% threshold on its own. The CRA measures the renovation against the total habitable square footage of the dwelling. This is a key reason why full-scope, coordinated renovation projects rather than isolated upgrades done room by room provide far greater financial return.
Primary residence requirement
The rebate applies to your primary place of residence. You must intend to live in the home as your principal residence following completion of the renovation. If the renovation is on a property you plan to sell immediately after completion, different rules apply and the rebate may not be available or may be treated differently for tax purposes.
Documentation CRA requires
To successfully claim the HST rebate on a substantial renovation, you will need:
Working with a licensed, registered contractor who issues proper invoices with their GST/HST registration number is not optional; it is a prerequisite for the rebate claim. This is one of the clearest reasons why full renovation projects handled by professional, permit-pulling contractors have a financial advantage that DIY or informal work simply cannot replicate.
RenoDuck handles permitting, provides properly itemised invoices with our GST/HST registration number, and manages the documentation your rebate claim depends on backed by a 15-year workmanship warranty.

What Is the Multigenerational Home Renovation Tax Credit and How Does a Full Renovation Qualify?
Key Takeaway: The Multigenerational Home Renovation Tax Credit (MHRTC) is a refundable federal tax credit of up to $7,250 for renovations that create a self-contained secondary unit for a qualifying senior or adult with a disability and because it is refundable, you receive it even if you owe no federal taxes.
The Multigenerational Home Renovation Tax Credit referred to as the MHRTC is one of the most valuable and underutilised federal tax credits currently available to Canadian homeowners. Introduced in 2023 and active in 2026, it is specifically designed for families investing in a renovation to create a self-contained living space for a qualifying family member. For RenoDuck clients creating legal basement suites, adding a self-contained unit within a whole-home renovation, or reconfiguring a main floor to accommodate a parent or adult family member, the MHRTC represents up to $7,250 in refundable cash back.
How the MHRTC works
The MHRTC is a refundable federal tax credit equal to 14.5% of eligible renovation expenses, on a maximum of $50,000 in qualifying costs meaning the maximum credit available is $7,250 per qualifying renovation.
Because it is refundable, you receive this amount even if you owe no federal taxes it comes back as a direct refund.
Note for 2026 filers: The CRA’s 2025 tax year page confirms the 14.5% $7,250 figures. Confirm the applicable rate with a tax professional or directly at canada.ca before filing.
To be eligible, the renovation must create a self-contained secondary unit within the eligible dwelling or on the same property.
The secondary unit must have its own:
Each of these is a firm CRA requirement. A bedroom addition off a shared hallway does not qualify. A sunroom converted to a bedroom for a parent, without a kitchen, does not qualify.
A fully finished basement suite with a private entrance, a complete kitchen, a bathroom, and a bedroom qualifies provided all other conditions are met.
Qualifying individuals and relations
The secondary unit must be created so that a qualifying individual can live with a qualifying relation.
In practical terms: if you’re renovating your home to create a basement apartment for your 67-year-old mother-in-law, you qualify. If you’re creating a self-contained unit for an adult sibling who is eligible for the DTC, you qualify. If you’re building a separate backyard laneway house for an aging parent on the same property provided local zoning permits it you also qualify.
How this applies across renovation types
One claim per qualifying individual, per lifetime
This is a critical limitation to understand. The MHRTC can only be claimed once per qualifying individual during their lifetime. If a credit has already been claimed for your mother in connection with a different property, you cannot claim it again for her at your home.
Planning and timing the renovation accordingly and confirming with a tax professional that no prior claim has been made is essential.
The renovation must be completed in the tax year you claim
Eligible expenses are those incurred during the renovation period from the first qualifying expenditure through to the final inspection or proof of completion. The claim is made in the tax year when the renovation period ends, regardless of when it started. If your renovation begins in late 2025 and the final inspection occurs in 2026, you claim it on your 2026 return.
Can I stack the MHRTC with the HST rebate?
Yes, with important nuance. You can benefit from both programs on the same renovation project, but the same expenses cannot be counted toward both claims. Expenses used to calculate the MHRTC cannot also be submitted for the HST rebate. In practice, this means splitting your renovation invoices strategically across both programs, a task that benefits significantly from professional tax advice. A well-planned $120,000 full basement renovation creating a legal secondary suite could potentially generate both an Ontario HST rebate and an MHRTC credit, collectively recovering $15,000 – $30,000+ depending on the project specifics and home value.

Are There Ontario Programs and Rebates That Apply to Full Home Renovations in 2026?
Key Takeaway: Both the Canada Greener Homes Grant and Loan are closed to new applicants as of 2026; active programs include the Canada Greener Homes Affordability Program, the Oil to Heat Pump Affordability Program (up to $10,000 federally), the City of Toronto HELP financing program, and municipal secondary suite incentive programs across the GTA.
Beyond the HST rebate and MHRTC, Ontario homeowners undertaking full renovations have access to additional programs though the landscape has shifted significantly in the past two years, and it’s important to know what’s currently active versus what has closed.
Canada Greener Homes Grant and Loan — Both closed
Both the Canada Greener Homes Grant and the Canada Greener Homes Loan are now closed to new applicants. The grant closed to new applicants in February 2024. The loan’s final application date was October 1, 2025. If you did not have an active application before those deadlines, neither program is available to you. Any source still presenting these as programs you can apply for in 2026 is providing outdated information.
What replaced it New active programs under the Canada Greener Homes Initiative
The federal government has launched two newer programs under the same initiative that are currently open.
The Canada Greener Homes Affordability Program
The Canada Greener Homes Affordability Program is designed for low-to-median income homeowners and is delivered through provincial and territorial partners. It covers the full cost of recommended retrofits for eligible households meaning no out-of-pocket expense to participate. For qualifying homeowners undertaking a full renovation that includes energy upgrades, this program could cover mechanical and insulation components entirely.
The Oil to Heat Pump Affordability Program
The Oil to Heat Pump Affordability Program is open for applications and offers up to $10,000 federally to eligible homeowners currently heating with oil who transition to a qualifying heat pump. In participating provinces and territories where the program is co-delivered, grants of up to $25,000 are available. For full home renovations that include heating system replacement, a standard component of a complete renovation this is an actively available funding source worth investigating early.
Enbridge Home Efficiency Rebate Plus (HER+) — Closed
Enbridge Gas’s HER+ program, which had been co-delivered with the federal Greener Homes Grant in Ontario, closed intake of new applicants in February 2024. Homeowners who completed a pre-retrofit EnerGuide evaluation before that date may still be processing their rebates. For new renovation projects beginning in 2026, this program is no longer available as a standalone rebate.
City of Toronto Home Energy Loan Program (HELP)
For homeowners in Toronto specifically, the City’s Home Energy Loan Program provides low-interest financing for energy efficiency improvements through a local improvement charge on the property tax. This is a financing mechanism rather than a grant, but it makes large energy upgrades more accessible by tying repayment to the property rather than the individual. If you sell the home, the remaining balance transfers to the new owner. For a full home renovation that includes energy upgrades, HELP removes the barrier of large upfront capital for that component of the project.
Municipal secondary suite incentive programs across the GTA
Several municipalities across the Greater Toronto Area have introduced or expanded programs to encourage the creation of legal secondary suites, in response to the provincial housing supply crisis.
These programs vary by city and are updated frequently, but common offerings include:
Municipalities with active or recently announced programs include Toronto, Mississauga, Markham, Vaughan, Richmond Hill, and Aurora, among others. The specifics change: some programs are first-come, first-served and run out of funding mid-year. The key implication for renovation planning is this: municipal programs for secondary suites almost always require pre-approval before construction begins. If you’re planning a full basement renovation that will include a legal secondary suite, initiating the municipal process early before any work starts is both a financial and logistical necessity.
Ontario’s Home Accessibility Tax Credit
While this credit is typically associated with smaller accessibility modifications, it’s worth mentioning in the context of a full home renovation. The Home Accessibility Tax Credit provides a 15% non-refundable federal credit on up to $20,000 in eligible accessibility expenses, a maximum credit of $3,000 per year. For homeowners whose full renovation includes accessibility features (wider doorways, roll-in showers, ramp access, barrier-free thresholds), these expenses can be claimed separately under this credit, even if the broader project is being claimed under other programs. Note that the same expenses cannot be claimed under both the Home Accessibility Tax Credit and the MHRTC.
How Much Can Ontario Homeowners Realistically Recover on a Full Home Renovation Through Credits and Rebates Combined?
Key Takeaway: On a full basement renovation creating a legal secondary suite ($95,000 – $125,000 range), realistic combined recovery from the MHRTC and Ontario HST rebate is $10,000 – $20,000+; on a whole-home gut renovation ($175,000 – $250,000 range), the Ontario HST rebate alone can recover $12,000 – $24,000+.
This is the question that matters most to any homeowner planning a serious renovation investment, and it deserves a concrete answer rather than a vague list of program names. The following are two realistic stacking scenarios for GTA homeowners, based on program parameters current as of 2026. These are illustrative calculations; actual amounts depend on your project’s specific scope, eligible expenses, home fair market value, and CRA filing outcomes. Always work with a qualified tax professional to model your specific situation.
Scenario A: Full Basement Renovation Legal Secondary Suite ($95,000 – $125,000 project)
A homeowner in North York is renovating a previously unfinished basement into a complete, permit-compliant legal apartment for their 68-year-old father-in-law. The project involves full framing, electrical, plumbing, insulation, drywall, flooring, a complete kitchen, a bathroom, a separate entrance, and all finishes. Total eligible renovation costs: $110,000.
Realistic combined recovery on this scenario: MHRTC: $7,250 + Ontario HST rebate: up to $6,600 + potential municipal incentives: variable Conservative total recovery: $10,000 – $20,000+
Scenario B: Whole-Home Gut Renovation ($175,000 – $250,000 project)
A family in Etobicoke is completing a full interior gut renovation of a 1960s detached home stripping all habitable areas to structure, rebuilding all systems, and fully finishing every room including the basement. Total eligible renovation costs: $210,000.
HST rebate (Ontario provincial component): The project clearly meets the 90% substantial renovation threshold. Ontario HST paid on the provincial component (8%) of $210,000 in eligible costs is approximately $16,800. At 75% rebate, the Ontario provincial portion returns approximately $12,600. The federal component may be limited or unavailable depending on the home’s post-renovation fair market value (the federal rebate phases out between $350,000 – $450,000 in home value, and most GTA homes exceed this threshold after a full renovation).
Realistic combined recovery on this scenario: Ontario HST rebate: up to $12,600. Conservative direct recovery: $12,000 – $24,000+
The stacking principle
The consistent pattern across both scenarios is that maximum financial recovery comes from combining programs rather than relying on any single one. The MHRTC and HST rebate can be used together on the same project (with careful expense allocation). Municipal programs layer on top of federal ones. Energy loan programs reduce the financing cost on work already planned.
The other consistent pattern: every program that matters at full renovation scale requires documentation, permits, and licensed contractors. Informal arrangements, cash payments, and unpermitted work don’t just create legal risk; they eliminate the financial recovery that makes a full renovation investment even more compelling.

What Mistakes Do Ontario Homeowners Make When Trying to Claim Renovation Tax Credits?
Key Takeaway: The costliest mistakes are starting work before confirming program eligibility, skipping permits, using unregistered contractors, and misunderstanding the 90% substantial renovation threshold each of these can eliminate $10,000 – $24,000+ in otherwise recoverable rebates.
Understanding what programs exist is only half the picture. The other half is avoiding the mistakes that disqualify claims, trigger audits, or eliminate recovery entirely. These are the errors that come up most frequently in the context of full renovation projects in Ontario.
Starting work before confirming program eligibility
Some programs, particularly municipal secondary suite incentive programs require pre-approval before construction begins. If you start the renovation and then apply, you may be ineligible. This applies regardless of how much money you’ve already spent. The rule exists because the programs are designed to incentivise decisions, not reward work already underway. For any renovation where you intend to claim a specific rebate or incentive, confirm program requirements and apply before the first nail is driven.
Not pulling permits
This is the single most consequential mistake a homeowner can make. Unpermitted renovation work disqualifies the HST rebate claim. It creates potential CRA audit exposure if the rebate is claimed anyway. It may require costly remediation if the municipality discovers the work during a future sale or inspection. And it undermines the documentation record that every program in this article depends on. Full renovations in Ontario particularly those involving structural work, new plumbing, new electrical, or the creation of secondary suites require permits. Working with a contractor who obtains the necessary permits is not a bureaucratic formality; it is a financial prerequisite.
Using unregistered or cash-payment contractors
CRA requires that renovation expenses be supported by invoices from registered businesses with a valid GST/HST number. Invoices must clearly itemise labour, materials, and HST charges. Cash payments with no paperwork, or invoices from contractors operating without registration, are not eligible for any of the programs discussed in this article. This is a particular risk in the renovation market, where informal arrangements are not uncommon. For a $100,000+ full renovation project, the difference between proper documentation and informal arrangements can mean $10,000 – $24,000+ in lost rebates.
Misunderstanding what counts as a “substantial renovation”
Homeowners sometimes assume that because their renovation was expensive, it qualifies. Expense is not the CRA’s criterion scope is. A $60,000 kitchen renovation that replaces everything within the kitchen but leaves the rest of the home untouched does not meet the 90% threshold, regardless of cost. The 90% test is calculated against the total habitable square footage of the dwelling, not the renovation budget. For homeowners whose project is borderline, working with a tax professional before filing rather than after to assess whether the threshold is met is strongly advisable.
Missing the self-contained unit requirement for the MHRTC
The most common reason MHRTC claims are denied is that the secondary unit created doesn’t meet the CRA’s four-component requirement: separate entrance, kitchen, bathroom, and sleeping area. All four must be present. Renovating a basement to add a bedroom and bathroom for a parent who will use the main floor kitchen does not qualify. The unit must function independently. This is a design and planning decision, not just a tax decision; it needs to be embedded in the renovation scope from day one.
Claiming expenses under multiple programs without proper allocation
The MHRTC and the Home Accessibility Tax Credit cannot use the same expenses. The MHRTC and the HST rebate require careful expense allocation. Claiming the same dollars under multiple programs is a CRA audit risk. The solution is not to avoid stacking programs — the solution is to work with a tax professional who can allocate expenses correctly across claims from the outset.
Waiting too long to file
The HST rebate must be filed within two years of completing the renovation. The MHRTC is claimed on the return for the tax year when the renovation period ends. Missing these windows means forfeiting the claim entirely, regardless of eligibility. Given that full renovation projects can span multiple tax years, tracking when the “renovation period” officially ends under CRA rules and filing accordingly is not something to leave until tax season after the fact.
