Short answer: there’s no general grant for finishing a basement in Ontario. Four programs can still put real money back when your basement work fits them:
– The federal Multigenerational Home Renovation Tax Credit: up to $7,250 when you build a self-contained suite for a parent, grandparent or adult relative with a disability.
– Toronto’s Basement Flooding Protection Subsidy: up to $6,650 for a backwater valve, sump pump and related plumbing work.
– The federal Home Accessibility Tax Credit: on up to $20,000 of safety and access work for someone 65+.
– Home Renovation Savings rebates: for insulation, windows and heat pumps.
For accessibility or energy work elsewhere in the house, use the Ontario renovation rebates finder to identify official programs and conditions to check.
Most of these have a rule you must meet before the work starts, so check them at the planning stage, not after.

Amounts are the programs’ maximums, checked on October 1, 2026. Each program decides your eligibility. Rules change, so open the official link before you rely on a number.
1. Building a suite for a parent: the Multigenerational Home Renovation Tax Credit
This is the biggest one for basement work, and the one most homeowners miss.
What it pays: a refundable federal tax credit. On a 2025 return, CRA lists 14.5% of up to $50,000 of eligible costs, so up to $7,250. “Refundable” means you get it back even if you owe little tax.
The rate follows the lowest federal tax rate, which drops to 14% for 2026. A renovation finished in 2026 therefore works out to about $7,000 at most. CRA will confirm when the 2026 forms come out.
Who it’s for:
– A qualifying individual: someone 65 or older by the end of the year, or an adult (18–64) who is eligible for the disability tax credit.
– A qualifying relation they live with: an adult child, grandchild, parent, grandparent, sibling, aunt, uncle, niece or nephew.
What the basement must become: a self-contained unit with its own private entrance, kitchen, bathroom and sleeping area. A finished family room or a bedroom with a bathroom doesn’t qualify. A legal basement suite usually does, because those four pieces are what a legal suite needs anyway.
Rules that trip people up:
– Both of you must be living in the home (or be reasonably expected to) within 12 months after the work ends.
– One claim per qualifying individual, for life.
– Eligible: permits, contractor labour, materials, equipment rental. Not eligible: appliances, furniture and routine repairs.
– Keep every receipt. Work done by a relative only counts if they’re registered for GST/HST.
Example: a Vaughan family builds a legal basement suite so a 70-year-old mother can move in. At least $50,000 of the cost is eligible work, so their 2025 claim is $7,250 back. A 2026 finish gives about $7,000.
2. Toronto: the Basement Flooding Protection Subsidy
If your basement has flooded, or your street has, this is the time to add protection, because the city pays most of it.
What it pays (work done on or after November 12, 2025): 80% of each item’s cost, up to:
| Item | City pays up to |
|---|---|
| Home plumbing assessment | $500 |
| Backwater valve (up to 2) | $1,600 each |
| Sump pump | $2,250 |
| Sump pump battery backup | $300 |
| Pipe severance and capping | $400 |
| Maximum per property | $6,650 |
Before work starts:
– The contractor (and any sub-contractor) must hold a valid City of Toronto business licence in a class the program accepts. The program page lists the classes: plumbing, plumbing and heating, drain, and building renovator for sump pump and pipe work only.
– Ask your contractor which licence covers which item, and check it yourself on the City’s licence lookup.
– Your downspouts must be disconnected, or you need a City exemption.
After the work:
– A backwater valve needs a building permit and an inspection.
– Keep itemized electronic invoices and photos (the sump pump discharge point is required).
– Apply within two years of installation. Payment can take up to 10 weeks.
Why do it during a basement renovation? The floor and walls are already open, so the plumbing work costs less than it would after the new flooring is down. And a finished basement without flood protection is the most expensive thing to redo.
3. Making the basement safe for someone 65+: the Home Accessibility Tax Credit
If a parent will use the basement, or you’re planning for your own later years, safety and access work can earn a federal tax credit.
What it covers: work that helps a person 65+ (or someone eligible for the disability tax credit) get around the home safely, or reduces their risk of harm. Typical basement examples:
– A walk-in or curbless shower and grab bars
– A safer stair with handrails on both sides and better lighting
– Wider doorways
– Non-slip flooring
How much: up to $20,000 of eligible expenses per year. It’s a non-refundable credit at the lowest federal rate: 14.5% for 2025, so up to about $2,900 off the tax you owe.
Not eligible: routine repairs and maintenance, appliances, and work done mainly to raise the home’s value.
4. Energy rebates: Home Renovation Savings
Basement work is often when foundation walls get insulated and old windows get replaced. Ontario’s Home Renovation Savings program (Save on Energy with Enbridge Gas) can rebate part of that:
– Insulation (attic, wall, foundation, exposed floor): up to $7,700, in the bundle that starts with a home energy assessment and includes two or more upgrades.
– ENERGY STAR windows and doors: $100 per rough opening, in the same bundle.
– Air sealing: up to $250.
– Heat pumps: up to $7,500 (cold-climate air source) as a single upgrade.
The key step: book the energy assessment before you insulate or close the walls. The “before” measurement is what qualifies the rebate. Check the program site for contractor and timing rules before you sign.
5. Toronto: no development charge for a basement apartment
Adding a second unit to an existing house in Toronto is exempt from development charges, which can otherwise run into the tens of thousands. You still need a building permit, and the suite must meet the Ontario Building Code (ceiling height, fire separation, exits). Other GTA cities have similar rules for additional units; check your city’s page before you budget.
What these programs don’t cover
- Finishing a basement for your own family use (open rec room, home gym, bedroom) has no general grant. The savings come from scope choices, which our basement cost guide explains.
- Appliances, furniture and décor, under any of the programs above.
- Work without receipts or permits where the program requires them.
How to plan so you don’t miss the money
- Decide the use first. A suite for a parent can qualify for the multigenerational credit. A rental suite can’t.
- Check “before work” rules: the energy assessment, the contractor licence for flood work, and permits.
- Ask for an itemized quote. Separate lines for the plumbing, the insulation, the windows and the accessibility items make claims easier and receipts cleaner.
- Keep everything: invoices, permits, inspection reports and photos.
- Claim at tax time: line 45355 for the multigenerational credit, line 31285 for the accessibility credit.

FAQ
Is there a government grant to finish a basement in Ontario?
Not a general one. Money back comes from targeted programs: the multigenerational credit for a family suite, Toronto’s flood subsidy, the accessibility credit for 65+, and energy rebates for insulation and windows.
Can I claim the Multigenerational Home Renovation Tax Credit for a rental basement apartment?
No. The suite must be for a qualifying individual (65+ or eligible for the disability tax credit) who lives in the home with a qualifying adult relative.
How much is the multigenerational credit for 2026?
For 2025 claims it’s 14.5% of up to $50,000, so $7,250. The rate follows the lowest federal tax rate, which is 14% for 2026, so about $7,000. Check CRA when the 2026 forms are released.
Does Toronto pay for a backwater valve?
Yes, up to $1,600 per valve (80% of the cost, up to two valves), as part of a maximum of $6,650 per property, for work done on or after November 12, 2025. It needs a permit, an inspection and a contractor with an eligible City of Toronto licence.
Do I pay development charges for a basement apartment in Toronto?
Additional units created in existing houses are exempt. A building permit is still required.
