Ontario Renovation Rebates Finder: Programs to Check for Your Project

Toronto (including Etobicoke, North York and Scarborough)

Basement Flooding Protection Subsidy: up to $6,650 per property. The City pays 80% of each invoiced item for work completed on or after November 12, 2025: a home plumbing assessment (up to $500), up to two backwater valves (up to $1,600 each), a sump pump (up to $2,250), a battery backup (up to $300) and weeping-tile severance and capping (up to $400).

• Who qualifies: the registered owner of a single-family home, duplex, triplex or fourplex in Toronto, with no outstanding City taxes or debts. Downspouts must be disconnected, or you need a City exemption.
• Rules that decide it: the contractor and every sub-contractor must hold a valid City of Toronto business licence in a class the program accepts for that item. A backwater valve needs a building permit and an inspection before it is covered.
• How to apply: online after the work, within two years of installation, with itemized invoices marked paid in full. Processing can take up to 10 weeks; funding is first come, first served.

Development charges: creating additional dwelling units in an existing house is exempt from development charges as prescribed by provincial legislation. Laneway and garden suites use a separate deferral program, which delays payment rather than waiving it.

How we help: we plan the flood work and the suite as one scope, pull the permits, book the inspections and give you itemized, paid-in-full invoices and photos for the application. Check the licence class for each item before work starts; the City decides eligibility. Find out what I qualify for. Related: Toronto flood subsidy, step by step.

Peel: Mississauga, Brampton, Caledon and Bolton

Peel Region Backwater Valve Rebate: 60% of the invoice, up to $1,500 including tax. For a backwater valve on the sanitary lateral. Get a building permit from your city before installing, pass the municipal inspection, then send the application form with the documents by email or mail. Peel reviews within 5 business days and mails the cheque in 4 to 6 weeks.

Mississauga Basement Flooding Prevention Rebate: up to $7,500. Sump pump up to $6,000; foundation-drain capping up to $1,000; downspout disconnection $125 each, up to $500; a backwater valve on the storm lateral up to $1,500 (downspouts must also be disconnected).

• Who qualifies: an individual registered owner of a detached, semi-detached, duplex or townhouse in Mississauga, with no City sump-pump rebate in the last 10 years. The work must be done by a contractor licensed in their trade.
• Rule that decides it: every measure must be pre-approved before work starts, with an itemized quote, a contractor sketch and any required permit. Apply for final approval within six months of pre-approval with the paid invoice.

Mississauga second, third and fourth units: the City refunds the building-permit fee by cheque once construction and inspections are complete. Second and third units are exempt from City, Region and GO Transit development charges; school-board charges may still apply.

Caledon and Bolton, Gentle Density Community Improvement Plan: an Affordable Unit Grant of up to $30,000 for homeowners creating or legalizing an additional residential unit, with a commitment to affordable rent. The plan runs until December 31, 2028; applications are reviewed first come, first served, subject to eligibility and funding.

Brampton: we found no Brampton-only renovation subsidy on November 7, 2026. The Peel backwater-valve rebate and the provincial and federal programs above apply.

How we help: we get the pre-approval paperwork right before work starts, then deliver the permit, inspection and itemized invoices the rebate asks for. Find out what I qualify for. Related: legal basement apartments in Brampton.

Halton: Oakville, Burlington, Milton and Halton Hills

• Wastewater lateral lining and repair: 50%, up to $4,000
• Backwater valve installed inside the home: 50%, up to $1,600

Rules that decide it: you must own the property; each subsidy is paid once per property; permits and passed inspections are required for the plumbing work; the sump-pump and drain items need proof of a stormwater connection (a household drainage survey or a licensed plumber’s assessment); downspouts must be disconnected; water-powered backup pumps don’t qualify. How to apply: after the work, send the signed application, waiver, sketch and documents to the Region by email, mail or in person. Payment usually follows 4 to 6 weeks after the signed waiver. The Region can end the program at any time.

How we help: we sequence the waterproofing, sump pump and valve inside the basement scope, handle permits and inspections, and give you the photos and itemized invoices the form asks for. Find out what I qualify for.

Durham: Ajax, Pickering, Whitby, Oshawa and Bowmanville

Whitby, Additional Dwelling Unit Incentive Program: a one-time reimbursement of select Town fees for a new additional dwelling unit, where applicable: the ADU building-permit fee, the ADU registration inspection fee, the curb-cut fee, the below-grade entrance fee and education development charges for detached ADUs. The Town does not publish dollar amounts.

Hamilton and Stoney Creek

Protective Plumbing Program: a grant of up to $2,000 for a backwater valve and other eligible work when you use a contractor from the City’s pre-qualified list (up to $500 for the valve with a contractor not on the list). A sump pump qualifies only together with a backwater valve.

• Who qualifies: the owner of a single-family home with a basement, connected to City sewers, built before January 1, 2012, with property taxes up to date and not in the process of adding a secondary dwelling unit.
• How to apply: confirm eligibility with the City (905-546-2489), have a pre-qualified contractor assess the home, the contractor takes out the permit, the work is inspected, then the completed package goes to the City.

Additional Dwelling Unit and Multi-Plex Housing Incentive Program: the City’s page says the application portal is closed to new submissions. Don’t budget a new unit around it.

How we help: a new suite rules out the 3P grant while it is in progress, so we plan flood protection and suite timing together. Find out what I qualify for.

Kitchener, Cambridge, Guelph and Brantford

Kitchener, Missing Middle and Affordable Housing Community Improvement Plan (Additional Dwelling Unit Grant): grants that cover all or part of the development charges on new ADUs. The first and second ADUs get 100% of education development charges; a third ADU gets 50% of City, Regional and education charges, or 100% with commitments such as one affordable unit for 5 years. For units with building permits issued on or after January 5, 2026, reviewed first come while funding is available.

Cambridge, Additional Residential Unit grant: up to $10,000, one time, for owners who have built an ARU, toward sanitary or water service upgrades, professionally prepared permit drawings and hard construction costs.

The City and Region do not collect development charges for ARUs (school boards may).

Guelph and Brantford: we found no current municipal renovation subsidy on an official page on November 7, 2026. The provincial and federal programs above apply.

Barrie

2026 Additional Residential Unit Incentives Program: building-permit application fees for a new unit (including zoning and water fees) are cut by 50%, and a further 50% may be rebated if the unit reaches occupancy or final interior inspection within 12 months of permit issuance. It covers a second, third or fourth unit in a detached, semi-detached or street townhouse, and detached units, for applications submitted on or after January 1, 2026. Development charges are not included.

How we help: the second 50% depends on finishing within 12 months, so we schedule the build from the permit date. Find out what I qualify for.
