The halton region basement flooding subsidy program gives residential homeowners across Oakville, Burlington, Milton, and Halton Hills up to $8,175 in reimbursements for flood-prevention upgrades — and most homeowners have no idea it exists. If youre already dealing with water in your basement, call our 24/7 emergency team at (289) 724-9139 for immediate response while you read this.
We’re writing this from the cleanup side. Our crews respond to basement floods throughout Halton Region every week, and we’ve seen alot of homes that could have cut their risk — or their out-of-pocket costs — significantly with a prevention upgrade backed by this subsidy. This guide breaks down every covered measure, the exact reimbursement amounts, who qualifies, and how to apply.
What Is the Halton Region Basement Flooding Subsidy Program?
The halton region basement flooding subsidy program is a reimbursement-based initiative administered by Halton Region Public Works. Its designed to help homeowners reduce the risk of basement flooding by subsidising four specific flood-prevention installations. Eligible homeowners are reimbursed either 50% or 100% of their installation costs, up to a combined maximum of $8,175 across all four measures.
The program applies region-wide — Oakville, Burlington, Milton, and Halton Hills all qualify. You dont need to have experienced a flooding event to apply; preventive installations are fully eligible. After the July 2024 storms that triggered more than 1,600 basement flooding reports in Burlington alone and caused widespread damage in Georgetown, Halton Region fast-tracked over 600 applications in the months that followed. The demand reflects just how serious flooding pressure has become in this region.

The 4 Subsidy Categories: How Much Can You Receive?
Heres exactly what the halton region basement flooding subsidy program covers, with amounts confirmed from Halton Region’s September 2025 program update:
1. Sump Pump Installation — Up to $5,000 (100% Reimbursement)
This is the largest single benefit the program offers. Halton Region reimburses 100% of eligible costs, up to $5,000, for a new sump pump installation — provided the work includes weeping tile disconnection from the wastewater sewer system. A properly sized submersible pump with a battery backup is the single most effective defence against basement flooding, and for most Halton homes it’s now fully funded through this program.
Our team frequently responds to flood calls where the sump pump was undersized, past its 7-to-10-year lifespan, or failed during a power outage. After our crews complete a basement flood cleanup, we always recommend getting this upgrade done before the next storm season. At full reimbursement, there’s no reason to wait. For more on what happens when pumps fail, see our sump pump failure guide for Halton homeowners.
2. Downspout Disconnection — Up to $500 (100% Reimbursement)
Halton Region reimburses 100% of eligible costs up to $500 for downspout disconnection — rerouting your eavestroughs to discharge onto the lawn or into a rain barrel rather than directly into the municipal sewer system. This reduces stormwater volume entering the combined sewer and lowers your risk of sewage backup during heavy storms. It’s a relatively straightforward installation that qualifies for full reimbursement and is often the first step required before the backwater valve subsidy becomes available.
3. Backwater Valve Installation — Up to $675 (50% Reimbursement)
A backwater valve is a one-way gate installed in your home’s main drain line that prevents sewage from flowing backwards into your basement when the municipal sewer becomes overloaded. Halton Region reimburses 50% of eligible costs up to $675. One important condition: you wont qualify for this backwater valve subsidy unless your downspouts and weeping tile are already disconnected from the wastewater sewer upstream of the valve — so downspout disconnection typically comes first.
If you’ve already experienced sewer backup, our sewer backup cleanup team responds 24/7 for extraction, biohazard decontamination, and structural drying across all of Halton Region.
4. Sewer Lateral Lining or Repair — Up to $2,000 (50% Reimbursement)
Halton Region reimburses 50% of eligible costs up to $2,000 for lining or repairing the private sewer lateral — the underground pipe running from your home to the municipal main. Cracked or deteriorated laterals allow groundwater infiltration and create points of failure during high-flow events. This measure typically involves a licensed plumber performing a camera inspection before the lining is applied, and requires a building permit in most Halton municipalities.
Who Qualifies for the Halton Region Basement Flooding Subsidy Program?
To be eligible for the halton region basement flooding subsidy program, your property must meet all of the following conditions:
- You are the registered owner of a residential property within Halton Region (Oakville, Burlington, Milton, or Halton Hills)
- All work is completed by a licensed Ontario contractor — DIY installations do not qualify
- You apply within one year of the installation date
- For the backwater valve subsidy specifically: your downspouts and weeping tile must already be disconnected from the wastewater sewer upstream of the valve
- Required permits are obtained where applicable
The program is reimbursement-based — you pay the licensed contractor first, then submit your invoices and documentation to Halton Region for review. Reimbursement cheques are typically issued within 4 to 6 weeks of a complete and approved application. Conservation Halton also maintains flood risk mapping resources that can help homeowners assess their property’s specific exposure before deciding which upgrades to prioritise.
How to Apply: Step by Step
- Confirm your property is in an eligible Halton Region municipality (Oakville, Burlington, Milton, or Halton Hills)
- Get quotes from a licensed Ontario plumber or contractor for one or more of the four covered measures
- Obtain any required building permits from your municipality before the work starts
- Have the installation completed and retain all invoices and contractor licence documentation
- Download and complete the application form from the Halton Region program page
- Submit your complete package — form, invoices, permits, and contractor information — to Halton Region Public Works
- Receive your reimbursement cheque within approximately 4 to 6 weeks
Apply as soon as the work is done. The one-year window from installation date can pass quickly, and program funding levels can change.

Why Halton Homes Are at Greater Risk Than Most Homeowners Realise
Halton Region isn’t just an area with occasional rainy seasons — its geography and aging infrastructure create real, measurable flood pressure on residential foundations across all four municipalities.
The July 2014 Burlington flash flood delivered 191mm of rain in roughly two hours, flooding thousands of basements and overwhelming the combined sewer system across Burlington and parts of Oakville. A decade later, the July 2024 storms generated more than 1,600 basement flooding reports from Burlington alone, with Georgetown hit hard and power outages compounding sump pump failures throughout Halton Hills. These weren’t once-in-a-generation events — they happened ten years apart, and the frequency of severe summer storms is increasing.
The infrastructure risk is concentrated in older neighbourhoods. Aldershot in Burlington sits on a combined sewer system with a high water table. Old Milton — homes built from the 1950s to 1980s south of Derry Road — shares the same combined sewer vulnerability. Kerr Village in Oakville deals with aging pipes and proximity to Lake Ontario’s groundwater influence. Properties near Sixteen Mile Creek, Bronte Creek, and the Credit River system face overland flood pressure every spring thaw. For flood risk mapping by neighbourhood, Conservation Halton maintains watershed-level data for the entire region.
This is precisely why the halton region basement flooding subsidy program exists. The Insurance Bureau of Canada estimates the average Ontario water damage claim runs close to $43,000. A $5,000 sump pump that prevents one flood event pays for itself many times over — and through this program, that sump pump costs you nothing.
How Halton Water Damage Restoration Helps After a Flood
When flooding happens — before or after your prevention upgrades are in place — our team responds across Halton Region with truck-mounted extraction equipment and industrial drying systems. We handle emergency water removal, structural drying and moisture mapping, mold prevention with antimicrobial treatment, full insurance documentation, and reconstruction where needed.
We work directly with insurance adjusters and can help you understand whether your claim covers a sewer backup, overland flooding, or a burst pipe event — each is handled differently by Ontario insurers. Call (289) 724-9139 any time, day or night, for 24/7 emergency response across Oakville, Burlington, Milton, and Halton Hills.
Frequently Asked Questions About the Halton Region Basement Flooding Subsidy Program
What is the maximum total available through the halton region basement flooding subsidy program?
The maximum combined reimbursement is $8,175, which requires qualifying for all four categories: sump pump installation ($5,000), downspout disconnection ($500), backwater valve ($675), and sewer lateral lining or repair ($2,000). Most homeowners access one or two categories per application, with the sump pump subsidy being by far the most commonly claimed.
Does the subsidy cover cleanup costs after a flood?
No. The halton region basement flooding subsidy program covers prevention installations only — it does not reimburse cleanup, water extraction, drying, or repair work after a flood. Your home insurance policy is the primary funding source for post-flood restoration. Call our team at (289) 724-9139 and we’ll assist with the documentation your insurer requires.
Is there a separate grant if my flood was caused by a public sewer backup?
Yes. Halton Region also offers a separate Ex-gratia (compassionate) grant of up to $1,000 for homeowners whose basement flooded due to a public sewer backup event — meaning the municipal system overflowed into your home through no fault of your private plumbing. This is a distinct program from the prevention subsidy. Report the flooding to Halton Region by calling 311 within the required timeframe to start the compassionate grant process.
Do I need a building permit to install a backwater valve in Halton?
Yes, building permits are required for backwater valve installations in most Halton municipalities. Your licensed contractor typically handles the permit application. Note that the Town of Halton Hills has periodically waived permit fees for backwater valve and sump pump installations to encourage uptake — check with the Town of Halton Hills directly for any current fee waivers before your installation date.
Can I apply if my flooding happened during the July 2024 storms?
If you had prevention work completed after the July 2024 storms, you may still be within the one-year application window depending on when the installation was done. The program is ongoing. Contact Halton Region Public Works directly to confirm whether your installation date qualifies and whether any post-storm application extensions have been granted.
My sump pump failed during a storm and my basement flooded. What’s the first step?
The first step is emergency water removal, not paperwork. Call (289) 724-9139 for 24/7 emergency response. Once the immediate flooding is handled and drying is underway, our team can help you document the damage for your insurer and connect you with a licensed plumber for the replacement — so you’re set up to apply for the sump pump subsidy at the same time. Our sump pump failure guide covers what to check, what to tell your insurer, and when to escalate to a full basement flood cleanup.
