Mississauga homeowners continue to face the growing threat of basement flooding due to increasingly intense rainfall, aging infrastructure, and overloaded municipal drainage systems. To support residents in protecting their homes, the City of Mississauga has introduced two rebate programs in 2025: one focused on flood resilience after damage has occurred and another for proactive basement waterproofing services and flood prevention.
This blog outlines both rebate options, eligibility requirements, covered services, how to apply, and what to consider before getting started. As a Mississauga waterproofing contractor, we specialize in the installation of rebate-eligible flood protection systems. DGI Waterproofing staff ensures all the installations meet the standards set by the City to ensure homeowners are eligible for the rebate and at the same time get the best in waterproofing.
Option 1: Flood Prevention Rebates
This rebate is designed for homeowners who’ve already experienced basement flooding. If you’ve had damage from heavy rain, whether that’s ruined flooring, soaked drywall, or worse, this program helps cover the cost of upgrades that make your home more resilient for the future.
You can receive 50% of your costs back, up to $3,000, for approved upgrades that make your basement more flood-resistant. This includes both interior improvements like waterproof flooring and moisture alarms and exterior work like improving the grading around your home or adding waterproof coatings to your foundation.
Who Is Eligible?
To qualify for this rebate:
- You must own a detached, semi-detached, duplex, or townhouse in Mississauga.
- You must be an individual homeowner (not a business or corporation).
- Your home must have experienced flooding due to heavy rainfall on or after July 8, 2013.
- You must not have any outstanding taxes, fees, or by-law issues with the City.
What Is Covered?
Some examples of eligible improvements include:
- Water-resistant flooring and wall materials
- Elevating electrical systems and HVAC
- Moisture sensors and alarms
- Re-grading the yard around your home to direct water away
- Exterior waterproof coatings or membranes
- Window well covers and other protective barriers
How To Apply
You’ll need to gather a few things:
- A copy of your most recent property tax bill
- Proof of flooding, like dated photos or insurance claims
- Paid receipts and documentation for the upgrades
Then, complete the application online through the City of Mississauga’s official Flood Resilience Rebate page. Applications are open until December 31, 2025, and are reviewed on a first-come, first-served basis.
Option 2: Basement Flooding Protection Rebates
While the resilience rebate is for homes that have already seen flood damage, this program is about prevention, stopping the water from getting in before it becomes a problem. With these rebates, it is now even easier to waterproof your basement in Mississauga!
The City is offering rebates for homeowners who install qualifying waterproofing systems, such as sump pumps, foundation drain capping, backwater valves, and downspout disconnections. These systems are designed to reduce the chance of flooding from both groundwater and municipal sewer backups. Many homeowners delay waterproofing projects due to cost concerns, but with the Mississauga Basement Flooding Prevention Rebate, up to $7,500 in financial assistance is available to help cover the expenses.
Who is Eligible?
To qualify for the Mississauga Basement Flooding Prevention Rebate Program, homeowners must meet specific eligibility criteria set by the City.
Eligible Homeowners:
- Be the registered owner of a detached, semi-detached, duplex, or townhouse in Mississauga
- Be an individual (not a corporation)
- Have no unpaid taxes or active municipal by-law violations
- Not have received a sump pump rebate in the past 10 years
What Is Covered?
The rebate program covers four key flood prevention methods. Below is a breakdown of the maximum rebate amount homeowners can receive for each measure.
Basement Flood Prevention Measure |
Maximum Rebate |
|
|---|---|---|
| 1 |
Sump Pump Installation |
$6,000 |
| 2 |
Foundation Drain (Weeping Tile) Pipe Capping |
$1,000 |
| 3 |
Downspout Disconnection |
$125 per downspout (up to $500 total) |
| 4 |
Storm Lateral Backwater Valve (Must also disconnect downspouts) |
$1,500 |
1. Install a New Sump Pump
One of the best ways of basement water damage prevention is a functioning sump pump system that proactively pumps away water before it accumulates. With a possible rebate of as much as $6,000 for installation, now is the time to purchase certified Mississauga professional sump pump installation and maintenance. Our knowledgeable crew provides high-end sump pump solutions, such as guaranteeing your system will be rebate eligible, as well as long-term waterproofing needs.
2. Disconnecting Underground Downspout Drainage Systems
A rebate of $125 per downspout (up to $500 maximum) is given when you disconnect your downspouts from the City’s storm sewer system. Instead of being connected to the City’s system, DGI can add an underground downspout extension, which will direct excess water away from your property without contributing to the large amounts of flood water channeling through the City’s storm system.
3. Install a Backwater Valve
A storm lateral backwater valve prevents municipal sewer water from flowing back into your home when it rains heavily. This is especially important in basements that are prone to flooding. Up to $1,500 in rebates are available to homeowners when they install a backwater valve and disconnect downspouts as part of their flood protection system.
How to Apply?
Applying for the rebate involves several steps to ensure compliance with the City’s regulations.
Step 1: Hire a Licensed Waterproofing Contractor in Mississauga
The City of Mississauga requires that all work is done by professionals who hold a valid City of Mississauga business licence. As a certified waterproofing contractor, DGI Waterproofing meets all those requirements, so when we do the job, you can be confident it qualifies.
Step 2: Get a Professional Waterproofing Assessment
Our team will assess your home to determine which flood prevention measures qualify for the rebate. We provide an itemized quote outlining the recommended work, materials, and costs.
Step 3: Submit the Rebate Application
Homeowners can apply for the rebate online through the City of Mississauga’s website or by mailing a completed application to the City’s Transportation and Works Department. The application must include:
- A copy of the latest property tax bill
- Detailed contractor invoices showing proof of installation
- Proof of payment for the completed work
Step 4: Rebate Approval & Processing
Once the City reviews the application, approved homeowners will receive their rebate check within 8-10 weeks. Rebates are issued on a first-come, first-served basis until funding runs out.
Things To Consider Before Applying For Mississauga Rebates
1. Keep all your paperwork.
Both programs require detailed documentation to approve your rebate. This includes:
- Proof of ownership (usually your property tax bill)
- Detailed, itemized quotes and final invoices
- Proof of full payment
- Before-and-after photos (if possible)
- Proof of prior flooding (for the Flood Resilience Rebate)
It’s a good idea to keep everything organized from day one. If you’re unsure what’s needed, we can help walk you through it.
2. Don’t delay your application.
Both rebates are first come, first-served, and once funding runs out, that’s it. Whether you’re applying retroactively or planning new work, it’s best to get your application in early, especially if you’ve already completed some work after July 2024.
3. Check if your property needs special consideration.
If you live in a townhouse or have a foundation tied into a sanitary sewer, there may be other procedures involved, like the need for pre-approval or speaking with the Region of Peel. We have dealt with these situations before and can walk you through them.
4. Not all costs are covered.
While these rebates are quite generous, they don’t cover everything. Cosmetic repairs like drywall, flooring, landscaping, or painting, for example, aren’t covered. Backup power sources and secondary sump pumps aren’t covered either.
Benefits of Applying for the Mississauga Flood Protection Rebates
- Reduces the cost of waterproofing solutions
- Protects homes from expensive flood damage and mold growth
- Increases property value by improving basement waterproofing
- Reduces insurance costs by lowering flood risk
Water damage restoration can be costly, making proactive flood prevention a smart investment.
