Mississauga Flood Prevention Rebates: Get Up to $10,500 (Guide)

Mississauga homeowners can get up to $10,500 back from the City for flood-proofing their homes, through two programs announced in February 2025: the Basement Flooding Prevention Rebate and the Flood Resilience Rebate. If your basement has flooded before, or you live in an area that saw flooding in the July 2013 or July 2024 storms, these programs are worth knowing about. Program details can change, so always confirm current amounts and rules on the City of Mississauga website before you book work.

1. Basement Flooding Prevention Rebate (up to $7,500)

This rebate helps pay for measures that stop water from getting into your basement in the first place. Eligible work must be done by a licensed professional and can include:

• Backwater valve installation on the main sewer line, which stops sewage from backing up through floor drains
• Sump pump installation
• Downspout disconnection from the sewer system
• Related plumbing work such as capping a foundation drain connection

2. Flood Resilience Rebate (up to $3,000)

This rebate is for homeowners who have already experienced flood damage (on or after July 8, 2013) and rebuild using water-resistant materials, covering up to 50% of eligible costs. Think of it as “build back better”: when your basement is restored after a flood, choosing materials that tolerate water can reduce the damage next time. Examples include:

• Moisture-resistant or cement board instead of standard drywall at the bottom of walls
• Closed-cell spray foam or mineral wool instead of fibreglass batts
• Luxury vinyl plank or tile instead of carpet or laminate
• PVC or composite baseboards instead of MDF

Who Is Eligible?

• Owners of detached, semi-detached, duplex or townhouse homes in Mississauga
• The applicant must be the registered owner; proof is usually your City tax bill
• Work must meet program rules, and some measures need a licensed plumber and permits

How to Apply

1. Read the current program guide on the City of Mississauga website.
2. Get quotes from licensed contractors.
3. Complete the work and keep all invoices and photos.
4. Apply online or by mail with your tax bill, invoices and supporting documents.

Why Prevention Pays

A single sewage backup cleanup in a finished basement can cost $12,000 to $35,000 or more, and many basic insurance policies don’t cover it without a sewer backup endorsement. A backwater valve costs a fraction of that, and the rebate covers a large share. Learn more about water damage costs and insurance coverage.
