Every municipality calls this rebate something different.
One search can surface 'Protective Plumbing Program', 'Basement Flooding Prevention Program', or two different cities sharing 'Basement Flooding Protection Subsidy Program'. Which program applies depends on the municipality that serves your property — not the name in the search result. Use the table below to match the program name to your city, then route to the right city guide.
City rebate summary
Rebate programs across Canada are municipal or regional, and they differ in three structural ways: how they pay (percentage of cost vs flat maximum), whether they require an approved or pre-qualified contractor list, and whether pre-approval is required before work starts. Percentage programs include Toronto (80% up to per-measure caps), Peel (60% up to $1,500), London (90% up to category caps), and Halton (50% up to $1,600); flat-maximum programs include Windsor (up to $3,500), Edmonton (up to $800), and Mississauga (up to $7,500). Final eligibility always belongs to the official municipal or regional program.
Before starting work
Confirm which municipality or region actually serves your property — not the one a search result, a neighbour, or a contractor assumes.
Main eligibility risk
Assuming a neighbouring city's rules apply — rebate rules are municipal or regional, and the same program name can mean different rules.
Three Decisions That Decide What You Actually Get
Percentage of cost vs flat maximum
Percentage programs: Toronto (80% up to per-measure caps), Peel (60% up to $1,500), London (90% up to category caps), Halton (50% up to $1,600). Flat-maximum programs: Windsor (up to $3,500, e.g. $1,450 for a valve), Edmonton (up to $800), Mississauga (up to $7,500 across measures).
The headline dollar figure alone does not tell you what you get — the same $1,500 means 60% of cost in Peel and a flat cap in Mississauga.
Approved or pre-qualified contractor list
Hamilton is the exception in this hub: its maximum grant path can depend on the City's pre-qualified contractor list.
Halton and EPCOR explicitly keep no approved list — you choose your own licensed plumber. Toronto and Windsor require municipal contractor licensing instead of a list.
Pre-approval before work starts
Mississauga, Windsor, and London all require approval before construction starts. Toronto and Peel run permit-first, application-after-work paths with deadlines.
Starting work before a required pre-approval is the fastest way to lose eligibility. Confirm the order of operations on the official page for your city.
What To Do Before Starting Work
- 1Confirm which municipality or region actually serves your property — not the one a search result, a neighbour, or a contractor assumes.
- 2Find your city's official program name: Toronto and Windsor share one name, and Mississauga has two different programs (City stormwater and Peel sanitary).
- 3Check whether the program pays a percentage of cost or a flat maximum before you budget the out-of-pocket amount.
- 4Check whether an approved or pre-qualified contractor list is required — Hamilton has one; Halton and EPCOR explicitly do not.
- 5Check whether pre-approval is required before work starts — Mississauga, Windsor, and London require it.
- 6Keep the invoice, permit, inspection sign-off, and application documents the official program lists, and never assume approval is guaranteed.
Mistakes That Can Kill Eligibility
Assuming a neighbouring city's rules apply — rebate rules are municipal or regional, and the same program name can mean different rules.
Treating sanitary and storm rebates as interchangeable — Peel subsidizes sanitary valves, while Mississauga's City rebate is stormwater-oriented.
Starting work before a required pre-approval — Mississauga, Windsor, and London each require approval before construction.
Hiring outside a required contractor list — Hamilton's maximum grant path can depend on the City's pre-qualified list.
Applying to the wrong level of government — Peel Region, the City of Mississauga, and Halton Region each run separate programs.
Assuming the same program name means the same rules — Toronto and Windsor both call it 'Basement Flooding Protection Subsidy Program' but run different programs.

Permit / Inspection / Licensed Contractor Notes
- Order of operations varies: Mississauga and Windsor require approval before work, London requires written approval before construction, and Toronto and Peel run permit-first, apply-after-work paths.
- Contractor rules are municipal-specific: Toronto requires City business licences, Windsor requires a City-licensed plumber, Hamilton has a pre-qualified list, and Halton and EPCOR keep no list.
- Final eligibility always belongs to the official city or region — not this site, and not a contractor's claim.

Contractor Checklist
- Ask which rebate program the proposed work relates to: municipal storm, regional sanitary, or no rebate.
- Confirm who applies for permits and who books the final inspection.
- Get an itemized quote that separates labour, materials, taxes, camera inspection, and each flood-prevention measure.
- Ask whether the contractor will provide sketches, licence numbers, invoices, photos, and inspection documents where the official program requires them.
- Confirm the contractor will not start work until pre-approval is received where pre-approval is required.
- Ask how they determine sanitary vs storm lateral connections before recommending a valve.
- Keep every invoice, permit, inspection result, application email, and paid-in-full receipt.

FAQ
What is the residential protective plumbing program?
Protective plumbing is the general term for work that protects a home against sewer backup and basement flooding — typically backwater valves, sump pumps, and drain disconnection. No single national program carries that name. Hamilton's official program is literally called the Protective Plumbing Program, while other municipalities fund the same work under different names — Toronto's is the Basement Flooding Protection Subsidy Program. Check the comparison table on this page to find the program name for the municipality that serves your property, then confirm the current rules on that city's official page.
Is protective plumbing the same as a backwater valve rebate?
Not exactly — a backwater valve is one protective plumbing measure among several. Some programs fund other measures at higher amounts than the valve: in Mississauga, the sump pump is worth up to $6,000 against $1,500 for a storm lateral backwater valve. Which measure is worth the most varies by municipality, so check the comparison table and the official program page for your city before deciding what to install.
Why does every city call this program a different name?
Because each municipality and region runs its own program. Toronto and Windsor both use 'Basement Flooding Protection Subsidy Program', Hamilton uses 'Protective Plumbing Program', Halton uses 'Basement Flooding Prevention Program', and Edmonton's runs through EPCOR. The program name in a search result tells you almost nothing about which city it applies to — confirm the municipality that serves your property.
Toronto and Windsor share a program name — are the rules the same?
No. Both call it 'Basement Flooding Protection Subsidy Program' but they are separate programs with separate rules. Toronto pays up to $6,650 per property with City business licence requirements; Windsor pays up to $3,500 lifetime with approval-before-work and a City-licensed plumber. Confirm the city, not the name.
Do I have to use a specific contractor?
It depends on the municipality. Hamilton's maximum grant path can depend on the City's pre-qualified contractor list. Halton and EPCOR explicitly keep no approved list. Toronto requires City business licences and Windsor requires a City-licensed plumber. Check the official program page for your city before hiring.
Can I start work and apply later?
Only where the program allows it. Mississauga, Windsor, and London require approval before construction starts. Toronto and Peel run permit-first, application-after-work paths with deadlines. Starting early under the wrong rules can kill eligibility.
