- 3For backwater valves, obtain a building permit and inspection.
- 4Confirm downspouts are disconnected from the City's sewer system or that an exemption applies.

Mistakes That Can Kill Eligibility
Using an unlicensed contractor or subcontractor.
Covering or enclosing a backwater valve before inspection.
Missing the application deadline for the date category your work falls under.
Assuming downspout disconnection itself is subsidized.
Not checking whether the property has already reached its lifetime subsidy maximum.
Backwater Valve vs Sump Pump vs Foundation Drain Work
| Measure | Best for | Rebate watchout |
|---|---|---|
| Sanitary backwater valve | Reducing risk of sewage backup through the sanitary lateral. | Often requires a permit and inspection. Shared laterals, basement apartments, or the wrong lateral can affect eligibility. |
| Storm backwater valve | Reducing risk of storm sewer backup where the home has a storm lateral connection. | Do not assume a sanitary valve and storm valve qualify under the same program. |
| Sump pump and pit | Collecting foundation drain water and pumping it away from the home. | Discharge location, downspout disconnection, and new vs replacement equipment rules matter. |
| Foundation drain or weeping tile work | Redirecting water away from the sanitary/storm system or correcting drainage at the foundation. | Some programs cover disconnection/capping but not new waterproofing, crack repair, or interior finishes. |
Permit / Inspection / Licensed Contractor Notes
- Toronto requires a building permit for backwater valve installation.
- Toronto requires contractor and subcontractor business licences at the time of installation or service.
- The City may need access to verify a backwater valve installation.

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, and photos required by the city.
- 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.
