An expanded subsidy with component limits
Toronto’s expanded amounts apply to eligible work completed on or after November 12, 2025; applications for those amounts began May 1, 2026. The maximums are 80% of eligible invoiced cost, subject to caps: $500 for a plumbing assessment, $1,600 per backwater valve for up to two devices, $2,250 for one sump pump, $300 for its battery backup and $400 for eligible drain severance and capping.
These are separate lifetime property limits, not a flat $6,650 payment. Older completed work has different caps. Registered owners of eligible Toronto single-family, duplex, triplex and fourplex homes must meet the city’s conditions. Submissions remain subject to annual funding; an application is not a guaranteed subsidy.
Diagnose the water pathway before selecting equipment
A wet basement can involve more than one route. Record when water appeared, whether rain or a sewer event coincided with it and where it entered. Give those observations to a qualified plumber. Ask which proposed device addresses that route and what it cannot prevent. A subsidy for a component is not evidence that the component is the right response to every basement problem.
The city’s plumbing-assessment form separates several observations about the property’s plumbing and drainage arrangements. Ask the plumber to explain the findings in language you can use when comparing proposals. Keep a copy of the completed form. Use our basement moisture guide to organize other questions before repairing finishes that may become wet again.

Check the property history and contractor before work
Ask the city whether the property has previously received a subsidy for the proposed measure. A new owner does not automatically mean a new lifetime allowance. Then verify the contractor and subcontractors through the city’s business-licence lookup linked on the program page. Toronto requires the relevant licence at the time of the work.
Prepare a small property checklist: ownership, outstanding city debts, applicable downspout-disconnection conditions and the specific work proposed. If a condition is unclear, resolve it with the city before relying on the subsidy in your budget. Keep this municipal review separate from the contractor’s technical recommendation. Neither a sales estimate nor a general promise to handle rebates replaces the homeowner’s understanding of the property conditions.
Keep permits, inspection and concealment in the correct order
For a backwater valve, Toronto’s instructions require a building permit and an inspection after installation. The valve must not be covered before inspection. Ask the contractor to put the permit and inspection responsibility in the written scope and explain where access will remain. A finished floor should not make a required inspection or later maintenance impractical.
For a sump pump and backup, request separately itemized component costs and the photographs required by the city. Ask where the discharge goes and how the system will be maintained. Compare like-for-like proposals with our quote comparison guide, including excavation, restoration, electrical work, alarms and access. A lower price may describe a different installation rather than a cheaper version of the same job.
Budget from your eligible invoice, not the combined ceiling
Build a line-by-line calculation using only the components actually proposed. Show the invoiced cost, the applicable percentage, the component cap and any previous property usage. Keep costs that are not eligible in a separate column. This avoids treating an unused allowance for one measure as money that can automatically be shifted to another.
Before submission, reconcile the paid invoices, contractor details, permit or inspection records, assessment form and photographs with the city’s current application checklist. At handover, ask for a demonstration of the alarms and any backup equipment, together with maintenance instructions. Retain the completed file with the home’s records so that a future owner or a later repair contractor can identify the installation. Flood-risk reduction is an ongoing maintenance responsibility even after the subsidy file is closed.

Make future maintenance practical
Before restoring floors or wall finishes, ask the installer to identify the access points that must remain usable. Photograph their locations and keep the equipment instructions with those photographs. Add alarm checks, battery information and the installer’s maintenance advice to the home’s routine checklist. These records are useful even when no further subsidy is available, because later repairs should not make the protective equipment inaccessible.
