Toronto Sump Pump Subsidy
Some Toronto homeowners may be eligible for the Basement Flooding Protection Subsidy Program.
For eligible sump pump work completed on or after November 12, 2025, the City may cover up to 80% of the invoiced cost, up to $2,250, for one sump pump installation or replacement.
If backup power is installed for the sump pump, a separate subsidy of up to 80% of the invoiced cost, up to $300, may also apply. If a sump pump and battery backup are installed together, the invoice should itemize each component separately.
Cheap Plumber can assess your sump pump setup, complete eligible installation or replacement work, and provide documentation needed for the subsidy application.
Full Program Note
The expanded Toronto program may provide up to $6,650 total per eligible property for approved basement flood protection work, including home plumbing assessments, backwater valves, sump pumps, sump pump backup power, and foundation drain or weeping tile severance and capping.
This subsidy applies to eligible properties within the City of Toronto. Cheap Plumber provides sump pump services in Toronto and nearby areas, but Toronto subsidy eligibility depends on the City’s program requirements.
