Help protect yourself against basement flooding
Basements can flood for many reasons. While the City of Toronto is working to make improvements to its complex system of underground pipes, sewers and catchbasins, these improvements alone cannot completely protect a home from basement flooding. With the increasingly frequent and severe weather, it is essential that homeowners take the appropriate action to reduce the risk of basement flooding on their own private property.
Those who isolate their home from the City’s sewer system can significantly reduce the risk of basement flooding.
Apply for Subsidy ProgramFill application form
To assist, the City offers owners of single-family, duplex and triplex residential homes a financial subsidy of up to $3,400 per property to install flood protection devices including a backwater valve, a sump pump, and pipe severance and capping of the home’s storm sewer or external weeping tile connection.
The following items and works are eligible for a subsidy after proper installation:
- Each property owner is required to have a contractor licensed by the City of Toronto carry out a site assessment to determine the suitability of isolating their property from the City’s sewer system.
- Contractors with a valid City of Toronto business license will have a 9 digit license number beginning with the following: T94, T92, T87, T85.
- Before work starts, verify that your contractor has a valid City of Toronto business license by contacting Municipal Licensing & Standards (MLS) at 416-392-6700 or checking online. If your contractor does not have a valid City of Toronto license, you will be denied funding for the work completed.
A: Backwater valve
In consultation with a City of Toronto Plumbing Contractor (T94, T92) or Drain Contractor (T87), homeowners may determine that a backwater valve(s) on the sanitary sewer and/or stormwater connection could provide adequate basement flooding protection.
Available subsidy = 80% of the invoiced cost up to a maximum of $1,250 including eligible labour, materials, permit and taxes. The subsidy for a backwater valve(s) is limited to the maximum subsidy amount of $1250, regardless of the number of valves installed at the property.
The following costs associated with the backwater valve installation also qualify for the subsidy.
- Replacement of an existing backwater valve
- Installation of an alarm
B: Sump pump
In consultation with a City of Toronto Plumbing Contractor (T94, T92) and/or a Building Renovator (T85), homeowners may determine that a sump pump, along with a backup power supply is required to manage the water normally collected by footing weeping tiles that drain to the sanitary, storm or combined sewer. Seek advice from your contractor to see if installing a back-up power source would benefit your property.
Available subsidy = 80% of the invoiced cost up to a maximum of $1,750 including eligible labour, materials and taxes.
The following costs associated with the sump pump installation also qualify for the subsidy.
- Installation of an alarm for a sump pump
- Installation of back-up power for a sump pump
- Installation of an additional sump pump
- Replacement of an existing sump pump
C: Foundation Drain (Weeping Tile) pipe severance and capping
In consultation with a City of Toronto Plumbing Contractor (T94, T92) or Drain Contractor (T87) homeowners may determine that disconnecting foundation drains (weeping tiles) from the City’s sewer system by severing and capping the underground sewer connection is also required to protect the home from basement flooding.
Available subsidy = 80% of the invoiced cost up to a maximum of $400 including eligible labour, materials and taxes.
Note: Disconnecting the downspouts from your property’s eavestrough system is not eligible for a subsidy under this program.
The City of Toronto will determine the eligibility of properties that meet the requirements listed below:
- The property must be registered as a single-family residential, duplex or triplex property within the City of Toronto.
- The subsidy is only available to existing homes that were constructed prior to January 1, 2009.

- A permit must be obtained and inspection passed by a City of Toronto building inspector for a backwater valve.
- Your contractor must possess a valid City of Toronto business license.
- Original invoices must be provided.
- Submitting an application does not guarantee a subsidy. Subsidies are issued on a “first-come, first-served” basis, and are subject to annual funding approved by City Council.
- The property must not have exceeded the combined lifetime maximum subsidy amount of $3,400 for each eligible installation.
- Subsidies for eligible work are subject to available funding and provided on a first-come, first-served basis.
- Subsidies are provided one time only for each eligible installation, per property, and on a no-fault basis.
