Apply to Get up to 80% of Your Money Back on Basement Flooding Protection

Basement Flooding Protection Subsidy Program 2017

With the increase of flash weather events like heavy rainstorms and snow melts the thought of your basement filling up with Toronto sewer water may leave you feeling noxious. Fortunately, the City of Toronto has created an opportunity for property owners to prevent sewer water backup and to benefit by a program that offers up to $3,400.00 in financial subsidies on their residences.

The initiative is called The Basement Flooding Protection Subsidy Program and is available to residential single-family, duplex and triplex homes in Toronto.

The subsidy is available to those who install flood protection devices such as a backwater valve, a sump pump, and foundation drain pipe severance and capping of the home’s storm sewer or external weeping tile connection.

Peter Goffin, Staff Reporter for the Toronto Star wrote about the City of Toronto’s subsidy in May of 2017.

“Over the past decade, the municipal government has put $37 million toward the costs of flood-proofing for 21,500 properties, through the Basement Flooding Protection Subsidy Program.”


The average homeowner participating in the program has received up to $1,700.00 in subsidies. In order to participate, homeowners must obtain building permits and have their licenced contractors complete the work and pass city inspections in advance of submitting their application for subsidies to City Hall. The approval process can take several weeks. The demand for application submission may exceed the money available in the City’s allocated annual budget for flood prevention and the distribution of funds is based on a first come, first serve basis.

Demand for flood protection has increased over Southern Ontario. In the great rainstorm of 2013 when Toronto was deluged with a month’s worth of rain in a week, the equivalent to 12.6 m of rain according to Environment Canada weather reports, fell and drowned out highways, subway stations, roads, and backyards as well as basements. From that flood alone the city received over 4,700 complaints of flooding.


The following is a breakdown of the three types of flood protection work that is eligible for this financial subsidy:


A:  BACKWATER VALVE Installation Cost Subsidy
