Basement Flooding Protection Subsidy Program
Basement flooding and intense rainfall are becoming more common throughout Scarborough. To help protect homes from costly water damage, the City of Toronto offers a subsidy program to offset the cost of flood prevention systems and services.
The City’s Basement Flooding Protection Subsidy Program offers up to $3,400 to eligible owners of single-family, duplex, triplex, or fourplex homes. Mersey Heating and Air Conditioning is proud to provide the professional installations and upgrades that are included under this program.


What Is the Basement Flooding Protection Subsidy Program?
This program helps Scarborough homeowners protect their properties from flooding. While the city continues to improve infrastructure at a community level, individual properties still face significant flood risk. The subsidy allows homeowners to take action through approved flood prevention measures.
Mersey Heating and Air Conditioning is fully certified to install all equipment covered by the Basement Flooding Protection Subsidy Program. We’ll walk you through the process from inspection to application.
What Does the City of Toronto Basement Flooding Protection Subsidy Cover?
The following services and devices are eligible under the subsidy:
Backwater (Backflow) Valve Installation
Prevents sewage backups from entering your basement. Whether you’ve experienced a backup before or not, installing this device can make all the difference during major rainstorms.
Sump Pump Installation
Removes excess groundwater from your basement and helps keep it dry and free from mould. If you’re unsure whether your home needs one, our technicians can evaluate and advise.
Severance and Capping of Storm Sewer or External Weeping Tile Connection
This involves disconnecting your foundation drains from the city sewer system, helping prevent water from overwhelming your basement during heavy rains.
Additional waterproofing or drainage improvements may also qualify. If you’re not sure what’s needed, Mersey can provide a full consultation and help determine your eligibility for funding.
