Toronto Basement Flooding Subsidy 2026 | Up to $6,650 Back

Need help with the Toronto Basement Flooding Subsidy? As of May 1, 2026, the City of Toronto has nearly doubled its support for homeowners. The maximum subsidy per property has jumped from $3,400 to $6,650—providing significantly more financial help for backwater valves, sump pumps, and battery backups.

What Qualifies for the Toronto Basement Flooding Subsidy?

The City reimburses 80% of the total invoiced cost for eligible work. Here is the breakdown of what you can claim through Top One Plumbing:

1. Backwater Valve Installation (Up to $1,600)

This includes the valve, labor, and materials. A plumbing permit is required for this work—Top One Plumbing handles the permit and inspection process for you to ensure your application isn’t rejected.

2. Sump Pump Installation (Up to $2,250 + $300)

Covers the pump, pit, and discharge piping. You can now get an additional $300 specifically for a battery backup system, ensuring your basement stays dry even during power outages.

3. Home Plumbing Assessment (Up to $500 – NEW for 2026)

Homeowners can now receive up to 80% of the cost for a professional licensed plumber in Toronto to assess internal plumbing and identify flood risks.

• North York & East York: Areas often served by combined sewer systems.
• Etobicoke (Mimico, Long Branch): Lakeside communities with shallow foundations.
