Basement Flooding Subsidy in Ontario: Every City Program (2026)
Searching for an "Ontario basement flooding subsidy" leads to a surprise: there is no provincial program. The money is municipal — each city decides whether to pay homeowners for flood-protection work like backwater valves and sump pumps, and how much. This page is the map: every major program, one table, kept in sync with our city guides.
The short version
Toronto pays the most — up to $6,650 per property through the Basement Flooding Protection Subsidy Program (BFPSP), covering 80% of eligible work. Most GTA municipalities run their own smaller programs. Your address decides everything.

What these programs typically pay for
The two workhorses are the backwater valve (blocks sewage from backing up into your basement during storms) and the sump pump (pumps groundwater out before it rises). In Toronto, for example, the subsidy covers up to $3,200 for backwater valves and $2,550 for a sump pump with battery backup — other cities define their own lists.

Is there a provincial basement flooding subsidy in Ontario?
No. Basement flood-protection subsidies in Ontario are municipal — each city runs (or doesn’t run) its own program with its own amounts and eligible work. Toronto’s BFPSP is the largest at up to $6,650 per property.
My city isn’t in the table — do I have options?
Some municipalities have no program, and a few run small or intermittent ones. Check your city’s website for “basement flooding” or “sewer backup subsidy,” or start from our calculator — the city selector covers the major programs and an “other” path.
Is this the same as insurance?
No — subsidies pay toward prevention work (backwater valves, sump pumps) before flooding; insurance responds to damage after. Many insurers also view installed prevention devices favourably, but terms vary by policy, so confirm with your provider.
