Quick answer
Up to $2,250 for sump pump + $300 for battery backup = $2,550. Subsidy covers 80% of cost.
What a sump pump does
A sump pump moves groundwater collected by your weeping tile system away from your foundation before it can enter the basement. Toronto's largely clay soils and aging building stock — commonly cited flood-risk factors — make basement flooding a real risk, especially during severe storms.
The City recommends discharging onto a permeable surface at least 2 metres from the foundation.

Why the battery matters
The same severe storms that cause flooding also cause power outages. Without battery backup, your sump pump stops working at the exact moment you need it most.
Adding the $300 battery backup to a $2,250 sump pump subsidy is one of the highest-value combinations in the program — typical battery installation costs $300–$500 (installation cost, not a program cap), so the subsidy covers most or all.
Stacking with backwater valve
Sump pumps and backwater valves protect against different types of flooding:
- •Sump pump: handles groundwater coming up from below
- •Backwater valve: handles sewage backup from the City sewer
Most flood-prone Toronto homes need both. Combining sump pump $2,250 + battery $300 + 2 backwater valves $3,200 + plumbing assessment $500 + foundation drain capping $400 reaches the program max of $6,650.

How much is the Toronto sump pump subsidy?
Up to $2,250 for the sump pump + up to $300 for battery backup = $2,550 combined. The subsidy covers 80% of the invoiced cost.
Do I need a battery backup?
Strongly recommended. Power outages often happen during the same severe storms that cause flooding. Without battery backup, your sump pump won't run when you need it most. The City offers a separate $300 subsidy specifically for battery backups, including retrofits to existing sump pumps.
Can I install a sump pump alongside a backwater valve?
Yes — many homeowners do, since they protect against different failure modes. If installed together, you need a Consent to Enter form with the permit application so both can be inspected.
Outside Toronto?
Most GTA municipalities run their own basement flooding subsidy programs — amounts and eligible work differ city by city. See Mississauga, Markham, Hamilton — see the full Ontario program map or start from the city selector in the calculator.
