Introduction
Sump pump installation in Toronto starts from $720 for a new system with pit and pump, or from $360 if you are replacing an existing pump in a working pit. Battery backup systems add $1,080 to $2,800. The City of Toronto rebate covers up to $1,750 (80% of the invoiced cost) for sump pump installations. This guide covers the real costs, what is included, and how to maximize the city rebate.
What affects sump pump installation cost in Toronto
Pump type: submersible pumps ($500 to $1,200 installed) are the most common and sit inside the pit. Pedestal pumps ($400 to $700 installed) are less expensive but noisier. Battery backup systems add significant cost but provide protection during power outages — which in Toronto often coincide with the heavy storms that cause flooding. New pit vs existing pit: if your home already has a sump pit, replacing the pump is straightforward ($360 to $900). A new installation requires cutting the basement floor, digging the pit, installing the basin, and running the discharge line — this is where costs reach $720 to $2,200. Discharge line routing: the discharge pipe must carry water at least 1.5 metres from the foundation. Longer runs, routing through walls, or connecting to a storm sewer add cost. Soil conditions: much of Toronto sits on clay soil that drains poorly. This can require a more robust drainage system around the sump and a higher-capacity pump. Season: spring (March through May) is peak demand for sump pump work in Toronto. Fall installations before winter often get better scheduling and may cost less due to lower demand.
City of Toronto sump pump rebate
The City of Toronto reimburses 80% of the invoiced cost of sump pump installation, up to a maximum of $1,750. This includes the pump, pit, discharge line, battery backup, labour, permit, and taxes. For example, if a new sump pump installation costs $1,800 total, the city reimburses 80% = $1,440. Your net cost: $360. If you also install a backwater valve, you can apply for an additional rebate of up to $1,250 for the valve, bringing the combined maximum to $3,400 per property. We handle the permit application and inspection scheduling. For the full rebate process, see our Toronto Basement Flooding Rebate Guide.
Is a battery backup sump pump worth it?
In Toronto, power outages and heavy storms often happen at the same time. A primary sump pump without backup is useless during a power outage — which is exactly when you need it most. A battery backup sump pump activates automatically when the primary pump loses power or fails. The cost is $1,080 to $2,800 depending on the battery capacity and pump rating. Runtime on battery power is typically 4 to 12 hours depending on how frequently the pump cycles. The battery backup cost is included in the City of Toronto sump pump subsidy (up to $1,750 covers the primary pump, backup, and installation combined). For most Toronto homeowners with basements, the backup is the difference between a protected home and a flooded one during a summer storm.

Sump pump cost FAQs
How much does it cost to replace a sump pump in Toronto?
If the existing pit and discharge line are in good condition, a pump replacement typically costs $360 to $900. If the pit needs to be enlarged or the discharge rerouted, costs can reach $1,200 or more.
How long does a sump pump last?
Submersible sump pumps typically last 7 to 10 years. Pedestal pumps can last 25 to 30 years because the motor stays above water. Proactive replacement before failure costs $360 to $900. Emergency replacement after a basement flood costs the same for the pump — plus $5,000 to $50,000 in water damage.
Do I need a permit for sump pump installation in Toronto?
Simple pump replacements in an existing pit typically do not require a permit. New installations that involve plumbing modifications or connection to the municipal storm sewer do require a permit. We determine permit requirements during the estimate and handle applications when needed.
Can I combine a sump pump and backwater valve to maximize the rebate?
Yes. The City of Toronto allows you to apply for both the sump pump subsidy (up to $1,750) and the backwater valve subsidy (up to $1,250) on the same property, for a combined maximum of $3,400. Combining both installations in one project also reduces per-job cost.
