The sump pump installation cost in Ontario is typically $800 to $3,000 for a pump with a new pit, and $1,500 to $4,500 once you add a battery backup. Replacing a pump in an existing pit costs less than building a new pit. These are typical ranges, not quotes. Your price depends on pit work, concrete cutting, pump size, discharge routing and electrical work.
Typical sump pump installation costs in Ontario
The figures below come from published contractor estimates for the Toronto area. Most are marketing pages, so treat them as rough guides. Prices in Vaughan and Brampton are usually close to the Toronto range, but no public source sets a fixed price. Always get written quotes.
| Job | Typical range (CAD) | Main cost drivers |
|---|---|---|
| New pit and primary pump | $800 to $3,000 | Cutting the slab, digging, pit liner, pump grade, discharge pipe |
| Replace pump in an existing pit | Usually below the new pit figure | Pump quality, check valve, pipe condition |
| Battery backup add-on | $300 to $1,500 | Battery size, charger, separate backup pump or combined unit |
| Primary pump plus battery backup | $1,500 to $4,500 | All of the above, plus electrical work |
| Water alarm or monitoring | Varies | Local alarm or phone alert |
Where we say a price “varies”, we found no solid public basis for a number. Ask each contractor to itemize.
What pushes the price up
- Concrete work. Cutting a slab, digging a pit and patching the floor take most of the labour in a new installation.
- Pump type. A submersible pump usually costs more than a pedestal pump. It also runs quieter and handles heavy use better.
- Discharge distance. A long run to the yard or a storm connection adds pipe, trenching and time.
- Electrical work. A battery backup needs a plug in the right place. Any new circuit must be done by a licensed electrician.
- Finished basements. Flooring and drywall around the pit make access harder and raise the price.
- Water source. If the pit is not connected to a weeping tile system, the pump may do little. Fixing the drain costs more than the pump.
New pit or replacement?
Choose the job from what you have today.
| Your situation | Likely job | Cost direction |
|---|---|---|
| A working pit, a failed or old pump | Replace the pump only | Lowest |
| A pit that is too small, cracked or silted | Replace the pit liner and pump | Middle |
| No pit, but a wet basement | Break the slab and add a new pit | Higher |
| No pit, no weeping tile or a blocked tile | Drain repair plus a new pit | Highest |
A sump pump moves water that already reached the pit. It does not stop water entering the foundation. If your basement floods in spring melt or heavy rain, ask whether the weeping tile around the footing is clear. A camera inspection helps. A pump on a blocked drain is a short-term fix.
Replacement checks
Most pumps in homes last about 7 to 10 years under regular use. Ask the installer to check these items before they replace only the pump:
- Is the pit deep and wide enough for a float to move freely?
- Is there a working check valve on the discharge line?
- Does the pit have a lid, so debris and radon-bearing soil gas stay out?
- Does the outlet circuit have ground fault protection?
Battery backup: when the extra cost makes sense
Power cuts often happen during the same storms that raise the water table. A pump without power does nothing. A battery backup runs a second pump from a deep-cycle battery for several hours. The length depends on how often the pump runs.
A backup makes the most sense in these cases:
- Your basement is finished, or holds stored goods or a furnace.
- Your area has a history of storm outages.
- You are away for long periods, such as winter at a cottage.
- Your insurer asks for it. Check your policy for water damage and sewer backup cover.
Two designs are common. One adds a small backup pump in the same pit. The other uses a larger unit with a sealed battery and a built-in controller. The second type costs more but often pumps longer. Ask the installer how many hours of pumping the system gives, and how often the battery needs replacing. A battery typically needs a check every year.
Discharge rules: where the water may go
Discharge is the part of the job that most often causes a failed inspection or a complaint from a neighbour. Rules differ by municipality, so read your own city by-law before the work starts.
- No sanitary sewer connection. Many Ontario municipalities state that a sump connection to the sanitary sewer breaks the Ontario Building Code and their sewer use by-law. Sewage can back up into basements when storm flows overload the system.
- Away from the foundation. The City of Toronto asks that the pump empties onto a permeable surface at least two metres from the foundation wall. Read the City of Toronto subsidy page for the full wording.
- Not onto a neighbour’s lot. Water that runs across a property line causes disputes. It can also freeze on a shared path in winter.
- Downspouts. Toronto states that disconnecting downspouts from the sewer system is mandatory. Disconnected downspouts also reduce the load on your pump.
- Winter. In Ontario, discharge pipes can freeze. Ask for a pipe that slopes away from the house and ends in an open spot. An outlet that freezes shut sends water back to the pit.
Vaughan and Brampton have their own by-laws. This guide does not quote them. Call the city or read the sewer use by-law on the city website before you choose a discharge point.
Toronto subsidy for sump pumps
Toronto lists a subsidy for eligible flood protection work. The details below come from the City of Toronto page as read on 2 November 2026:
- Sump pump: 80 per cent of the invoiced cost, up to $2,250, one device, for installation or replacement plus an alarm.
- Battery backup: an additional 80 per cent of the invoiced cost, up to $300.
- Dates: the expanded amounts apply to work completed on or after November 12, 2025. Applications opened from May 1, 2026.
- Invoice: if you install a pump and a battery backup, the contractor must list each part as a separate line.
- Photos: applications need photos of the pump and discharge pipe outside the home.
Eligibility rules apply, so read the page before you sign a contract. Vaughan and Brampton are not covered by the City of Toronto programme. Ask your own city or region whether a similar programme exists.
What our boards show for Toronto, Vaughan and Brampton
Our boards rank companies by Google rating and review count. They show data, not endorsements. Sump pump work is usually done by waterproofing contractors and plumbers, so the waterproofing boards are the closest match. Figures are from the 2026-10 data.
| Town | Companies ranked | Total reviews | Median reviews | Companies under 20 reviews |
|---|---|---|---|---|
| Toronto | 20 | 3,934 | 81.5 | 1 |
| Vaughan | 20 | 2,688 | 69.0 | 3 |
| Brampton | 19 | 1,806 | 38 | 6 |
The median rating is 5.0 on all three boards. That means a rating alone does not separate companies. Review count does more work. In Toronto, the middle company has 81.5 reviews, and only one of 20 has fewer than 20. In Brampton, the middle company has 38 reviews, and 6 of 19 have fewer than 20. A thin review base is harder to judge.

How to compare quotes
Ask each contractor for a written, itemized quote. Compare these points, not only the total:
- Scope. Does the price include the pit, pump, check valve, lid, discharge pipe and slab patch?
- Pump model and warranty. Ask for the model name and the length of the warranty on parts and labour.
- Backup details. Ask for the battery size and the hours of pumping time.
- Discharge plan. Ask where the water will go and how the contractor will keep the line from freezing.
- Electrical. Ask who does the electrical work and whether it is licensed.
- Subsidy paperwork. In Toronto, ask for separate invoice lines for the pump and the battery backup.
- Drain check. Ask if the contractor inspected the weeping tile, or why not.
A low quote that leaves out the slab patch or the discharge pipe is not low. Ask every bidder to price the same scope.
Frequently asked questions
How much does a sump pump installation cost in Ontario?
Published Toronto-area contractor estimates run from about $800 to $3,000 for a primary pump, depending on whether a new pit is needed. A pump with a battery backup typically lands between $1,500 and $4,500. These are typical ranges, not quotes.
Is a battery backup sump pump worth the extra cost?
A battery backup keeps the pit pumping when a storm cuts the power, which is when most basements flood. Published add-on estimates run from about $300 to $1,500. Toronto also lists a separate subsidy for battery backups.
Where must a sump pump discharge in Ontario?
Rules differ by municipality, but Ontario towns generally do not allow a sump pump to connect to the sanitary sewer. Toronto asks for discharge onto a permeable surface at least two metres from the foundation. Check your own city by-law first.
Can I get money back for a sump pump in Toronto?
Yes, for eligible homes. The City of Toronto page lists 80 per cent of the invoiced cost, up to $2,250, for a sump pump installed on or after November 12, 2025. A battery backup adds up to $300 more.
