Sump Pump Installation Toronto installs sump pumps, battery backups and sump + backwater valve combos across Etobicoke, from Mimico, New Toronto and Long Branch on the lake to Islington, The Kingsway and Rexdale. Lakefront and creek-side homes here can see a high water table after long rain events, so we size the pit and pump to real inflow and plan a discharge route that keeps working in winter. A licensed Master Plumber pulls the permit, installs to Ontario Plumbing Code Part 7 and files the City of Toronto subsidy for eligible addresses.

The Local Problem
What you see: Water seeps along the back wall after a long rain, and the old pit fills faster than the pump can empty it.
Why it happens here: Homes near Mimico Creek and Etobicoke Creek sit on low ground beside a lake that set a record 76.03 m in 2019, so groundwater has nowhere to go.
What we do: We flow-test the pit, fit a deeper sealed basin with a properly sized pump and add a backwater valve where the floor drain has backed up.
The float sticks or the motor burns out halfway through a long storm, and water starts rising in a finished basement.
Storms that flood basements often take the power too, and a pump with no electricity is no help.
No permit, no inspection, a lump-sum invoice: the reasons City subsidy claims and insurer renewals stall.
Homes near the lake and along the Humber River and Mimico Creek see high groundwater after long rains, so pit depth, pump capacity and a dependable discharge route matter more than usual.
$5,500 - $9,500
Full $1,750 Max City Subsidy Applied
Backwater valve at the building drain plus a sealed sump and weeping tile redirect: both flood paths covered, full $1,750 subsidy.
$1,800 - $3,200
Eligible for $500 City of Toronto Rebate
New sump pit cut into your basement slab, sealed basin, cast iron pump and freeze-proof discharge, usually done in one day.
$900 - $5,100
Subsidy eligibility confirmed at assessment when part of a new sump install
Secondary 12V pump on a deep-cycle battery with its own float and WiFi alarm, so the pit keeps draining when the power goes out.
Every job here is run by the same licensed crew behind our Toronto sump pump installation service, with the same published pricing and City subsidy filing. Also available: weeping tile disconnection, replacement, 24/7 emergency repair, submersible upgrades, perimeter drains, insurance claim installs and City rebate filing.
We use our city-wide published ranges here. A new interior sump pump installation runs $1,800 to $3,200 CAD, with most Toronto jobs landing at $2,400 to $2,800 before the subsidy. Homes with a high water table near the lake or creeks are more likely to need a 24 gallon basin or a 1/2 HP high-flow pump, which sits toward the upper end.
A battery backup adds $900 to $2,200 to an existing pit, and a sump + backwater valve combo runs $5,500 to $9,500. On eligible Toronto addresses, the City subsidy can return up to $500 on a sump or $1,750 on a combo. We file it at no charge.

"Our insurer wouldn't renew until we had a sump installed after the backup. One PDF with permit, CSA B64.10 backflow cert, flow test and photos went straight to the adjuster. Renewed in days."
"After the July 2024 storm backed up our Rosedale basement, we went full combo: Mainline backwater valve, Zoeller M63 and Aquanot battery. Full $1,750 subsidy cheque arrived about seven weeks later."
"Cliffside bungalow with weeping tile into the sanitary line. They capped it, redirected to a sealed sump and added the backwater valve. Inspector signed off the same week."
Etobicoke has a long flood history. In 1954 Hurricane Hazel sent Etobicoke Creek through Long Branch and swept homes into the lake; Marie Curtis Park now sits where they stood. The creeks still rise fast, and the Humber River and Mimico Creek do the same after long rains.
The lakeshore is the other pressure point. Lake Ontario hit a record 76.03 m in 2019, and in the first half of 2015 the Etobicoke-Lakeshore ward logged more basement flooding reports than any other ward in the city. The City's flooding study for the Lake Shore Boulevard and Mimico Creek area now calls for a new 1500 mm storm sewer.
For homes in Mimico, New Toronto and Long Branch, that means a pit deep enough to catch water below the slab, a pump sized from a flow test and a discharge that keeps working in February.
What We Account For Here
This side of the city is shaped by water. The Humber River runs along its eastern edge, Mimico Creek and Etobicoke Creek cut through it, and the south end sits on the lake. After long rain events, like the July 16, 2024 storm that dropped 97.8 mm at Pearson, right next door, groundwater rises and pits fill fast.
That makes three things more important than usual: pit depth, so water is caught below the slab; pump capacity, sized from a flow test rather than a guess; and a dependable discharge route with proper slope and a freeze-resistant outlet, so the line does not ice up in February.
Lakefront homes in Mimico, New Toronto and Long Branch. Close to the Lake Ontario shoreline, groundwater can sit high after long rains. These basements need pits deep enough to catch water before it reaches the slab, and pumps sized to keep up.
Creek-side homes. Streets near the Humber River, Mimico Creek and Etobicoke Creek see higher groundwater during spring thaw and big storms. A battery backup matters here, because the pit may run hard on exactly the nights the power goes out.
The Kingsway and Islington. Older, larger homes, often with finished basements and long discharge runs. We plan the discharge around landscaping and walkways so it drains away from the house without icing over a path.
Rexdale. A mix of bungalows and semis, including homes recovering from sewer backup claims that now need an insurer-ready install and paperwork.
Local Landmarks
Getting There
Crews use the Gardiner, the QEW and Highway 427, booking lakeshore visits together and Rexdale and Islington visits together.
Routes: Gardiner Expressway, Queen Elizabeth Way, Highway 427, Highway 27
Transit: Kipling station, Islington station, Mimico GO, Long Branch GO
Etobicoke runs from Lake Shore Boulevard West up through Islington and Kipling to Rexdale near Highway 27. We schedule lakeshore visits (Mimico, New Toronto, Long Branch) together and north-end visits (Rexdale, Islington) together, using the Gardiner, QEW and Highway 427 to move between them. Non-emergency assessments are usually booked within 2 business days, with 24/7 live answer for emergencies.
Lakefront streets can be tight for parking, especially in summer. We confirm parking and access at the assessment so install day runs on time. Drain permits are filed with Toronto Building, usually about 5 business days ahead, and inspections are normally completed the same week.

Thanks, we got your request.
A member of the Sump Pump Toronto Crew will call you back, usually the same business day. Water rising right now? Call (437) 782-5911.
Not always bigger, but sized correctly. Homes near the lake and creeks often see faster inflow after long rains. We flow-test the pit and may recommend a 24 gallon basin or a 1/2 HP pump if the numbers call for it.
In the first half of 2015, Ward 6 Etobicoke-Lakeshore logged 215 basement flooding reports, the most in Toronto. Low lakeshore ground, three creeks and older sewers all play a part.
Basement Flooding Study Area 53 recommends a new 1500 mm storm sewer along Lake Shore Boulevard West near Mimico Creek. Until it is built, a sealed sump and backwater valve protect the house itself.
Published ranges apply: $1,800-$3,200 CAD for a new interior install. Deep pits and high-flow pumps for lakeshore water tables sit toward the upper end.
We recommend it. Creek-side pits can run hard during storms, and those storms often take out the power at the same time.
We give the line enough slope to drain fully between cycles and finish with a freeze-resistant outlet aimed away from the house and walkways.
Yes. We install to Ontario Plumbing Code Part 7 and deliver one adjuster-ready PDF with the invoice, permit, CSA B64.10 certificate, flow test and photos.
If the floor drain has ever backed up during a storm, it is worth discussing. A sump plus backwater valve combo runs $5,500-$9,500 CAD and can qualify for a larger City subsidy.
Yes. Rexdale, Islington and The Kingsway visits are grouped along Highway 427, so assessments are usually booked within 2 business days. Live answer is available 24/7 for emergencies.
Yes. The City of Toronto subsidy does not apply there, since Mississauga runs its own programs.
Honestly, that is the whole pitch. We would rather spend an hour at your house now than pump out a finished basement later.
