Exterior drains tied to private drainage
Tying into your existing private storm line, sump discharge, or a dry well has its permit scope determined by the City under its by-laws. We confirm what applies before work begins.

Trench Drain Installation in Etobicoke
Drainage across Etobicoke — from the mature Kingsway streets to the low-lying lakeshore where the water table sets the design.
What we install
Trench drain work across Etobicoke
Etobicoke covers two very different drainage problems. Inland, mature trees and older private lines dominate. Along the lakeshore in Mimico, Long Branch, and Humber Bay, a high water table means the outlet often has to be pumped rather than gravity-fed.
Install Process
How a trench drain goes in
Six on-site steps from the first cut to a flush, water-tight finish. Same sequence on every job — what changes is length, materials, and crew size.
-
01
Plan & Mark
- Identify water flow direction
- Mark full drain run across the opening
- Confirm outlet location and slope (~1%)
-
02
Excavate Trench
- Cut and remove concrete or asphalt
- Trench wider and deeper than the channel
- Maintain consistent slope toward the outlet
-
03
Prepare Base
- Add compacted gravel or concrete base
- Set elevation using string line or laser
- Base supports full channel length
-
04
Install Channel
- Place channel sections across full trench
- Connect end-to-end with no gaps
- Align slope and elevation across the run
-
05
Concrete & Backfill
- Pour concrete around both sides of channel
- Maintain proper thickness and support
- Finish surface flush with surrounding slab
-
06
Grate & Finish
- Secure the grate into the channel
- Ensure flush finish with the slab
- Final check: water flows cleanly into drain
Customer review
What Etobicoke homeowners say
Water table is a metre down here. They said a deep line was impossible and designed a shallow run with a pump instead. It works.
Etobicoke-specific
Toronto Water, the flood subsidy, and three regulated watercourses
Etobicoke is part of the City of Toronto, so Toronto Water rules and the Basement Flooding Protection Subsidy apply. Etobicoke Creek, Mimico Creek, and the Humber River all cut through, which brings TRCA into a large share of local jobs.
Basement Flooding Protection Subsidy
Eligible Etobicoke properties access the same City of Toronto program as the rest of the city, covering backwater valves, sump pumps, and downspout disconnection. Trench drainage inside a wider eligible scope can sometimes form part of a claim.
Etobicoke Creek, Mimico Creek, and the Humber
Etobicoke Creek in particular has mapped flood plain through built-up residential areas. Properties inside a regulated area need TRCA review of excavation and drainage changes before the City acts.
Sanitary sewer tie-ins
Municipal sewer use by-laws govern what may enter the sanitary sewer, and surface water is restricted under them. On the older lakeshore infrastructure this is precisely how sewage backs into a basement during a storm. We do not install it.
Coverage
Response from our Richmond Hill base
Etobicoke is 40 to 60 minutes from Richmond Hill depending on the 401 and the 427, and it is part of our standing Toronto rotation rather than an occasional run.
Site visits are booked in fixed windows. The crew that quotes the job installs it. Most residential installs are one day on site, then 24 to 48 hours of cure before vehicles cross the patch.

FAQ
Common questions about trench drains in Etobicoke
Do I need a permit for a trench drain in Etobicoke?
Usually not for the drain itself when we tie into existing private drainage. A new municipal storm connection requires a Toronto Water permit, and TRCA review applies if the property sits inside a regulated area near Etobicoke Creek, Mimico Creek, or the Humber. Both are confirmed on the site visit.
I am in Mimico and everything stays wet. Is a deeper drain the answer?
Almost certainly not, and this is the most common mistake made on lakeshore Etobicoke lots. When the water table sits close to the surface, digging deeper just finds groundwater and the channel never empties. The fix is a shallower run with properly built fall, discharging to a pumped outlet. We measure the water table before designing anything.
Does the Toronto flood subsidy apply in Etobicoke?
Yes. Etobicoke is part of the City of Toronto and eligible properties access the same Basement Flooding Protection Subsidy. It covers backwater valves, sump pumps, and downspout disconnection rather than a trench drain by itself, though trench drainage inside a broader eligible scope can sometimes be included.
My property is near Etobicoke Creek. Does that complicate things?
It adds a review step. Etobicoke Creek has mapped flood plain running through established residential streets, and TRCA regulates excavation and drainage changes inside it. That is weeks of approval rather than days, so we identify it at the site visit and build it into the timeline honestly.
What does an Etobicoke trench drain cost?
Residential installs fall in the $1,800 to $4,500 GTA range. Lakeshore jobs move toward the upper end when a pumped outlet is required, because a pump, a basin, and a discharge line are real additional work beyond the channel itself.
The Kingsway has huge trees along the driveways. Can you work around them?
Usually yes. Toronto protects trees over a set size and the root zone matters as much as the trunk. We hand-excavate near roots and route the channel to avoid the critical zone where we can. If the only viable line runs straight through protected roots, we tell you before you commit.
Do you handle Etobicoke commercial properties?
Yes — plaza aprons, loading areas, service bays, and industrial floors across the Queensway and north Etobicoke employment lands. All quoted after a site visit.
How long is my driveway out of action?
One day for the install on most residential jobs, then 24 to 48 hours before vehicles cross the patch. We agree where you will park before we start rather than raising it when the concrete is already cut.
