Private drainage tie-in
Tying into your existing private storm line, sump discharge, or a soakaway on your own lot has its permit scope determined by the Town under its by-laws. We confirm what applies before work begins.

Trench Drain Installation in East Gwillimbury
Trench drains across East Gwillimbury — one of the fastest-growing parts of York Region, and one of the most closely watched watersheds.
What we install
Trench drain work across East Gwillimbury
East Gwillimbury pairs rapid new-subdivision growth in Queensville and Sharon with older hamlets and rural properties. Which one you are on decides whether the outlet is modern infrastructure or something we build.
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 East Gwillimbury homeowners say
New build, and the grading never worked from day one. They told us to call the builder first. We did, and it got fixed on warranty.
East Gwillimbury-specific
Lake Simcoe watershed rules, LSRCA, and new-subdivision grading
East Gwillimbury drains straight into the Holland River and Lake Simcoe. That puts it under LSRCA and the provincial Lake Simcoe Protection Plan, where stormwater quality carries more weight than almost anywhere else in the GTA.
Holland River and its tributaries
Properties near the Holland River, its branches, or the associated valley and wetland areas sit inside LSRCA regulated area. Their review of excavation and drainage change precedes the Town.
Lake Simcoe Protection Plan
The provincial plan targets phosphorus reaching Lake Simcoe, and East Gwillimbury sits directly upstream. In practice that favours infiltrating clean runoff on site over piping it to the nearest outlet.
New-subdivision grading plans
Queensville and Sharon are full of recent builds with registered grading plans and inter-lot swales. A drain that changes where water leaves your lot can put you offside the approved plan.

FAQ
Common questions about trench drains in East Gwillimbury
Do I need a permit for a trench drain in East Gwillimbury?
Usually not for the drain itself when we tie into existing private drainage. LSRCA review applies if the property sits inside their regulated area near the Holland River or associated wetlands, and a new municipal storm connection needs a Town permit. Both are confirmed on the site visit.
My house is brand new and water pools against the garage. Is that mine to fix?
Lot grading performance can fall within the scope of a new-home warranty. Lot grading that does not perform can be the builder’s obligation while the home is still in its new-home warranty period, and East Gwillimbury has a lot of very recent construction. We will tell you at the site visit if that looks like your case, even though it means we do not get the job.
Why does the Lake Simcoe Protection Plan affect my driveway?
Because you are directly upstream of the lake. The plan targets phosphorus loading into Lake Simcoe, and clean runoff infiltrated on your own property does not carry it downstream the way piped discharge can. On most lots here a properly sized soakaway is both the compliant answer and the better-performing one.
What does an East Gwillimbury trench drain cost?
Serviced subdivision installs sit in the $1,800 to $4,500 GTA range. Rural properties in Mount Albert and the surrounding country commonly run above it, because building an outlet costs more than connecting to one.
Will a soakaway work here?
It depends on your soil and we assess rather than assume. Sandy material infiltrates well, heavy clay does not, and a soakaway sized wrong will simply back up. Where infiltration will not perform we design a surface outlet with real fall instead.
Do you cover Mount Albert and the rural addresses?
Yes, along with Holland Landing, Sharon, Queensville, Brownhill, and Ravenshoe. Rural addresses are further out, so we book generous fixed windows rather than tight ones we cannot hold.
Can you install in early spring when everything is saturated?
Often that is exactly the right time to look at it, because you can see where the water actually goes. Whether we can install depends on ground conditions — saturated soil complicates excavation and concrete cure. We are straight with you about whether waiting a few weeks gives a better result.
Do you handle commercial work in the Green Lane corridor?
Yes — plaza aprons, loading areas, service bays, and light industrial floors. Quoted after a site visit, with load class set by what actually crosses the drain.
