Land Grading in Toronto — Yard, Driveway, Lot

We handle land grading Toronto homeowners actually need: re-pitching yards that drain back toward the house, fixing driveway slopes that pond, and re-grading lots after additions, pool digs, or basement underpinning. Toronto’s older housing stock — Leaside bungalows, East York semis, Etobicoke wartime homes — was built when grading codes were loose, and decades of patio additions and soil settlement have made it worse. OCM is a Toronto excavation contractor that grades by laser and shoots elevations before we touch a shovel. Call 416-317-3090 for a free site visit.

Why Toronto Lots Need Re-Grading So Often

Most of the calls we take in Toronto involve negative grading — soil sloping toward the foundation instead of away from it. Houses built between 1900 and 1960 across Riverdale, the Junction, Bloor West, Davisville, and Lawrence Park were graded for the original footprint. Decades of mulch top-ups, garden beds against the wall, new walkways, sunken patios, and tree-root heave have flipped the pitch the wrong way. After a heavy rain you get water in the basement, efflorescence on the foundation, or mushy soil at the wall.

The Ontario Building Code calls for a minimum 2% slope away from the foundation for the first 1.8 m, and we aim for that whenever the lot allows. On narrow downtown lots — Cabbagetown, Little Portugal, Roncesvalles — that target is sometimes impossible without a swale, a French drain, or a catch basin tied to the rear yard. We tell you which lever to pull and why.

Land Grading Services We Do in Toronto

• Foundation re-grading — strip negative slope at the wall, rebuild positive pitch, restore lawn or stone.
• Lot grading certification work — rough grade and final grade ready for a surveyor’s lot grading certificate.
• Driveway grading — fix puddling, re-pitch toward the street, prep base for asphalt or interlock.
• Backyard re-grading — pitch the lawn away from the house and toward a swale, drain, or rear lot line.
• Post-construction grading — clean up after an addition, dig-out, underpinning, or pool build.
• Swale cutting — shape a shallow drainage channel along the side yard so water leaves the property.
• Topsoil and sod prep — final 75–100 mm of clean topsoil, raked, rolled, ready for sod or seed.

Our Toronto Grading Process

We start with a site visit. We walk the lot with you, look at where the water shows up, check the foundation wall for staining, and shoot elevations with a laser at the house, the property lines, and any low spots. From there we build a grading plan: how many cubic yards of soil come out, how many come in, where the new high and low points sit, and whether we need a swale or a drain to make it work.

On the day, we strip the existing sod and topsoil, cut or fill the subgrade to the design elevations, compact, then bring back clean screened topsoil and finish-grade by laser. A typical Toronto backyard re-grade runs 2 to 4 days depending on access — laneway lots in Leslieville take longer than wide North York drives. We protect any trees within Toronto’s tree by-law threshold (30 cm DBH, Chapter 813) and stay outside the tree protection zone unless an arborist sign-off is in place.

Toronto Neighbourhoods We Grade Most

We work across Toronto and most of the surrounding GTA. The pre-war neighbourhoods generate the most grading work because that’s where the foundations are oldest and the slopes have drifted furthest from their original design. We see this constantly in Leaside, East York, the Beaches, High Park, Bloor West Village, the Annex, Davisville, and Forest Hill. North York and Scarborough — Don Mills, Willowdale, Bayview Village, Agincourt, Birch Cliff — bring a different problem: 1960s and 1970s subdivision lots where the original swale between houses has filled in over fifty years. Etobicoke lots along Mimico Creek and the Humber often need engineered drainage on top of regrading because of clay subsoil that holds water.

Outside Toronto, we cover the rest of the GTA — see our service areas page for the full list.

What Land Grading Costs in Toronto

Every lot is different, but here is the honest range we see in Toronto. A small foundation re-grade along one wall of the house — strip, re-pitch, and re-sod about 4 to 6 m of frontage — usually lands in the $2,500 to $5,000 range. A full backyard re-grade with imported topsoil, swale, and new sod is more typically $6,000 to $15,000 depending on lot size, access, and disposal volume. Driveway re-grades depend on whether we’re prepping for asphalt or just cutting the base. Lots that need a catch basin, French drain, or sump tie-in run higher. We give a written quote after the site visit — no guessing over the phone. Call 416-317-3090 to book one.

Why Toronto Homeowners Pick OCM

• We shoot elevations with a laser before we quote — you get real numbers, not a sales pitch.
• We are an excavation crew first. Grading is what we do every week, not a side service.
• We know Toronto Building’s rough-grade and final-grade expectations and we work to them.
• We respect Chapter 813 tree protection zones and won’t dig where we shouldn’t.
• We clean up. Disposal, sod scraps, broken concrete — gone when we leave.

Frequently Asked Questions

How do I know if my Toronto lot needs re-grading?

The clearest signs are water in the basement after rain, puddles that sit for hours next to the foundation, efflorescence (white powder) on the basement wall, soggy lawn near the house, or soil visibly sloping back toward the building. If you see two or more of these, the grade is working against you. We can confirm with a laser shot in about an hour.

Do I need a permit to re-grade my yard in Toronto?

Minor regrading on your own property generally does not need a building permit, but Toronto Building requires a lot grading certificate on new builds and major additions, and you cannot change drainage in a way that pushes water onto a neighbour. If a protected tree (30 cm DBH or larger) sits in the work zone, you need a permit under Chapter 813. We’ll flag any permit triggers before we start.

How long does a backyard re-grade take?

Most Toronto backyard re-grades take 2 to 4 working days. A simple strip-and-repitch along one foundation wall can be done in a day. Larger lots with imported soil, a swale, and new sod can run a week. Laneway access, narrow side yards, and disposal trucking add time — we tell you the realistic schedule when we quote.

Will re-grading stop water from coming into my basement?

Often yes — bad grading is the most common cause of basement leaks in older Toronto homes. But if the foundation itself is cracked, the weeping tile is collapsed, or the city storm sewer is backing up, grading alone won’t solve it. We’ll tell you honestly during the site visit whether grading is the full fix or only part of one.

Can you grade around mature trees on my property?

Yes, but carefully. Toronto’s tree by-law (Chapter 813) protects private trees 30 cm DBH and larger, and we don’t cut into a tree’s critical root zone without an arborist sign-off. In most cases we adjust the grading plan around the tree — feathering the slope, using a low retaining course, or routing a swale wider — so the tree stays healthy and you stay onside.

Do you work outside Toronto?

Yes. We cover most of the GTA — Vaughan, Markham, Richmond Hill, Mississauga, Oakville, Burlington, Newmarket, Aurora, and more. See our service areas page for the full list of cities we serve, or call 416-317-3090.
