A backyard transformation in Ontario rarely involves just one element. Use this calculator to budget the full project: patio, wall, planting and any add-ons that matter to you. Real ranges from a working Hamilton-area crew.

How to use this
Three useful patterns:
Start with what is non-negotiable. Set the patio size and paver grade first because for most homeowners the patio is the centrepiece. Then layer in retaining walls (if you have grade), then planting, then add-ons.
Phase the project. If the total is higher than your budget, the calculator helps you see what to defer. Hardscape (patio, walls) almost always goes first; lighting, irrigation and pergolas can be added in later seasons.
Compare scenarios. Try a 25 m² patio with mid-grade pavers vs a 35 m² patio with economy pavers. The total may be similar but the long-term feel of the yard is very different.
What this calculator does not include
- Pool installation. Pool building is its own project category, typically $50,000 to $150,000 separately from the surrounding landscape. See our pool building service.
- Deck construction. If your yard needs a deck rather than a patio (typically because of grade), read our deck vs patio comparison and add $350-$600 per m² for composite decking.
- HST. All numbers are pre-tax. Ontario HST (13%) applies to residential landscape work.
- Site-specific surprises. Heavily compacted clay, buried debris, unusual access constraints can all add cost that no calculator can anticipate.
Frequently asked questions
How accurate is the total budget estimate?
Within roughly 15 to 20% for a typical Ontario residential backyard. The most common reason a real quote falls above the range is a site condition surprise (drainage worse than expected, soil softer than expected, access harder than expected).
Should I phase the project to spread the budget?
Often, yes. Hardscape (patio, walls, drainage) almost always goes first because changing them later requires demolition. Planting, lighting and pergolas can be added in subsequent seasons without disturbing the hardscape.
What is the most common backyard budget bracket?
Most full-backyard transformations in the Hamilton, Halton and Niagara regions land in the $25,000 to $60,000 bracket. Below that is usually a focused single-element project; above that includes premium materials, multiple outdoor rooms or estate-scale work.
Can I get a printed copy of my estimate?
Not from this page directly. Take a screenshot or note the result. When you book a free on-site quote, the calculator output is a great starting point for the conversation.
Does this calculator work for Halton and Niagara projects, or just Hamilton?
All three regions. Costs are reasonably consistent across our service area. Oakville and parts of Burlington tend slightly higher because of larger lots and premium material expectations; St Catharines and rural Halton Hills tend slightly lower or comparable.

Three real 2026 GTA backyard budgets
Numbers straight from our 2026 quote pipeline. Each build reflects a common Hamilton-Halton scenario we see monthly.
Budget A: $18,000 back-yard refresh (Burlington semi, 60 sq m yard)
- New 22 sq m Techo-Bloc Aberdeen patio off the walkout: $8,900
- 1.5 m x 6 m cedar planter and privacy screen (Turkstra Lumber Burlington): $2,200
- 12 sq m sod replacement (Zander KBG blend): $1,240
- Native perennial bed with mulch (Connon Nurseries Waterdown): $1,180
- Serviceberry feature tree + planting: $580
- Site cleanup, disposal and dump fees: $780
- Landscape lighting starter (4 path lights + 2 accent uplights, Volt or Kichler LED): $2,100
- Contingency (10%): $1,020
Turnkey with our crew: 5 to 7 working days. Roughly 40% hardscape, 30% planting, 30% amenity.
Budget B: $42,000 full back-yard rebuild (Oakville detached, 120 sq m yard)
- Full excavation and regrade with drainage tile-in: $6,800
- 60 sq m Techo-Bloc Villagio patio with fire-pit inlay: $19,400
- 1.2 m dry-stack retaining wall (12 linear metres, Techo-Bloc Mini-Creta): $6,200
- Cedar pergola over patio (4 m x 4 m, engineered post base): $5,800
- Sod replacement (35 sq m, Zander KBG): $2,600
- Perennial and shrub bed (Sheridan Nurseries Oakville): $2,900
- Landscape lighting package (12 fixtures, transformer, wired): $3,900
- Permit fees + disposal + contingency: $2,400
Turnkey: 3 to 4 weeks including permit lead time. Deck permit and retaining-wall engineered drawings both required.
Budget C: $85,000 pool-and-patio build (Ancaster, 200 sq m yard)
- 16 x 32 ft in-ground fibreglass pool with equipment pad: $42,000
- 90 sq m stamped concrete pool surround: $16,200
- Pool enclosure fence (60 linear metres, Ontario code-compliant): $8,800
- Landscape lighting (18 fixtures around pool + accent): $5,600
- Native perennial and shrub planting around perimeter: $3,900
- Permit fees + engineered drawings + disposal: $3,400
- Contingency (7%): $5,100
Turnkey: 10 to 16 weeks including permit lead time and pool manufacturer install schedule. This is the top of typical residential back-yard spend in the Hamilton/Halton market.
The 10 hidden cost lines that break DIY budgets
- Disposal. Old sod and concrete rubble haul costs $180 to $420 per bin in Hamilton. Underestimating this by 2 to 3 bins is common.
- Regrading. Anything over 8 cm of grade change costs $500 to $1,500 in labour and imported fill (which is trucked in at $52 to $85 per cubic metre from A. Fanning Ancaster or Beaver Valley Stone Waterdown).
- Base aggregate. 100 mm of limestone screening under a patio at $58 to $72 per cubic metre delivered adds up fast on 40+ sq m patios.
- Polymeric jointing sand. $65 to $110 per 20 kg bag, and a 40 sq m patio needs 4 to 6 bags.
- Edge restraint. $6 to $12 per linear metre plus install for aluminum bender board (Permaloc) or plastic edging.
- Landscape lighting transformer + wiring. Adds $800 to $2,200 even before fixtures.
- Frost-line footing depth. Deck footings 1.2 m deep with sonotubes and concrete cost 3x the surface-only version most DIY plans assume.
- Permit fees. Add $260 to $780 in Hamilton alone.
- Legal survey. $600 to $1,200 in the GTA. Required for anything setback-sensitive.
- Engineer stamp for retaining walls over 1 m. $1,200 to $2,800.
Financing options GTA homeowners actually use
- HELOC (Home Equity Line of Credit). Most common. Rates in 2026 sit around Bank of Canada prime + 0.5% variable. Interest-only payments during construction. Best for $20K+ projects.
- Refinance the mortgage. Locks the rate but adds legal fees ($1,000 to $1,800) and takes 4 to 8 weeks. Only worth it if you are already refinancing anyway.
- Landscaper-financed payment plan. Some Landscape Ontario contractors partner with third-party financing (Financeit, SNAP) offering 12 to 60 month terms. Higher effective rate than a HELOC (typically 8 to 14%).
- Save-and-pay-cash. The lowest-cost route if you can wait a season. A $25K spring-summer 2027 build funded over the 2026 winter costs zero in interest.
