An honest interactive estimate for an interlocking paver patio in the Hamilton, Halton and Niagara regions of Ontario. Slide the inputs to see your real cost range. The numbers come from hundreds of actual residential projects we have built since 2008.
How much will my patio actually cost?
Move the sliders and pick the options that match your situation. The estimate updates as you change inputs.
Most residential patios in Ontario fall between 20 and 50 square metres. 30 m² comfortably fits a 6-person dining set plus a small lounge area.
Estimated cost range (CAD, 2026):
$7,050 to $9,000
These are realistic ranges for a typical Ontario residential project, based on hundreds of patios we have built in the Hamilton, Halton and Niagara regions. Your actual quote depends on the exact site, materials and design.
What the calculator includes
The base cost covers: site excavation to proper depth (150 to 200 mm of compacted granular base on a typical lot), geotextile separation fabric, the granular base material itself, bedding sand, the paver units (priced per grade), polymeric jointing sand, edge restraints, and skilled installation labour.
What is NOT in the base estimate
Three categories of work can push a project well above the calculated range. The calculator surfaces the most common ones but not every possibility.
- Major drainage rework. Beyond what the "Heavy" drainage option covers. If your lot has serious flooding issues, a full lot drainage fix can be $6,000 to $26,000 on its own before any patio is laid.
- Retaining walls or significant grade changes. A wall to terrace a sloped yard runs $300 to $1,200 per linear metre depending on height and material. See our retaining wall cost guide.
- Permits and engineering. Most residential patios do not need permits, but heritage districts, retaining walls over 1 metre, and work near conservation lands sometimes do. Engineering for taller walls adds $1,500 to $4,000.
- Decorative features beyond the patio surface. Fire pits, outdoor kitchens, low-voltage lighting, garden installation. Each adds its own cost line.
How the numbers work
The calculator is built from rate tables we use internally to scope projects. The base installed ranges are:
| Paver grade | Per sqft (CAD) | Per m² (CAD) |
|---|---|---|
| Economy grey/charcoal | $22 to $28 | $235 to $300 |
| Mid-grade textured or coloured blend | $28 to $34 | $300 to $365 |
| Premium tumbled or intricate pattern | $34 to $40 | $365 to $430 |
Site access adds 0% (easy), 10% (medium) or 25% (hard, hand-carry required). Drainage adds a fixed amount: $1,600 to $3,500 for light work and $4,500 to $12,000 for heavy work. Demolition of an existing surface is $43 to $86 per square metre ($4 to $8 per square foot).
Why these ranges and not a single number
Honest landscaping contractors do not give a single dollar quote without seeing your property. The bottom of each range assumes a forgiving site (level lot, easy access, friendly soil). The top assumes the harder reality (clay soil, restricted access, more design complexity). Your actual on-site quote lands somewhere in the calculated range based on what we find when we visit.
Frequently asked questions
How accurate is this calculator?
It is within roughly 10 to 15% of a real on-site quote for a typical Ontario residential patio. The most common reason a real quote falls outside the range is significant grade change (which adds retaining wall cost) or unexpected sub-base conditions found during excavation.
Is this for Ontario only?
Yes. The cost ranges are for the Hamilton, Halton and Niagara regions of Southern Ontario. Costs in other Canadian markets and in the US will differ, sometimes by 20 to 40%.
What if my project needs walls, planting and lighting too?
Use this calculator for just the patio component. For the full backyard estimate, see our landscaping cost guide which covers multi-element projects.
Does the calculator account for taxes?
No. All numbers are pre-tax. Ontario HST (13%) applies to landscaping work for most residential properties.
Can I save or share the estimate?
