Answer First: A standard 400 sq ft interlock patio costs about $7,200 to $12,000 installed in the GTA, based on $18 to $30 per square foot for concrete pavers (Ultrascape). Switch to natural stone at $35 to $65+ per square foot and the same patio runs past $14,000. Patios cost less than driveways because they use thinner pavers over a shallower base, and most of what you pay is the excavation and compacted base you never see once the job is done.
A patio quote is easy to misread. The pavers on top are the cheap part. What you are really buying is the eight inches of compacted gravel underneath, and that is where the honest quotes and the lowball ones part ways. YardQuote does not lay patios, which is exactly why it can tell you where the money actually goes.
How much does a paver patio cost in Toronto?
Installed interlock patios run $18 to $30 per square foot for standard concrete pavers across the GTA (Ultrascape), with a typical crew landing near $22. Natural stone is a different tier at $35 to $65+ per square foot. Everything else on the quote hangs off those two numbers.
Here are the real line items that make up a Toronto patio job, pulled from GTA contractor pricing current to July 2026.
| Line item | Low | High | Unit |
|---|---|---|---|
| Interlock patio, installed (standard concrete pavers) | $18 | $30 | per sq ft |
| Natural stone patio, installed | $35 | $65+ | per sq ft |
| Pavers, material only (standard concrete) | $5 | $8 | per sq ft |
| Pavers, material only (premium textured) | $12 | $20 | per sq ft |
| Tearout of old surface incl. disposal | $3 | $6 | per sq ft |
| Decorative border / banding | $3 | $15 | per linear ft |
| Sand & seal (power wash, polymeric sand, sealer) | $1.35 | $2.50 | per sq ft |

The gap between $18 and $65 is not markup. It is material grade and how much digging your yard needs. A stack-and-go patio on flat, well-drained ground sits at the bottom; a stone patio that needs a full excavation and regrade sits at the top.
Quotable: A standard interlock patio costs $18 to $30 per square foot installed in the GTA, while a natural stone patio runs $35 to $65+ (Ultrascape). The pavers themselves are only $5 to $8 per square foot; the rest is excavation, base, and labour.
What does a 400 sq ft backyard patio actually cost?
A 400 sq ft patio, roughly 20 by 20 feet, is the common Toronto backyard size and the easiest way to see where the money goes. Here is a standard build on a lot that needs light prep, using standard concrete pavers.
- Standard concrete pavers, 400 sq ft at $18 to $30: $7,200 to $12,000 all-in.
- Add tearout if you are replacing an old deck or slab, at $3 to $6 per square foot: another $1,200 to $2,400.
- Add a premium border around the perimeter, roughly 80 linear feet at $3 to $15: $240 to $1,200.
- Natural stone instead of concrete, at $35 to $65+ per square foot: $14,000 to $26,000+ for the same footprint.
So the honest spread on one 400 sq ft patio, before HST, runs from about $7,200 for a clean concrete-paver build to well over $20,000 for a full stone install with tearout. Add Ontario's 13% HST on top of whatever number you settle on, because most contractor per-square-foot figures exclude it.
From the data: Of the 503 interlocking contractors YardQuote tracks across the GTA, 464 carry three or more Google reviews, the average rating is 4.75, and 83% of rated companies hold 4.5 stars or higher (YardQuote tracking, July 2026). With that many well-reviewed pros, you do not have to gamble on the cheapest unknown for a fair patio price.
Why is a patio cheaper than a driveway?
Because it carries less weight, so it needs less structure. A driveway holds parked cars, so it uses thick 80mm pavers over a compacted base that can run up to 18 inches deep on a full rebuild (Action Home Services). A patio holds people and furniture, so it uses thinner 50 to 60mm pavers over a 6 to 10 inch base. Less excavation, less gravel, less labour, lower price per square foot.
This is also why you should not let a contractor quote your patio off a driveway spec, or the reverse. If a bid feels high for a simple sitting patio, ask what paver thickness and base depth they priced. A patio built to driveway spec is over-engineered, and you are paying for gravel you do not need.
What drives the price of a paver patio?
Four things move a patio quote more than anything else, and none of them are the pavers on top.
Base and excavation. The compacted gravel base does the structural work. A proper 6 to 10 inch base with geotextile is invisible in the finished patio, which is exactly why cheap bids cut it. Excavation, grading, and base construction are usually the biggest line on the invoice.
Material grade. Standard concrete pavers cost $5 to $8 per square foot in materials; premium textured lines run $12 to $20, and natural stone starts around $25 materials-only (Ultrascape, Project Landscaping). Your material choice can double the per-square-foot number with no change to the contractor's margin.
Tearout and disposal. Removing an old deck, slab, or patio adds $3 to $6 per square foot, plus Toronto tipping fees that keep climbing. One quote folds disposal in; another leaves it out and surprises you on the final invoice.
Site access. A tight downtown semi or a fenced yard with no gate for a mini-excavator means hand-digging and wheelbarrow hauls, which multiplies labour hours. The same patio on a machine-accessible suburban lot prices lower before a single paver is laid.
Do you need a permit for a backyard patio in Toronto?
No. An at-grade patio in your backyard does not require a building permit in Toronto. Permits get triggered by the extras people add around a patio, not the patio itself.
Watch three thresholds. A retaining or seating wall over 1 metre high needs a building permit and engineered drawings under the Ontario Building Code. Any work in the City boulevard or right-of-way needs a separate Landscape Construction Permit from the City of Toronto. And in a front yard without a permitted parking pad, at least 75% must stay soft landscaping, so you cannot pave the whole front as a patio. A backyard sitting patio clears all three without a permit.
How do you keep a paver patio from sinking?
The base decides everything, and maintenance protects it. A patio built on a proper 6 to 10 inch compacted base rarely moves; one built on thin or poorly compacted gravel heaves after a couple of freeze-thaw winters. That is the single most common reason a two-year-old patio needs a $800 to $1,200 minimum repair call.
After it is built, a sand-and-seal every 3 to 5 years at $1.35 to $2.50 per square foot (JHC Landscaping) keeps polymeric sand in the joints and water out. Anywhere you spread de-icing salt near the patio, re-sand every 2 to 3 years, because salt is the main thing that erodes interlock joints in the GTA. Maintenance at a couple hundred dollars beats a full lift-and-relay at $15 to $25 per square foot.
Quotable: The cheapest patio bid usually wins by cutting the base you cannot see. A proper 6 to 10 inch compacted base is why a patio survives Toronto freeze-thaw; skimp on it and you pay again in two winters.
Which patio quote should you actually pick?
Not the lowest, and not the flashiest render. After you confirm every bid covers the same paver thickness, base depth, tearout, and disposal, the honest quote usually sits near the middle. The low outlier is typically the one that quietly dropped the base or left disposal off the sheet.
