How much does interlocking cost per square foot in Ontario?
Ontario and GTA contractors put professionally installed interlocking in a band of about $15 to $35 per square foot in 2026, depending on design, access and material. Material-only stone prices look lower, often $5 to $10 per square foot, but they leave out excavation, base, labour and finishing. For the full paving picture, see our driveway paving statistics and asphalt driveway cost guide.
1. Ontario averages $18 to $22 per sq ft installed
Project Landscaping interviewed Landschaft Construction and Alterra Landscaping in January 2026 and puts the average interlock install in Ontario at $18 to $22 per square foot. That assumes a project of at least 500 square feet, about 3 feet of machine access and stone that does not exceed $7 per square foot (Project Landscaping).
2. GTA residential interlocking runs $15 to $25 per sq ft
UltraScape's March 2026 GTA guide puts professionally installed residential interlocking at $15 to $25 per square foot. Online material-only prices of $5 to $10 per square foot do not include excavation, base preparation, drainage, labour or finishing (UltraScape).
3. Most GTA driveways land at $18 to $35 per sq ft all-in
Conscape Canada puts most professionally installed interlock driveways in the GTA between $18 and $35 per square foot in 2026, including excavation, base preparation and pavers. Entry-level pavers sit at the low end; large-format premium pavers, borders and multi-tone designs push toward the top (Conscape Canada).
4. Interlock stone material alone costs about $5 to $7 per sq ft
Project Landscaping puts average interlock stone material at $5 to $7 per square foot, with high-end brands such as Techo-Bloc reaching about $20 per square foot for the stone alone. Driveway stone is typically 80 mm thick, while walkway and patio stones can be 50 mm, a difference of up to about $2 per square foot (Project Landscaping).
5. Labour is about 40% to 55% of the project
UltraScape says labour accounts for about 40% to 55% of total interlocking project costs in 2026. Complex patterns, curves, decorative borders and tight site access all raise labour time (UltraScape).

What does a full interlocking driveway cost?
Full driveway quotes in Ontario usually land between about $10,000 and $45,000 or more, depending on size, paver grade and how much old surface must come out. York Region and Toronto quotes often sit above Brampton and Mississauga for the same scope.
6. Single-car driveways cost about $12,000 to $22,000
MSD Contracting puts a single-car interlocking driveway in Ontario at $12,000 to $22,000 installed in 2026 with quality concrete pavers on a properly engineered base (MSD Contracting).
7. Double-car driveways cost about $20,000 to $42,000
MSD puts a standard double-car interlocking driveway at $20,000 to $42,000 with concrete pavers. Natural stone double-car driveways run about $22,000 to $55,000. Conscape puts many two-car projects of 500 to 700 square feet between $10,000 and $22,000 (MSD Contracting; Conscape Canada).
8. York Region double-car driveways often run $24,000 to $48,000

Which paver materials last the longest?
Concrete pavers are the common Ontario choice. Natural stone and porcelain cost more and often last longer. Sealing and joint sand keep concrete looking newer for longer.
10. Concrete pavers cost about $15 to $30 per sq ft installed
Project Landscaping puts concrete pavers at $15 to $30 per square foot installed, with a lifespan of 25 to 50 years when cared for. It recommends sealing every 3 to 5 years and re-sanding joints every few years (Project Landscaping).
11. Natural stone runs about $25 to $45 per sq ft installed
Natural stone such as granite, limestone and flagstone typically costs $25 to $45 per square foot installed, with a lifespan over 50 years and light maintenance, according to Project Landscaping (Project Landscaping).
12. Porcelain pavers cost about $20 to $40 per sq ft
Porcelain pavers run about $20 to $40 per square foot installed, with a 50-plus-year lifespan and no sealing required in Project Landscaping's comparison. Installation needs more precision than standard concrete pavers (Project Landscaping).
13. MSD puts standard concrete at $12 to $18 per sq ft
MSD Contracting lists standard concrete pavers at $12 to $18 per square foot installed, premium textured or large-format concrete at $16 to $25, and natural stone at $22 to $45. A 1,000 square foot double-car driveway can therefore span roughly $12,000 to $45,000 (MSD Contracting).
14. Properly built driveways last 25 to 40+ years
MSD says a properly installed interlocking driveway with 12 to 18 inches of compacted granular A, edge restraints and polymeric sand should last 25 to 40 or more years in Ontario. Pavers themselves rarely fail first; base failure and missing edge restraints do (MSD Contracting).
15. Unilock offers a transferable lifetime residential guarantee
Unilock warranties the structural integrity of its concrete paving stones and retaining wall units for residential use under a transferable lifetime guarantee, including reasonable use of sodium chloride de-icer on covered products (Unilock). Ask your contractor which brand and warranty apply to your quote.

What drives cost under the surface?
Base depth, old surface removal and drainage decide whether a driveway lasts decades or heaves in a few winters. Low quotes often cut the base you cannot see after the pavers go down.
16. Driveway bases often need 12 to 18 inches of granular A
MSD specifies excavating to a minimum of 12 inches, and often 14 to 16 inches on heavy clay soils common in Brampton, north Mississauga and parts of York Region. UltraScape says driveways need 12 to 18 inches of excavation, while patios and walkways need about 6 to 8 inches (MSD Contracting; UltraScape).
17. Removing old asphalt or concrete adds $3 to $6 per sq ft
UltraScape says removing an existing asphalt or concrete surface adds about $3 to $6 per square foot. MSD puts full driveway removals at about $1,500 to $4,500 depending on thickness and access (UltraScape; MSD Contracting).
18. Permeable pavers cost about 15% to 20% more
Project Landscaping says permeable interlocking systems that let water drain through the surface cost about 15% to 20% more than standard pavers, or about $20 to $35 per square foot installed. Maintenance includes occasional vacuuming to keep joints clear (Project Landscaping).
19. Heated interlocking systems add $15 to $50 per sq ft
UltraScape puts heated interlocking add-ons at about $15 to $35 per square foot. Project Landscaping puts electric heating cables under paver driveways at $19 to $50 per square foot, or about $8,000 to $20,000 for a standard two-car driveway, with winter operating costs of $100 to $800 (UltraScape; Project Landscaping).

How long does interlocking take, and does it add value?
Most residential driveway installs finish in under a week of crew time, not counting permits or weather delays. Curb appeal is a major reason GTA homeowners choose interlock over asphalt. After install, plan to reseal and maintain the surface on a schedule that matches your sealer.
20. A typical driveway takes 3 to 5 days
Project Landscaping puts a typical driveway at 3 to 5 days, a standard patio at 2 to 4 days and a walkway at 1 to 2 days. MSD says a double-car driveway takes 3 to 5 days for a full crew, and vehicles should wait 24 to 48 hours after polymeric sand is activated (Project Landscaping; MSD Contracting).
21. UltraScape cites a 10% to 15% property value lift
UltraScape's FAQ states that professionally installed interlocking often increases property value by about 10% to 15% through curb appeal and durability. Treat that as a contractor-published estimate, not an appraisal (UltraScape).
22. MSD cites 80% to 120% cost recovery in many GTA neighbourhoods
MSD says a well-executed interlocking driveway with matching walkway and front steps returns about 80% to 120% of installed cost in assessed property value in most neighbourhoods, according to contractor and real estate industry estimates (MSD Contracting). Actual resale results vary by street and buyer.
Midpoints of Project Landscaping ranges (1 to 2, 2 to 4, and 3 to 5 days).
