If you’re considering an interlock driveway for your Toronto home, your first question is probably: “How much will this cost?” It’s a fair question—and one that deserves an honest, detailed answer.
Average Interlock Driveway Costs in Toronto (2026)
As a Unilock Authorized Contractor serving Toronto since 2021, we’ve helped many homeowners navigate the investment in an interlock driveway. The truth is, costs vary significantly based on several factors, but we can give you realistic ranges to help you budget.
Bottom line upfront: Most Toronto homeowners invest between $12,000 and $35,000 for a quality interlock driveway installation, with the average double-car driveway costing around $15,000-$20,000.
Let’s break down exactly what goes into that cost—and what you’re actually paying for.

Single-Car Driveway
(200-300 sq ft)
Cost Range: $6,000 – $9,000
Per Square Foot: $30-40
A single-car driveway typically measures about 10 feet wide by 20-30 feet long. This is the most budget-friendly option but still provides all the durability and aesthetic benefits of interlock.
Double-Car Driveway
(400-600 sq ft)
Cost Range: $12,000 – $18,000
Per Square Foot: $30-40
This is the most common driveway size in Toronto. At roughly 20 feet wide by 20-30 feet long, it accommodates two vehicles comfortably.
Large Driveway with Turnaround
(800-1,000 sq ft)
Cost Range: $24,000 – $35,000
Per Square Foot: $30-40
Popular in areas like North York and Etobicoke where lot sizes allow, these larger driveways often include circular turnarounds or additional parking space.
Estate Driveways
(1,500+ sq ft)
Cost Range: $45,000 – $75,000+
Per Square Foot: $30-40
Found in areas like Rosedale, Forest Hill, and parts of North Toronto, estate driveways require more materials and labor but benefit from economies of scale.
What Determines Your Interlock Driveway Cost?
The $30-40 per square foot range exists because several factors
significantly impact the final price. Here’s what affects your cost:
1. Paver Selection and Style
Basic Rectangular Pavers:
$28-35/sq ft
•Simple, clean look
•Fewer cuts required
•Faster installation
•Popular choice for budget-conscious homeowners
Premium Unilock Pavers:
$35-40/sq ft
•Multiple colors and textures
•Unique shapes and sizes
•Enhanced color blending
•Products like Umbriano, Brussels Block, Beacon Hill Smooth
Decorative Patterns and Borders:
Add 15-25%
•Herringbone patterns
•Circular or curved designs
•Contrasting border colors
•Soldier courses
•Inlays and accent features
The paver itself is only part of the material cost—but the design complexity significantly affects labor time.
2. Site Preparation and Excavation
Standard Site: Included in base price
•Relatively flat terrain
•Good drainage
•Easy equipment access
•Clay soil (typical for Toronto)
Challenging Site: Add $2,000-$5,000
•Steep slopes requiring extra grading
•Poor drainage requiring additional drainage solutions
•Difficult access (narrow side yards, back driveways)
•Rocky soil requiring extra excavation
•Tree roots that need removal
Toronto’s clay-heavy soil is actually good for interlock driveways when properly prepared. The excavation depth (12-16 inches below frost line) is critical—this isn’t where you want to cut corners.
3. Existing Driveway Removal
Asphalt Removal: $500-$1,500
•Relatively straightforward
•Can be broken up and removed efficiently
•Disposal costs are moderate
Concrete Removal: $1,500-$3,000
•Requires jackhammering
•Heavier material to haul away
•Higher disposal fees
•More labor-intensive
Old Interlock Removal: $800-$2,000
•Pavers can sometimes be salvaged
•Base material may be partially reusable
•Depends on condition
Many Toronto homes have aging asphalt driveways from the 1990s or early 2000s—these are typically the most cost-effective to replace.
4. Permits and Regulations
City of Toronto Permit: $200-$400
•Required for most driveway replacements
•Requires site plans and drainage calculations
•We handle this process for you
•Approval typically takes 2-4 weeks
The permit cost is relatively small compared to the overall project, but it’s a necessary part of any legitimate installation in Toronto.
5. Additional Features
Heated Driveway System: Add $10,000-$25,000
•Melts snow and ice automatically
•Reduces winter maintenance
•Increases energy costs
•Popular in upscale Toronto neighborhoods
Landscape Lighting: Add $1,500-$5,000
•Adds a luxurious touch
•Improves safety
•Low-voltage LED systems
•Can highlight architectural features
Retaining Walls: $65-$150 per square foot
•Often needed for sloped driveways
•Creates level parking area
•Adds significant aesthetic value
•Commonly paired with driveway projects
Walkway Extensions: $18-$40 per square foot
•Connects driveway to front entrance
•Creates cohesive look
•Often recommended for curb appeal
Why Costs Vary Between Toronto Contractors
You’ll likely receive quotes ranging from $20 to $50+ per square foot. Here’s why:
Low-End Quotes
($20-$24/sq ft) – Red Flags
•Thin base preparation (8-10 inches instead of 12-16 inches)
•Inadequate compaction (leads to settling within 2-3 years)
•Lower quality pavers (non-Unilock products)
•Cutting corners on drainage
•No proper edge restraint
•Cash-only operations (no warranty, no recourse)
•No permits pulled (liability risk for you)
These “savings” often cost you more when the driveway fails in 1-5 years instead of lasting 40+ years.
Mid-Range Quotes
($30-$40/sq ft) – Quality Work
•Proper excavation to correct depth
•Quality base materials and compaction
•Premium pavers (often Unilock)
•Engineered drainage
•Proper edge restraint
•Permits handled
•Multi-year warranty
•Established local business
This is where you’ll find contractors like US—Unilock Authorized with proper training and legitimate business operations.
High-End Quotes
($45-$60/sq ft) – Premium Service
•All quality elements above
•High-end design services
•Complex pattern work
•Premium paver selections
•Extensive project management
•Large company overhead
How Toronto’s Climate Affects Your Investment
Toronto’s freeze-thaw cycles (60+ per winter) make proper installation absolutely critical. Here’s why the investment matters:
Proper Installation = 40+ Year Lifespan
Base depth below frost line prevents heaving
Quality drainage prevents water accumulation
Proper compaction prevents settling
Pavers flex during temperature changes
Poor Installation = 5-10 Year Failure
Inadequate base depth causes frost heaving
Poor drainage leads to ice expansion damage
Insufficient compaction causes uneven settlement
Cracking at stress points
That $5,000 “savings” on a cheap installation means you’ll be replacing your driveway twice in the time a quality installation would last once. The math doesn’t work in favor of cutting corners.
Financing Your Toronto Interlock Driveway

Is an Interlock Driveway Worth the Cost?
Let’s compare the long-term costs:
Interlock Driveway
Initial Cost: $15,000 (double-car)
Lifespan: 40+ years
Maintenance: $200-300 every 3-5 years (sealing)
Total 40-Year Cost: $18,000
Cost Per Year: $450
Asphalt Driveway
Initial Cost: $4,000 (double-car)
Lifespan: 12-15 years
Maintenance: $300-500 every 3-5 years (seal coating)
Resurfacing: $2,000 every 10 years
Replacements: 2 over 40 years ($4,000 each)
Total 40-Year Cost: $16,000-$18,000
Cost Per Year: $400-450
The surprising truth: Over 40 years, the costs are nearly identical—but interlock provides:
•Superior aesthetics and curb appeal
•Easier repairs (individual paver replacement)
•Better resale value (10-15% home value increase)
•No cracking or patching needed
•Salt resistance (Toronto’s heavy salt use destroys asphalt)
