Interlock vs Concrete vs Asphalt Driveway Cost in Ontario (2026)
Here's the short answer for a 2-car driveway (400-600 sq ft) in Hamilton, Burlington and Oakville in 2026: asphalt is cheapest at roughly $4,000-$9,000 and lasts 12-20 years; poured concrete is the middle at $14,000-$24,000 all-in and lasts 25-35 years; interlock is the premium option at $28,000-$48,000 and lasts 25-40 years with invisible repairs. Interlock costs the most up front and over its life, but it lasts longest, repairs without leaving a scar, and adds the most curb appeal and resale value. Below is the honest three-way breakdown, with a comparison table and the use cases where each one wins.
2026 cost snapshot: 2-car driveway
Every quote depends on your exact square footage, access, grade and the amount of old material that has to come out. But for a standard 2-car driveway of 400 to 600 sq ft on a Hamilton, Burlington or Oakville lot, here are the 2026 ranges we see across the three surfaces:
- Asphalt: roughly $4,000-$9,000 ($7-$13/sq ft). Cheapest to install. Lasts 12-20 years. Market-typical context only, Seven Stones does not install asphalt.
- Poured concrete: $14,000-$24,000 all-in. The middle option. Lasts 25-35 years.
- Interlock pavers: $28,000-$48,000 ($55-$80/sq ft). The premium option, most expensive up front and over its life. Lasts 25-40 years.
Notice the spread: interlock can cost six to seven times what asphalt does on day one. That is real money, and it is why so many homeowners start with the price question. The fuller answer is that day-one price is only one of four numbers that matter, the others are lifespan, maintenance and how the surface repairs when something goes wrong.
Full comparison table
This is the head-to-head at a glance for a 2-car (400-600 sq ft) driveway in the Hamilton-Burlington-Oakville corridor:
| Factor | Asphalt | Concrete | Interlock |
|---|---|---|---|
| Install cost (2-car) | $4,000-$9,000 | $14,000-$24,000 | $28,000-$48,000 |
| Lifespan | 12-20 yrs | 25-35 yrs | 25-40 yrs |
| Maintenance | Reseal every 2-4 yrs, crack-fill | Reseal every 3-5 yrs (siloxane) | Polymeric sand top-ups, no sealing needed |
| Repairability | Patch repairs visible; full resurface eventually | Cracks cannot be lifted; saw-cut patch shows | Lift, replace, re-sand, invisible spot repair |
| Looks | Flat black, utilitarian | Clean and uniform; can be stamped or coloured | Texture, colour, pattern; reads as real stone |
| Best for | Tightest budget, short horizon | Mid-budget, durable, low fuss | Forever home, max curb appeal & resale |
The pattern is clear: spend less up front and you trade away lifespan and repairability; spend more and you buy durability, a cleaner repair story and a better-looking surface. There is no free lunch, and interlock is not the cheapest over the long term, it is simply the best surface if quality and longevity are what you are buying.
Asphalt: cheapest, shortest-lived
Asphalt is the budget pick and there is no shame in that. At roughly $7-$13 per square foot it is the only surface most homeowners can put down for under $10,000 on a 2-car drive. It goes in fast, it is forgiving on tight-access lots, and it sheds snow well because the dark surface warms in the sun.
The trade-offs are real, though. Asphalt is a petroleum product, so it stays flexible only while the binders are intact. In Ontario's sun and freeze-thaw it oxidizes, greys out and starts to ravel, which is why it needs resealing every 2 to 4 years and crack-filling as it ages. Even with that upkeep, most residential asphalt drives need a full resurface at 12 to 20 years. Road salt and gas or oil drips accelerate the breakdown. For a starter home or a property you plan to sell soon, asphalt makes sense. Seven Stones does not install asphalt, we include it here only so you can compare all three honestly.
Concrete: the middle option
Poured concrete is the sensible middle ground: roughly half to two-thirds the price of interlock, with a lifespan that rivals it when the slab is built right. At $14,000-$24,000 all-in for a 2-car drive, it is the surface we recommend for homeowners who want decades of service without the interlock price tag. See our full concrete driveway cost guide for Hamilton for the line-item breakdown.
The catch with concrete is that the spec does all the work. A driveway that lasts 25 to 35 years on Halton Till clay needs to be 5 inches of 4000 PSI air-entrained concrete poured over a 6-inch 3/4-clear stone base, with saw-cut control joints and a cure-and-seal applied while it is green. After that, plan to reseal every 3 to 5 years on a siloxane sealer to keep salt out of the surface. Skip the base, the air-entrainment or the joints and you get the cracked, spalled driveways you see all over older subdivisions. Concrete's weak point is repairability: a cracked slab cannot be lifted, so a fix means an epoxy fill that rarely matches or a saw-cut patch that shows a joint forever. Our Hamilton concrete driveway crews pour to that full spec on every job.
Interlock: the premium option
Interlock is the most expensive driveway you can buy, $28,000-$48,000 for a 2-car drive, and it is worth being honest about that. It costs the most on day one and it stays the priciest option over its full life, even after you factor in the resealing that asphalt and concrete need and interlock does not. Anyone who tells you pavers are "cheaper in the long run" is selling, not advising.
What you actually buy with interlock is quality. Each Hamilton interlock driveway is a flexible system of individual Unilock or Techo-Bloc units laid over a deep compacted base with edge restraint and polymeric sand joints. That flexibility is its superpower in Ontario: instead of cracking when the clay heaves, the joints absorb the movement. When a unit does get stained or a section settles, you lift the affected pavers, top up the base, re-lay and re-sand, and the repair is invisible because the colour runs all the way through the stone. No fading, no patch lines, 25 to 40 years of service, and the strongest curb appeal and resale lift of the three.

Halton clay & freeze-thaw
Ontario throws two things at every driveway: 60-plus freeze-thaw cycles a winter and heavy de-icing salt. On the Halton Till clay under most Hamilton, Burlington and Oakville lots, the ground heaves and settles 25 to 75 mm across a season. How each surface copes with that movement is the real durability story.
- Asphalt flexes when warm but goes brittle in the cold, so winter is when most cracks open. Salt and water then work into those cracks and widen them.
- Concrete is rigid, so it relies on saw-cut control joints to crack where you want it to rather than randomly. Air-entrainment is what lets it survive salt and freeze-thaw without spalling.
- Interlock is the only flexible-by-design system. The joints between units are the flex points, which is exactly why pavers ride out clay movement that cracks rigid surfaces.
Which one wins by use case
- Tightest budget, selling within 5-7 years: Asphalt. Lowest day-one cost, and you will not be around for the reseal-and-resurface cycle.
- Mid-budget, want decades of low fuss: Concrete. Long lifespan at a fraction of interlock's price, as long as it is poured to spec.
- Forever home, 15-plus year horizon: Interlock. Longest life, invisible repairs, no fading, best resale.
- Maximum curb appeal in the $1M-plus market: Interlock. Premium pavers photograph and show far better than flat black or grey.
- Tight access where a bobcat cannot fit: Asphalt or concrete, both are less labour-intensive than hand-laying pavers on a cramped lot.
- Steep or sloped driveway: Interlock or concrete; asphalt can scuff and soften on steep grades in summer heat.
