Ontario Driveway 2026: Asphalt vs Interlock vs Concrete — Costs, Permits and Maintenance

Choosing a driveway material in Ontario means weighing upfront cost against long-term maintenance and freeze-thaw performance.

Material comparison (2-car driveway, ~500 sq ft, GTA 2026):

Material Installed Cost Lifespan Maintenance
Asphalt $4,000-$7,000 20-30 yrs Sealcoat every 3-5 yrs
Interlock $12,000-$22,000 30-50 yrs Re-sand joints every 5-7 yrs
Concrete $8,000-$14,000 40-50 yrs Avoid road salt, crack repair
Gravel $1,500-$3,000 Ongoing Annual top-up

Key notes:

  • Permit required for new curb cut access to municipal road
  • Some municipalities restrict impervious surface area (stormwater bylaws)
  • Asphalt quality indicator: minimum 4" compacted granular base + 3" asphalt depth
  • Concrete: road salt causes surface scaling — use sand-based ice control

Has anyone recently had interlock installed in the GTA? Who did you use and how was the price?
