How much does a full interlock paver driveway cost to install in Ottawa compared to asphalt?

A full interlock paver driveway in Ottawa typically costs between $18 and $35 per square foot installed, compared to $8 to $14 per square foot for asphalt. For a standard double-wide driveway of roughly 600 square feet, you're looking at $10,800 to $21,000 for interlock versus $4,800 to $8,400 for asphalt.

What Drives the Price Range

The wide spread in interlock pricing comes down to several factors. Standard concrete pavers from manufacturers like Techo-Bloc or Permacon run $3 to $6 per square foot for materials alone, while premium natural stone or porcelain pavers can hit $12 to $20 per square foot. The pattern you choose also matters — a simple running bond layout requires less cutting and labour than a 45-degree herringbone or a custom fan pattern with contrasting borders.

Ottawa's Frost Demands Add Cost

Ottawa's frost line sits at roughly 1.2 to 1.5 metres deep, and while you don't excavate to full frost depth for a driveway, the Ontario Building Code and industry best practices require a minimum 12 to 16 inches of compacted granular base (Granular A and B) to handle our freeze-thaw cycles. In areas like Barrhaven and Orleans built on Leda clay, contractors often go deeper — 18 inches or more — because clay heaves dramatically when saturated and frozen. This extra excavation and material adds $2 to $5 per square foot compared to milder climates.

Where Interlock Pays Back

The upfront cost stings, but interlock driveways in Ottawa last 25 to 30 years with proper installation and maintenance. Individual pavers can be pulled and replaced if damaged by snowplows or heavy loads, whereas asphalt cracks propagate and require full resurfacing every 15 to 20 years. Many homeowners in Kanata and Nepean report that interlock also adds more curb appeal and resale value than asphalt.

Budget-Friendly Options

If $20,000+ feels steep, consider a hybrid approach: asphalt for the main driving surface with an interlock border and apron at the garage. This popular combo in Stittsville and Gloucester neighbourhoods runs $8,000 to $13,000 and still delivers visual impact.
