How much for a concrete driveway in Ottawa per square foot?

Concrete driveways in Ottawa typically cost $10 to $16 per square foot for standard poured concrete, with decorative finishes like stamped concrete ranging from $16 to $28 per square foot installed.

The wide price range reflects several factors specific to Ottawa's market and climate conditions. Standard 30 MPa air-entrained concrete with wire mesh reinforcement sits at the lower end, while stamped or exposed aggregate finishes with decorative borders and multiple colours command premium pricing. The concrete must include air entrainment (4-7% air content) to survive Ottawa's brutal freeze-thaw cycles — non-air-entrained concrete will spall and scale within 2-3 winters.

Base preparation significantly affects pricing and is critical in Ottawa due to our 1.2 to 1.5-metre frost depth and prevalent clay soils. A proper concrete driveway requires excavation to stable subgrade, followed by a minimum 300mm of compacted Granular B sub-base and 150mm of Granular A base. Properties with Ottawa River valley clay soils often need geotextile fabric between the subgrade and granular base, adding $0.50 to $1.50 per square foot. Contractors who quote significantly below $10 per square foot are likely cutting corners on base depth or concrete specifications.

Reinforcement and thickness also impact cost. Standard residential driveways use 100mm thick concrete with 6x6 welded wire mesh, but heavier vehicle traffic may require 125mm thickness with rebar reinforcement. Control joints must be cut every 3 metres to manage cracking from Ottawa's 60-65 degree annual temperature swings. Stamped concrete requires additional labour for pattern installation and typically needs resealing every 2-3 years to maintain appearance and weather resistance.

For an average Ottawa driveway (45-55 square metres), expect $6,000 to $14,000 total depending on finish and site conditions. Stamped concrete with multiple colours and complex patterns can reach the higher end. Always verify the contractor will use air-entrained concrete mix — this is non-negotiable in Ottawa's climate. Get at least three quotes and ensure each includes proper base preparation, as inadequate base work leads to settling and cracking that becomes apparent after the first winter.

Timing matters for concrete work — it can be placed from late April through mid-November, but avoid periods when overnight temperatures may drop below 5°C during the critical 7-day curing period.
