🇨🇦 Wood-frame platform construction

Construction Cost Estimator & Bill of Quantities Generator for Canada

A real material takeoff for wood-frame construction under the National Building Code of Canada — you price it, we quantify it.

Search for a 'construction cost calculator Canada' and you'll mostly find single-number estimators — enter your square footage, get a $/sqft range for Toronto or Vancouver, done. That's useful for a gut-check, but it isn't a quantity takeoff a lender, contractor or building permit office can actually use. This tool is built for the second question: how many board feet of framing lumber, how much concrete, how many sheets of drywall does your specific house actually need?

Canadian wood-frame construction looks like US framing on the surface, but two real, code-driven differences change the quantities: footings placed below the local frost line (not a shallow US-style footing) and cold-climate wall assemblies built to hit real R-value insulation targets. This generator's Canada recipes carry their own frost-depth footing, weeping tile and sump pump, and dedicated basement/under-slab insulation lines — not the US file's coefficients relabeled in loonies.

You get a real material takeoff — framing lumber, concrete, insulation, HRV/ERV, roofing — organized the same CSI MasterFormat divisions Canadian and US estimators both already use, then you price every line yourself against your own supplier and trade quotes. We don't publish a fabricated per-city $/sqft number pretending to be your bid; local lumber and labor swing too much between Northern BC and Southern Ontario for that to be honest.

What's in a Canada BOQ from this generator

  • Foundation sized for frost-line depth, with weeping tile and sump pump (Canada's real basement-drainage convention)
  • Wall and floor framing in board feet — a real material takeoff, not a $/sqft guess
  • Basement wall and under-slab insulation as its own line, on top of standard wall/roof-cavity insulation
  • HRV/ERV ventilation — mandatory in most provinces, with no US equivalent
  • Roof framing and covering, with wider ice-and-water-shield eave coverage
  • Windows, exterior and interior doors
  • Drywall, paint and flooring, including finished-basement scope where selected
  • Plumbing and electrical rough-in and fixtures
  • HVAC, staircases and garage (if applicable)

Canada Bill of Quantities — Frequently Asked Questions

Is this a cost calculator or a quantity takeoff?
A quantity takeoff — the free tier gives you real, itemized quantities (board feet, concrete volume, insulation area), which you then price with your own current lumber and trade quotes. Most 'construction cost calculator Canada' tools online skip straight to a $/sqft number; this generator shows the material list behind that number instead.
Why does this generator dig deeper foundations than a US wood-frame BOQ?
Frost heave. Water in the soil freezing and expanding can crack a shallow foundation, so Canadian code requires footings below the local frost line — which is why crawlspaces and basements are the default here, not slab-on-grade, and why this generator's Canada foundation recipe is genuinely different from its US one.
Does this tool include real Canadian lumber or labor prices?
No — you enter your own CAD rates for every line. A 2x4 stud can cost meaningfully more in Northern BC than in Southern Ontario, and lumber prices move fast enough that a fixed national figure would already be wrong by the time you read it.
Can I generate a takeoff for a finished basement in Canada?
Yes — choosing basement (finished) adds real drywall, paint and flooring quantities scoped to the basement's footprint, on top of the frost-depth foundation and weeping-tile drainage every basement option already gets.
