How Much Does It Cost to Build a House in Canada?

How much does it cost to build a house in Canada per square foot?

Construction-only cost typically runs $150–$300 per square foot for a production-style build and $200–$400+ per square foot for a custom build, before land and soft costs — with Ontario and major-city custom builds running considerably higher (Ontario custom: roughly $375–$550/sq ft; downtown Toronto or Vancouver custom: $515–$1,130+/sq ft). On top of the per-square-foot construction figure, budget another 20–35% for permits, development charges, design fees, and site servicing — these industry-range figures are estimates only; get a firm quote from a local builder for your specific lot and design before committing to a budget.

Key Takeaways

Construction-only cost ranges roughly $150–$400+/sq ft nationally, with Ontario and major-city custom builds running considerably higher than the national average.
Soft costs — permits, development charges, design fees, and site servicing — commonly add another 20–35% on top of the raw construction cost.
Land is a separate, market-dependent cost not included in per-square-foot construction estimates — see our land-buying guide for what that adds.
A construction (draw) mortgage releases funds in stages as the build progresses and converts to a standard mortgage once complete — different from a regular home-purchase mortgage.
These are industry-range estimates, not a quote — construction costs vary by trade availability, material choices, and local permitting, so get a firm quote from a local builder before finalizing a budget.

Buying the land first?

This page covers construction cost once you have a lot. If you're still shopping for land, see how to buy land in Ontario for financing, land transfer tax, and the zoning/servicing checks to do before you buy.

Construction cost figures on this page are industry-range estimates for informational purposes only, not a quote.

Construction Cost Per Square Foot by Region

"Cost to build" varies more by region than almost any other housing figure in Canada, driven by local labour rates, material transport costs, and provincial building code requirements that affect minimum energy-performance standards. This page shows the provinces and major cities with the most reliable published cost data — it isn't an exhaustive province-by-province breakdown, and if your province isn't listed, use the national baseline as a starting point and confirm with a local builder.

Industry-range construction cost estimates, as of September 2026. National figures are cross-checked against Altus Group's annual Canadian Cost Guide; regional and city figures are broad industry ranges, not quotes. The Toronto/Vancouver "production" range sits below the Ontario provincial range because it blends in higher-density, standard-format urban builds — which achieve lower per-sq-ft costs through scale than a detached suburban production home — alongside lower-rise construction; it is not a like-for-like comparison to a single-family suburban build. All figures are hard construction cost only — they exclude land, HST, permits, and other soft costs (see the section below) — get a local builder's estimate for your specific project.
Region	Production-Style Build	Custom Build
National baseline	$150 – $300 / sq ft	$200 – $400+ / sq ft
Ontario	$300 – $400 / sq ft	$375 – $550 / sq ft
British Columbia	$200 – $280 / sq ft	$280 – $500+ / sq ft
Quebec (Montreal area)	$220 – $300 / sq ft	$280 – $380 / sq ft
Toronto / Vancouver (major city)	$200 – $315 / sq ft	$515 – $1,130+ / sq ft

Worked Example: A 2,000 Sq Ft Home

This example intentionally uses a wider $200–$450/sq ft range than the pure national baseline above — it blends production-style and mid-to-upper custom builds into one illustrative scenario, since most real projects fall somewhere between those two categories rather than at one extreme. Applying that range to a 2,000 sq ft home, then adding roughly 25% in soft costs, gives a rough total excluding land:

Illustrative range for a 2,000 sq ft home, excluding land. The true figure for any specific project depends heavily on region, finish level, and lot conditions.
Line Item	Low Estimate	High Estimate
Construction cost (2,000 sq ft × $200–$450/sq ft)	$400,000	$900,000
Soft costs (permits, design, development charges — ~25%)	$100,000	$225,000
Land (separate — highly market-dependent)	Varies	Varies
Total, excluding land	$500,000	$1,125,000

What Adds Cost Beyond the Per-Square-Foot Price

Development and building permit charges. Vary enormously by municipality — high-growth areas often charge substantial development fees to fund infrastructure.
Design and engineering fees. A fully custom architectural design costs more than working from a pre-approved production builder plan.
Site servicing. A well and septic system on an unserviced lot, or a longer hydro/utility run, both add cost a fully serviced urban lot doesn't have — see our land-buying guide for the serviced-vs-unserviced trade-off in more detail.
HST on new construction. New home construction is generally subject to HST, with a partial rebate available on homes under a certain value threshold — confirm current eligibility with the CRA or your builder.
Financing and carrying costs during the build. Interest on a construction mortgage's drawn balance, plus any bridge costs if you're carrying both a current home and the build simultaneously.

How a Construction (Draw) Mortgage Works

A construction mortgage differs from a regular home-purchase mortgage in how the money is released. Instead of one lump sum at closing, the lender advances funds in stages — commonly at the foundation, framing, enclosure (roof and windows installed, "weathertight"), and completion milestones — with an inspection confirming each stage before the next draw releases. You typically pay interest only on the portion drawn so far, not on the full approved amount, which keeps carrying costs lower during construction than they would be on a fully-funded mortgage sitting mostly unused. Once the home is complete and an occupancy permit is issued, the loan converts to a standard mortgage on its regular amortization schedule.

The minimum down payment schedule doesn't change

An insured construction mortgage follows the same minimum down payment rules as any home purchase — 5% on the first $500,000 of the projected completed value, 10% on the portion up to $1.5 million. Model your minimum down payment and CMHC premium with the down payment calculator using your projected finished-home value, then confirm what income that mortgage requires with the mortgage qualifier calculator.

Build vs. Buy: How to Actually Compare

The honest comparison isn't "cost per square foot to build" against "average resale price per square foot" in isolation — it's your total build cost (land + construction + soft costs + financing during the build) against the price of an equivalent existing home in the same neighbourhood, adjusted for the fact that a new build typically needs less near-term maintenance and comes with new-home warranty coverage an older resale home doesn't have. Model your specific numbers rather than relying on a national average, since the gap between building and buying moves significantly by city and even by neighbourhood within a city.

Frequently Asked Questions

Construction-only cost typically runs $150–$300/sq ft for a production-style build and $200–$400+/sq ft for a custom build, before land, permits, development charges, and other soft costs. On a 2,000 sq ft home, that's roughly $300,000–$600,000 in construction cost alone at national mid-range figures — regional costs vary enormously, and land, financing, and soft costs typically add another 20–35% on top.

It depends heavily on your market and what you're comparing to. Building gives you a new, code-current home built to your specifications, but land, development charges, financing costs during construction, and the risk of overruns are all on top of the construction cost itself. Buying an existing home avoids those variables but means accepting its age, layout, and condition. In markets where resale prices are already elevated relative to construction cost, building can be competitive or cheaper; in markets where land is scarce and expensive, buying existing is often cheaper. Run both scenarios with real numbers before deciding — the answer isn't the same in every city.

Through a construction (draw) mortgage, which releases funds in stages as construction milestones are completed — typically at the foundation, framing, enclosure (roof/windows), and completion stages — rather than as one lump sum at closing like a regular mortgage. You generally pay interest only on the funds drawn so far during construction, and the loan converts to a standard mortgage once the home is complete and an occupancy permit is issued. The minimum down payment schedule for an insured construction mortgage follows the same rules as any home purchase: 5% on the first $500,000, 10% on the portion up to $1.5 million.

Land (if you don't already own it), a survey and soil/geotechnical testing, development and building permit charges (which can be substantial in high-growth municipalities), architectural or engineering design fees, a well and septic system if the lot isn't serviced, landscaping and a driveway, HST on new construction (with a partial rebate available on lower-value builds), and financing/carrying costs during the build itself. Together these commonly add 20–35% on top of the raw construction cost per square foot.

A custom home typically takes 8–14 months to build once construction starts, after a design and permitting phase that itself can run 3–6+ months depending on the municipality and how customized the design is. Production-builder homes on a pre-approved plan are often faster, since the design and permitting work is already done for the model. Weather, material and trade availability, and permit processing times in your specific municipality all move this timeline meaningfully.
