Canadian construction estimates should be built from pre-tax labour, materials, subcontractors, overhead and profit, then have the applicable GST/HST shown separately. For a registered contractor using the regular method, GST/HST generally applies to the full taxable contract—including both labour and materials—not just the materials. The rate usually follows the province where the building or land is located, and provincial sales taxes can change how materials are costed in British Columbia, Manitoba, Saskatchewan and Quebec.
The practical method is to price the work from current job costs, distinguish recoverable GST/HST from taxes that are a real cost, and apply the correct job-site tax after the pre-tax subtotal. The guide below uses rates current on 13 November 2026; confirm the rules for the specific contract and province before issuing a binding estimate.

Start with the cost of doing the work before sales tax. Build the estimate from realistic labour hours and costs, current material pricing, subcontractors, job-specific expenses, contingency, company overhead and profit. Then calculate the sales tax that applies to the contract and show it as a separate line. This makes the estimate easier to audit and avoids treating tax as either profit or an unexplained markup.
- Labour: estimated hours multiplied by a burdened charge-out rate, not automatically by a published employee wage.
- Materials: current supplier pricing, plus expected waste and delivery. Include non-recoverable PST or RST where it is a cost to the contractor.
- Subtrades: their pre-tax charges, with any applicable non-recoverable tax treated consistently.
- Job-specific costs: mobilization, permits the contractor actually incurs, dumpsters and small tools, as applicable.
- Contingency: a visible allowance for uncertainty such as material movement, site conditions or schedule pressure.
- Company overhead and profit: applied to a clearly defined pre-tax cost base.
- GST/HST and any applicable provincial tax: calculated after the taxable subtotal according to the contract and the location of the property.
Do not add GST/HST paid on purchases to a regular-method registrant’s material cost if it will be claimed as an input tax credit (ITC). Conversely, an unregistered contractor or a contractor using the Quick Method may not recover that tax, so it can be a real cost. The estimate should state whether it is an estimate or a fixed price, how long supplier prices are valid, how allowances will be reconciled, and how any holdback and rebate assignment are treated.

What GST/HST rate applies to a construction job in 2026?
For taxable work on a building or land, the rate generally follows the province where the property is—not the contractor’s shop location. The Canada Revenue Agency (CRA) rate table, current for supplies on or after 1 April 2025, gives the following GST/HST rates. Nova Scotia’s HST fell from 15% to 14% on that date, so older templates should be corrected.
| Job location | GST/HST rate | Separate provincial rate shown in CRA table |
|---|---|---|
| Alberta | 5% GST | 0% |
| British Columbia | 5% GST | 7% PST |
| Manitoba | 5% GST | 7% RST |
| New Brunswick | 15% HST | Included in HST |
| Newfoundland and Labrador | 15% HST | Included in HST |
| Northwest Territories | 5% GST | 0% |
| Nova Scotia | 14% HST | Included in HST |
| Nunavut | 5% GST | 0% |
| Ontario | 13% HST | Included in HST |
| Prince Edward Island | 15% HST | Included in HST |
| Quebec | 5% GST | 9.975% QST |
| Saskatchewan | 5% GST | 6% PST |
| Yukon | 5% GST | 0% |
These rates are drawn from the CRA GST/HST calculator and rate table. Its separate PST column is not automatically the tax to charge on a supply-and-install construction contract. In HST provinces, the invoice normally has one full-rate HST line; do not split it into a 5% federal component and a provincial component.
For example, a contractor based in Gatineau doing a renovation on an Ottawa house generally uses Ontario’s 13% HST rate, while a Halifax electrician working on a Moncton property generally uses New Brunswick’s 15% HST. By contrast, materials sold and delivered without installation generally follow the delivery province, and design or consulting not tied to a particular property usually follows the client’s address. Place of supply also depends on the kind of supply and who receives it; particular exemptions or zero-rated supplies can change the result, so do not assume every residential job is tax-exempt.
Does GST/HST apply to labour as well as materials?
Usually, yes: a registered contractor using the regular method charges GST/HST on the taxable construction contract, including labour and materials. The common belief that labour on a renovation is exempt is not a safe estimating rule. Show the full applicable HST or GST on the taxable contract price after the pre-tax subtotal.
In a province with HST, list one HST amount at the full rate. In a province with 5% GST plus a separate provincial tax, follow the provincial construction rules rather than adding the CRA table’s two percentages together automatically. British Columbia, Manitoba, Saskatchewan and Quebec each need special treatment discussed below. Tax is not contractor profit, and the contractor’s remittance method does not change the tax rate the customer owes.
How do provincial sales taxes affect construction materials?
PST, RST and QST are separate estimating issues, not simply extra percentages to apply to every invoice. The treatment can turn on whether the contract installs goods into real property, whether the goods remain personal property, and who is responsible for buying the materials. The contractor-specific summary below reflects Ridgepole’s 5 October 2026 guide; provincial bulletin PDFs were not reviewed for this article, so confirm the treatment of unusual equipment or mixed contracts with the relevant province or a tax professional.
| Province | Typical construction-estimating treatment | What to avoid |
|---|---|---|
| British Columbia | For a supply-and-install contract that becomes part of the building, the contractor generally pays PST on taxable goods bought for the job and treats it as a material cost. The client-facing tax line on that contract is generally 5% GST. Supply-only sales and non-real-property parts of mixed contracts can be different. | Do not automatically charge 12% on the full contract or show 7% PST on a typical real-property supply-and-install contract. |
| Manitoba | For many real-property contracts, the contractor is treated as the consumer of materials and pays RST on the purchase price; RST does not apply to labour to install materials into real property. Supply-only sales differ. Certain systems and goods that remain tangible personal property can attract RST on materials and installation labour. | Do not use one RST switch for all labour. Mechanical, electrical, appliance and equipment details can change the treatment. |
| Saskatchewan | Construction, alteration, repair and improvement of real property are generally taxable services. The contractor generally collects PST on the total charge, including labour and materials, but not on GST, and can generally buy contract materials exempt for resale using a vendor licence. | Do not both leave PST in the material cost and charge it again to the client when materials were bought exempt for resale. |
| Quebec | QST is generally 9.975% of the selling price before GST. If both taxes apply, calculate 5% GST and 9.975% QST on the pre-GST price; QST is not calculated on top of GST. | Do not stack the QST rate on the GST-inclusive total. Ask about registration and QST input tax refunds. |
| Alberta and the territories | 5% GST applies; there is no provincial sales tax in the CRA table. | Do not add an invented provincial tax line. |
HST provinces—Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador, and Prince Edward Island—use one HST rate for the taxable supply rather than a second provincial tax line. For all jurisdictions, confirm the relevant rule for a supply-only sale, a mixed real-property contract, or a specialized installation before pricing it.

How do you calculate tax on an estimate?
Multiply the pre-tax taxable amount by the relevant rate, then add the tax to the subtotal. If a customer is given a tax-included price, divide by one plus the rate to recover the pre-tax amount, and clearly state that the price includes tax and identify the rate. A separate tax line is usually clearer, especially for business customers that may claim ITCs.
| Location and tax treatment | Pre-tax contract | Tax calculation | Total |
|---|---|---|---|
| Ontario | $10,000 | 13% HST = $1,300 | $11,300 |
| Nova Scotia | $10,000 | 14% HST = $1,400 | $11,400 |
| New Brunswick, Newfoundland and Labrador, or Prince Edward Island | $10,000 | 15% HST = $1,500 | $11,500 |
| Alberta or a territory | $10,000 | 5% GST = $500 | $10,500 |
| Quebec, assuming both taxes apply | $10,000 | $500 GST + $997.50 QST = $1,497.50 | $11,497.50 |
Prices checked November 2026.
These are arithmetic illustrations using the CRA rates, not CRA sample estimates. On the Quebec row, QST is 9.975% of the $10,000 pre-tax amount, not of the GST-inclusive $10,500. For a tax-included Ontario total of $11,300, the pre-tax price is $11,300 ÷ 1.13 = $10,000. The CRA calculator cautions that rounding can make calculated amounts differ from final totals by a cent or two.
How should labour rates be built into an estimate?
A wage table is a baseline for employee pay, not a contractor’s charge-out rate. The rate needs to cover employer costs, non-billable time, business overhead and a margin. A published national charge-out rate should not be inferred from wages alone.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →The Government of Canada’s Job Bank listed the Canada plumber median wage at $34.00 an hour, with a low of $21.00 and a high of $46.00, updated 19 November 2025. Its page covers plumber occupation code NOC 72300 and includes apprentices and journeypersons rather than a single experience level. Provincial medians differ: Quebec $40.00, Saskatchewan $35.00, Nova Scotia $33.00, Ontario $32.50, British Columbia $32.00, Manitoba and Alberta $30.11 and $30.00 respectively, Prince Edward Island $30.00, Newfoundland and Labrador $27.50, and New Brunswick $26.00. Among the territories, Nunavut was $44.82, Northwest Territories $38.58 and Yukon $31.02. The full wage table is available from Job Bank’s plumber wage report.
Job Bank also reports that 82.2% of workers in NOC 72300 receive at least one non-wage benefit. That category includes more than health insurance: it can include employer pension contributions, insurance, leave, sick days, vacation and employer payroll contributions. It is a reminder that hourly wages alone do not equal the employer’s labour cost.
A practical four-part charge-out build
- Choose the wage basis. Use the actual wage for the employee or owner-operator when known, or a trade- and province-specific wage reference as a starting point. Keep apprentice, journeyperson and owner rates separate if their compensation or billable hours differ.
- Add employer burden. Account for payroll contributions, vacation, statutory holidays, workers’ compensation and other employer costs. SendWork’s illustrative guide uses 20% as a floor for an example—not as a measured national burden. Workers’ compensation rates vary by industry and jurisdiction, so use the firm’s actual rate.
- Divide by realistic billable utilization. Paid hours are not all invoiceable: travel, quoting, callbacks, supply runs, weather delays and administration consume time. SendWork illustrates 1,300 billable hours from 2,000 paid hours, or 65%. A seasonal trade may need an annual blended rate that accounts for weaker winter utilization.
- Allocate real overhead, then add margin. Spread vehicle, fuel, insurance, phone, tools, software and unbilled owner time over the same billable hours. Add profit margin after cost and overhead are covered.
SendWork’s Ontario plumber example is explicitly illustrative: a $32.50 wage becomes about $39 after an assumed 20% burden; dividing by 65% utilization yields about $60 per billable hour; approximately $45,000 in annual one-truck overhead adds about $35 per billable hour, bringing cost to around $95; a 15% margin leads to a charge-out near $110. This is a worked scenario, not a national invoice survey or a rate to copy without substituting the contractor’s actual numbers.
The utilization assumption can matter as much as the wage. SendWork’s arithmetic estimates that a $25-per-hour shortfall across 1,300 billable hours means about $30,000 less in annual revenue. The exact result depends on the firm’s actual hours and costs, but the point is to price labour against billable capacity rather than assuming every paid hour will be sold.

How should you price materials and use cost-per-square-foot guides?
Use current supplier quotes for the actual project. Record when the quote was obtained and how long it is valid; include waste, delivery, and a justified contingency. A broad construction-cost benchmark can help test whether an early budget is plausible, but it cannot replace a bill of quantities, a site-specific scope or current trade quotes.
Precedent Developments’ 28 February 2026 guide reproduces Altus Group 2026 Canadian Cost Guide hard-cost ranges. For condominiums and apartments up to 12 storeys, the reproduced ranges per square foot include Greater Toronto Area $245–$390, Vancouver $330–$400, Calgary and Edmonton $305–$375, Winnipeg $305–$375, Ottawa $260–$320, Montreal $275–$335, Halifax $250–$345 and St. John’s $260–$360. For custom-built single-family homes, the same reproduced table gives Vancouver $490–$1,250, Greater Toronto Area $500–$1,130, Calgary and Edmonton $495–$1,135, Halifax $365–$750 and St. John’s $375–$750.
Those are Canadian-dollar hard-cost benchmarks, not complete project prices. As described by Precedent, they exclude land, financing, professional fees, development charges, permits, taxes, contingency, marketing, leasing incentives and developer profit. The floor-area basis is gross floor area measured to the outside face of exterior walls; underground parking should be priced on parking area using its own rate rather than included in the tower’s area. Precedent says to consider the high end where design is premium, the site is constrained, the schedule accelerated, the envelope or mechanical/electrical scope complex, or there are geotechnical, phasing or municipal challenges. Its guide is for early budgeting, not quantity surveying, lender-grade estimating or insurance replacement cost. See the 2026 Canadian construction costing guide for the reproduced ranges and broader context.
Material and labour pricing can move differently by city, building type and schedule. Precedent’s report describes skilled-trade shortages and materials such as steel, cement, engineered wood, aluminum and mechanical/electrical systems as cost risks, while noting that market pressure varies. A 2026 project should therefore state whether a quote is fixed or allowance-based and what happens if supplier pricing changes. A square-foot benchmark that excludes tax must not be presented to a client as tax-included.

When do you charge GST/HST, and when can you claim ITCs?
A business generally must register once its taxable sales exceed the $30,000 small-supplier threshold, measured over four consecutive calendar quarters or in a single calendar quarter. According to the CRA tests summarized by Ridgepole and Gravun, crossing $30,000 in one quarter ends small-supplier status on the sale that crosses the threshold; crossing it over four quarters but not in one quarter generally ends status at the end of the month after the quarter in which the threshold was exceeded. Gravun says registration is expected within 29 days of the first taxable sale after status ends. Confirm the timing with the CRA for the business’s circumstances.
Below the threshold, registration is optional. A small supplier that stays unregistered does not charge GST/HST, but cannot claim GST/HST ITCs; tax paid on materials is therefore a real cost that belongs in the estimate. Voluntary registration can allow ITCs on eligible purchases such as tools, materials, fuel and subtrade invoices, but it also brings collection and filing obligations. If the business may cross the threshold during a project, avoid promising a tax-free final contract that ignores the taxable sale that triggers registration.
Under the regular method, a registered contractor generally claims eligible GST/HST paid on business inputs as ITCs. The supplier’s invoice must support the claim; a bill without the supplier’s registration details where required may not support an ITC. Do not confuse PST or RST with GST/HST ITCs. Provincial tax that is not recoverable as an ITC should be included in the relevant cost.

The estimate or invoice should identify the GST/HST registration account and tax rate. Gravun’s practical invoice checklist recommends including the supplier’s name, registration number, customer, work description, tax rate and amount, and payment terms on every document. The formal information required depends on the invoice amount; consult the CRA’s applicable invoice rules rather than treating a sample account number or an informal checklist as a legal template.
Is the Quick Method a lower tax rate for the customer?
No. The Quick Method changes how an eligible registrant calculates the amount remitted to the CRA; it does not lower the GST/HST charged to the customer. A contractor should still show the applicable 5%, 13%, 14% or 15% customer-facing rate, not the Quick Method remittance percentage.
Under the Quick Method, a registrant generally gives up ITCs on most operating purchases, and the remittance rate is applied to eligible GST/HST-inclusive revenue. The contractor may keep an amount intended to approximate ITCs that would otherwise be claimed. The CRA’s RC4058 guide sets out the eligibility tests and rates. It describes a $400,000 ceiling based on annual worldwide taxable supplies including GST/HST and associated persons, with specified exclusions, and a 1% credit on the first $30,000 of eligible supplies in each fiscal year. The credit cannot be carried forward.
The right method depends partly on the mix of labour and taxable purchases. A labour-heavy firm with few eligible inputs may find the method favourable; a material-heavy contractor can be worse off if it gives up ITCs on substantial purchases. A contractor’s trade label alone does not determine which Quick Method category applies: the CRA guide includes separate rates for services and goods-for-resale situations. If the company makes supplies in multiple provinces, more than one remittance rate may apply. Do not transfer a remittance rate from the tax return to the customer’s estimate.

Tax on a construction holdback is generally charged when the holdback is paid or becomes payable, whichever occurs first—not automatically on every progress draw as if the full contract price were currently payable. Ridgepole’s guide describes this timing under the Excise Tax Act rule for qualifying statutory or written-contract holdbacks. The same broad timing principle is reported for Saskatchewan PST under its construction guidance.
Free tools Windows power users keep installed
One-click scans. No signup required.
If the contract retains 10% of a progress claim, calculate tax on the amount payable now after the holdback, then charge the tax attributable to the held amount when billing its release. But if the holdback becomes payable under the contract before the client pays it, tax can become due at that earlier point. Deposits and holdbacks are different: deposit invoices applied to the price can have GST/HST timing obligations even though holdback tax is deferred. State the holdback percentage, progress-billing basis and release treatment clearly, and confirm the exact contract and provincial rules.
Do not assume every jurisdiction uses a 10% statutory holdback. Markup’s June 2026 compilation lists 7.5% for Manitoba, 15% for Prince Edward Island and no statutory holdback in Quebec, among other differences; these percentages should be confirmed against the applicable statute and contract. Lien deadlines affect cash flow and are separate from the tax rate.

Should a new-housing rebate be deducted from the estimate?
Not by default. New-housing rebates are buyer-side relief and do not change the GST/HST rate on an ordinary repair or renovation estimate. Do not reduce the quoted tax unless the contract actually assigns a qualifying rebate and specifies who claims it.
Ridgepole’s October 2026 guide describes the original federal new-housing rebate as potentially the lesser of $6,300 and 36% of tax paid for qualifying consideration up to $350,000, phasing out to zero at $450,000. It also summarizes a separate First-Time Home Buyers’ GST rebate of up to $50,000, full up to $1 million and phasing out to zero at $1.5 million, subject to agreement, construction and completion dates. Those eligibility details are contract- and statute-dependent; the buyer, builder and accountant should confirm whether a custom build or substantial renovation qualifies and whether the builder is crediting the rebate. Ridgepole also reports a Quebec QST new-housing rebate with separate thresholds. Do not apply rebate figures to an ordinary taxable renovation or present unverified provincial relief as guaranteed.
What should a clear estimate say?
- Whether the price is pre-tax or tax-included; if tax-included, name the applicable rate.
- The property location and applicable tax line—for example, “HST ON 13%,” “HST NS 14%,” “GST 5%,” or separate GST and QST where appropriate.
- The taxable subtotal, each tax amount and the total payable.
- Whether material pricing is a quote, allowance or fixed amount, its quote date, and its validity period.
- Any non-recoverable PST or RST included in material costs, without presenting it as a tax charged to the client unless the provincial rule requires that.
- The contractor’s GST/HST registration number when applicable, plus a sufficient description of work and payment terms.
- Any progress-draw and holdback schedule, including when tax on the retained amount will be invoiced.
- Whether a new-housing rebate is assigned or credited; otherwise, say that no rebate is deducted from the estimate.
Worked example: Ontario supply-and-install renovation
Assume a registered contractor using the regular method is pricing an Ontario house renovation, with no rebate assigned. The figures are illustrative, not a quote:
- 40 labour hours at a firm-specific $110 charge-out rate: $4,400.
- Materials quoted at $3,000 before HST, plus any waste or delivery allowance. If the $390 purchase HST is recoverable as an ITC, the material cost used in the estimate remains $3,000, not $3,390.
- Pre-overhead cost subtotal: $7,400. For illustration, apply 15% overhead and profit to that amount: $1,110.
- Pre-tax contract subtotal: $8,510.
- Ontario HST at 13%: $1,106.30. Total: $9,616.30.
If the same $8,510 pre-tax scope were located in Nova Scotia, 14% HST would be $1,191.40; in Alberta, 5% GST would be $425.50. In Quebec, assuming both taxes apply, GST would be $425.50 and QST would be $848.62 (9.975% of $8,510), for a total of $9,784.12. For a comparable British Columbia supply-and-install contract, the client-facing GST would be $425.50; any PST paid on taxable materials would be a contractor cost included in the material figure, not a 7% client tax line on the $8,510 subtotal.
If a 10% holdback applies, do not treat the full $1,106.30 Ontario HST as payable on the first draw when part of the price is retained. Apply the contract’s holdback and tax timing, then bill tax on the retained amount when it is paid or becomes payable, whichever occurs first under the applicable rule.
Frequently Asked Questions
Can a contractor quote one price that includes GST or HST?
Generally, a tax-included price can be used if the document clearly says that tax is included and identifies the applicable rate. Showing the pre-tax amount and tax separately is usually easier for a customer that may claim an input tax credit.

The tax rate for work tied to a building generally follows the property’s location, but registration obligations can depend on the province’s rules and the contractor’s circumstances. A contractor taking work across provincial borders should confirm registration requirements before accepting the job, rather than assuming its home-province account settles every obligation.
Should an estimate include permit costs?
Include permits the contractor is actually responsible for obtaining and paying as a project cost. If the contractor is only paying a fee as the client’s agent and recovering the exact amount without markup or management fee, the tax treatment may differ; document that arrangement and confirm it with an accountant.
What happens if a material quote expires before the customer approves the estimate?
If the estimate relies on a supplier price that can change, state the quote date and validity window and explain whether the material allowance will be adjusted before work begins. A square-foot benchmark is not a substitute for renewed supplier pricing on the actual scope.
