A Notice of Non-Payment is the formal statutory notice from an Owner (or a General Contractor) to the next party down the construction pyramid stating that the recipient's Proper Invoice will not be paid in whole or in part. Our free Canadian template is drafted to satisfy the strict 14-day notice window under Ontario Construction Act s.6.4(2) (post-1 January 2026 amendments), Alberta PPCLA s.32.2, and Saskatchewan Prompt Payment Construction Act, 2024, with optional Expert add-ons for the statutory compliance schedule, the itemised setoff particulars, the ODACC / ARCANA adjudication referral, and the lien preservation reminder.

A Notice of Non-Payment is the formal statutory notice required under the provincial prompt-payment construction legislation when a payer (Owner, General Contractor, or Construction Manager) wishes to withhold all or part of the amount stated on a Proper Invoice received from the next party down the construction pyramid. Without the Notice within the statutory 14-day window, the payer is obligated to pay the entire Proper Invoice amount — even where the underlying work was defective.
In Ontario, the Construction Act was substantially amended by Bills 216 and 60 with major changes effective 1 January 2026. Under the post-2026 regime: the Owner must pay a Proper Invoice within 28 days of receipt (section 6.4(1)); if the Owner does not pay in whole or in part, the Owner must give the Contractor a Notice of Non-Payment within 14 days of receipt (section 6.4(2)); failure to give the Notice within the 14-day window obligates the Owner to pay the entire Proper Invoice. The 2026 amendments also introduced a Proper Invoice DEEMING rule under section 6.1: an invoice is deemed to be a Proper Invoice unless the Owner gives a written notice of deficiency within 7 days of receipt.
Either party may refer the Disputed Portion to adjudication under section 13.5 and Ontario Regulation 264/25 section 19(1), which expressly identifies Notice of Non-Payment disputes as a prescribed matter for adjudication. The Ontario adjudication body is the Ontario Dispute Adjudication for Construction Contracts (ODACC). Adjudication delivers a binding determination within roughly 30 days, typically at 5-10% of the cost of court litigation.
Our Notice of Non-Payment template covers every element a Canadian construction-law practitioner would expect.
Sender legal name, address, phone, email, role (Owner / GC / Construction Manager), signatory name and title.
Recipient legal name, address, role (GC / Subcontractor / Sub-Subcontractor).
Project name, site address, governing province, prime contract date, original contract value.
Invoice number, invoice date, date received by Sender (the 14-day clock starts here), Proper Invoice amount, work period covered.
Undisputed portion (payable within the 28-day prompt-payment window) and Disputed Portion (subject of this Notice).
Specific dated reasons for non-payment — defective work, scope dispute, deficient documentation, prior lien claim, setoff against deficiencies.
Province-specific section references — ON s.6.1 / s.6.4(1) / s.6.4(2) / s.6.5 / s.13.5; AB s.32.1 / s.32.2 / s.33 / s.33.3; SK 2024 Act; with optional Ontario 1 January 2026 Proper Invoice deeming-rule note.
Line items + amounts + rationale + supporting evidence — turns the Notice from a bare assertion into an adjudication-ready record.
Formal notice triggering ODACC (Ontario) / ARCANA (Alberta) adjudication referral with the 90-day commencement window.
Province-specific lien preservation window (60 days Ontario / Alberta / Nova Scotia / NB; 45 days BC; 40 days SK / Manitoba) with substantial performance and last supply dates.
Follow these steps to draft a Notice that satisfies the strict statutory timing and procedural requirements under the provincial prompt-payment regime.
Invoice number, invoice date, date received by Sender. The 14-day Notice window runs from the date the Sender received the Proper Invoice — not from the invoice date itself.
The 14-day window is calendar days, not business days. If received on 2 June, the Notice must be given by 16 June. Missing the deadline by even one day obligates the Sender to pay the entire Proper Invoice.
The Sender must still pay the undisputed portion of the Proper Invoice within the 28-day prompt-payment window. The Disputed Portion is the only amount withheld and subject of this Notice.
Each item being withheld should be separately identified with the amount attributable, the rationale, and (where possible) supporting evidence (inspection reports, third-party quotes, photographs).
Documents the procedural compliance — cites the specific province-specific Construction Act sections, the deeming rule (Ontario post-2026), and pre-empts the most common defensive argument that the Notice was procedurally defective.
Converts the Notice from a bare assertion into an adjudication-ready evidentiary record. Each line item should be supported by documents (inspection reports, third-party quotes, photographs, witness statements).
Gives formal notice of intent to refer the Disputed Portion to ODACC (Ontario) or ARCANA (Alberta) if the dispute is not resolved within the good-faith discussion window. Triggers the Recipient's incentive to engage in pre-adjudication discussions.
Each province specifies the methods of service. Ontario Construction Act section 7 permits service by personal delivery, registered mail, courier, electronic transmission (where the contract so provides), and any other prescribed method. Keep proof of service.

The provincial prompt-payment construction legislation is detailed and the timing requirements are strict.
This template is for informational purposes only and does not constitute legal advice. Construction prompt-payment disputes have significant financial and lien-preservation consequences. Consult a qualified Canadian construction lawyer in your jurisdiction for advice specific to your situation, particularly where: the disputed amount exceeds CAD 100,000; the project is in a regulated sector (public infrastructure, federal works); the Notice will trigger an adjudication referral; or lien preservation deadlines are approaching.

The Ontario Construction Act, R.S.O. 1990, c. C.30 was substantially amended by Bills 216 and 60 with major changes effective 1 January 2026. Key sections: section 6.1 defines Proper Invoice and contains the new 7-day deeming rule (an invoice is deemed to be a Proper Invoice unless the Owner gives written notice of deficiency within 7 days of receipt). Section 6.4(1) requires the Owner to pay the Proper Invoice within 28 days of receipt. Section 6.4(2) requires the Owner to give the Contractor a Notice of Non-Payment within 14 days of receipt if the Owner does not pay in whole or in part. Failure means the Owner is obligated to pay the entire Proper Invoice. Section 6.5 contains the Contractor cascade (must pay Subcontractors within 7 days of receiving payment from Owner). Section 6.6 contains the Subcontractor cascade. Section 13.5 + Ontario Regulation 264/25 section 19(1) provide for adjudication of disputes including Notice of Non-Payment disputes.
The Ontario Dispute Adjudication for Construction Contracts (ODACC) is the adjudication body for Ontario construction-prompt-payment disputes (odacc.ca). Adjudication must be commenced no later than 90 days after the contract is completed, terminated or abandoned, unless the parties agree otherwise. Section 19(1) of Ontario Regulation 264/25 prescribes matters for adjudication including: the valuation of services or materials; payment under the contract (including in respect of a change order); a dispute that is the subject of a Notice of Non-Payment under Part I.1; and payment of a holdback under section 26. Adjudicator fees are set on a sliding scale based on the disputed amount; total cost is typically 5-10% of court-litigation cost.
The Alberta Prompt Payment and Construction Lien Act, R.S.A. 2000, c. P-26.4 (PPCLA) establishes the Alberta prompt-payment regime. The Owner must pay a Proper Invoice within 28 days of receipt (section 32.1). If the Owner disputes the invoice in whole or in part, the Owner must issue a Notice of Dispute within 14 days of receipt of the Proper Invoice (section 32.2). Cascade payment obligations apply for Contractors and Subcontractors (section 33). Adjudication is provided by the ADR Institute of Alberta's Adjudication Roster for Construction in Alberta (ARCANA — adralberta.com/prompt-payment). The Alberta regime is materially similar to the Ontario regime, with some procedural differences.
The Saskatchewan Prompt Payment Construction Act, S.S. 2024, c. 22 establishes the Saskatchewan prompt-payment regime with 28-day owner payment, 14-day notice of non-payment, cascade payment obligations, and adjudication. The Saskatchewan regime came into force in 2025 and applies to construction contracts entered into thereafter.
British Columbia has no enacted prompt-payment legislation as at June 2026. Payment disputes are governed by the contractual rights of the parties under the prime contract, the common law of contract (including the doctrines of set-off and abatement), and the BC Builders Lien Act, S.B.C. 1997, c. 45. The Sender of a withholding notice in BC must rely on contractual or common-law rights rather than a statutory framework. BC introduced draft prompt-payment legislation in 2023 but it has not been enacted.
Manitoba introduced prompt-payment amendments to The Builders' Liens Act in 2023 (C.C.S.M. c. B91) but the amendments are not yet fully in force. New Brunswick is studying prompt-payment legislation. Nova Scotia, Newfoundland and Labrador, and the territorial provinces continue to rely on traditional Builders' / Mechanics' Lien Acts without prompt-payment overlay. The Sender of a Notice in these provinces should consult with a local construction lawyer on the applicable timing and procedural rules.
Bill 60 (in force 1 January 2026) made significant changes to the Ontario lien preservation regime. Most importantly, the annual holdback release is now separated from lien expiry — contractors and subcontractors are no longer required to register liens on an annual basis to preserve their lien rights. Lien expiry remains tied to the milestones in section 31 of the Act: 60 days from publication of the certificate of substantial performance, completion, abandonment or termination of the contract, or where applicable date of last supply. The Expert Lien Preservation Reminder records the 60-day window for the Recipient's information and protects the Sender from a later "we did not know" argument.
Quebec is governed by the Civil Code of Québec and has no Construction Act / Builders' Lien Act equivalent. Quebec's construction-payment framework relies on contractual rights, legal hypothecs under CCQ articles 2724-2732, and a distinct procedural code. A separate Quebec-specific Notice of Non-Payment template will follow in a future sprint.
