How to Make (and Defend) a Performance or Payment Bond Claim in Canada, Procedure, Notices & Timelines (2026 Practical Guide)

Updated 2026

Performance bonds Canada projects rely on, together with their payment bond counterparts, are the primary financial security instruments that protect owners against contractor default and protect subcontractors and suppliers against non-payment. As public infrastructure spending expands and prompt payment and adjudication regimes take firmer hold across the provinces, more parties are calling bonds and doing so faster than before. This guide sets out, in practitioner-level detail, how to make and defend a claim on a performance or payment bond in Canada, the notices required, the documents to assemble, the timelines that govern each step, the likely costs, and the defences a surety can raise. The focus is Ontario and federal procurement, with clear flags where provincial law differs.

Overview: Performance Bonds Canada Claims Explained

A performance bond is a three-party instrument under which a surety guarantees that a contractor (the principal) will complete its contractual obligations to the owner (the obligee). If the contractor defaults, the surety must generally either arrange completion or pay the obligee the cost of completion, up to the bond limit, in accordance with the bond’s terms. A payment bond, by contrast, guarantees that subcontractors and suppliers who supply labour or materials will be paid; where the contractor fails to pay, those claimants may recover from the surety, provided they fall within the bond’s protected class.

Both bond types appear on public and private construction projects across Canada. On federal contracts, security requirements are set through the applicable federal procurement rules administered by Public Services and Procurement Canada; in Ontario, the interaction between bonds, holdbacks and lien rights is shaped by the Construction Act. This guide covers both the offensive side (calling a bond) and the defensive side (responding as a surety or principal). Because bond wording controls entitlement, the single most important discipline in any performance bonds Canada claim is reading the bond itself before taking any step.

Quick answer, how to call a bond in one paragraph

To call a bond in Canada: locate the bond and confirm the surety, bond number and named beneficiaries; read the bond and contract to confirm you have standing and to identify any condition precedent (such as a prior demand for performance or a notice window); assemble your evidence of default or non-payment (contract, invoices, change orders, correspondence, lien claims); serve any required preliminary or statutory notices; then serve a formal written Notice of Claim on the surety by a traceable method, stating the bond number, contract reference, amount claimed, particulars of the breach and your demand. Follow up promptly, and preserve your lien, adjudication and limitation rights in parallel.

Eligibility, Who Can Call or Be Sued on a Bond

Bond terminology matters. The principal is the contractor whose performance or payment obligation is secured. The obligee is the party in whose favour the bond runs, usually the owner on a performance bond. The beneficiary or claimant is the party entitled to recover, the obligee on a performance bond, and the protected subcontractors and suppliers on a payment bond.

Standing turns on the bond’s own words. An owner named as obligee on a performance bond can call it when the contractor defaults. A subcontractor’s ability to claim on a payment bond depends on whether the bond extends protection to parties in its tier, some bonds cover only first-tier subcontractors and suppliers, others reach further down the chain. Suppliers of labour and materials are frequently within the protected class; parties with no contractual connection to the bonded contract usually are not. Always confirm the claimant is within the class the bond protects before serving anything.

Payment vs performance bonds, who benefits?

Contract wording traps, named beneficiaries and assignment clauses

Two recurring traps defeat otherwise good claims. First, a claimant assumes it is a beneficiary when the bond names only specified parties or a narrower tier than the claimant occupies. Second, a claimant relies on an assigned right without a valid assignment, being owed money by the principal is not the same as being a direct beneficiary of the bond. Where entitlement flows through an assignment rather than direct naming, document the chain of assignment carefully, because a surety will scrutinise it. In every case, the bond wording, not the parties’ assumptions, determines who can recover.

Step-by-Step: How to Make (Call) a Performance Bonds Canada Claim

The following numbered process applies to both performance and payment bond claims, with notes where the two diverge. Each step carries a time-sensitive action; the consolidated timeline table follows immediately after.

1. Identify the bond and confirm the essentials. Locate the bond document and record the surety’s legal name, the bond number, the penal sum (bond limit), the obligee and any named beneficiaries. If you do not hold a copy, common for a subcontractor claiming on a payment bond, request it from the obligee or the general contractor. On federal projects, the security details flow from the procurement documents. You cannot serve a valid claim on a surety you have not correctly identified. This step answers the common question, “How do you make a claim on a performance bond in Canada?”, it always begins with the bond itself.
2. Review the contract and bond to confirm standing and triggers. Read the bond and the underlying contract together. Confirm you are the obligee or a protected beneficiary; identify every condition precedent (for example, a requirement to declare the principal in default, or to make a written demand for performance before the surety’s obligation is engaged); and note any notice window or time bar stated in the bond. A claim served without satisfying a condition precedent is a claim a surety can reject.
3. Calculate amounts owing and assemble supporting documentation. Quantify the claim precisely. For a payment bond, this means unpaid invoices, delivery receipts, payroll records for labour, and approved change orders. For a performance bond, this means the projected cost to complete or correct the work, supported by contract records, schedules and any independent estimates. Weak quantum invites a low counteroffer or an outright denial; assemble the ledger of unpaid or outstanding amounts before you serve.
4. Serve preliminary or statutory notices if required. Some bonds and some provincial regimes require a preliminary notice before a formal claim, for example, a written notice to the principal of non-payment, or a statutory notice tied to lien or holdback rights. In Ontario, coordinate this step with your lien and prompt payment rights under the Construction Act, because the windows are short. Where a preliminary notice is a condition precedent, serving it late or not at all can be fatal.
5. Prepare and serve the formal Notice of Claim on the surety. Draft a clear written notice that includes the claimant’s name, the bond number, the contract reference, the amount claimed, the particulars of the breach or non-payment, and an express demand. Serve it by a traceable method, registered mail or courier with confirmation, plus email, and keep proof of service. If the surety supplies a mandatory claim form, use it. This is the pivotal act in calling a payment bond or performance bond; do it as soon as the evidence is assembled, and never outside any contract-specified window.
6. Follow up: negotiation, demand for performance, or procurement of security. After the surety acknowledges the claim it will investigate. Respond promptly to reasonable requests for proof. On a performance bond, this phase may involve the surety electing to complete the work, tendering a completion contractor, or paying. On a payment bond, it typically involves verifying the amount and negotiating settlement. Keep the pressure and the paper trail consistent throughout.
7. If the claim is denied or ignored, escalate while preserving rights. If the surety denies liability or fails to respond, escalate through the available routes, lien enforcement, adjudication under the applicable prompt payment regime, or litigation. Crucially, preserve every parallel right: do not let a lien preservation or perfection deadline or a limitation period lapse while you await the surety’s answer. Adjudication can produce an enforceable interim determination that strengthens the bond claim.

The durations below are practical estimates only; the operative deadlines are those in the bond wording and the applicable statute, which govern.

Required Documents & Sample Notice Checklist

A well-documented claim moves faster and survives scrutiny. The documents needed differ between a payment bond claim (a subcontractor or supplier proving unpaid amounts) and a performance bond claim (an owner proving default and the cost to complete), but the core package overlaps substantially. Use the checklist below as your assembly list before you serve.

Two short sample notices illustrate the minimum content. A payment bond notice should read, in substance: “Re: Payment Bond No. [____], [Project], [Prime Contract dated ____]. [Claimant] supplied labour and materials to [Principal] and remains unpaid in the amount of $[____], particulars attached. Demand is made under the payment bond for payment of the said amount. Served by registered mail and email on [date]. ” A performance bond notice should read, in substance: “Re: Performance Bond No. [____], [Project]. [Obligee] declares [Principal] in default of [contract obligation], particulars attached, and demands that the surety perform its obligations under the bond or pay the cost to complete, estimated at $[____]. Served by registered mail and email on [date].

” Both should state the name, bond number, contract reference, amount, particulars of breach, an express demand, and the method of service.

Timeline & Deadlines: Limitation Periods, Bond Expiry and Notice Windows

Timing is where good claims are most often lost. Three distinct clocks run in parallel, and each must be tracked separately.

• Bond expiry versus the limitation period. A bond may carry its own expiry date or a clause barring claims made after a stated period. Where the bond contains such a bar, “no claim shall be brought after [X]”, that clause may defeat a claim even if the general limitation period has not run, subject to how a court construes and enforces it. Where the bond is silent on time, the applicable provincial limitation period governs the right to sue. Read the bond’s time provisions first, because they can be shorter and stricter than the statute.
• Provincial limitation periods. In Ontario, the Limitations Act, 2002 establishes a basic limitation period of two years running from the day the claim was discovered, subject to an ultimate limitation period. Discoverability turns on when the claimant knew, or ought reasonably to have known, of the loss and that a proceeding was the appropriate remedy. Other provinces set their own periods, so the applicable period must be confirmed by jurisdiction.
• Prompt payment and adjudication windows. Ontario’s Construction Act reforms introduced prompt payment obligations and interim adjudication, both of which run on tight statutory timelines. Because these windows are short and interact with holdback and lien deadlines, a claimant must move quickly to preserve downstream rights. Missing a prompt payment or adjudication step does not necessarily bar a bond claim, but it can forfeit a fast, enforceable route to establishing entitlement.

The practical rule for any bond claim timeline in Canada is to calendar all three clocks, bond expiry, limitation period and any adjudication or lien window, at the outset, and to treat the earliest of them as the operative deadline. On federal projects, confirm the security and claim provisions in the procurement documents, which set their own requirements.

Costs & Fees

Bond claims range from a single demand letter that resolves in weeks to fully litigated disputes. Budget realistically at the outset and revisit as the matter escalates. Note that some public procurement contracts permit recovery of certain costs, and a surety that pays a claim will ordinarily seek indemnity from its principal under the general indemnity agreement. The figures below are broad illustrations only and vary widely with the forum, complexity and counsel involved.

What Is Changing, Prompt Payment, Adjudication & Procurement Trends

Three developments are reshaping how performance bonds Canada claims proceed. First, increased public infrastructure spending is producing more large, security-backed contracts and, correspondingly, more bond calls. Second, the maturing of prompt payment and adjudication regimes means an adjudicator’s determination can create an enforceable interim right to payment, which a claimant can present to a surety as evidence of entitlement. Third, procurement bond requirements continue to trend toward greater standardisation, particularly on federally administered contracts where security requirements are set centrally.

The practical effect is compression: faster payment cycles mean claimants should preserve rights and serve notices sooner, and sureties are expected to investigate and respond within tighter commercial expectations. The actionable takeaway is to treat adjudication determinations as evidence, attach them to the proof supplied to the surety, and to escalate promptly when an adjudication enforces a payment right, rather than waiting for the surety’s investigation to run its full course.

Defending a Bond Claim, What Sureties and Principals Should Do

A surety or principal facing a claim should respond methodically rather than reflexively. The first task is to verify the bond wording and the named beneficiaries, and to confirm the claimant has standing within the protected class. The second is to demand full proof of claim, invoices, proof of service of any required notices, and evidence of the alleged default. The third, on a performance bond, is to investigate the principal’s alleged default and to consider cure, completion or step-in performance options, which may cost less than paying the full claim.

Typical surety defences in Canada, with response strategies

• Lack of standing or that the claimant is not a protected beneficiary. Response for a claimant: prove direct naming in the bond or a valid, documented assignment.
• Failure of a condition precedent. A required demand or notice was not given, or was defective. Response: cure where the window remains open, or demonstrate compliance where the bond permits.
• Fraud or misrepresentation. The claim rests on inflated or false amounts. Response: produce contemporaneous records and independent verification of quantum.
• Failure to mitigate. The obligee failed to reduce completion costs. Response: document reasonable steps taken and competitive tendering of completion work.
• Release or novation. The obligation was released or replaced. Response: show any release was conditional or unperformed.
• Limitation period or bond time bar. The claim is out of time. Response: establish the discovery date and confirm the claim falls within the applicable period and any bond expiry clause.

Common Pitfalls & Practical Tips

• Not checking who is named on the bond. Serving a claim as a party outside the protected class is a common reason claims fail. Confirm standing before drafting.
• Missing notice windows. Bond and statutory windows can be short and unforgiving. Calendar them the moment you learn of a potential claim.
• Serving a defective notice. A notice missing the bond number, particulars of breach or an express demand invites rejection. Follow the checklist and use the surety’s form where one exists.
• Accepting partial payments without release language. Take payments only under clear, documented terms so that a partial payment does not compromise the balance of the claim.
• Failing to preserve lien and adjudication rights. Do not let a lien preservation or perfection deadline or an adjudication window lapse while awaiting the surety’s response. Run all rights in parallel.
• Assuming the surety will pay without a demand. A surety’s obligation is generally engaged only by a proper demand. Silence is not a claim.

Templates & Jurisdictional Advice

Performance bonds Canada claims turn on precise wording, correct standing and disciplined timing, get any one wrong and an otherwise strong claim can fail. Prepare your Notice to Surety carefully against the specific bond, and obtain jurisdictional advice before serving or responding to any bond claim.
