Payment Holdback Required:

Construction or Renovation Relations



Last Updated: August 23 2026

Question: Is it illegal to pay a construction final invoice in full in Ontario without retaining the required holdback?

Answer: In Ontario, paying the final invoice in full without retaining the statutorily required holdback can be unlawful on construction and renovation projects because the Construction Act requires each payer to retain a 10% holdback until all lien claims that can be made against it have expired or been satisfied, discharged, or otherwise provided for; this applies even if the contract says payment on completion, and owners may face liability to unpaid lien claimants.

Statutory Required Payment Holdbacks
Why It Is That Paying the Final Invoice In Full Upon Project Completion Is Actually Illegal

There are likely few times when paying an invoice in full is against the law.  Indeed, failing to pay an invoice in full is usually against the law by constituting as a breach of contract; however, in the realm of construction or renovation, meaning projects to improve a property, paying in full without retaining a holdback may be, and likely is, unlawful.

The Law

The Construction Act, R.S.O. 1990, c. 30, formerly known as the Construction Lien Act, statutorily requires the owner of a construction project or renovation project involving improvements to property, whether residential, commercial, industrial, agricultural, or other type, to holdback ten (10%) percent from payments due until the expiry of the time in which a lien may be preserved.  Furthermore, where a project owner fails to properly holdback payment as statutorily required, the project owner may be held liable for payment to any and all subcontractors, subtrades, suppliers, among others, who were unpaid by the contractor or subcontractors along the chain of supply.  Specifically, the Construction Act states:


Holdbacks

Basic holdback

22 (1) Each payer upon a contract or subcontract under which a lien may arise shall retain a holdback equal to 10 per cent of the price of the services or materials as they are actually supplied under the contract or subcontract until all liens that may be claimed against the holdback have expired or been satisfied, discharged or otherwise provided for under this Act.

Separate holdback for finishing work

(2) Where the contract has been certified or declared to be substantially performed but services or materials remain to be supplied to complete the contract, the payer upon the contract, or a subcontract, under which a lien may arise shall retain, from the date certified or declared to be the date of substantial performance of the contract, a separate holdback equal to 10 per cent of the price of the remaining services or materials as they are actually supplied under the contract or subcontract, until all liens that may be claimed against the holdback have expired or been satisfied, discharged or otherwise provided for under this Act.

When obligation to retain applies

(3) The obligation to retain the holdbacks under subsections (1) and (2) applies irrespective of whether the contract or subcontract provides for partial payments or payment on completion.

Permissible forms of holdback

(4) Some or all of any holdbacks may, instead of being retained in the form of funds, be retained in one or more of the following forms:

1. A letter of credit in the prescribed form.

2. A demand-worded holdback repayment bond in the prescribed form.

3. Any other form that may be prescribed.

Personal liability

23 (1) Subject to subsections (2), (3) and (4), an owner is personally liable for holdbacks that the owner is required to retain under this Part to those lien claimants who have valid liens against the owner’s interest in the premises.

Limitation

(2) Where the defaulting payer is the contractor, the owner’s personal liability to a lien claimant or to a class of lien claimants as defined by section 79 does not exceed the holdbacks the owner is required to retain.

Same

(3) Where the defaulting payer is a subcontractor, the owner’s personal liability to a lien claimant or to a class of lien claimants as defined by section 79 does not exceed the lesser of,

(a) the holdbacks the owner is required to retain; and

(b) the holdbacks required to be retained by the contractor or a subcontractor from the lien claimant’s defaulting payer.

How determined

(4) The personal liability of an owner under this section may only be determined by an action under this Act.

Per the Construction Act as shown above, a ten (10%) percent holdback is required by each party within the hierarchy of a project to improve property, which includes construction or renovation projects.  Accordingly, the property owner is required to holdback ten (10%) percent from the general contractor who in turn is required to holdback ten (10%) percent from subcontractors and so on throughout the various layers of payors to suppliers of the project.  This holdback requirement expires when the risk of a lien being filed against the improved property expires which is, generally, sixty (60) days following completion of the project or completion of substantial performance (which is established by the issuance of a Certificate of Substantial Performance).

Infrequent project owners as laypeople, such as homeowners, may be unaware that upon completion of a the project work, whether the project involves a pool installation, roofing shingle replacement, landscape upgrades, replacing kitchen cabinetry, basement wall waterproofing, or other improvements and renovations, that the ten (10%) percent holdback requirement is mandated by law. Failure to perform the statutory holdback constitutes as a breach of trust whereas the Construction Act creates a trusteeship and the failure to act in accordance with the trusteeship, the homeowner, among others, may be found liable for breach of trust.

Conclusion

Owners of projects, along with everyone throughout the supply chain, from contractors to subcontractors, and so on, are required to holdback ten (10%) percent of payment upon the completion or issuance of a Certificate of Substantial Completion.  Generally, the holdback provision expires after sixty (60) days.
