Construction Holdback in Ontario: What Homeowners Must Retain and Release
Construction holdback is not an optional discount, a permanent deficiency fund or the same thing as a deposit. It is a statutory 10% retention tied to potential construction liens. Since January 1, 2026, Ontario’s current regime also requires annual release of accrued basic holdback through a prescribed notice and payment process.
10%Basic statutory holdback
14 daysAnnual notice after anniversary
60–74 daysAnnual payment window after publication
2 holdbacksBasic plus finishing work
Do not release holdback merely because the contractor says the lien period is over.
The correct date depends on the applicable regime, contract anniversary, publication, substantial performance, completion, termination, last supply and any preserved or perfected lien.

Four amounts commonly confused with holdback
Basic holdback10% of the price of services or materials as they are actually supplied under a contract or subcontract where a lien may arise.
Finishing holdbackAfter substantial performance, a separate 10% holdback applies to the remaining finishing services or materials as they are supplied.
Annual releaseUnder the current regime, accrued basic holdback is released annually following the contract anniversary and prescribed notice process.
Additional deficiency retentionA separate contractual amount, if properly authorized, for unresolved deficiencies. It is not the statutory lien holdback.
The statutory holdback follows the services or materials actually supplied. A separate contractual deficiency amount must be justified independently and should not be disguised as lien holdback.
How the 10% calculation works
Progress invoiceIllustrative CAD $80,000 value supplied before HST and other adjustments.
CAD $80,000 × 10% = CAD $8,000 holdbackCumulative projectIllustrative CAD $600,000 of services and materials actually supplied.
CAD $600,000 × 10% = CAD $60,000 accrued holdbackFinishing workAfter substantial performance, CAD $50,000 of remaining work is supplied.
CAD $50,000 × 10% = CAD $5,000 finishing holdbackNot a depositA 10% opening deposit and 10% holdback serve different purposes and should appear separately.
Deposit ≠ statutory holdbackIllustrations only. The contract price, approved changes, tax treatment, disputed work and actual value supplied must be reconciled from the project records.
The 2026 annual holdback-release process
1Contract anniversaryDetermine the anniversary of the date the contract was entered into.
2Publish within 14 daysThe owner publishes prescribed Form 6 stating the intended annual release amount and payment date.
360-day lien periodLiens for services and materials covered by the annual notice expire on the 60th day after publication unless preserved.
4Pay within 60–74 daysThe owner pays accrued holdback in that statutory window unless preserved or perfected liens prevent payment.
Transition rules matter.
Do not apply the new annual-release steps blindly to every pre-2026 contract or project agreement. Ontario’s transitional regulation preserves former annual or phased treatment in specified circumstances.
Substantial performance, completion and finishing holdback
| Concept | Construction Act meaning | Why it matters |
|---|---|---|
| Ready for intended use | The improvement or a substantial part must be ready for use or actually used for its intended purpose. | One half of the statutory substantial-performance test. |
| 3%-2%-1% formula | Remaining completion and known-defect correction cost cannot exceed 3% of the first CAD $1 million, 2% of the next CAD $1 million and 1% of the balance. | Determines whether substantial performance has been reached. |
| Certificate publication | A certificate or declaration has no effect for these purposes until published as required. | Publication can trigger lien-expiry timing. |
| Finishing holdback | After substantial performance, 10% continues to be retained from remaining services and materials as they are supplied. | Basic holdback release does not eliminate holdback on later finishing work. |
| Deemed completion | The contract is deemed completed when completion, known-defect correction or last-supply cost is no more than the lesser of 1% of the contract price and CAD $5,000. | Can affect lien-expiry and final holdback timing. |

Holdback is not the same as deficiency money
Bad: permanent holdback leverage
“The Owner may retain the statutory holdback until every deficiency and warranty concern is completed to the Owner’s satisfaction.”
Better: separate the two amounts
“Statutory holdback shall be retained and released in accordance with the Construction Act. Any additional amount retained for identified incomplete or defective work must be separately stated, reasonably related to the cost of correction, supported by the Contract and adjusted as deficiencies are completed.”
Educational example only. An Ontario lawyer should adapt payment, set-off, notice, deficiency and release wording to the actual project.
A land-title search is one step—not a complete holdback-release opinion.

Waiting on your holdback? (for trades)
Holdback is your money, held back for a reason that’s supposed to end. Here’s the trade’s side:
- Annual release. On contracts entered into since January 1, 2026, holdback has to be released annually as well as at the end. Older contracts join the annual schedule at their second anniversary after January 1, 2026; contracts from before July 2018 are excluded.
- The owner can’t simply refuse by notice any more. The old notice of non-payment of holdback (s.27.1) was repealed in 2026.
- One preserved lien can freeze the release of the holdback it claims against — for everyone. If another trade liens, ask how it affects your release date.
- Holdback isn’t backcharge money. A backcharge needs notice, a chance to fix and proof of cost; it isn’t a reason to sit on holdback that’s due.
- Holdback disputes can go to adjudication, including whether it should have been released.

Important Ontario legal checks
- Basic holdback: Each payer under a contract or subcontract where a lien may arise retains 10% of the price of services or materials as they are actually supplied.
- Personal exposure: An owner can be personally liable to valid lien claimants for holdback the owner was required to retain, subject to the Act’s limits.
- Mandatory annual release: Under the current section 26, the owner publishes Form 6 no later than 14 days after each contract anniversary and pays the accrued annual holdback 60 to 74 days after publication unless specified lien circumstances apply.
- Publication location: Form 6 must be published on a prescribed construction trade news website.
- Downstream payment: A contractor generally pays the corresponding subcontractor holdback within 14 days after receiving the owner’s annual holdback payment, unless the statutory lien exception applies.
- Termination: After abandonment or termination, the payer cannot use holdback to obtain replacement services or satisfy another claim until applicable liens have expired or been satisfied, discharged or otherwise provided for.
Deadline mistakes can be expensive.
A homeowner should not calculate release from the last invoice alone. Obtain legal advice before annual release, substantial-performance release, termination or any disputed lien situation.

Construction holdback FAQ
What is the 10% holdback?
Every payer in the chain — owner, GC, sub — must keep back 10% of the value of work as it's supplied, until liens against it have expired or been dealt with.
When do I get my holdback?
When liens on the work have expired — and, since 2026, annually on contracts that run past their first anniversary.
How does the new annual holdback release work?
Within 14 days after each anniversary of the prime contract, the owner publishes a notice and then pays the accrued holdback 60 to 74 days later, unless a lien has been preserved or perfected. Each tier must pass it down within 14 days of receiving it.
Does annual release apply to my job?
Contracts made on or after January 1, 2026 start at the first anniversary. Older contracts start at the second anniversary falling after January 1, 2026. Pre-July-2018 contracts are excluded.
Can the owner refuse holdback by sending a notice?
Not any more. The notice of non-payment of holdback (old s.27.1) was repealed in 2026.
Is the owner personally liable for holdback?
Yes — for the holdback they were required to keep, even if they paid the GC in full.
What is the finishing holdback?
A separate 10% retained on work done after substantial performance.
