Payment Holdback Required:

Question: In Ontario construction projects, is it illegal for an owner to pay the final invoice in full at project completion without retaining a 10% holdback?

Answer: Yes. In Ontario, the Construction Act, R.S.O. 1990, c. 30 (sections 22 and 23), requires each payer on a contract or subcontract where a lien may arise to retain a 10% holdback until all lien claims against the holdback expire or are satisfied. That obligation applies even if the contract says “payment on completion,” and owners can face personal liability to lien claimants where required holdbacks were not properly retained.   Olson Craig Legal helps Ontario owners, contractors, subcontractors, and suppliers manage Construction Act holdbacks, lien-risk, and payment timing so you can pay correctly and reduce exposure, call (226) 886-2001 for lawyer & paralegal support.

Statutory Required Payment Holdbacks

Why It Is That Paying the Final Invoice In Full Upon Project Completion Is Actually Illegal

In the realm of construction work or renovation projects, paying an invoice in full without retaining a holdback may be against the law. While it is generally perceived that failing to pay an invoice in full is considered a breach of contract, for business within the contracting trades paying an invoice in full is likely unlawful. A holdback from full payment is required for the protection of suppliers who may go unpaid by the party above within the supply chain.

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:

As prescribed by the Construction Act, a ten (10%) percent holdback is statutorily required of each party involved in any property improvement project such as construction projects or renovation projects. Accordingly, the project owner must holdback ten (10%) percent from the full payment when paying the general contractor; and subsequently, the general contractor must then do the same when paying subcontractors, and so on throughout all levels within the labour and material supply chain involved with the project. Once the project is finished or once a Certificate of Substantial Performance is issued and the risk of a lien being placed upon the improved property expires, which is typically sixty (60) days afterward, the holdback requirement ends and payment of the holdback money becomes due.

Interestingly, and most contractors will know this; however, small project owners, such as homeowners as laypeople will unknowing, the homeowner that pays the invoice from a contractor in full upon completion of a renovation contract, whether roofing, landscaping, building an addition, replacing kitchen cabinetry, or other household improvements, is required to holdback ten (10%) percent.  Failing to do so is a breach of trust whereas the Construction Act, statutorily, creates a trusteeship and by failing to act in accordance to the trusteeship, the homeowner, among others, could 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.
