Construction Holdback and Lien Act Compliance Review in Ontario

By Bader A. Chowdry, CPA, CA, LPA | Insight Accounting CPA

Construction companies, general contractors, and project owners in Mississauga, Toronto, the Greater Toronto Area (GTA), and across Ontario must comply with the Construction Act (formerly the Construction Lien Act) regarding statutory holdbacks on construction projects. At Insight Accounting CPA, we provide specialized holdback compliance reviews and financial assurance services to ensure your construction projects meet all statutory requirements under Ontario law.

Call (905) 270-1873 to discuss your construction holdback compliance needs.

What is a Construction Holdback?

Under Ontario’s Construction Act, project owners and higher-tier contractors are required to retain a statutory holdback of 10% on each payment made under a construction contract. This holdback serves as security for subcontractors and suppliers who may file construction liens. The holdback must be maintained in a separate account or properly tracked until the applicable lien period expires – typically 60 days after substantial performance of the contract or completion of the subcontract.

For construction companies operating in Mississauga, Toronto, and across the GTA, proper holdback management is critical. Failure to maintain required holdbacks can expose project owners and general contractors to personal liability for lien claims, even if subcontractors have already been paid. Our compliance review at Insight Accounting CPA verifies that your holdback practices meet all requirements of the Construction Act.

What Our Compliance Review Covers

  • Holdback calculation verification – confirming 10% is properly calculated and retained on each progress payment
  • Holdback account management – verifying holdback funds are properly tracked or segregated
  • Lien period monitoring – ensuring holdbacks are maintained for the full statutory period
  • Release procedures – verifying holdbacks are released only after lien periods expire and all conditions are met
  • Prompt payment compliance – reviewing compliance with the Construction Act’s prompt payment provisions effective October 2019
  • Adjudication readiness – ensuring financial records support any potential adjudication proceedings
  • Multi-tier compliance – verifying holdback requirements are properly flowed down to subcontractors

The Review Process

Step 1: Contract and Project Review

We review your construction contracts, project documentation, and payment certification processes for projects in Mississauga, Toronto, the GTA, and across Ontario. We identify all contracts subject to the Construction Act and assess the holdback requirements applicable to each project tier.

Step 2: Holdback Calculation Testing

We test a sample of progress payments to verify that the 10% statutory holdback was correctly calculated and retained. For construction companies in Mississauga, Toronto, and the GTA managing multiple active projects, we verify holdback compliance on a project-by-project basis.

Step 3: Fund Tracking Verification

We verify that holdback funds are properly tracked in your accounting system, with clear separation between operating funds and holdback obligations. For larger construction companies in Ontario, we review trust account or dedicated holdback account management practices.

Step 4: Release and Disbursement Testing

We test holdback releases to confirm they occurred only after the applicable lien period expired and that proper documentation was obtained before release. This protects construction companies in Mississauga, Toronto, and across Ontario from inadvertent lien exposure.

Step 5: Compliance Report

We issue a comprehensive compliance report detailing our findings, any non-compliance issues identified, and recommendations for improving holdback management processes. This report provides assurance to project owners, surety companies, and other stakeholders that your construction company in Mississauga, Toronto, the GTA, or Ontario maintains proper holdback practices.

Prompt Payment Provisions

Ontario’s Construction Act includes prompt payment provisions that require project owners to pay proper invoices within 28 days, and higher-tier contractors to pay subcontractors within 7 days of receiving payment. These provisions apply to all construction projects in Mississauga, Toronto, the GTA, and across Ontario. Our compliance review verifies that your payment processes meet these deadlines and that any notices of non-payment are properly issued within the required timeframes.
