Change-Order Documentation Compliance

Fast-Fact Summary

• Governing Agency: Ontario Construction Act & CCDC contract administration
• Form, Bylaw, or Regulation: Construction Act, R.S.O. 1990, c. C.30

Mandatory Scope

This compliance requirement applies to all construction trades, general contractors, subcontractors, and project owners operating within Ontario's construction sector. Any change to the original contract scope-regardless of project value, worker count, or trade category-must be formally documented. This includes capturing the directive date, detailed backup documentation, approval authority signatures, and direct invoice connections before any changed work is billed.

Deadlines & Administrative Windows

• Pre-Billing Documentation: All changed work must be fully documented and approved before it is included in any billing cycle.
• 7-Day Invoicing Rule: Invoices containing change-order amounts are legally deemed proper unless the owner delivers a formal written notice of deficiency within 7 days of receipt. Missing this 7-day window forfeits the owner's right to dispute the invoice layout or structure and immediately triggers the 28-day prompt-payment timeline.
• Mandatory Annual Holdback: For contracts extending beyond one year, owners must publish a Notice of Annual Release of Holdback (Form 6) on an electronic construction trade news website within 14 days after each contract anniversary. Accrued basic holdback must be paid between day 60 and day 74 after publication, provided no liens are preserved.
• Repeal of Section 27.1: Payers can no longer publish a notice of non-payment to refuse holdback distribution for deficient or incomplete work. Holdback usage is strictly limited to formal contract abandonment or termination scenarios and preserved lien risk.
• Adjudication Extension: Parties have a strict 90-day window after contract completion, abandonment, or termination to initiate interim binding adjudication through ODACC or a qualified private adjudicator to resolve change-order disputes.

Financial & Legal Liability

• Non-Compliance Penalty: There is no verified statutory fine amount prescribed for change-order documentation omissions. However, poor change-order records directly increase invoice deficiency disputes and payment-delay exposure under the Construction Act.
• Average WSIB Premium Rate: $1.23 per $100 of insurable payroll, down from $1.25 per $100 of insurable payroll.
• G6 Non-Residential Construction Rate: $1.61 per $100 of insurable payroll.
• 2026 Maximum Insurable Earnings Ceiling: $121,700.

Step-by-Step Filing Instructions

• Step 1: Initiate the Change Directive: Document the change immediately upon identification. Record the directive date, specific scope modifications, and the authorizing party.
• Step 2: Gather Backup Documentation: Compile all labour hours, material receipts, and equipment rates associated with the change.
• Step 3: Secure Written Approval: Obtain formal sign-off from the owner or authorized consultant before executing or billing the work.
• Step 4: Link to Proper Invoice: Reference the approved change-order number directly on the proper invoice to prevent 7-day deficiency disputes.
• Step 5: Monitor Holdback and Adjudication Timelines: Track contract anniversaries for Form 6 publication and observe the 90-day post-completion window for ODACC adjudication if payment disputes arise.

2026 Inspection Notes

For 2026 construction compliance context, pay close attention to working-at-heights training records, trenching and excavation controls, and training/competency documentation. Ensure all personnel executing change-order work on-site are fully certified and that their training records are readily accessible for field inspections.
