Ontario Prompt Payment (Construction)
Ontario prompt payment rules under the Construction Act set invoice deadlines, payment timelines, and adjudication for construction payment disputes.
Quick definition
Ontario Prompt Payment (Construction) means Ontario prompt payment rules under the Construction Act set invoice deadlines, payment timelines, and adjudication for construction payment disputes.
What is Ontario prompt payment?
Ontario prompt payment rules live in the Construction Act. They set standardized timelines for submitting invoices, responding with notices of non-payment, and paying amounts owed down the contract chain on construction projects.
The goal is to reduce long payment delays without forcing every dispute straight to court. Prompt payment works alongside, not instead of, construction lien rights under the same Act.
How the payment clock works
After proper invoicing under the contract and Act:
- Owners must pay within a set period unless they issue a valid notice of non-payment
- General contractors must flow payment to subs within defined timelines after receiving funds
- Proper invoices must include required information or the clock may not start
Treat invoice format as a compliance step, not just accounting.
Adjudication
When parties disagree about payment, Ontario's adjudication process offers a faster dispute path than full litigation for many construction payment fights. Adjudicators can order payment pending final resolution in some cases.
Adjudication notices, deadlines, and scope differ from lien registration. Know both tracks before a dispute hardens.
Prompt payment vs lien rights
| Topic | Prompt payment | Construction lien |
|---|---|---|
| Main tool | Payment order / adjudication | Security on land |
| Typical goal | Get cash moving | Secure debt against project |
| Deadlines | Invoice and notice driven | Registration and preservation rules |
Use strong change orders and progress payment records to support either path.
On the job
Send proper invoices on time. Late or incomplete invoices delay the payment clock.
Track notices of non-payment immediately. They start your response window.
Do not assume prompt payment replaces liens. Calendar lien deadlines separately.
Get Ontario counsel on large disputes. Procedural mistakes are expensive.
Note
This is general info, not legal advice. Prompt payment and adjudication rules depend on contract type, project facts, and legislative updates. Consult an Ontario construction lawyer for project-specific guidance.
