Applications for Payment and Holdback in Canada (CCDC 2)

Published: July 1, 2026 Reading time: 13 min By: Issued for Interns

Every month on a construction project, the contractor sends in a bill. The architect reviews it, decides how much to certify, and tells the owner what to pay. Some of that money is held back on purpose — and it does not come back until a very specific event happens later in the project.

This is the payment cycle under CCDC 2. The ExAC tests it from multiple angles: who prepares what, who signs what, what gets withheld, and what triggers the release. This article explains the full process in plain language so you can answer those questions fast on exam day.

Step one: the application for payment

The contractor sends an application for payment — sometimes called a progress draw or progress application — once a month. This is the contractor's invoice. It says: "here is how much work we have done, please pay us this amount."

Under CCDC 2, the contractor sends this to both the owner and the prime consultant at the same time, on the agreed day each month. It must include:

A good practice is for the contractor to share a draft of the progress draw with the consultant before the formal submission. This lets both parties sort out disagreements about how complete the work is before the clock starts. With Ontario's prompt payment legislation, the contractor can be paid even if the consultant and contractor disagree — the owner issues a notice of non-payment for any disputed amount only.

The schedule of values

The application for payment is organized around the schedule of values — also called the contract breakdown. This is an itemized list of all the work on the project, each item assigned a dollar value. It is how the consultant evaluates how much work has been done each month.

The schedule of values should be reviewed and accepted before the first application for payment arrives. A few things to watch for:

Step two: the certificate for payment

After reviewing the application, the consultant issues a Certificate for Payment (CfP). This is the consultant's certified statement of how much the owner is required to pay the contractor for that payment period.

The amount on the certificate does not have to match the amount on the application. The consultant evaluates what they have actually seen on site and certifies accordingly. If the amounts differ, the consultant must explain why — and the owner may need to issue a notice of non-payment to the contractor for the disputed amount.

The body of the certificate works through a simple calculation:

  1. Start with the original contract price
  2. Add any signed change orders and the undisputed value of any change directives
  3. This gives the adjusted contract amount
  4. Multiply by the percentage of work completed to date = the gross amount earned
  5. Subtract statutory holdback (10%)
  6. Subtract all previous payments
  7. The result is what is owed this month (plus HST in Ontario)
Key rule: A consultant can only certify what they have seen. If the consultant has not been doing regular site visits since construction began, they cannot certify payment. This is not optional — it is a hard rule under CCDC 2.

Be careful about both extremes. Over-certifying means the owner has paid out more than the work is worth — if the contractor then defaults, that money is gone. Under-certifying chokes the contractor's cash flow, which can slow the project or push the contractor into financial trouble. Either way, the consultant is exposed to claims from both sides.

What is statutory holdback?

Every time the owner pays the contractor, they keep 10% back. That 10% is called the statutory holdback. It comes from the Construction Act (Ontario), not from CCDC 2. The holdback protects subtrades and suppliers — if the contractor fails to pay them, they can make a lien claim against the holdback funds.

The owner holds 10% back from the contractor. The contractor, in turn, holds the equivalent back from each subcontractor. The subcontractors hold it back from their sub-subtrades. The holdback flows through every level of the payment chain.

The holdback must be kept in a separate trust account. The owner cannot use it for anything else while it is being retained. It is not the owner's money to spend — it belongs to the people who did the work, protected until the lien period closes.

If the owner fails to retain the full 10%, they are personally liable to lien claimants for the shortfall. In the worst case, this means paying twice — once to the contractor, and again to the subtrades who were not paid. The duty to retain holdback is strict.

The exam number to remember: Statutory holdback = 10% of each progress payment, required by the Construction Act. Failing to retain it exposes the owner to personal liability.

When does holdback get released?

Holdback is not released all at once. It comes in stages tied to specific project milestones.

Basic holdback — released after substantial performance

The largest portion is the basic holdback. It covers all the work done up to the point of substantial performance. Here is how it gets released:

  1. The contractor applies for a determination of substantial performance.
  2. Under CCDC 2, the payment certifier (usually the consultant) has 20 days to respond.
  3. If approved, a Certificate of Substantial Performance is published in a construction trade newspaper. In Ontario, this is required by the Construction Act and starts the lien period.
  4. The lien period runs for 60 days after publication for general contractors. Subcontractors and sub-subtrades have 45 days from the last day they supplied work or materials.
  5. After the lien period, if no liens have been registered (or all liens have been vacated or satisfied), the owner can release the basic holdback to the contractor.
The two-step lien process: Registering a lien and keeping a lien are two different things. Step 1 is to preserve the lien — register it at the land registry office within the 60-day (or 45-day) window. Step 2 is to perfect the lien — commence a court action within 150 days of the lien being preserved. A lien that is preserved but never perfected expires and is of no legal force. The Construction Act extended the perfection period from 90 days (under the old Construction Lien Act) to 150 days.

Finishing holdback — released after completion

After substantial performance, the remaining work (the final few percent of the job) creates a separate pot of holdback money called the finishing holdback. This is released after the work is fully complete and another lien period — 60 days from the publication of a Certificate of Completion — has expired without liens.

Holdback type Covers Released after
Basic holdback All work up to substantial performance 60-day lien period expires after Certificate of Substantial Performance is published
Finishing holdback Work done after substantial performance 60-day lien period expires after Certificate of Completion is published

How is substantial performance calculated?

Knowing that substantial performance exists is not enough. You need to know the exact formula used to calculate it, because the ExAC will ask you to apply it.

Under the Construction Act, a project reaches substantial performance when two things are both true:

  1. The project is suitable for its intended use, and
  2. The total value of incomplete or deficient work is at or below the statutory threshold.

The threshold is calculated using a sliding scale tied to the contract price:

Memory trick: 3 – 2 – 1. The percentages drop as the dollar amount goes up. The first million is watched most closely.

Here is a worked example. The contract price is $3,000,000:

If the remaining work and deficiencies on a $3,000,000 contract cost less than $60,000 to complete, and the building is usable, substantial performance has been reached.

On a larger contract — say, $5,000,000 — the threshold is $30,000 + $20,000 + $30,000 = $80,000. The bigger the project, the larger the dollar amount of work that can remain, but the smaller it is as a percentage of the overall price.

Substantial performance vs substantial completion — they are not the same

This is one of the most common mix-ups on the ExAC. These two terms sound similar but they come from different laws and mean completely different things.

Substantial Performance Substantial Completion
Governed by Construction Act (provincial) Ontario Building Code
What triggers it Project is suitable for its intended use AND the value of incomplete or deficient work is below the threshold set in the Act Building meets the occupancy requirements in OBC Division C 1.3.3.1(3)
What it does Starts the lien period; triggers release of basic holdback Allows the building department to issue an occupancy permit
Financial component? Yes — tied to value of work remaining No — purely about safety and building code compliance
Who determines it Payment certifier (usually the consultant) Building department (after inspections)
Memory hook: Substantial Performance = money (Construction Act). Substantial Completion = occupancy (Building Code). One is about paying out holdback. The other is about unlocking the door.

Trust rights under the Construction Act

The Construction Act gives everyone on the project two separate sets of rights: lien rights and trust rights. Most people know about liens. Fewer know about trusts — and the trust provisions are arguably more powerful.

Here is how the trust obligations work:

The key difference between trusts and liens: breach of trust is strict liability. You do not need to prove that someone intended to misuse the money. If a contractor pays their own bills before paying subtrades, they have breached their trust obligation — full stop. This matters for the architect because project financing and payment certification are both caught by the trust provisions, and any interference with those trusts creates exposure.

ExAC shortcut: Liens attach to the land. Trusts attach to the money. Both run in parallel. A subtrade with a strong lien claim also has a trust claim — and can pursue either or both.

Prompt payment

As of October 1, 2019, Ontario's prompt payment rules apply to all construction contracts. The rules set hard deadlines at every level of the payment chain:

Day Event
Day 0 Contractor submits a proper invoice to the owner
Day 28 Owner must pay the undisputed amount — or issue a written Notice of Non-Payment explaining the disputed portion
Day 35 Contractor must pay subcontractors (within 7 days of receiving payment from the owner)
Day 42 Subcontractors must pay their sub-subcontractors (within 7 days of receiving payment from the contractor)

If the owner fails to pay and has not issued a Notice of Non-Payment, the contractor can — after giving 7 days' written notice — suspend work. If a Notice of Non-Payment is issued, the dispute can be referred to adjudication.

Adjudication is handled by the Ontario Dispute Adjudication for Construction Contracts (ODACC). An adjudicator's determination is delivered within 30 days and is binding on both parties until the end of the project — even if one party disagrees. It is a fast-track process designed to keep money flowing while disputes are sorted out. Either party can appeal through the courts afterward.

Note: The prompt payment rules interact directly with the payment certification process. The 28-day clock starts when a proper invoice is received — not when the certificate for payment is issued. The consultant's 20-day response window under CCDC 2 fits inside this timeline.

Change orders and unsigned changes — a payment trap

Only include signed change orders in the certified amount. A change order that has not been signed by both the owner and the contractor is not yet part of the contract — it cannot be included in a certificate for payment. The same goes for proposed changes: do not certify against their value until they are settled.

If a contractor proceeds with work under an unsigned change order or a proposed change, they do so at their own risk. The contract has not officially changed. Any such work can be treated as deficient.

Materials not yet on site

Under CCDC 2, payment is normally triggered when materials are delivered to the site. Many owners modify this with a supplementary condition. The contract should be clear on when payment for materials is allowed and who is responsible for storage, security, and insurance until the materials are incorporated into the building.

The Certificate for Payment represents the minimum the owner is required to pay — not the maximum. The owner can choose to pay more, but they do not need the consultant's permission to do so.

Frequently asked questions

What is the difference between an application for payment and a certificate for payment?

An application for payment is the contractor's invoice — a request for money. A certificate for payment is the consultant's response — a certified statement of how much the owner must pay. The amount on each does not have to match. If they differ, the consultant must explain why.

What is statutory holdback in Canada?

Statutory holdback is 10% of the value of each progress payment, withheld from the contractor under the Construction Act. It protects subtrades and suppliers. The owner holds it back from the contractor; the contractor holds the equivalent back from each subcontractor. It is kept in a separate trust account and not released until the lien period has expired.

When is holdback released in Canada?

The basic holdback (for work up to substantial performance) can be released after the lien period expires — 60 days after the Certificate of Substantial Performance is published. If no liens are registered in that period, or all registered liens are vacated or satisfied, the owner can release the holdback to the contractor.

What is the difference between substantial performance and substantial completion?

Substantial performance is a financial and legal milestone defined by the Construction Act. It triggers the release of statutory holdback and the lien period. Substantial completion is a building code milestone — it is linked to occupancy and the issuance of an occupancy permit. They are separate events, governed by different legislation.

Can the consultant certify payment for work they have not seen on site?

No. Under CCDC 2, a consultant can only certify what they have seen. If the consultant has not conducted site reviews since the beginning of construction, they cannot certify payment or determine substantial performance.

How is substantial performance calculated under the Construction Act?

The Construction Act uses a sliding-scale formula. The threshold for remaining or deficient work is: 3% of the first $1,000,000 of the contract price, plus 2% of the second $1,000,000, plus 1% of the balance. If the remaining work costs less than that amount to complete and the project is usable for its intended purpose, substantial performance has been reached. On a $3,000,000 contract, the threshold is $60,000.

What is the difference between preserving a lien and perfecting a lien?

Preserving a lien means registering it at the land registry office within the statutory time limit — 60 days for general contractors, 45 days for subcontractors. Perfecting a lien means commencing a court action to enforce it, which must happen within 150 days of preservation. A lien that is preserved but not perfected expires. Both steps are required to make a lien enforceable.

What are trust rights under the Construction Act?

The Construction Act creates trust obligations at every level of the payment chain. The owner holds project financing and certified payment amounts in trust for those who do the work. The contractor holds money received from the owner in trust for subcontractors. Subcontractors hold money received from the contractor in trust for their sub-subcontractors. Breach of trust is strict liability — no intent is required. Trust rights and lien rights run in parallel and are independent of each other.

What are Ontario's prompt payment timelines?

Under Ontario's prompt payment rules, effective October 1, 2019: the owner must pay within 28 days of a proper invoice (or issue a Notice of Non-Payment); the contractor must pay subcontractors within 7 days of receiving payment (Day 35); subcontractors must pay their sub-subcontractors within 7 days of receiving payment (Day 42). If the owner fails to pay without issuing a Notice of Non-Payment, the contractor may suspend work after 7 days' notice. Disputes are resolved through adjudication at ODACC within 30 days.
