Buying or selling a home rarely goes exactly to plan. A roof repair promised before closing might not be finished. A new build might have outstanding deficiencies. A seller might owe money to a contractor who filed a construction lien. In each of these situations, a holdback clause in Ontario real estate transactions gives both sides a practical tool: instead of refusing to close or suing after the fact, a negotiated sum is set aside and released only once the agreed condition is met.

If you have ever seen a dollar amount held in a lawyer's trust account on your statement of adjustments and wondered what it was for, this article explains the mechanics, your rights, and the risks.

What Is a Holdback Clause?

A holdback clause is a contractual term — written into an Agreement of Purchase and Sale (APS) or added by way of an amendment — that directs a portion of the purchase price to be held back from the seller at closing. The money sits in a neutral trust account (almost always the real estate lawyer's trust account) and is released to the seller, or to the buyer as compensation, only when a defined condition is satisfied.

The clause should specify:

Vague language causes most holdback disputes. A clause that says "seller shall complete all repairs" without naming the repairs and setting a deadline is an invitation to litigation.

Common Scenarios Where Holdbacks Arise

Seller Has Not Completed Agreed Repairs or Upgrades

This is the most frequent situation. During negotiations, a buyer asks the seller to fix something — a leaking basement, a failed HVAC unit, faulty wiring flagged in the home inspection. The seller agrees, but closing is in three weeks and the work is not yet done. Rather than collapsing the deal, the parties agree on a holdback equal to the estimated cost of the repair (sometimes with a modest buffer for overruns). Once the seller provides proof of completion — usually a paid invoice and a re-inspection — the funds are released.

Items Missing from Closing

A seller might have promised to leave appliances, window coverings, a garage door opener, or other chattels. If those items are missing on closing day, a holdback can be agreed upon to cover their replacement value. This is often negotiated on the spot, with lawyers handling the paperwork remotely.

New Construction Deficiencies

In new-build transactions, buyers conduct a pre-delivery inspection (PDI) and receive a deficiency list. Some builders and purchasers agree to a closing holdback for outstanding deficiencies rather than delaying the closing date. Note that Tarion warranty coverage also applies to new construction — a holdback does not replace your Tarion rights, but it can provide faster recourse for items the builder has committed to fixing on a specific timeline.

Construction Act Statutory Holdback

This is a different animal entirely. Under Ontario's Construction Act, owners who engage contractors or subcontractors for improvements to land are required by statute to hold back a prescribed percentage of the contract price (as of writing, 10 percent) during and after the work. The purpose is to create a fund that can satisfy any construction liens registered against the property within the lien period.

This statutory holdback is not a negotiated term — it is a legal obligation. When you are buying a property where a recent renovation or construction project was underway, your lawyer will check whether the lien period has expired and whether the statutory holdback was properly maintained. Buying a property with an undischarged construction lien can expose the buyer to significant liability. Always verify the current percentage and lien expiry rules with your lawyer, as the Construction Act has been amended in recent years.

How the Holdback Amount Is Determined

For contractual holdbacks, the amount is negotiated. Common approaches:

There is no statutory formula for contractual holdbacks. Both parties should be comfortable that the amount is sufficient to actually address the issue if the seller fails to act.

Who Holds the Money?

In Ontario residential transactions, the holdback is almost always held in the real estate lawyer's trust account — typically the buyer's lawyer's trust account, since the buyer is the one being protected. The funds are governed by Law Society of Ontario rules requiring that trust money be kept separate from office funds, held intact, and released only in accordance with the authorizing document (the holdback agreement or APS).

Conditions for Release

Release should be automatic once the agreed condition is documented. Typical evidence includes:

When both lawyers agree the condition is met, the trust funds are paid out — usually to the seller's lawyer, who then accounts to the seller.

Disputes Over Release

Holdback disputes arise when the buyer believes the work is incomplete or substandard and the seller believes they have done everything required. Because the funds are sitting in a trust account, neither side can unilaterally take them.

If the parties cannot agree, the typical options are:

  1. Negotiated settlement — lawyers exchange correspondence and the parties agree on a partial release or a reduced amount.
  2. Mediation or arbitration — faster and cheaper than court, especially if the amount is modest.
  3. Small Claims Court — for amounts up to $35,000 (as of writing; verify the current limit), Small Claims Court is accessible without a lawyer, though having one helps.
  4. Superior Court — for larger amounts or where the legal issues are complex.

The longer a holdback sits unresolved, the more it costs both parties in legal fees relative to the amount at stake. Writing a clear clause at the outset is always cheaper than litigating a vague one.

Practical Tips for Buyers Negotiating a Holdback

Frequently asked questions

Can a seller refuse to agree to a holdback clause?

Yes. A holdback clause is a negotiated term, not a legal right. The seller can refuse, in which case the buyer must decide whether to proceed on the seller's terms, walk away (if there is a valid condition in the APS), or find another solution. If the seller's refusal relates to a significant defect, that refusal itself may tell you something about the property.

What happens if the seller never completes the work and the deadline passes?

The holdback agreement should address this directly. A well-drafted clause will state that if the seller has not completed the work by the deadline, the buyer is entitled to draw on the holdback to arrange the work themselves, and any remainder is released to the seller. If the clause is silent, the parties will need to negotiate or litigate. This is why the deadline and the consequence of missing it must be spelled out.

Is a holdback clause the same as a price reduction?

No. A price reduction is permanent and unconditional — the buyer pays less, full stop. A holdback preserves the agreed purchase price but delays payment of a portion until a condition is met. If the seller completes the work, they receive the full price. A price reduction may be simpler when the parties want certainty and do not trust that the work will be done.

Does a holdback affect my mortgage financing?

It can. Some lenders will not fund against a purchase price that includes a large holdback, or they may require adjustments to the financing. Disclose the holdback clause to your mortgage broker or lender early so they can confirm it does not affect your approval or the amount advanced at closing.
