Discharging or Vacating a Construction Lien in Ontario

A construction lien, once registered against title under Ontario’s Construction Act, 2019, becomes a cloud on the property’s title. It does not need to be proven valid to have this effect — the registration itself is usually enough to concern a buyer’s lawyer, a lender, or a title insurer, since it represents a claim that could, in theory, be enforced against the property. For background on how a lien gets registered in the first place, see our guide to construction liens in Ontario.

For an owner, this generally creates a practical problem that is separate from the underlying dispute about whether money is actually owed: a sale cannot close, and a refinancing cannot proceed, with an unresolved lien sitting on title. This is why owners facing a time-sensitive transaction often focus first on getting the lien off title, through one of several available routes, rather than on resolving the broader dispute about who owes what.

It is worth separating these two problems clearly in your own mind, because they often get resolved on different timelines. Clearing title can happen relatively quickly through one of the routes below, while the underlying question of how much, if anything, is actually owed to the lien claimant can take much longer to work out, whether through negotiation, adjudication, or litigation. Treating the two as the same problem tends to slow everyone down unnecessarily.

The most direct way to deal with a lien is simply to pay the amount claimed (or an amount the claimant agrees to accept) in exchange for the claimant discharging the lien from title. This is straightforward when the amount owing is not seriously disputed, or when the cost and disruption of leaving the lien in place outweighs the amount at stake.

The obvious downside is that it means paying money the owner may genuinely believe is not owed, purely to clear title. For that reason, outright payment tends to be the preferred route mainly where the dispute is minor relative to the transaction at stake, or where the owner is confident the amount is legitimately owing in any event.

In some situations, rather than paying the full claimed amount, the owner and the lien claimant negotiate an arrangement involving the project’s existing holdback — generally 10% of the contract price withheld under the Construction Act — as the pool of funds the dispute is actually about. For more on how holdback is generally calculated and released, see our guide to holdback requirements in Ontario.

This option tends to work best where the lien amount is modest relative to the overall project and the parties can agree, even informally, on a way to set aside or earmark funds to cover the disputed amount while the lien is discharged and the broader relationship between owner and contractor continues. It is generally a negotiated solution rather than a formal legal process in its own right.

Because this route depends on cooperation between the owner and the claimant, it tends to work less well once the relationship has broken down entirely or where there is deep disagreement about the quality or value of the work performed. In those situations, one of the more formal routes — paying out the claim or posting security with the court — is often the more realistic path forward.

The Construction Act specifically allows an interested party — typically the owner, but sometimes a mortgagee or the contractor — to apply to the court to vacate a lien from title by posting security, generally cash paid into court or a lien bond, in an amount equal to the lien plus an allowance for costs set by the Act and court rules. Once the court grants the order, the lien is removed from title, and the security takes its place as the subject of the ongoing dispute.

This option is particularly useful when a sale or refinancing is time-sensitive and the parties are not close to a negotiated resolution. It allows the property to move forward — the sale or refinancing can close — while the actual question of whether the claimant is owed money, and how much, continues to be worked out through litigation or, on an eligible contract, through adjudication under the Act. See our overview of construction adjudication in Ontario for how that faster dispute process can sometimes apply.

Posting security generally requires a court application, so there is some lead time involved, and owners facing an approaching closing date are usually well served by starting this process early rather than at the last moment.

The security posted to vacate a lien is sometimes cash paid into court, and sometimes a lien bond obtained from a surety company, which can be a more capital-efficient option for an owner who does not want to tie up cash during an active transaction. Either form of security is generally meant to give the lien claimant the same practical protection it had against the property, just moved from the title itself to a defined fund or instrument.

The Construction Act builds firm timelines into the lien process specifically so that liens cannot sit indefinitely on title. A lien generally must be preserved — registered on title or, for some holdback-only claims, served — within 60 days of a defined triggering event, such as substantial performance of the contract, completion, or abandonment. After preservation, the claimant generally has a further 90 days to perfect the lien, meaning a court action must be started and the claim registered against the action.

If a lien claimant lets either deadline pass — failing to preserve the lien in time, or preserving it but never perfecting it — the lien generally expires on its own. This means that, in some cases, an owner facing a registered lien may find the most straightforward path is simply confirming the applicable deadlines and monitoring whether the claimant takes the required next step, rather than immediately pursuing one of the more active options above.

That said, relying on the deadlines alone is a reasonable strategy mainly when there is no urgent need to clear title. An owner mid-sale or mid-refinancing generally cannot afford to simply wait out a 90-day perfection window, since most transactions move much faster than that, which is why posting security or negotiating a resolution tends to be the more practical choice whenever a transaction is already in motion.

Which option makes sense in a given situation generally depends on how much time pressure the owner is under, how confident each side is in the underlying dispute, and the size of the lien relative to the transaction at stake. An owner with no imminent sale or refinancing may be content to let the statutory deadlines run their course, while an owner mid-transaction often needs to act quickly, making posting security the more practical route regardless of the dispute’s merits.
