Construction Lien Lawyer Ontario: Why Early Legal Strategy Matters

Construction lien disputes are among the most time-sensitive forms of commercial litigation in Ontario. Parties searching for a Construction Lien Lawyer Ontario are often dealing with an unpaid account, a registered lien, an approaching statutory deadline, or a lien interfering with financing or a transaction. A claimant may have a substantial contractual claim yet lose statutory security if the applicable preservation or perfection deadline is missed. Conversely, an invalid, exaggerated, or improperly maintained lien can disrupt development, financing, refinancing, sale proceeds, or construction funding.

Subject to the statutory framework and exceptions, Ontario’s Construction Act gives a person who supplies services or materials to an improvement for an owner, contractor, or subcontractor a lien for the price of those services or materials. The lien generally arises when the person first supplies services or materials to the improvement. That statutory security exists alongside contractual remedies but has its own timetable, amount limits, priority rules, and enforcement requirements.

Under the current Construction Act regime, lien expiry commonly operates through 60-day periods, but the triggering event must be identified precisely. Since January 1, 2026, a notice of annual release of holdback may itself trigger a 60-day expiry period for liens relating to services or materials included in that notice. Other triggers depend on the claimant’s role and may include publication of substantial performance, completion, last supply, abandonment, termination, or certification of a subcontract as complete. Where termination is relevant, the current Act generally requires publication of a prescribed notice within seven days, and the statutory termination date for lien-expiry purposes is tied to publication of that notice.

The applicable statutory regime must therefore be identified before any deadline is calculated. Certain older improvements remain governed by the pre-July 2018 legislation, while the January 1, 2026 amendments generally apply to improvements under the newer regime subject to specific transitional rules. Applying the wrong regime can produce the wrong preservation, perfection, or holdback analysis.

Preservation is only one step. A preserved lien generally expires unless perfected within 90 days following the last day on which it could have been preserved. Where the lien attaches to the premises, perfection ordinarily requires commencement of the lien action and registration of a certificate of action, subject to the statutory framework. A perfected lien also expires immediately after the second anniversary of commencement of the action that perfected it unless, by that date, an order has been made for trial of an action in which the lien may be enforced or such an action has been set down for trial.

The statutory holdback regime can materially affect recovery and exposure. Section 22 generally requires a payer to retain a basic holdback equal to 10% of the price of services or materials supplied. Since January 1, 2026, the Act also generally requires annual release of accrued basic holdback, subject to lien rights and statutory notice and payment requirements. The annual-release process can itself affect the lien-expiry analysis.

Priority analysis is particularly important where construction financing and registered mortgages are involved. The Act contains specific priority rules governing liens, mortgages, executions, and other interests, so the outcome cannot be reduced to an ordinary first-registration analysis. Owners, contractors, lenders, purchasers, and multiple lien claimants may therefore have materially different positions in the same project.

The existence of a lien does not necessarily mean the property must remain burdened while the underlying dispute is litigated. Under section 44, a lien may in appropriate circumstances be vacated from title through payment into court or posting security. The statutory without-notice route generally requires security for the full lien amount plus the lesser of $250,000 or 25% of that amount for costs, while the court may on motion determine a reasonable amount of security in the circumstances.

Lien amounts also require discipline. Section 35 can impose liability where a person knows or ought to know that a lien has been wilfully exaggerated or that the person does not have a lien. A construction lien should therefore be tied to the statutory entitlement, the improvement, the proper parties, the amount properly lienable, and the applicable deadlines rather than used simply as collection pressure.

ME Law - Civil Litigation Law Firm

WHO WE ARE

ME Law is a litigation-focused firm representing owners, developers, contractors, subcontractors, lenders, investors, professionals, and other sophisticated parties in complex Ontario commercial disputes.

Construction lien matters extend beyond registration mechanics. We assess the contractual relationship, services or materials supplied, project chronology, payment history, invoices, certificates, notices, holdbacks, title information, financing structure, and conduct of the parties. For a claimant, the immediate objective may be preserving rights before expiry. For an owner or developer, the priority may be validity, amount, holdback exposure, or removing the lien so a financing or transaction can proceed. For lenders, priority and project exposure may be central.

Construction lien litigation is distinct from the broader merits of a construction contract dispute. Where the central issues concern delay, deficiencies, change orders, contractual performance, or damages rather than statutory lien preservation, perfection, holdback, priority, or enforcement, ME Law also acts in construction contract claims.

We approach lien files as commercial litigation mandates. The strategy should account for statutory security, contractual payment rights, available security, competing claims, settlement leverage, recovery prospects, and the client’s broader commercial objective. ME Law acts in both the prosecution and defence of construction lien claims and related proceedings.

Experienced. Effective. Results-Oriented.

Construction lien litigation should begin with chronology. At ME Law, the analysis typically follows a structured sequence:

Objective → Project → Contract → Supply → Amount Owing → Trigger Date → Preservation → Perfection → Holdback → Security → Priority → Enforcement

We first identify each party’s position in the construction pyramid because owners, contractors, subcontractors, suppliers, consultants, and lenders may have materially different statutory rights and exposure. We then reconstruct the project timeline, including first and last supply, publication of substantial performance, completion or termination events, annual holdback notices, invoices, payment certificates, and other events capable of affecting the lien timetable.

The lien amount must be analyzed separately from the gross amount asserted in the underlying dispute. Section 17 limits the value of the lien, and interest is excluded from the lien itself even where recoverable through another legal right. Set-offs, credits, deficiencies, change orders, and contractual damages may therefore require separate analysis. Where the dispute extends beyond statutory security, related Commercial Contract Lawyer Toronto and debt recovery mandates may become relevant.

We also assess holdback exposure and the practical effect of the lien on the project. Where a lien interferes with financing, sale, refinancing, or ongoing construction, posting security to vacate it from title may allow the project or transaction to continue while preserving the disputed security position.

Priority disputes require separate analysis. Construction projects may involve mortgages, advances, purchasers, multiple lien claimants, and competing creditors. The amount ultimately recoverable can depend not only on the debt but also on the statutory ranking of those interests, including priority disputes between secured and unsecured creditors where financial distress broadens the dispute.

Finally, we assess the commercial endgame. Some matters should be resolved through payment, negotiated security, or settlement. Others require enforcement proceedings, documentary or expert evidence, contractual interpretation, priority determination, or trial. The strategy should reflect the economics of the project and the value of the dispute rather than allowing procedural steps to drive the litigation.

CONSTRUCTION LIEN LAWYERS YOU CAN RELY ON

ME Law represents clients at each stage of an Ontario construction lien dispute. Where payment has stopped and a deadline may be approaching, the first task is to determine whether lien rights exist, which statutory regime applies, and what deadline follows from reliable project information. Waiting for negotiations to conclude can be dangerous if the statutory period continues to run.

For claimants, preserving a lien may protect security while payment discussions continue. Where a lien has already been preserved, the next issue is whether and when it must be perfected. The enforcement claim must then be structured around the correct defendants, statutory rights, contractual relationship, lienable amount, and available remedies.

We also represent owners, developers, contractors, lenders, and other parties responding to liens. A registered lien can have immediate commercial consequences before adjudication. The appropriate response may include demanding supporting information, challenging validity or amount, negotiating discharge, posting security, seeking a vacating order, protecting holdbacks, or defending the enforcement action.

Some disputes involve several layers of the construction pyramid at once. An owner may have paid the general contractor while subcontractors remain unpaid. A contractor may assert set-offs for deficiencies. Several claimants may compete for the same holdback. A lender may dispute priority against project funds or the property. Those matters require coordinated analysis rather than isolated treatment of each lien.

Evidence management can become decisive early. We review contracts, subcontracts, invoices, change orders, payment certificates, statutory notices, title records, and project accounting to test the lien and payment dispute. The record should identify who supplied what, when supply occurred, amounts paid, holdback remaining, and which interests may compete for the same property or fund. That chronology often determines litigation options and leverage.

Construction liens can also intersect with breach of contract, debt recovery, insolvency, receivership, and judgment enforcement. If lien litigation results in a judgment but voluntary payment does not follow, the mandate may shift into judgment enforcement and, in more complex matters, strategic enforcement in high-stakes commercial litigation involving assets, priorities, insolvency, or receivership.

Our Commitment

Our objective is to protect the client’s commercial position before statutory deadlines or project events narrow the available options. For claimants, that means identifying and preserving legitimate lien rights while positioning the underlying payment claim for resolution or enforcement. For owners, developers, contractors, lenders, and other responding parties, it means assessing validity, controlling title and financing consequences, protecting statutory holdbacks, and resolving unsupported or excessive claims efficiently.

ME Law combines construction lien analysis with broader commercial litigation strategy. If you are facing an unpaid construction account, a registered lien, an approaching lien deadline, a holdback dispute, or a lien affecting a financing or property transaction, Contact ME Law to assess the available litigation strategy.

Frequently Asked Questions

Becoming a Client

View all faqs

How do I become a client of ME Law?

Becoming a client of ME Law begins with a complimentary intake call and proceeds through a conflict check, a formal consultation with a lawyer, and, if you decide to retain the firm and ME Law agrees to act, a written Retainer Agreement. Once the agreement is executed and the required retainer is received, ME Law opens the file and begins the agreed legal work.

The first step is the initial intake call. This is a preliminary conversation with an intake specialist, not the substantive legal consultation itself. The purpose is to understand the general nature of your matter, identify the type of dispute involved, gather preliminary information, and determine whether the matter falls within ME Law’s areas of practice.

At this stage, the firm is screening the matter so that the appropriate next step can be identified. If the matter appears to be one ME Law may be able to assist with, the process moves to a conflict check before detailed legal advice is provided.

If you want to understand why that step is required, see Why is a conflict check necessary before a consultation?.

The conflict check is conducted to determine whether ME Law has a professional conflict that would prevent the firm from acting. The process is governed by the Law Society of Ontario professional obligations and is intended to protect confidentiality, independence, and loyalty. You may be asked to identify the relevant parties so that those names can be checked against the firm’s records.

Once the conflict check is cleared, the next stage is a formal consultation with a lawyer. This is different from the preliminary intake call. The consultation is the substantive meeting in which the lawyer reviews your situation in more detail, answers questions, discusses preliminary legal options and strategy, and explains what the next steps may look like.

For a fuller explanation of the meeting itself, see What is a consultation at ME Law?.

The onboarding process can therefore be understood in five stages:

Initial intake call.
ME Law gathers preliminary information, identifies the nature of the matter, and determines whether it falls within the firm’s practice areas.
Conflict check.
The relevant party names are reviewed to determine whether a conflict of interest prevents ME Law from proceeding.
Consultation with a lawyer.
Once cleared, you meet with a lawyer, either in person or remotely, for a more detailed assessment of the matter and the legal options that may be available.
Retainer and engagement.
If you decide to proceed and ME Law agrees to take on the matter, the firm provides a Retainer Agreement setting out the scope of work, estimated costs, and billing structure. The scope is defined according to the work that is actually required rather than assumed to cover every possible step in the dispute.
File opening and legal work.
Once the Retainer Agreement is executed and the required retainer is received, the file is formally opened. The lawyer can then begin the agreed work, which may include developing a case strategy, drafting pleadings, engaging in negotiations, or preparing for court proceedings, depending on the mandate.

Becoming a client is therefore not the same thing as making an inquiry or completing an intake call. It also does not occur merely because a consultation has been booked. The formal engagement stage matters because it defines what ME Law has agreed to do, how the work will be billed, and what the client and firm should expect from the relationship.

The consultation is also where the proposed scope of the engagement can be discussed. Depending on the matter, that may involve advice on a defined issue through a limited-scope retainer or broader ongoing representation through a full-scope retainer. The appropriate structure depends on the record, complexity, procedural stage, and work required.

If your matter is urgent, explain that during the intake process so the firm can assess timing and lawyer availability. See How quickly can you schedule an initial consultation? for how consultation scheduling is handled after intake and conflict clearance.

ME Law’s onboarding process is designed to move from preliminary screening to conflict clearance, substantive legal assessment, and then a clearly defined engagement. The purpose is to ensure that the firm understands the matter, can act without a professional conflict, and has agreed with you on the scope of the work before substantive representation begins.

Contact ME Law to start the intake process and discuss whether your matter is one the firm may be able to assist with.

What are the typical steps from first contact to retaining ME Law?

The process typically moves through five stages: an initial intake call, a conflict check, a consultation with a lawyer, a formal Retainer Agreement, and then file opening and the start of the agreed legal work. Each stage has a different purpose, so contacting ME Law does not automatically mean that the firm has been retained.

1. Initial intake call

The process begins with a complimentary intake call. An intake specialist gathers preliminary information about the dispute, identifies the parties involved, and considers whether the matter falls within ME Law’s areas of practice.

This is an initial screening step rather than the substantive legal consultation. If you want the broader overview of becoming a client, see How do I become a client of ME Law?.

2. Conflict check

If the matter is potentially suitable for the firm, ME Law conducts a conflict check before moving into substantive discussions. Relevant party names are checked against the firm’s records to determine whether professional obligations prevent ME Law from acting.

For more detail on the purpose of this step, see Why is a conflict check necessary before a consultation?.

3. Consultation with a lawyer

Once the conflict check is cleared, a formal consultation can be scheduled. The consultation may take place in person or remotely and is the stage at which the lawyer reviews the matter in greater depth, discusses preliminary legal options and strategy, and considers what further work may be required.

This is distinct from the initial intake call. What is a consultation at ME Law? explains the scope of that substantive meeting in more detail.

4. Retainer and engagement

If you decide to proceed and ME Law agrees to accept the mandate, the firm provides a written Retainer Agreement. It identifies the agreed scope of work, billing structure, and other terms governing the engagement.

Depending on the matter, the engagement may be structured as a limited-scope retainer for defined work or as broader ongoing representation. The lawyer-client engagement begins according to the terms of the executed retainer rather than merely because an inquiry or consultation has taken place.

5. File opening and next steps

After the Retainer Agreement is executed and any required retainer funds are received, ME Law can formally open the file and begin the work within the agreed mandate.

Depending on the dispute, that work may include developing litigation strategy, reviewing evidence, drafting pleadings, engaging in negotiations, or preparing for proceedings before the Ontario Superior Court of Justice.

The purpose of this staged process is to ensure that the matter is screened appropriately, conflicts are addressed, the legal issues are assessed, and both the client and ME Law understand the scope of the engagement before substantive representation begins.

Contact ME Law to begin the intake process.

What information do I need to provide for a conflict check after the initial call?

After the initial intake call, ME Law will ask you to identify the parties involved in your matter so the firm can complete a conflict check before receiving detailed confidential information or moving to a substantive consultation. The purpose at this stage is to establish who is involved, not to conduct a full review of your case.

The conflict check is part of ME Law’s intake and onboarding process. Before a lawyer can proceed with substantive discussions, the firm must determine whether it currently represents, previously represented, or holds confidential information relating to a party whose interests may conflict with yours.

ME Law’s conflict-check obligations arise under the Law Society of Ontario’s Rules of Professional Conduct and form part of the professional duties governing independence, loyalty, and confidentiality.

If you want a fuller explanation of the legal and ethical reason for this process, see Why is a conflict check necessary before a consultation?.

What should you provide?

At this stage, you should provide the names of the relevant parties involved in the dispute or proposed engagement. The objective is to give ME Law enough identifying information to run the appropriate check against its records.

Depending on the matter, there may be several parties whose involvement needs to be identified before the conflict check can be completed. The important point is to disclose the relevant party names accurately so the firm can determine whether a professional conflict exists.

You generally should not use the conflict-check stage to send a large volume of confidential documents or provide an extensive substantive account of the dispute before ME Law confirms that it is able to proceed. The conflict check comes before the detailed legal assessment.

The typical sequence is:

Initial intake call — ME Law gathers preliminary information about the nature of the matter.
Party identification — you provide the names required for the conflict check.
Conflict review — ME Law checks its records for potential professional conflicts.
Conflict clearance — if no conflict prevents the firm from proceeding, the matter can move to the next stage.
Consultation — detailed documents, facts, legal issues, strategy, and possible next steps can then be addressed through the substantive consultation process.

This distinction is important because completing a conflict-check form does not itself create a retainer or mean that ME Law has agreed to represent you. It is a preliminary professional safeguard within the intake process.

For the broader onboarding sequence, see How do I become a client of ME Law?. Once the conflict process is complete, What is a consultation at ME Law? explains what happens at the substantive legal assessment stage.

Contact ME Law to begin the intake process and provide the party information required for a conflict check.

What happens during the initial intake call with ME Law?

The initial intake call is a complimentary preliminary conversation with an ME Law intake specialist. Its purpose is to understand the general nature of your matter, gather the information needed to assess whether it falls within the firm’s areas of practice, identify the relevant parties, and determine the appropriate next step.

The intake call is different from a substantive consultation with a lawyer. At this stage, ME Law is not conducting a detailed review of your evidence or providing a full legal assessment. Instead, the firm is gathering enough preliminary information to determine whether the matter is one it may be able to assist with and what must happen before a consultation can proceed.

For an overview of the complete onboarding process, see How do I become a client of ME Law?.

During the initial intake process, you may be asked to explain:

the general nature of the dispute;
who the relevant parties are;
whether litigation or another legal proceeding has already started;
whether there are immediate deadlines or urgent circumstances;
what type of assistance you are seeking from ME Law.

Identifying the parties is particularly important because the next step will ordinarily involve a conflict check under the Law Society of Ontario’s professional-conduct requirements. ME Law must determine whether a professional conflict prevents the firm from proceeding before receiving detailed confidential information or moving into substantive legal discussions.

For the practical information required at that stage, see What information do I need to provide for a conflict check after the initial call?.

Once the conflict check is completed and the firm is able to proceed, a formal consultation with a lawyer can be scheduled. That consultation is where the matter can be examined in greater depth, including the factual record, legal issues, preliminary strategy, and possible next steps.

The distinction matters: an intake call, a conflict check, a substantive legal consultation, and a Retainer Agreement are separate stages of the client-onboarding process. Completing the intake call does not by itself mean that ME Law has agreed to act or that a lawyer-client retainer has been established.

If you want to know how quickly the substantive lawyer meeting can be arranged after intake and conflict clearance, see How quickly can you schedule an initial consultation?.

Contact ME Law to begin the intake process.
