Lien Waiver and Release (Canada)

A Canadian Lien Waiver and Release is a legal document used in the construction industry by which a contractor, subcontractor, material supplier, or other construction participant waives and releases their construction lien rights against a property in exchange for payment in Canada. Construction lien waivers are an essential part of the payment process in Canadian construction projects, providing property owners, general contractors, and lenders with assurance that lien rights have been released and the property title will not be encumbered by construction liens.

In Canada, construction lien rights are governed by provincial legislation that varies across the country. Ontario's Construction Act (R.S.O. 1990, c. C.30, as amended by Bill 142 in 2018) governs construction liens in Ontario. British Columbia uses the Builders Lien Act (S.B.C. 1997, c. 45), while Alberta has the Builders' Lien Act (R.S.A. 2000, c. B-7). Each province has its own terminology, deadlines, and procedural requirements. A lien waiver must be drafted with awareness of the applicable provincial legislation to confirm it is effective and enforceable.

The lien waiver can be either conditional or unconditional. A conditional lien waiver becomes effective only upon the actual receipt and clearance of the specified payment. If the cheque bounces or the electronic transfer fails, the waiver is void and the claimant's lien rights are fully preserved. An unconditional lien waiver is effective immediately upon execution, regardless of whether payment has actually been received. Canadian construction professionals should strongly prefer conditional waivers to protect their lien rights until payment is confirmed.

The waiver can also be categorized by scope: a progress payment waiver covers a specific payment period and releases lien rights only for the work performed through a specified date, while a final payment waiver covers all remaining work and releases all lien rights upon final payment. Progress payment waivers are exchanged with each progress draw throughout the project, while the final waiver is exchanged at project completion.

A critical consideration in Canadian construction law is the statutory holdback. Most provinces require the property owner to retain 10% of each progress payment as a holdback fund to protect unpaid subcontractors and suppliers. A progress payment lien waiver should not release the owner's obligation to maintain the statutory holdback. The holdback can only be released after the applicable lien period has expired (60 days in Ontario, 55 days in BC, 45 days in Alberta) and no liens have been preserved against the property.

The provincial framework governing lien waivers varies significantly. In Ontario, the Construction Act (R.S.O. 1990, c. C.30) as amended by the Prompt Payment and Construction Lien Act 2019 (S.O. 2019, c. 10) introduced mandatory prompt payment provisions under Part I.1 and adjudication under Part II.1. Section 31 of the Ontario Construction Act governs the preservation of liens by registration at the Land Registry Office. The Ontario Builder's Lien Fund under Section 22 creates trust obligations that survive lien waivers unless explicitly released. In British Columbia, Section 22 of the Builders Lien Act (S.B.C. 1997, c. 45) governs holdback obligations, and Section 8 governs the attachment of liens. The BC Land Title Office maintains the registry for lien registrations. In Alberta, the Builders' Lien Act (R.S.A. 2000, c. B-7) Section 18 establishes the holdback requirements, and Section 7 governs the attachment of builders liens to the owner's estate or interest in the land. The Alberta Land Titles Office processes lien registrations under the Land Titles Act (R.S.A. 2000, c. L-4). In Manitoba, the Builders' Liens Act (C.C.S.M. c. B91) and in Saskatchewan, the Builders' Lien Act (S.S. 1984-85-86, c. B-7.1) contain comparable provisions. For disputed lien amounts, Ontario's Construction Act provides for mandatory adjudication through Authorized Nominating Authorities designated by the Ontario Ministry of the Attorney General. The Dispute Adjudication Rules under Ontario Regulation 306/18 govern the adjudication process.

A Canadian Lien Waiver and Release is needed at multiple stages throughout a construction project as part of the payment process. The most common scenario is the exchange of a lien waiver for a progress payment. When a contractor submits a progress invoice or payment application, the property owner or general contractor may require a lien waiver from the previous payment period before releasing the current payment. This practice confirms that lien rights are progressively waived as payments are made, reducing the risk of liens being filed against the property.

Property owners need lien waivers from the general contractor with each progress payment to confirm that the contractor is not accumulating unpaid lien rights against the property. The owner should also require the general contractor to obtain lien waivers from all subcontractors and material suppliers before releasing each progress payment. Under Ontario's Construction Act, the owner has a statutory obligation to retain a 10% holdback from each payment, and obtaining lien waivers helps manage the risk associated with construction projects.

General contractors need lien waivers from subcontractors before making progress payments. The general contractor should obtain waivers from all subcontractors, material suppliers, and equipment rental companies who have supplied labour, materials, or equipment to the project. This protects the general contractor from claims by subcontractors who may assert that they have not been paid, and provides documentation to the property owner that the payment chain is functioning properly.

Mortgage lenders and construction financiers typically require lien waivers before advancing construction loan funds. When the borrower draws on a construction mortgage, the lender will require evidence that all previous payments have been accounted for and that no lien claims are outstanding. This protects the lender's security interest in the property, as construction liens generally have priority over mortgages registered after the commencement of the improvement in most provinces.

Title insurers may require lien waivers before issuing or extending title insurance coverage for properties that have recently undergone construction or renovation work. The title insurer needs assurance that no construction liens will be filed against the property that could affect the insured title.

At project completion, a final lien waiver is needed from all construction participants before the owner releases the final payment and the statutory holdback. The final waiver confirms that all work has been completed, all payments have been received, and all lien rights are released. In Ontario, the holdback can be released after 60 days from the date of substantial completion or the last supply, provided no liens have been preserved. In BC, the holdback period is 55 days, and in Alberta, it is 45 days.

A thorough Canadian Lien Waiver and Release must contain several essential elements to be legally effective and properly protect all parties involved. The document must specify the waiver type (conditional or unconditional) and the waiver scope (progress payment or final payment). A conditional waiver is effective only upon receipt of payment, while an unconditional waiver is effective immediately. A progress payment waiver covers work through a specific date, while a final payment waiver covers all remaining work and releases all lien rights.

The claimant (the party waiving lien rights) must be identified with their full legal name or registered business name, business address, phone number, and role on the project (general contractor, subcontractor, material supplier, equipment rental company, or labourer). The property owner must be identified with their full legal name and mailing address. The project must be described with the property address, project name (if applicable), and a description of the work performed or materials supplied.

The payment information must be clearly stated in Canadian dollars (CAD), including the payment amount being made or acknowledged, the date through which the waiver covers work performed (the "Through Date"), and the date the waiver is executed. These details define the precise scope of the waiver and confirm that future work and payments are not inadvertently covered.

The statutory holdback acknowledgment is a critical element unique to Canadian construction law. The waiver should explicitly acknowledge that the owner is required to retain a statutory holdback (typically 10%) under provincial construction lien legislation, and that the waiver does not release the owner's obligation to maintain the holdback for the prescribed lien period. In Ontario, the holdback must be maintained for 60 days under the Construction Act. In BC, the period is 55 days under the Builders Lien Act. In Alberta, the period is 45 days under the Builders' Lien Act.

The exceptions and reservations clause allows the claimant to exclude specific items from the waiver, such as disputed change orders, pending claims under Section 14 of Ontario's Construction Act, or retainage amounts. Under Section 6.6 of the Ontario Construction Act, a proper notice of non-payment must be delivered within 14 days of receiving a proper invoice where payment is disputed. The claimant should not waive rights to amounts subject to an active adjudication under Section 13.5 of the Construction Act or a pending lien under Section 31. The waiver should clearly list each exception by contract number, change order number, and dollar amount.

The waiver and release clause must reference the applicable provincial construction lien legislation: Section 14 and Section 31 of the Ontario Construction Act; Section 8 and Section 31 of BC's Builders Lien Act; Section 7 and Section 23 of Alberta's Builders' Lien Act. The clause should also address trust claim rights under Section 7 of the Ontario Construction Act and Section 10 of BC's Builders Lien Act, which impose statutory trust obligations on monies received by the contractor from the owner. A warranty that the claimant has paid all labourers and subcontractors from the payment received is essential to satisfy the trust obligations under Section 7.

The governing law clause must specify the province. The representations and warranties section should confirm the claimant holds valid corporate authority under Section 2 of the applicable provincial Business Corporations Act, has not assigned lien rights under Section 38 of the Ontario Construction Act, and no other party holds claims through the claimant for the scope of work covered by the waiver.

Optional elements include a Commissioner for Oaths or Notary Public sworn declaration, which adds credibility and may be required by the owner, lender, or title insurer. Confidentiality and indemnification clauses may also be included depending on the parties' requirements.

Prompt payment compliance is an important consideration when drafting lien waivers in Ontario. Part I.1 of the Construction Act (added by S.O. 2019, c. 10, Schedule 1) requires owners to pay proper invoices within 28 days under Section 6.4, and contractors to pay subcontractors within 7 days of receiving payment under Section 6.5. Where a party disputes a payment, a notice of non-payment must be issued within 14 days under Section 6.6. The adjudication process under Part II.1 and Ontario Regulation 306/18 provides a rapid dispute resolution mechanism for payment disputes. A lien waiver obtained through coercion or as a condition of receiving payment that is legally owed may be unenforceable under Section 13 of the Construction Act, which voids any agreement that purports to waive lien rights before the claimant has actually received payment for the work covered.
