Canadian prompt payment and construction law reforms

How recent developments are impacting the Canadian construction & infrastructure sector

Updated on: November 3, 2021

Construction Legislation


Prompt payment and mandatory adjudication legislation is being enacted across Canada in an effort to alleviate perceived payment delays down the construction pyramid. We have provided a brief overview covering the developments in each jurisdiction which we will continue to update with the latest news and useful insight, so check back regularly.  

  • In Ontario, the changes to the Construction Act (formerly the Construction Lien Act) introducing prompt payment and adjudication came into force on October 1, 2019. The prompt payment regime comprises swift payment deadlines, requiring the owner either to pay within 28 calendar days or dispute within 14 calendar days, describing the reasons for non-payment. In turn, the contractor must either pay its subcontractors within seven calendar days of receipt of payment or send notices of dispute within seven calendar days, as described in our previous Update. Introduced by the Construction Act, adjudication is a quick interim method to resolve disputes on a construction project. An adjudication must begin prior to completion of the contract or subcontract, unless the parties agree otherwise. The adjudication regime in Ontario is being administered and overseen by the Ontario Dispute Adjudication for Construction Contracts (ODACC), which has released its second Annual Report, as discussed in our previous blog post. Ontario is the first jurisdiction with a prompt payment and adjudication regime layered on top of an existing construction lien regime. While the interactions between this regime and liens have been considered, to a large degree, our team continues to uncover additional issues in practice and devise contractual solutions for our clients.
  • In Nova Scotia, the Builders’ Lien Act (amended) received royal assent on April 12, 2019, but is yet to come into force. Once in force, the current lien legislation will be renamed Builders’ Lien and Prompt Payment Act. Although the amendments introduce concepts from Ontario’s new prompt payment regime, it takes a narrower approach as regards availability of adjudication as it limits the availability of adjudication to disputes that are the “subject of a notice of non-payment.” Unless exempted by the regulations, the amendments are applicable to contracts and subcontracts made after the date of enactment. Our team is monitoring the progress, as we await regulations prescribing application of the amendment, payment timelines, adjudication procedures and details regarding notice of non-payment.
  • In SaskatchewanThe Builders’ Lien (Prompt Payment) Amendment Act, 2019 (Amendment Act) is scheduled to be proclaimed into force on March 1, 2022. On August 20, 2020The Builders’ Lien Amendment Regulations, 2020 (SR 92/2020) was filed to amend the existing regulations. The amendment regulations elaborate on the prompt payment and adjudication regime and will come into force on the same day as the Amendment Act. The Saskatchewan Construction Dispute Resolution Office (“SCDRO”), a new not-for-profit corporation, will act as the official adjudication authority and the ADR Institute of Saskatchewan Inc. will work with the SCDRO to provide adjudicators. Note that the prompt payment and adjudication regime will not apply to architects, engineers, land surveyors and persons providing services or materials for any improvement with respect to a mine or mineral resource (including any activities respecting exploration, development, production, decommissioning or reclamation) or an improvement related to infrastructure in connection with the generation, transmission or distribution of electrical energy.
  • In AlbertaBill 37 titled Builders’ Lien (Prompt Payment) Amendment Act, 2020 received royal assent on December 9, 2020, but is yet to come into force. Bill 37 focuses on major reforms to the Builders’ Lien Act (the Act) which include the introduction of prompt payment requirements, a new dispute resolution mechanism known as adjudication, an extension of lien registration periods, and renaming the Act as the Prompt Payment and Construction Lien Act. Unlike Ontario-style prompt payment, subject to the regulations, monthly billings are mandated through proper invoices issued at least every 31 days unless any contractual requirements for testing and commissioning are not met. Bill 37 also makes major lien fund and minor lien fund payments to the contractor mandatory if certain conditions are met, as detailed in our previous Update. In June 2021, Bill 62 titled Red Tape Reduction Implementation Act, 2021 received royal assent. Bill 62 further amends the Act to provide greater clarity regarding when the Act will apply, permit the electronic submission of certificates of substantial performance, create additional exceptions to the final and binding nature of adjudication, and establish additional bars to the use of adjudication.
  • In British Columbia, in July 2020, the British Columbia Law Institute published a Report on The Builders Lien Act [PDF] which offers 86 recommendations to simplify the Builders Lien Act and clarify the meaning of the more problematic provisions. According to the Report, prompt payment and adjudication pertain to general financial management of construction projects, whereas the lien legislation is concerned with security of payment. Hence, the Report does not address the merits of prompt payment or adjudication legislation.
  • In Manitoba, on November 19, 2018, the Manitoba Law Reform Commission released its final report titled The Builders’ Liens Act of Manitoba: A Modernized Approach [PDF], which recommends significant reforms to the existing lien legislation, including introduction of prompt payment and adjudication. In order to reflect changes to the legislation, the Report recommends renaming the legislation as The Construction Contract Remedies Act.
  • In New Brunswick, Law Reform Notes #42 [PDF] (July 2019) and #43 (April 2020), published by the Office of the Attorney General recommends that the reform of the Mechanics’ Lien Act and the introduction of prompt payment and adjudication in two phases. As a part of the first phase, the Construction Remedies Act (Act) and the General Regulation came into force on November 1, 2021. The Act repeals and modernizes the existing lien legislation by amending lien, holdback, trust, substantial performance and security bond provisions. As for the second phase, Law Reform Note #42 discusses stakeholder concerns regarding introduction of adjudication in a smaller jurisdiction like New Brunswick. Given the difficulty in finding adjudicators, the province is considering the possibility of co-operation with other jurisdictions and the option of referring claims under $20,000 to Small Claims Court.
  • In QuébecAn Act to facilitate oversight of public bodies’ contracts and to establish the Autorité des marchés publics, which received royal assent on December 1, 2017,  amended the Act respecting contracting by public bodies and allowed the Conseil du trésor to implement pilot projects to facilitate payments to enterprises which are parties to certain public contracts and subcontracts. In 2018, the Chair of the Conseil du trésor, by order, authorized the implementation of the Pilot project to facilitate payment to enterprises that are parties to public construction work contracts and related public subcontracts (Pilot Project). The Pilot Project prescribes the use of payment calendars and introduces dispute settlement by adjudicators. A public body whose contract is subject to the Pilot Project is required to state as such in the call for tenders. Initially, approximately fifty public construction projects were subject to the Pilot Project, which was established for a three-year term. Subsequently, An Act respecting the acceleration of certain infrastructure projects, extended the application of the Pilot Project to over 180 listed public infrastructures, “unless the manner in which the relevant contract or subcontract is to be carried out does not allow for the application of a monthly payment schedule”. Additionally, it provided that the terms and conditions prescribed in the Pilot Project “are applicable to a contract or subcontract until the infrastructure project from which it arises ends, provided the contract was entered into no later than 11 December 2024”.

At the federal level, the Federal Prompt Payment for Construction Work Act, which addresses the non-payment of contractors and subcontractors performing construction work for federal construction projects, was passed as part of a larger budget bill on June 21, 2019.  However, it is not yet in effect. Once in force, it surprisingly will not grandfather existing contracts; instead, it will provide for a one-year deferral period before it applies to existing contracts. At that point, it may be imagined that the sudden application mid-performance of the new law to existing contracts drafted before the Act came into effect may be quite disruptive to those contracts. The federal government may choose to exempt federal projects from the federal regime either individually or on a province-wide basis in cases where a reasonably similar provincial legislation has been adopted. We have discussed the federal prompt payment landscape in further detail in our previous Update.

Update on BILL S-224 – Federal prompt payment legislation

Osler, Hoskin & Harcourt LLP – January 17, 2018

Bill S-224, which would implement federal prompt payment for the construction industry, was introduced in the Senate in April 2016 and passed third reading in early May, 2017. Notwithstanding this early progress, the Bill appears to have stalled between the Senate and the House of Commons, and it has not yet been introduced in the House seven months after Senate approval.

Senator Don Plett, who introduced Bill S-224 in the Senate, has expressed open frustration with the lack of progress and attributes it to politics at the expense of trade contractors. In October and November 2017, Senator Plett wrote open letters to MP Judy Sgro, asking that she advance the Bill in the House of Commons or remove herself as sponsor so that the Bill can be advanced by another MP.

By way of comparison, those Senate Bills currently before the House that have received first reading typically made the transition within two weeks (S-2, S-5, S-28, S-228 and S-232). In contrast, other Senate Bills that are still awaiting first reading in the House include those that passed in the Senate in 2015 and 2016 (S-205, S-215 and S-225). Caution must be exercised in drawing conclusions, but it does appear that federal prompt payment legislation is coming slowly, if it is coming at all in its current form.
