Ontario Construction Act — adjudication, prompt payment, liens; and the two nuclear programmes named in docs/01

Committed under AGENTS.md R14 and the CLAUDE.md rule it encodes: anything a spec makes a claim about must be reachable from the repository. Every fact the six /practice/* pages state about the world is checkable here or it is not published.

Retrieved 2026-08-29. Fetched from the primary sources listed below and extracted with quotations pasted verbatim. This file is the artefact; the pages cite it. Do not paraphrase a fact into a page that is not stated here.

R18 re-check — cutover pass, 2026-09-01

⚠️ THIS FILE CARRIES THE STANDING RE-CHECK INSTRUCTION ABOVE AND WAS NOT ONE OF R18's SEVEN LIMBS, AND IT WENT UNSTAMPED IN THE FIRST PASS. Five of seven extracts were stamped and two were not, so a reader could not tell whether this one was considered and found non-volatile or simply missed. Found by adversarial-reviewer, 2026-09-02 — the same control-fires-over-part-of-its-scope defect as R18 having no checklist item, one notch smaller. Nothing here was re-retrieved.

• No R18 limb, but ONE CANDIDATE LIMB, and it is flagged rather than silently adopted. /practice/construction/ publishes: "Ontario Power Generation … applied in March 2026 for a licence to operate it." That is a pending application, so it moves the way limb (a) moves. It is not false today — the application was made, and a completed past act stays true — which is why this is a note and not a blocker. But a reader takes it as current status, and unlike limb (a) the sentence is not time-anchored ("when this page was written"). For Pouya at the next re-check: adopt it as R18 limb (h), or time-anchor the sentence and drop it.
• The rest is stable: Part II.1 in force since 2019-10-01, and ODACC's own statement that it is the Authorized Nominating Authority. The ODACC 2025 Annual Report is cited for institutional facts rather than for figures, so it does not carry limb (d)'s exposure [verified 2026-09-02 — swept dist/practice/construction/index.html].

Ontario Dispute Adjudication for Construction Contracts (“ODACC”) is the Authorized Nominating Authority (“ANA”) under the Construction Act. As the ANA, ODACC is responsible for administering construction-related adjudications and for training and qualifying Adjudicators. ODACC derives its powers from the Construction Act and Ontario Regulation 264/25

Adjudication and prompt payment provisions of the Construction Act came into force on October 1, 2019. Further amendments to the Construction Act came into force on January 1, 2026. ODACC is responsible for administering adjudications and for training and certifying adjudicators.

Only Adjudicators listed in the Adjudicator Registry are permitted to conduct adjudications and make Determinations under the Construction Act.

The adjudication process commences when the Claimant provides the Respondent with a Notice of Adjudication (and sends ODACC an electronic copy).

Ontario Dispute Adjudication for Construction Contracts (“ODACC”) is the Authorized Nominating Authority (“ANA”) under the Construction Act. As the ANA, ODACC is responsible for administering construction-related adjudications and for training and qualifying Adjudicators.

Further duties and powers of ODACC are listed in sections 6 through 18 of Ontario Regulation 264/25.

ODACC — Adjudication Process

https://odacc.ca/en/adjudication-process/ — retrieved 2026-08-29

Adjudication is a dispute resolution process that allows Parties to present their dispute to an independent third party for a decision.

The Adjudicator will consider the evidence and make a decision (a “Determination”) within thirty days of the Claimant submitting its supporting documents. If the Adjudicator orders a Party to pay the other Party, the payment must be made within fifteen days of the issuing of the Determination.

Adjudications are quick. After an Adjudicator receives the Claimant’s documents, the Adjudicator must render a Determination no later than 30 days after receiving the Claimant’s documents (unless the Determination due date is extended);

Determinations are binding only until a decision is made in a subsequent proceeding. Either Party can commence a proceeding in court or through arbitration. The Determination is binding until a final decision is made in the subsequent proceeding;

Adjudication is available as a right. A Party to a construction contract can commence an adjudication without the other Party’s consent

An adjudication may only be conducted by a certified ODACC Adjudicator.

The Darlington New Nuclear Project is leading the way in the advancement of Small Modular Reactor (SMR) technology in Canada – the future of nuclear power generation.

On July 7, 2023, the Ontario government announced it will work with Ontario Power Generation (OPG) to commence planning and licensing for three additional SMRs, for a total of four SMRs at the Darlington new nuclear site.

In March 2026, OPG applied to the Canadian Nuclear Safety Commission (CNSC) for a Licence to Operate (LTO) the first SMR. The LTO is the regulatory approval required to complete commissioning and safely operate the reactor, once construction is complete.

OPG’s application for this licence is comprised of a number of packages, submitted to the CNSC over the course of several months. This application process will culminate in a public hearing where the regulator will hear comments from members of the public regarding our application.

Site construction progress - Summer 2026

The construction of the reactor building is now progressing upwards towards grade following the successful basemat (the foundation of the Unit 1 reactor building) installation earlier this year.

Additional regulatory approvals will be required prior to construction and operation of additional units.

Our planning goal is to complete construction of the first SMR by the end of this decade, and connect to the grid by the end of 2030.

The site is owned by Ontario Power Generation (OPG).

The BWRX-300 is a 300 MWe water-cooled, natural circulation small modular reactor.

OPG applied for a licence to construct 1 BWRX-300 reactor in October 2022 and was granted the licence in April 2025.

In March 2026, OPG applied for a 20-year licence to operate 1 BWRX-300 reactor and an associated low- and intermediate-level waste storage structure.

Current status: 1 unit under construction

The CNSC has verified that the commitments for RHP-1 (for installation of the reactor building foundation) were met, and the hold point was removed on March 30, 2026.

As Ontario prepares for the future through its Integrated Energy Plan, Bruce Power has initiated a federal Impact Assessment (IA) for the Bruce C Project. The project aims to create an option to build up to 4,800 megawatts of nuclear capacity at the Bruce Power site, located within the Territory of the Saugeen Ojibway Nation, in the Municipality of Kincardine, Ontario.

Bruce Power is advancing the IA process in a proactive, open and transparent manner to engage Indigenous Peoples, local communities, interested parties and the public early on.

The Bruce C Project is creating the option to build up to 4,800 MW of nuclear capacity on the existing Bruce Power site.

Through the federal integrated Impact Assessment (IA) process led by the Impact Assessment Agency of Canada (IAAC) alongside the Canadian Nuclear Safety Commission (CNSC), Bruce Power is studying the potential environmental, economic, social and health impacts of a new nuclear build.

IN PROGRESS — In the Impact Statement phase, the Bruce C Project team will prepare the Impact Statement

UPCOMING — In the Impact Assessment Phase phase, the Review Panel will prepare hearing materials and public hearings will be held.

COMPLETED — During the Planning phase, the Bruce C Project team: Engaged with Indigenous Nations and Communities, local municipalities and the public on project information.

At the completion of the Planning Phase, Bruce Power received the Integrated Tailored Impact Statement Guidelines and Planning Phase documents from the IAAC and CNSC, which defines the requirements for Bruce Power to include in the Impact Statement and Licence to Prepare Site Application.

Reactor technology has not been selected at this time, and the Impact Assessment for the Bruce C Project will be technology neutral. This approach considers multiple technologies to provide optionality to the province in long-term electricity system planning.

Bruce Power has commenced a siting assessment to understand potential constraints and opportunities on the Bruce Power site, support conceptual layout development, and evaluate suitable areas for potential development.

Planning phase of Integrated Impact Assessment completed for Bruce Power's potential Bruce C project — Bruce Power newsroom, dated 2025-08-21 (proponent's own release)

https://www.brucepower.com/2025/08/21/planning-phase-of-integrated-impact-assessment-completed-for-bruce-powers-potential-bruce-c-project/ — retrieved 2026-08-29

The planning phase of the federal Integrated Impact Assessment process has been completed for Bruce Power’s Bruce C project.

On August 19, the Impact Assessment Agency of Canada (IAAC), in collaboration with the Canadian Nuclear Safety Commission (CNSC), issued the formal Notice of Commencement of Impact Assessment under the Impact Assessment Act. This notice initiates the next stage of the process, the development of the Impact Statement, and is accompanied by Tailored Impact Statement Guidelines (TISG) and documents that will shape the scope and depth of the assessment moving forward.

The planning phase is the first of the five phases in Impact Assessment process.

What this establishes

Each item names the source it rests on. An item here that no quotation above supports is a defect in this file, not a fact.

• The statute's current name and citation is the Construction Act, R.S.O. 1990, c. C.30. The e-Laws consolidation retrieved on 2026-08-29 states 'Consolidation Period: From January 1, 2026 to the e-Laws currency date' and 'Last amendment: 2025, c. 14, Sched. 2.' Source: https://www.ontario.ca/laws/statute/90c30
• The Construction Act did not replace the Construction Lien Act with a new statute — it IS the same statute renamed. Section 1 of the Construction Lien Amendment Act, 2017, S.O. 2017, c. 24 (assented to December 12, 2017) reads: '1 The short title of the Construction Lien Act is repealed and the following substituted: Construction Act'. The chapter number is unchanged (R.S.O. 1990, c. C.30) across the rename. Source: https://www.ontario.ca/laws/statute/S17024
• The rename took effect on 1 July 2018. e-Laws' own version list for R.S.O. 1990, c. C.30 shows version 8 titled 'Construction Lien Act, R.S.O. 1990, c. C.30' running to 2018-06-30, and version 9 titled 'Construction Act, R.S.O. 1990, c. C.30' beginning 2018-07-01. Source: https://www.ontario.ca/laws/api/v2/legislation/en/act-versions/statute/90c30
• The historical e-Laws consolidation at /laws/statute/90c30/v8 carries the short title 'Construction Lien Act' and the chapter 'R.S.O. 1990, Chapter C.30'; the next consolidation, /laws/statute/90c30/v9, carries the short title 'Construction Act' and the same chapter. Source: https://www.ontario.ca/laws/statute/90c30/v9
• LIEN PRESERVATION — the deadline is set by s. 31 (headed 'Expiry of liens'), read with s. 34 ('A lien may be preserved during the supplying of services or materials or at any time before it expires'). Under s. 31(2) a contractor's lien 'expires at the conclusion of the 60-day period next following' publication of the certificate/declaration of substantial performance or, where earlier, completion, abandonment or termination of the contract; where there is no certification or declaration, the 60-day period runs from the earlier of completion and abandonment or termination. Section 31(3) applies the same 60-day period to the lien of 'any other person' (running from the earliest of publication, last supply, completion/abandonment/termination, or certification of the subcontract as complete under s. 33). Section 31(2.1) applies the same 60-day period to a workers' trust fund lien. Source: https://www.ontario.ca/laws/statute/90c30
• HOW A LIEN IS PRESERVED — s. 34(1): where the lien attaches to the premises, 'by the registration in the proper land registry office of a claim for lien on the title of the premises'; where it does not attach, 'by giving to the owner a copy of the claim for lien.' Source: https://www.ontario.ca/laws/statute/90c30
• LIEN PERFECTION — s. 36(1): 'A lien may not be perfected unless it is preserved.' Section 36(2): 'A lien that has been preserved expires unless it is perfected prior to the end of the 90-day period next following the last day, under section 31, on which the lien could have been preserved.' Section 36(3) defines perfection as commencing an action to enforce the lien and (where the lien attaches to the premises) registering a certificate of action on title. Source: https://www.ontario.ca/laws/statute/90c30
• A perfected lien has a further limit: s. 37(1) provides that it 'expires immediately after the second anniversary of the commencement of the action that perfected the lien' unless an order is made for the trial of an action in which the lien may be enforced, or such an action is set down for trial, on or before that anniversary. Source: https://www.ontario.ca/laws/statute/90c30
• As of the 1 January 2026 consolidation, s. 31(6) (added by 2025, c. 14, Sched. 2, s. 6) requires that 'No later than seven days after a contract is terminated, either the owner or the contractor or other person whose lien is subject to expiry shall publish a notice of the termination in the prescribed form and manner', and s. 31(7) fixes the publication date as the termination date for the purposes of s. 31. Source: https://www.ontario.ca/laws/statute/90c30
• INTERIM ADJUDICATION — Ontario does have statutory construction adjudication. It sits in Part II.1 of the Construction Act, headed 'CONSTRUCTION DISPUTE INTERIM ADJUDICATION' (ss. 13.1–13.23). Section 13.1 defines 'adjudication' as 'construction dispute interim adjudication under this Part'. Source: https://www.ontario.ca/laws/statute/90c30
• Section 13.2(1) provides that 'The Minister may designate an entity to act as Authorized Nominating Authority for the purposes of this Part', and s. 13.1 defines 'Authority' as 'the Authorized Nominating Authority designated under section 13.2'. The Act itself does not name the designated entity. Source: https://www.ontario.ca/laws/statute/90c30
• The Authorized Nominating Authority is Ontario Dispute Adjudication for Construction Contracts (ODACC). ODACC states on its own site: 'Ontario Dispute Adjudication for Construction Contracts ("ODACC") is the Authorized Nominating Authority ("ANA") under the Construction Act. As the ANA, ODACC is responsible for administering construction-related adjudications and for training and qualifying Adjudicators.' Source: https://odacc.ca/en/aboutus/
• ODACC repeats the same statement in its own 2025 Annual Report (the report it is required to publish as ANA), which describes the fiscal year 1 August 2024 to 31 July 2025 as 'the sixth year of its operation'. Source: https://odacc.ca/wp-content/uploads/2021/07/2025-ODACC-Annual-Report-Final.pdf
• The Part II.1 (adjudication) and Part I.1 (prompt payment) provisions came into force on 1 October 2019. The Act's own in-force notes record '2017, c. 24, s. 11 (1) - 01/10/2019' against the Part II.1 sections and '2017, c. 24, s. 7 - 01/10/2019' against the Part I.1 sections. ODACC states the same date: 'Adjudication and prompt payment provisions of the Construction Act came into force on October 1, 2019.' Source: https://www.ontario.ca/laws/statute/90c30
• WHAT MAY BE ADJUDICATED — s. 13.5(1) (as amended effective 1 January 2026) permits a party to a contract to refer a dispute 'respecting any prescribed matter or any matter agreed to by the parties' to adjudication; s. 13.5(2) does the same for subcontracts. The prescribed matters are set out in O. Reg. 264/25, s. 19(1): the valuation of services or materials provided under the contract; payment under the contract, including in respect of a change order (approved or not) or a proposed change order; a dispute that is the subject of a notice of non-payment under Part I.1; amounts retained under s. 12 (set-off by trustee) or s. 17(3) (lien set-off); payment of a holdback under s. 26; and — only where reasonably necessary to resolve another adjudicable matter — the scope of work, a request for a change in the contract price, and a request for an extension of time. Source: https://www.ontario.ca/laws/regulation/250264
• Adjudication is time-limited at the front end: s. 13.5(3) bars an adjudication in respect of a contract 'if the notice of adjudication is given more than 90 days after the date on which the contract is completed, abandoned or terminated, unless the parties to the adjudication agree otherwise', with a parallel rule for subcontracts in s. 13.5(3.1). Section 13.5(4) limits an adjudication to 'a single dispute, unless the parties to the adjudication and the adjudicator agree otherwise.' Source: https://www.ontario.ca/laws/statute/90c30
• STATUTORY TIMELINE FOR A DETERMINATION — s. 13.13(1): 'an adjudicator shall make a determination of the matter that is the subject of an adjudication no later than 30 days after receiving the documents required by section 13.11.' Section 13.11 requires the party who gave the notice of adjudication to provide those documents 'No later than five days after an adjudicator agrees or is appointed to conduct the adjudication'. Section 13.13(2) permits extension — up to 14 days on the adjudicator's request with the parties' written consent, or for a period agreed in writing by the parties with the adjudicator's consent. Section 13.13(5): 'A determination made by an adjudicator after the date determined under subsection (1) or (2) is of no force or effect.' Section 13.13(6) requires the determination to be in writing with reasons. Source: https://www.ontario.ca/laws/statute/90c30
• A determined amount must be paid 'no later than 15 days after the determination has been communicated to the parties to the adjudication' (s. 13.19(2)). Judicial review of a determination is available only with leave of the Divisional Court (s. 13.18(1)). Source: https://www.ontario.ca/laws/statute/90c30
• PROMPT PAYMENT (Part I.1) — proper invoices 'shall be given to an owner on a monthly basis, unless the contract provides otherwise' (s. 6.3(1)). Owner to contractor: payment 'no later than 28 days after receiving the proper invoice from the contractor' (s. 6.4(1)), unless the owner gives a notice of non-payment 'no later than 14 days after receiving the proper invoice' (s. 6.4(2)). Source: https://www.ontario.ca/laws/statute/90c30
• PROMPT PAYMENT, down the chain — contractor to subcontractor: where the contractor is paid in full within the s. 6.4(1) time, it must pay each subcontractor 'no later than seven days after receiving payment' (s. 6.5(1)), and the same seven days applies to partial payment received (s. 6.5(2)). Where the owner does not pay, the contractor must pay its subcontractors 'no later than 35 days after giving the proper invoice to the owner' (s. 6.5(4)) unless it gives a notice of non-payment; that notice must include 'an undertaking to refer the matter to adjudication under Part II.1 no later than 21 days after giving the notice to the subcontractor' (s. 6.5(5)(a)(iii)). Subcontractor to sub-subcontractor: seven days after receiving payment (s. 6.6(1)). Source: https://www.ontario.ca/laws/statute/90c30
• ARBITRATION — the Act contemplates arbitration under the Arbitration Act, 1991 in four places, all of them treating arbitration as the forum that supersedes an interim adjudication rather than as a process the Act itself creates: s. 13.5(5) (a dispute may be referred to adjudication 'even if the dispute is the subject of a court action or of an arbitration under the Arbitration Act, 1991, unless the action or arbitration has been finally determined'); s. 13.15(1) (an adjudicator's determination 'is binding on the parties to the adjudication until a determination of the matter by a court, a determination of the matter by way of an arbitration conducted under the Arbitration Act, 1991, or a written agreement between the parties'); s. 13.15(2) (nothing in Part II.1 restricts 'the authority of a court or of an arbitrator acting under the Arbitration Act, 1991 to consider the merits of a matter determined by an adjudicator'); and s. 62(6)(b) (a lien claimant 'whose action was stayed by reason of an order under the Arbitration Act, 1991' may be let in to prove the claim). Source: https://www.ontario.ca/laws/statute/90c30
• DARLINGTON — the Darlington New Nuclear Project is real and is Ontario Power Generation's. OPG's own page describes it as 'leading the way in the advancement of Small Modular Reactor (SMR) technology in Canada' and states that on 7 July 2023 the Ontario government announced it would work with OPG 'to commence planning and licensing for three additional SMRs, for a total of four SMRs at the Darlington new nuclear site.' Source: https://www.opg.com/projects-services/projects/nuclear/smr/darlington-smr/
• DARLINGTON, status in the proponent's own words as at 2026-08-29: OPG's page states 'In March 2026, OPG applied to the Canadian Nuclear Safety Commission (CNSC) for a Licence to Operate (LTO) the first SMR', that the application 'is comprised of a number of packages, submitted to the CNSC over the course of several months' and 'will culminate in a public hearing'. Under the heading 'Site construction progress - Summer 2026' it states 'The construction of the reactor building is now progressing upwards towards grade following the successful basemat (the foundation of the Unit 1 reactor building) installation earlier this year.' It adds that 'Additional regulatory approvals will be required prior to construction and operation of additional units.' Source: https://www.opg.com/projects-services/projects/nuclear/smr/darlington-smr/
• DARLINGTON, corroborated by the regulator: the CNSC page states 'The site is owned by Ontario Power Generation (OPG)', 'The BWRX-300 is a 300 MWe water-cooled, natural circulation small modular reactor', 'OPG applied for a licence to construct 1 BWRX-300 reactor in October 2022 and was granted the licence in April 2025', 'In March 2026, OPG applied for a 20-year licence to operate 1 BWRX-300 reactor and an associated low- and intermediate-level waste storage structure', and 'Current status: 1 unit under construction'.

It states 'At the completion of the Planning Phase, Bruce Power received the Integrated Tailored Impact Statement Guidelines and Planning Phase documents from the IAAC and CNSC'. Bruce Power's newsroom release of 2025-08-21 states 'The planning phase of the federal Integrated Impact Assessment process has been completed for Bruce Power's Bruce C project' and that on 19 August the IAAC with the CNSC 'issued the formal Notice of Commencement of Impact Assessment under the Impact Assessment Act'.

• BRUCE C — no reactor technology has been chosen. Bruce Power states: 'Reactor technology has not been selected at this time, and the Impact Assessment for the Bruce C Project will be technology neutral.' It also states it 'has commenced a siting assessment' on the existing site. Bruce C is therefore at an assessment/optioning stage, not a construction stage — unlike Darlington, no construction licence exists. Source: https://engage.brucepower.com/brucec

What this does NOT establish

Read this section before writing copy. It is the half that keeps a page honest, and on this project it is the half that has twice been skipped.

• Does the Construction Act contemplate MEDIATION of construction disputes, and where?
  • Searched: Case-insensitive regex sweep for 'mediat' over the complete fetched text of the current consolidation (the full JSON payload from https://www.ontario.ca/laws/api/v2/legislation/en/doc-search/statute/90c30, 374,864 bytes, tags stripped), plus a read of the Part headings list and of Part VIII (Jurisdiction and Procedure).
  • Outcome: NO MEDIATION PROVISION FOUND. The sweep returned exactly 2 matches and both were false positives — 'in the immediate vicinity of the premises' (s. 1 definition of 'improvement') and 'the year immediately preceding the anniversary' (s. 26.1(4), annual holdback release). Both matches were printed and read. On the text retrieved, the Construction Act contains no mediation provisions at all: no mediation Part, no mandatory or court-annexed mediation step, no mediator role. There is nothing to quote because there is nothing there. This is a confirmed negative, not an unsearched gap — but it is stated as an absence in the statute only. Whether mediation of construction disputes is required or available by some OTHER instrument (for example the Rules of Civil Procedure, O. Reg. 194/90, or a standard-form contract such as CCDC 2) was NOT searched and must not be inferred from this.
• On what date, and by what instrument, was ODACC designated as the Authorized Nominating Authority?
  • Searched: O. Reg. 264/25 in full (searched for 'ODACC' and 'Ontario Dispute Adjudication' — zero matches; s. 2 sets designation eligibility criteria but names no entity); ODACC's home page, About Us page and 2025 Annual Report PDF (searched for 'designat', 'named', '2019'); s. 13.2 of the Act.
  • Outcome: NOT ESTABLISHED. ODACC's designation is made by the Minister under s. 13.2(1), not by regulation, and no primary or institutional source retrieved states the designation date. ODACC's own pages assert only that it IS the ANA, with no date. A third-party law-firm/news source surfaced in search asserts 18 July 2019, but that was not fetched or verified and is NOT relied on here. Do not publish a designation date.
• Verbatim confirmation of OPG's Darlington page by direct fetch of opg.com.
  • Searched: curl with a browser User-Agent and full navigation headers (HTTP 403, Cloudflare block, on both www.opg.com and opg.com); WebFetch on the same URL (HTTP 403). Text was then obtained through the r.jina.ai reader proxy (HTTP 200).
  • Outcome: PARTIAL. The OPG content quoted above came through a third-party reader proxy rather than a direct fetch, so the exact wording carries one hop of risk. Every load-bearing fact in it (proponent, BWRX-300 technology, construction licence April 2025, operating licence application March 2026, one unit under construction) is independently confirmed by the CNSC regulator page, which WAS fetched directly. Before any OPG wording is quoted on a public page, open the OPG URL in a browser and confirm the sentence.
• Whether the Darlington and Bruce C projects have any adjudication, lien, or prompt-payment activity under the Construction Act.
  • Searched: Not searched — outside the scope of the sources fetched.
  • Outcome: NOT ESTABLISHED, and nothing above supports connecting these two projects to the Construction Act machinery. The projects were verified as real and their status recorded; no source retrieved links either project to any dispute, adjudication, lien or payment proceeding. Do not use them as examples of ADR work, of the practitioner's involvement, or of anything else beyond 'these projects exist and are at these stages'.
• Whether the Construction Act's Part II.1 provisions quoted are affected by any not-yet-in-force amendment.
  • Searched: Searched the raw e-Laws payload for not-in-force markers ('not in force', 'ynote', NYIF classes). The consolidation's metadata flags "Contains 'not yet in force' provision sections".
  • Outcome: MOSTLY CLEARED, with one caveat. Two not-in-force items were found, both amendments from 2017, c. 33, Sched. 2, s. 76 (1) and (2), attached to s. 1 and s. 34 — neither touches the periods or the Part II.1 text quoted above. However, the full NYIF set was not exhaustively mapped section by section. Anything published from this artefact should be re-checked against the live e-Laws page on the day of publication, since this consolidation is current only 'to the e-Laws currency date'.
