- The short answer
- Six clocks, and they are not the same six on every job. Ask which Act governs before you diarise anything: the Prompt Payment and Construction Lien Act, RSA 2000, c P-26.4 on private and municipal work, or the Public Works Act, RSA 2000, c P-46 on provincial Crown public works.
- On a provincial Crown public work
- One clock dominates, Public Works Act s 14(3), 45 days from last supply, by registered mail, in the statutory form. There is no lien, no trust of the Crown's money, and delay is expressly not adjudicable under s 14.3(2).
- Contractual notice
- CCDC 2 – 2020 GC 6.5.4 gives 10 Working Days from the commencement of the delay for time. GC 6.6.1 requires only timely notice for money. Public and municipal forms differ sharply, and two of them carry de-minimis thresholds rather than day counts.
- Adjudication
- Private and municipal only. Referral is available up to 30 days after final payment under PPCLA s 33.4 and runs concurrently with litigation, which makes private Alberta the most open adjudication forum in Canada. There is no cap.
- Liens
- 60 days generally, 90 days for an oil or gas well or well site, 90 days for concrete other than ready-mix, a $700 minimum claim, and 180 days from registration to commence the action and file a certificate of lis pendens. Private and municipal work only.
- Limitation
- Two years from the three-limb discovery test in s 3(1)(a) of the Limitations Act, and a ten-year ultimate period running from the discrete first actionable breach. The parties may extend it by agreement. A clause shortening it is invalid under s 7(2).
- Prosecution, the clock nobody diarises
- Rule 4.31 dismisses for inordinate and inexcusable delay with prejudice, rule 4.33 is mandatory once three or more years pass without a significant advance. A $4M construction claim was struck in Peters v Countryside Masonry Inc, 2025 ABKB 713.
- The trap for visiting practitioners
- In Alberta a delay claim can meet every notice, adjudication, lien and limitation deadline and still be struck for being prosecuted too slowly. No other regime in this cluster works that way.
Alberta runs six clocks on a delay claim: contractual notice, adjudication, lien, holdback, limitation, and prosecution of the action itself. They have different characters in law, some are conditions precedent to entitlement, some are statutory preconditions to a remedy, one is a limitation period and one is a procedural rule and which of them exist at all depends on which Act the project sits under. On a provincial Crown public work most of them do not exist, and the 45-day registered-mail notice under the Public Works Act is effectively the only clock that matters.
The deadlines below are grouped by clock rather than by chronology, because a delay claimant is never running one clock at a time. A single Alberta project can have a 10-Working-Day contractual notice period, a 60-day lien period, a 28-day payment cycle feeding an adjudication referral, a two-year limitation period and a three-year drop-dead rule all running from different trigger events, none of which is the day the delay was noticed.
This page sits under the Alberta place hub, which carries the two Acts, the citation eras and the Alberta authority map. General Canadian doctrine: force majeure, concurrency, liquidated damages, prolongation quantum, lives at the Canada hub and is not repeated here. What is repeated, deliberately and in every section, is the Act, the section number and the date the regime took effect, because in Alberta the same provision had a different chapter letter before 29 August 2022 and the same court had a different name before 8 September 2022.
The first question is not what the deadline is, but which Act you are on
Alberta splits at the front door. Private and municipal work runs on the Prompt Payment and Construction Lien Act, RSA 2000, c P-26.4, which carries liens, the lien funds, the s 22 trust, prompt payment and adjudication. Provincial Crown public works run on the Public Works Act, RSA 2000, c P-46, where there are no liens, no trust of the Crown's money, and delay is expressly not adjudicable. That single fact decides which clocks exist before the contract form is even opened.
The exclusion is statutory and it is explicit. PPCLA s 1.1 excludes "public works" as defined in the Public Works Act and agreements with the provincial Crown or a Crown agent. So on an Alberta government job a delay claimant below first tier has no lien, no trust of the Crown's money and no substantive right under the Public Works Act only the contract claim against the party above it, plus the labour and material payment bond if there is one.
| Private and municipal | Provincial Crown public works | |
|---|---|---|
| Statute | PPCLA, RSA 2000, c P-26.4 | Public Works Act, RSA 2000, c P-46 |
| In force from | 29 August 2022 (Bill 37), Bill 30 (2024) amendments 1 April 2025 | Bill 30 (2024) prompt-payment provisions, contracts entered on or after 1 April 2025 |
| Liens | Yes, 60 or 90 days | None against provincial or federal Crown land |
| Trust | s 22, but only on payments received after a Certificate of Substantial Performance | No trust of the Crown's money |
| Delay adjudicable | By consent, under the s 19 catch-all, no monetary cap | Expressly excluded, s 14.3(2) |
| The gate | Contractual notice, then lien, then limitation | s 14(3): 45 days, registered mail, statutory form |
Jurisdictional layer. Both columns rest on secondary sources, no consolidated Alberta statutory text was read in original form for this corpus.
The Public Works Act exclusion is at s 14.3(2), added by Bill 30 (2024), the Service Alberta Statutes Amendment Act, 2024, in force 1 April 2025, and not to be confused with Bill 30 (2026), the Expedited 120-Day Approvals Act, whose status the corpus records as . Section 14.3(2) excludes from adjudication changes or delays to a construction schedule, completion or milestone dates, and disputes over the interpretation of relief events, designated changes in law, remedial actions and force majeure events. Every category an extension-of-time claim lives in is carved out by name. Nothing like it exists elsewhere in Canada.
What is left on a provincial job is s 14(3): notice within 45 days, by registered mail, specifying the nature and amount of the claim. It is enforced strictly. In Graham Construction and Engineering Inc v Alberta (Infrastructure), 2021 ABQB 184, decided by the Court of Queen's Bench, before the 8 September 2022 renaming, seventeen claimants who used the statutory form were paid and thirty-two, including Graham itself, were shut out. The claimants who succeeded were not the ones with the better delay case. They were the ones who used the form.
Character in law. The s 14(3) notice is a statutory precondition to the claim against the Crown, not a contractual condition precedent. It is not a limitation period either: it does not bar an action that is otherwise properly constituted against a private party up the chain, and it is not subject to the extension machinery in the Limitations Act. Practically, on a provincial job it does the work of all six clocks at once, and missing it cannot be repaired by the contract.
Contractual notice: the entitlement clock, and it changes with the form
The contractual notice clock decides entitlement, and Alberta has no single answer to it because Alberta has no single form. On private work the default is CCDC 2 – 2020 GC 6.5.4, written notice of a claim for extension of the Contract Time within 10 Working Days of the commencement of the delay, with GC 6.6.1 requiring only "timely" notice for the money claim, with no fixed period. The public and municipal forms are stricter, differently shaped, or silent.
| Form or provision | What the clock governs | The deadline |
|---|---|---|
| CCDC 2 – 2020 GC 6.5.4 | Time | 10 Working Days from the commencement of the delay |
| CCDC 2 – 2020 GC 6.6.1 | Money | "Timely", no fixed period |
| CCDC 2 + ACA supplementary conditions | Time | , whether ACA SC CCDC2-2020 amends GC 6.5 could not be established |
| Public Works Act s 14(3) | The whole claim | 45 days from last supply, by registered mail, statutory form |
| AB Infrastructure CM Agreement, Sch 19 Relief Event | Time and money | Prompt written notice, relief only above 10 Business Days and $10,000 |
| AB Infrastructure CM Agreement, force majeure | Time | 5 Business Days, either party may terminate if the event exceeds 120 days |
| AB Transportation Edition 16, s 1.2.39 | Time | Adjustment of completion dates. . No notice day count was extractable |
| City of Calgary GC v2.0, Art 6.2(5) | Time | Design Professional delay not considered unless more than 14 Days |
| City of Calgary GC v2.0, Art 7.2 | Time | "Immediately" on becoming aware the Scheduled Operational Date will be missed |
| City of Calgary GC v2.0, Arts 4.5(1) / 5.3(1) | Another contractor's defects | 1 Business Day to report. The City may remedy on 5 Business Days' notice |
Form-default layer. Clause numbers and headings are verified against publicly available sources, operative wording is reconstructed from converging secondary sources, and the Alberta Infrastructure, Alberta Transportation and City of Calgary readings are recorded as single-source.
Three of those rows are traps rather than deadlines. The Alberta Infrastructure Construction Management Agreement Schedule 19 gives relief only for time impact beyond 10 Business Days and cost exceeding $10,000, hard de-minimis filters, which make sub-threshold Province-caused disruption uncompensable and push a construction manager toward global or cumulative-impact framing and straight into the usual global-claim objections. The City of Calgary Standard General Conditions, Version 2.0 of 31 October 2022, do the same thing at Art 6.2(5): a contractor facing forty three-day design-response delays has, on the face of the clause, no extension at all, because no single delay exceeds 14 Days. And Art 7.2's "immediately" runs from awareness that the Scheduled Operational Date will be missed, not from the delay event, a clock that starts inside the contractor's own head.
The Alberta Transportation General Specifications, Edition 16 (2019) present the opposite problem. Sections 1.2.39 (adjustment of completion dates), 1.2.43 (seasonal or prolonged shutdown) and 1.2.57 (claims and dispute resolution) are identified, but . No notice-of-claim day count was extractable from Edition 16, and s 1.2.57 refers out to a 1997 government dispute document. On highway and bridge work the working assumption should be that a notice period exists and has not been located, serve early and in writing.
On CCDC 2 – 2020 the live Alberta question is the supplementary conditions. Across Canada supplementary conditions almost universally amend GC 6.5, and Ontario's industry-agreed package is the exception that leaves it alone. Alberta has no clean answer: whether the ACA SC CCDC2-2020 package amends GC 6.5 could not be established, and the corpus records this as the top Alberta verification gap. The file is distributed as a.docx, the site was unreachable, and a 2021 Advisory discussing Ready-for-Takeover and GC 5.4.5 holdback release is silent on GC 6.5, which is weak evidence rather than a finding. Read the executed supplementary conditions before relying on 10 Working Days. Separately, on Alberta industrial work there is no Alberta or Canadian standard EPC or EPCM form in common use, so CCDC 2 GC 6.5 will usually be irrelevant and there is no default extension-of-time clause to reason from at all.
Character in law. These are conditions precedent to entitlement, that is how the corpus classifies them and how Alberta pleadings run. But the supporting authority is thin, and the honest statement is a negative finding: there is no Alberta appellate authority beyond Dilcon Construction Ltd v ANC Developments Inc, 2000 ABCA 223 treating a contractual notice-of-claim clause as a condition precedent, and that case may not be a notice case at all, a substantial source attributes to the same judgment an implied term of uninterrupted possession of the site, which is a prevention-adjacent holding and a stronger tool for a claimant than a strict-notice rule. Sources also reverse the party order in the style of cause, the neutral citation is agreed. Both readings may be correct, which would leave Alberta with no appellate condition-precedent authority at all.
Notice cuts both ways, and the reported Alberta consequence has fallen on an owner as readily as on a contractor. In Tempo Alberta Electrical Contractors Co Ltd v Man-Shield Construction Inc, 2023 ABKB 44 the subcontractor obtained partial summary judgment of $678,261, and the general contractor's delay and staffing backcharge failed for want of written notice and an opportunity to cure. The delay damages themselves were expressly reserved for trial, which is consistent with the recorded finding that no Alberta decision has summarily dismissed or granted a delay claim itself: payment and lien claims go summarily in Alberta, delay claims do not.
Adjudication: the clock that reopens after final payment, and the clock that does not exist
On private and municipal work the PPCLA, RSA 2000, c P-26.4 runs a payment cycle whose deadlines feed an adjudication referral, and the referral window is the most generous in Canada: up to 30 days after final payment under s 33.4, and available concurrently with litigation, since 1 April 2025. On provincial Crown public works there is no adjudication of delay at all, because Public Works Act s 14.3(2) excludes it. The two regimes have to be read separately, and a sentence about Alberta adjudication that does not say which side of the line it is on is unsafe.
| Clock, private and municipal, PPCLA c P-26.4 | Deadline | Section |
|---|---|---|
| Proper invoice cycle | At least every 31 days, may be shortened but not lengthened | s 32.1(6) |
| Owner to contractor | 28 days from the proper invoice | s 32.2(1) |
| Owner's notice of dispute (Form 1) | 14 days from receipt | s 32.2(2) |
| Contractor to subcontractor | 7 days from receipt of the owner's payment | s 32.3(2) |
| Contractor to subcontractor where the owner has not paid | 35 days from the proper invoice | s 32.3(4) |
| Contractor's notice of non-payment (Form 2) | 7 days from the Form 1, or 35 days from the proper invoice. And it must contain an undertaking to adjudicate within 21 days | s 32.3(5) |
| Subcontractor to sub-subcontractor | 7 days / 42 days | ss 32.5(1), 32.5(5) |
| Subcontractor notices (Forms 4, 5) | 7 days from a Form 2 or 3, or 42 days from the proper invoice | s 32.5(8) |
| Adjudication referral | Up to 30 days after final payment, post-completion, and concurrent with litigation | s 33.4 |
| Judicial review of a determination | 30 days | s 33.7 or s 33.8 |
Jurisdictional layer, private and municipal work only. Section numbers rest on secondary sources, no consolidated Alberta statutory text was read in original form.
Two features of that table are unusual enough to change strategy. The first is the s 32.3(5) notice of non-payment, which must carry an undertaking to adjudicate within 21 days, the notice is not a holding position, it is a commitment to a forum. The prescribed notices themselves are Forms 1 to 5, and the corpus does not resolve whether they sit in the Prompt Payment and Construction Lien Forms Regulation, Alta Reg 51/2002, or in Alta Reg 23/2022. Check the regulation before serving.
The second is s 33.4. A referral available up to 30 days after final payment, and running concurrently with litigation, means Alberta private-sector adjudication is not the interim, in-project, cash-flow device it is elsewhere. It is a late-crystallising delay claim's most open door in the country, and the reason the one-sentence orientation for Alberta is that it is the best Canadian forum for a late-crystallising private delay claim and the worst for a public one. Delay itself is adjudicable on private and municipal work by consent, under the s 19 catch-all. The processes do not collapse into each other: Welcome Homes Construction Inc v Atlas Granite Inc, 2024 ABKB 301 holds that lien rights and adjudication are independent, and that a determination may be filed as an order of the court.
On the Public Works Act side, contracts entered on or after 1 April 2025 have their own payment clocks: proper invoices every 31 days, Crown to contractor 28 days, contractor to subcontractor 35 days, subcontractor to sub-subcontractor 42 days, all measured from the proper invoice. Two differences bite. The contractor must pay undisputed amounts at 35 days even if the Province has not paid it, and the PPCLA's notice-of-non-payment "stop the clock" mechanism is not available. So the payment clocks are tighter and the defensive machinery is thinner. And none of it gets a delay dispute to an adjudicator, because s 14.3(2) has already excluded it.
A monetary cap applies to Public Works Act adjudication only. There is no cap on PPCLA private-sector adjudication. The figure is : commentary glosses the cross-reference to Court of Justice Act (Alberta) s 9(1)(i) as $200,000, while the prescribed Alberta Court of Justice civil limit has been $100,000 since 1 August 2023, the Provincial Court having become the Alberta Court of Justice on 1 April 2023. Read s 9(1)(i) before printing either number. Two further recorded negative findings frame how much of this is untested: there is no reported Alberta judicial review of an adjudicator's determination, and the judicial-review section itself is as between s 33.7 and s 33.8, though the 30-day period is agreed. The regime is developed at prompt payment and adjudication in Alberta.
Character in law. The payment deadlines are statutory preconditions to a remedy they create the proper-invoice and notice architecture that a referral depends on, rather than barring the underlying claim. The 30-day judicial-review period is a procedural rule. None of them extends or preserves a limitation period, and none of them exists on a provincial Crown public work.
Liens and holdback: 60 days, 90 days, $700, and 180 days to perfect
The lien clock decides security, and it runs only on private and municipal work under the PPCLA, RSA 2000, c P-26.4. There are no liens against provincial or federal Crown land. The period is category-dependent: 60 days generally, 90 days for an improvement to an oil or gas well or well site, and 90 days for concrete other than ready-mix. A registered lien then has to be perfected within 180 days.
| Clock | Deadline |
|---|---|
| Lien registration, general | 60 days |
| Lien registration, oil or gas well or well site | 90 days |
| Lien registration, concrete, excluding ready-mix | 90 days |
| Minimum lien claim | $700 |
| Enforcement action plus certificate of lis pendens | 180 days from registration |
| Non-general-contractor claimants to reach the major lien fund | 60 days from the Certificate of Substantial Performance being posted |
| Major lien fund retention | 60 days after the CSP, or after completion if there is none, 90 days for oil and gas and for concrete |
| Minor lien fund retention | 60 days after completion of the prime contract, 90 days for the special categories |
| Progressive holdback release, s 24.1 | Annually, where the contract exceeds $10,000,000 and runs more than one year without a milestone regime. notice mechanics |
Jurisdictional layer, private and municipal work only. Day counts and thresholds rest on secondary sources. No consolidated Alberta statutory text was read in original form.
Two structural points matter more than the numbers. The first is that the lien fund is not the trust. The major and minor lien funds are owner-held security, each split into Part A, the 10 per cent statutory holdback, and Part B, the amount payable. The trust is a separate mechanism at PPCLA s 22, and it arises only on payments received after a Certificate of Substantial Performance ATB Financial v DLM Oilfield Enterprises Ltd, 2020 ABQB 562, decided under the Builders' Lien Act, RSA 2000, c B-7, as it then was. A delayed project that is terminated or abandoned before substantial performance has no trust at all, which is precisely the fact pattern delay claims arise in.
The second is what a delay claim can actually put into the lien. Krupp Canada Inc v JV Driver Projects Inc, 2014 ABQB 259, again under the Builders' Lien Act, RSA 2000, c B-7, holds that delay damages form part of a lien only where they relate directly to the work that is the subject of the lien: lost productivity on the liened project yes, inability to work elsewhere no. the corpus records disagreement on what Krupp holds, one Alberta source reading it as permitting lienable delay damages and a substantial international source indexing the same decision for the opposite proposition, and the later, narrower PME Inc v Enerkem Alberta Biofuels LP, 2021 ABQB 889 does not cite it. There is no appellate resolution, so the line is factual rather than categorical. Note the chapter letter on both: every Alberta lien and delay authority before 29 August 2022 cites c B-7, and a search that only indexes c P-26.4 silently drops most of the useful material.
The holdback clock is separate from the lien clock and easy to miss on a long delayed project. PPCLA s 24.1 provides for progressive release, by default annually, where the contract exceeds $10,000,000 and runs more than one year without a milestone regime, but the notice mechanics could not be established: whether a notice of intention to release must be published or served, and on whom, and whether each release starts a fresh 60-day lien period for the released phase. On a multi-year Alberta project that gap sits directly on top of the lien clock. The security analysis is developed at liens, the lien fund and trust in Alberta.
Character in law. Lien registration is a statutory precondition to the existence of the security, not a limitation period on the debt: losing the lien does not lose the contract claim, and it does not lose an adjudication referral, which Welcome Homes Construction Inc v Atlas Granite Inc, 2024 ABKB 301 confirms runs independently. The 180-day perfection requirement operates as a hard extinguishing period on the registered lien itself.
Limitation: two years, ten years, and a floor the contract cannot lower
The Limitations Act (Alberta) sets a two-year basic period running from the three-limb discovery test in s 3(1)(a), which includes, distinctively, whether the injury "warrants bringing a proceeding", and a ten-year ultimate period. The parties may agree to extend a limitation period under s 7(1). They may not shorten one: s 7(2) makes a reduction clause invalid. That is the opposite of the Ontario position, where a limitation period in the supplementary conditions can lawfully be shortened, and it is one of the sharpest differences a practitioner crossing the border will meet.
| Clock | Deadline |
|---|---|
| Basic period | 2 years from the s 3(1)(a) three-limb discovery test, including whether the injury warrants bringing a proceeding |
| Ultimate period | 10 years from when the claim arose, running from the discrete, first actionable breach |
| Contractual variation | Extension only, s 7(1). A clause shortening the period is invalid under s 7(2) |
| Arbitration | Limitation periods apply, and filing in court does not stop time |
Jurisdictional layer. Section numbers and day counts rest on secondary sources, no consolidated Alberta statutory text was read in original form.
The ultimate period is where a long-running delayed project gets caught. In Living Waters v UFA, 2025 ABKB 319, recorded in the corpus as and expressly , labels that should be carried in print rather than dropped, and of which the corpus records only this short style of cause, the ten-year period was held to run from the discrete, first actionable breach rather than from a continuing or later-crystallising state of affairs. On a project where the first defective instruction, first denied extension or first suspension is years earlier than the final account dispute the claim is really about, that characterisation can extinguish the claim while the parties are still negotiating.
The arbitration point catches people who think they have started something. In Lafarge Canada Inc v Edmonton (City), 2013 ABCA 376 the Court of Appeal held that limitation periods apply to arbitration and that filing in court does not stop time running for arbitration purposes. Where the contract has an arbitration clause and the claimant issues a statement of claim as a protective step, the protective step protects the wrong proceeding.
Two absences are worth stating flat. There is no Alberta equivalent of Ontario's invoice-and-default accrual rule for construction claims, so an Alberta claimant cannot borrow the Ontario accrual analysis. And Alberta's discovery test, unlike a pure knowledge test, imports a proportionality judgment through the "warrants bringing a proceeding" limb, which is a reason to date the clock from the record rather than from argument. The accrual analysis is developed at limitation periods in Alberta.
Character in law. These are true limitation periods. They bar the remedy rather than the entitlement, they are the only clock on this page the parties can lawfully extend by agreement, and they are the only one the parties cannot lawfully shorten.
After the award: 30 days, and the stamp that starts it
Two arbitration clocks run after a delay dispute has been decided. Permission to appeal is required and is available on a question of law only, under Arbitration Act (Alberta) s 44(2) and (2.1). The appeal must be commenced within 30 days of receipt of the award under s 46(1), and in Frog Lake First Nation v 2250657 Alberta Ltd, 2025 ABKB 206, that period was held to run to the clerk's "FILED" stamp rather than to the moment of submission. Filing late in the day at the end of the period is not the same as filing.
Expect the permission application to fail on a schedule finding. In Quanta Canada Holdings II ULC v Bremar Construction Ltd, 2024 ABKB 317: a Calgary duct-bank project with an $8,137,116 delay-and-defects claim permission to appeal was refused because delay causation is mixed fact and law, so no question of law arises under s 44(2). Arbitrating an Alberta delay dispute is choosing finality on the schedule findings, and the corpus records that no Alberta decision from 2020 to 2026 set aside or varied an arbitral award on a construction delay finding: every located Alberta construction-arbitration decision in the window is pro-finality. Forum choice is developed at arbitration and forum in Alberta.
Character in law. The 30-day appeal period is a procedural rule with a statutory source. It does not preserve anything: an award that is not appealed within it is final on the delay findings, whatever the limitation position on the underlying claim.
The clock nobody diarises: dismissal for delay under rules 4.31 and 4.33
Alberta dismisses construction actions for being prosecuted too slowly, and this is the clock that ends claims which met every earlier deadline. The Alberta Rules of Court run two mechanisms. Rule 4.31 permits dismissal for inordinate and inexcusable delay causing significant prejudice, it is discretionary, and prejudice is presumed on long delay. Rule 4.33 is the drop-dead rule: dismissal where three or more years pass without a significant advance in the action, and it is mandatory once triggered.
The authority is recent and it is a construction case. Peters v Countryside Masonry Inc, 2025 ABKB 713 struck a construction claim of approximately $4 million for inordinate delay, and the answer to the defence every construction claimant reaches for is that "construction is complex" is not an excuse. A schedule dispute with thousands of documents, several third parties and an expert on each side is exactly the kind of action that drifts past three years without a significant advance, and the rule does not make an allowance for it.
None of the six Alberta clocks saves any of the others. And in Alberta the sixth catches people who did the first five correctly.
Nothing in the Alberta forum will manage the pace for a claimant. The corpus records it flat: Alberta has no specialist construction list, no construction judges and no construction practice note, and the Commercial List is insolvency-only. A construction delay action is a general civil action, carried at whatever pace the parties carry it.
The trial-preparation clocks compound the same problem, because they are sequenced rather than dated. Expert evidence is served in Form 25 under rr 5.34 and 5.35, in sequence: primary burden first, then rebuttal, then surrebuttal limited to new issues with reasonable notice of admissibility objections under rr 5.36 and 5.37 and pre-trial questioning of an expert only by agreement or court order. Under r 8.4 reports are ordinarily exchanged before the trial date is set. And r 8.16(1) limits a party to one expert per subject matter unless the Court orders otherwise, with r 8.16(2) allowing the Court to direct which of several affiliated corporate parties may call the expert. The corpus records r 8.16 as and says to verify it against the Rules. Whether schedule and quantum are one subject matter or two is a decision to take early, not at the pre-trial conference. Two further absences are recorded: Alberta has no rule imposing a separate signed expert certification of duty to the court, and no fixed day count for service of expert reports.
Character in law. These are procedural rules of court, not limitation periods and not conditions precedent. Rule 4.31 is discretionary and rule 4.33 is mandatory once its three-year trigger is met, and neither is affected by the strength of the underlying delay claim, the size of it, or compliance with any statutory or contractual deadline that came before.
Six clocks, and none of them saves any of the others
The clocks are independent, they run from different triggers, and satisfying one is not evidence of having satisfied another. Contractual notice decides entitlement, and on a provincial job the Public Works Act s 14(3) notice replaces it and is stricter. Adjudication decides forum, and only on private and municipal work. The lien decides security, at 60 or 90 days. The holdback decides cash flow, annually only above $10,000,000 and one year. Limitation decides whether the claim can be sued on, and cannot be shortened by contract in Alberta. Prosecution decides whether the claim already filed survives.
The interactions are where the losses happen, and the following are inferences drawn from the clocks as tabulated rather than propositions any Alberta court has stated in these terms. A Public Works Act s 14(3) notice runs 45 days from last supply, while a contractual delay notice runs 10 Working Days from the commencement of the delay two unrelated triggers, one keyed to the end of the work and one to an event during it, so on a provincial job neither notice satisfies the other and serving the contractual notice on time tells you nothing about whether the statutory notice is still open. A PPCLA s 33.4 referral is available up to 30 days after final payment, but the Limitations Act two-year period is not extended by the availability of that forum, the most open adjudication window in Canada can sit inside a limitation period that has already run. And a lien that expires does not take the contract claim with it, while a limitation period that expires takes everything.
Two citation checks before any of this is researched further, because both silently break
Alberta research. The Court of Queen's Bench became the Court of King's Bench on
8 September 2022 (mid-year, not at the year boundary) so Alberta 2022 carries both
2022 ABQB nnn and 2022 ABKB nnn, and an ABQB citation dated 2023 or later is almost
certainly a transcription error for ABKB that should not be propagated, Masters and
Masters in Chambers became Applications Judges in the same period, which matters because
much of the Alberta lien-and-delay jurisprudence is Master-level. And the PPCLA is the
renamed Builders' Lien Act, RSA 2000, c B-7, renamed by Bill 37 in force
29 August 2022, so every Alberta lien and delay authority before that date, Krupp,
PME v Enerkem, ATB Financial v DLM among them, is cited to c B-7, and c P-26.4 is
correct only from 29 August 2022.
The point to carry off this page is the one that has no analogue anywhere else in this cluster. A delay claim in Alberta can serve every contractual notice on time, meet the 45-day statutory notice on a provincial job, register and perfect its lien, refer to adjudication inside the most generous window in the country, and issue well inside both the basic and ultimate limitation periods. And then be struck under rule 4.33 because three years passed without a significant advance. Every other clock on this page is a deadline for doing something. The sixth is a deadline for continuing to do it, and it is the one Alberta construction claims die on.

In this article
- The first question is not what the deadline is, but which Act you are on
- Contractual notice: the entitlement clock, and it changes with the form
- Adjudication: the clock that reopens after final payment, and the clock that does not exist
- Liens and holdback: 60 days, 90 days, $700, and 180 days to perfect
- Limitation: two years, ten years, and a floor the contract cannot lower
- After the award: 30 days, and the stamp that starts it
- The clock nobody diarises: dismissal for delay under rules 4.31 and 4.33
- Six clocks, and none of them saves any of the others
