Quebec vs common-law Canada: what a common lawyer gets wrong about delay

Quebec is a civil-law jurisdiction inside a common-law federation. The operative consequence for delay work is blunt: the Code civil du Québec supplies no completion date, no extension-of-time mechanism and no delay regime at all in the contract of enterprise, and the doctrines that fill that space elsewhere in Canada (time at large, concurrent delay, constructive acceleration, the penalty rule) are absent as well. Time in Quebec is entirely a creature of contract, and the delay argument is conducted in the general law of obligations. The starting point for the statutory picture is the Civil Code framework for delay in Quebec. The starting point for the whole cluster is the Quebec extension-of-time hub.

One methodological warning governs everything below. The Code civil and Code of Civil Procedure articles on this page are primary-verified against LégisQuébec in French and in the official English, and can be relied on as stated. Every Quebec judgment on this page is different. CanLII, SOQUIJ, CAIJ and RIM were all inaccessible to the research behind this corpus, and no Quebec judgment was read in original text. Case names, neutral citations, holdings and every quantum figure rest on law-firm bulletins. Each table below says which of its rows rest on the Code and which rest on secondary case commentary, because on this page that distinction is the difference between a proposition you can plead and one you must verify first.

The doctrines a common lawyer reaches for, and what Quebec has instead

Four load-bearing common-law delay doctrines do not exist in Quebec: time at large, concurrent delay, constructive acceleration and imprévision. None of these is an open question. Each is a recorded negative finding, searched for and not found. Quebec resolves the same problems through fault, causation, apportionment and abuse of right, and the practical results are often similar, but the route, the pleading and the evidence are not.

Start with the one that costs the most: there is no "time at large" in Quebec. No Quebec source (statutory, judicial, doctrinal or professional) uses the concept or any French equivalent. The concept has no structural place, because there is no statutory completion date for a court to set at large and no default obligation to fall back on. Where a term is indeterminate, art 1512 C.c.Q. requires the court, on the application of either party, to fix the term having regard to the nature of the obligation and the circumstances. That is the opposite consequence to the common-law one: judicial gap-filling rather than collapse of the date. And the penalty does not fall away with the date. It is defeated on the merits where the owner was at fault or suffered no prejudice, or reduced under art 1623 para 2 C.c.Q. A defective extension mechanism in a Quebec contract is therefore not the windfall a common-law practitioner expects, and pleading time at large in Quebec signals to the court that counsel has not read the Code.

The absence runs deeper than one doctrine. The C.c.Q. contains no provision on time for completion, delay, or extension of time in the contract of enterprise. Every article of arts 2098–2129 C.c.Q. was read individually for this corpus. There is no default completion rule, no statutory extension mechanism, no list of excusable events, no delay-notice regime and no delay-damages regime. Time appears once, at art 2102 C.c.Q., and it is a pre-contractual disclosure duty on the contractor as to the time necessary.

On concurrency, Quebec apportions. No Quebec authority, doctrine or professional commentary on « délais concomitants » or « retards concurrents » as a distinct doctrine was located. The question is resolved through apportionment of fault, with reported outcomes of two-thirds owner liability in one Superior Court case and 636 delay days reduced to 475 in Ville de Pointe-Claire c. Asphalte Béton Carrières Rive-Nord inc. 2023 QCCA 1565. Art 1478 C.c.Q. supplies the apportionment principle, but it sits in the extracontractual chapter and art 1458 para 2 forbids co-contractants opting into that regime. Quebec courts apportion in contract regardless, and it should not be cited as though its contractual application were settled. The full treatment is on the Quebec concurrent-delay page, and the five competing models Quebec is not using are set out in the neutral treatment of concurrent delay.

On hardship, the trap is assuming Quebec follows France. It does not. Imprévision (relief where an unforeseeable change makes performance excessively onerous) was expressly rejected by the Supreme Court in Churchill Falls (Labrador) Corp v Hydro-Québec 2018 SCC 46: the doctrine "is not recognized in Quebec civil law at this time", and any development of analogous concepts "must take account of the legislature's choice not to turn this doctrine into a universal rule". France codified the opposite position at art 1195 of its Code civil in 2016. A practitioner reasoning from French civil law to Quebec will be wrong on this, and expensively so.

On prevention, Quebec has no named doctrine but three functional equivalents that reach the same result: abuse of right under arts 6, 7 and 1375 C.c.Q., applied in Constructions ConCreate ltée c. Procureure générale du Québec 2020 QCCA 570 and Ville de Québec c. Constructions BSL inc. 2022 QCCA 1682. Fault, causation and apportionment, and the discretionary fin de non-recevoir (a peremptory exception on the merits that permanently paralyses an otherwise existing right of action) recognised in Banque Nationale du Canada c. Soucisse [1981] 2 S.C.R. 339. State the caveat rather than glossing it: no Quebec judgment expressly using the words fin de non-recevoir in a construction delay context was located. The doctrine is squarely established in Quebec private law generally and the construction outcomes are functionally identical, but the terminological link is an inference, not a labelled line of cases.

Two smaller absences complete the group, and both push the practitioner back to the contract. No C.c.Q. provision states that force majeure suspends an obligation or extends time for its performance. The Code text is extinctive: art 1693 C.c.Q. speaks of the debtor being released where performance has become impossible. The suspensive effect that everyone in the industry assumes is doctrinal and contractual: it comes from the delay clause, for instance CCDC 2 – 2020, GC 6.5.3, which lists labour disputes, fire, unavoidable casualties and abnormally adverse weather and gives time without money. And there is no located Quebec analogue to the certifier's duty to act fairly and impartially familiar from Sutcliffe and Costain v Bechtel. What Quebec has instead is the professional's solidary liability by statute, and a contractual requirement that the extension be determined in consultation with the contractor. Note that the operative wording of the Quebec-specific CCDC 2CcQ – 2024 GC 6.5 is not publicly available and is uncommented in accessible sources, so its notice period cannot be stated.

Layer, jurisdictional and comparative. The Quebec column rests on the Code for arts 1512, 1623, 1693 and 2098–2129 C.c.Q., all primary-verified against LégisQuébec in French and official English, on recorded negative findings for the four absent doctrines, and on secondary law-firm commentary for every case named, none of which was read in original text. PG4 c. Énergir is under appeal, filed 18 December 2024. The common-law column is a summary of the comparator position and is not a statement of the law of any single province.

Where the risk actually sits: the burden, the fixed price and force majeure

Three Quebec rules move risk onto the contractor in ways a common-law contract does not. Once the contractor is in demeure (in default) it answers for force-majeure losses, so burning float can forfeit the defence entirely. Meeting the date is an obligation de résultat, so the contractor must positively prove its excuse. And on a forfait (lump-sum) contract, the price does not move even when the conditions of performance do.

The force-majeure rule is the one with no common-law analogue at all. Art 1600 para 2 C.c.Q. makes the debtor answerable, from the moment of default, for any loss resulting from force majeure, unless it is then released. Art 1470 C.c.Q. defines the excuse, and the Code's own term for it is "superior force": force majeure in the French text, not cause étrangère, which is a doctrinal expression the Code does not use. Superior force is an unforeseeable and irresistible event, and an external cause counts only where it presents those same characteristics. The article does not refer to the fault of a third person: a third party's act qualifies only if it is itself unforeseeable and irresistible, which ordinary owner or subcontractor interference is not. Art 1600 para 2 is therefore not a source of excuse but an exception that defeats it once the debtor is in default. Put those two articles together and the consequence is that float consumption in Quebec is legally consequential, not merely commercially inconvenient. Coffrage Alliance ltée c. Procureure générale du Québec 2018 QCCS 3782 is the reported illustration: the contractor was roughly ten days late when a post-tropical cyclone produced flooding that the court accepted as unforeseeable, and the claim failed anyway.

The burden runs the other way from what a Malmaison analysis assumes. Per Ville de Pointe-Claire c. Asphalte Béton Carrières Rive-Nord inc. 2023 QCCA 1565, meeting the completion date is an obligation de résultat (an obligation of result rather than of means) so delay presumes contractor responsibility, and the contractor displaces the presumption only by positively proving force majeure or the owner's fault. Proving the absence of its own fault is not enough. A period of genuinely mixed causation that neither side proves therefore defaults against the contractor.

The price rule closes the third door. Art 2109 C.c.Q. provides that on a forfait contract the contractor may not claim an increase of the price, and that the price remains unchanged notwithstanding any modification of the original terms and conditions of performance unless the parties agree otherwise. Escalation in steel, fuel, lumber or wage rates is the contractor's risk absolutely, and (read with the rejection of imprévision) there is no hardship route out. A Quebec prolongation claim therefore cannot be pleaded as "additional payment under the contract". It must be pleaded as an agreed avenant (an amendment, which Quebec appellate authority accepts may be verbal) or as damages for the owner's fault under art 1458 C.c.Q., for breach of the duty to inform, or for abuse of right.

Layer, jurisdictional. Every row in the Quebec column rests on the Code: arts 1458, 1470, 1594, 1597, 1600, 1693, 2101, 2103 and 2109 C.c.Q., all primary-verified against LégisQuébec in French and official English. The two case names in the Quebec column, Coffrage Alliance and Pointe-Claire, rest on secondary law-firm commentary. The reported facts and figures behind them were not read from the judgments.

Two clocks: the contractual time bar and prescription run independently

Quebec prescription is generous and the contractual time bar is savage, and the two have almost nothing to do with each other. Art 2925 C.c.Q. gives three years and art 2116 C.c.Q. defers the start to fin des travaux. But that generosity is no answer at all to a contractual claim deadline, because a claim procedure is not a prescription period. Both clocks run, and they are independent.

Take the contractual clock first, because it is the one that kills claims. Quebec courts enforce claim procedures strictly, on the reasoning that the owner must be able to address problems in real time. There are exactly three ways round it in the reported material (waiver, breach of the duty to inform, and breach of good faith) plus the characterisation escape in Procureur général du Québec c. Opron inc. 2022 QCCA 98, where a verbal agreement to accelerate took the claim outside the claim procedure altogether, because a claim under an amendment is not a "claim" within the clause. The good-faith route is PG4 Construction Corp. c. Énergir 2024 QCCS 4179, reported as awarding over $15 million despite the contractor's procedural default and the absence of waiver: and it is under appeal, filed 18 December 2024, so it cannot be relied on as settled. The mechanics, the clause periods by form and the escape routes ranked are on the Quebec notice and time-bars page.

Now the two propositions that a common-law practitioner will get backwards. Art 2884 C.c.Q. provides that no period of prescription other than that provided by law may be agreed upon. That prohibits any conventional period (shortening as well as lengthening) which is the reverse of Ontario, where the Limitations Act, 2002 permits variation of limitation periods in business agreements. It looks, at first sight, like a weapon against a 10-day or 120-day claim bar. It is not. Construction Infrabec inc. c. Paul Savard, Entrepreneur électricien inc. 2012 QCCA 2304 is reported as holding that a contractual claim deadline creates neither a peremptory time limit nor a public-order forfeiture, that the 120 days do not constitute a period of prescription, and that such periods cannot be assimilated to extinctive prescription. The reason is structural: on a lump-sum contract the claims procedure creates a right the contractor would not otherwise have, rather than extinguishing one. So art 2884 is not engaged by a construction claim procedure at all, and the argument should be abandoned.

Prescription in Quebec is generous, and it is no answer to a contractual time bar. Art 2884 C.c.Q. bans conventional prescription periods. Infrabec holds that a claim procedure is not one. Both clocks run, independently, and a claim can be perfectly within prescription and perfectly dead.

The prescription clock itself is worth getting right, because two errors are widely repeated. Art 2116 C.c.Q. does not run from acceptance, and it is not a warranty provision. It is a deferral provision, and it runs from fin des travaux (the end of the work) even with respect to work that was the subject of reservations at the time of acceptance. And fin des travaux is a statutory, objective state under art 2110 C.c.Q. (the work executed and in a state to serve according to its intended use) determined by the court, not by a certifier, and legally distinct from réception, the juridical act by which the client declares it accepts the work with or without reservation. On a project with a long tail of punch-list work the effective window is substantially longer than a common-law practitioner will assume. It also drives the deadlines on the hypothèque légale and the five-year liability for loss of the work under art 2118 C.c.Q., which is solidary. The one-year garantie contre les malfaçons under art 2120 C.c.Q. runs instead from réception, and is joint.

The last row in this group is the one that most often rescues a claim. The obligation de renseignement (the duty to inform) flows from codified good faith at art 1375 C.c.Q. and was set out in Banque de Montréal c. Bail Ltée [1992] 2 R.C.S. 554, a construction case. Three elements are reported: knowledge, actual or presumed, of the information, the determinative nature of that information for the other party, and the impossibility for that party of informing itself, or its legitimate reliance. Two features make it valuable in a delay file: the duty runs during performance, not only at formation, and it is not defeated by an exculpatory or "verify for yourself" clause. It is the functional Quebec equivalent of the US superior-knowledge doctrine, and broader, because it rests on a general codified obligation rather than a procurement-specific rule.

Layer: mixed, and the distinction matters here more than anywhere on the page. Rows 1, 2 and 6 rest on the Code: arts 2110, 2116, 2884 and 2925 C.c.Q., primary-verified against LégisQuébec in French and official English. Rows 3, 4 and 5 rest on secondary law-firm commentary about appellate judgments: Infrabec, 2012 QCCA 2304, Opron, 2022 QCCA 98, and Bail, [1992] 2 R.C.S. 554: none of which was read in original text, and none of which is given a paragraph pinpoint for that reason.

Delay penalties, adhesion and the owner's exits

Quebec has no penalty-versus-liquidated-damages characterisation question. A clause pénale is valid, enforceable without proof of the amount of loss, and reducible, never void. The owner still has to prove liability, so a contractor that shows the owner suffered no prejudice at all can defeat the clause outright. And two owner exits have no common-law counterpart: the client may resiliate unilaterally by operation of law, and it may not terminate for a trivial default however the contract is drafted.

The characterisation point is the one that changes how a file is run. Under arts 1622 and 1623 C.c.Q., the penal clause is the parties' anticipatory assessment of damages, the creditor is entitled to the stipulated amount without having to prove the injury suffered, and the amount may be reduced where the creditor has benefited from partial performance or where the clause is abusive. Two consequences follow. First, there is no all-or-nothing outcome: a Quebec court reduces, it does not strike down, and art 1623's reduction power is available in any contract, not only a contract of adhesion, which matters because the art 1437 C.c.Q. nullity route requires winning the adhesion argument first. Second, art 1622 permits the creditor to claim both performance and the penalty where the penalty is stipulated for delay alone, which is a drafting instruction as much as a rule: a delay penalty must be drafted as being for delay alone or the owner risks being put to an election.

What the owner still has to prove is the most important open point. Art 1623 para 1 removes proof of quantum, not of liability. Ville de Québec c. Constructions BSL inc. 2022 QCCA 1682 is reported as holding that the absence of prejudice defeats a claim founded on a penal clause, and that including a penalty clause in the tender documents does not guarantee its enforceability. The reconciliation to carry is that a penal clause substitutes conventional damages for judicially assessed damages, and both still require proof of fault, prejudice and causation under the ordinary rules of civil responsibility. Abusiveness is then assessed ex post rather than ex ante: the question is not whether the clause was reasonable when drafted but whether its complete application has become excessive on the facts. EBC inc. c. Ville de Montréal 2026 QCCS 855 is the leading recent construction application, reported as reducing a penalty from $2,997,500 to $2,000,000 on a 193-day delay for which the contractor bore sole responsibility: the clause not intrinsically abusive, but its full application producing enrichment beyond its compensatory and dissuasive role. The full set of attack routes is on the Quebec page on delay penalties and the clause pénale.

Adhesion is the second surprise. Under art 1379 C.c.Q. a contract is one of adhesion where its essential stipulations were imposed or drawn up by one party and were not freely negotiable, and note what the test is not: it is not a consumer test and it requires no inequality of bargaining power, small size or unsophistication. Hydro-Québec c. Terrassement St-Louis inc. 2025 QCCA 900 is reported as confirming that a public-body construction contract met that definition, and as holding the arbitration clause unfair under art 1437 C.c.Q. as an unreasonable obstacle to justice, on proportionality and the economic realities of the parties. EBC, on the other hand, declined to characterise a City of Montreal contract as one of adhesion, stressing lowest-compliant-bidder procurement and that the contractor had itself negotiated the relevant cap. The two are coherent because adhesion under art 1379 is fact-specific: evidence that the specific clause was negotiated defeats the argument.

The two termination rows are pure Code, and both are traps for a common-law draft. Art 1604 para 2 C.c.Q. provides, notwithstanding any stipulation to the contrary, that there is no right to resolution or resiliation where the debtor's default is of minor importance, although repeated small defaults in a contract of successive performance do justify resiliation, and art 1605 C.c.Q. permits extrajudicial resiliation where the debtor is in default by operation of law. A clause allowing termination for any delay however trivial is ineffective to that extent. And art 2125 C.c.Q. gives the client a unilateral right to resiliate the contract without cause, by operation of law, even after the work has begun. Termination for convenience in Quebec is statutory, not contractual. Compensation follows arts 2126–2129 C.c.Q., and whether future profit is recoverable under art 2129 is recorded as an unresolved conflict, the verbatim text of arts 2126–2129 not having been retrieved for this corpus. A live delay claim can be cut short by resiliation, at which point the contractor's recovery converts from contractual damages to the art 2129 measure.

Layer, mixed. Rows 4 and 5 rest entirely on the Code, arts 1604, 1605, 2125 and 2126–2129 C.c.Q., primary-verified against LégisQuébec, save that the verbatim text of arts 2126–2129 was not retrieved and the future-profit point under art 2129 is recorded as an unresolved conflict. Rows 1 and 3 rest on the Code for the article text and on secondary law-firm commentary for the cases. Row 2 rests wholly on secondary case commentary: BSL, 2022 QCCA 1682 and EBC, 2026 QCCS 855 were not read in original text, and the money figures are single-source.

Quantum, experts and proof

The vocabulary of common-law quantum does not transfer. No Quebec judgment names Eichleay, Hudson or Emden, none names a delay-analysis methodology at all, and "réclamation globale" is not Quebec vocabulary. What Quebec has instead is a foreseeability rule with a carve-out that has no common-law analogue, a statutory interest top-up that is routinely under-pleaded, a one-expert-per-discipline cap, and a demand that the critical-path link be proved item by item.

The overhead point is where the most money is lost. Head-office overhead is recoverable in principle in Quebec, on the same absorption logic that underlies Eichleay, but no Quebec judgment naming Eichleay, the Hudson formula or the Emden formula was located, and no Quebec practitioner text asserts that any has been adopted. Recovery runs instead on a contractual percentage, or an average proved from audited financial statements. Two percentages circulate: Aluminerie Alouette inc. c. Constructions du St-Laurent [2003] R.J.Q. 2663 at 15%, and Dawcolectric inc. c. Hydro-Québec 2014 QCCA 948 at 13.76% for overhead and profit, and both figures are recorded as unverified and single-source. Use them to calibrate an expectation, not to price a claim. The practical instruction is to build the percentage from your own audited accounts and be ready to prove it.

The foreseeability rule has a limb with no common-law counterpart. Art 1613 C.c.Q. confines contractual damages to what was foreseen or foreseeable at formation and, even then, to what is « une suite immédiate et directe » of the non-performance: except where the failure to perform is due to intentional fault or faute lourde, in which case the foreseeability filter falls away entirely and only the immediate-and-direct limit survives. At common law the Hadley limbs are not disapplied for deliberate breach. On a delay file this is a real lever: an owner that deliberately withholds access is exposed to the full unfiltered chain of direct loss. Note also the two articles that construction commentary routinely misuses: art 1612 C.c.Q. is the trade-secret article and art 1614 C.c.Q. is the discount rate for prospective bodily-injury damages. Neither has anything to do with construction quantum. The general provisions are arts 1607, 1611 and 1613 C.c.Q.

The under-pleaded item is the interest uplift. Art 1619 C.c.Q. permits the court to add an indemnity to the interest (the indemnité additionnelle) computed by applying a percentage equal to the excess of the rate fixed for Crown claims over the agreed or legal rate. There is no common-law equivalent, and on a multi-year delay award the difference is material. Art 1618 C.c.Q. makes interest on damages other than money debts run from default or from any later date the court considers appropriate, so the start date is itself discretionary and is a quantum battleground. In the other direction, art 1621 C.c.Q. requires a statutory basis for punitive damages, so there is no Quebec analogue to a general bad-faith-breach award. What exists is a modest head for troubles, ennuis et inconvénients (trouble, inconvenience and annoyance) reported at $10,000 in Construction SOCAM ltée c. Société du Parc Jean-Drapeau 2024 QCCS 604.

On method and proof, three divergences bite. First, no Quebec judgment names a delay-analysis methodology: no windows, no time impact analysis, no as-planned versus as-built, no collapsed as-built. What Quebec practice reports is a preference for the measured mile because it best demonstrates causation, acceptance of modified total cost exceptionally in Birdair inc. c. Danny's Construction Company Inc. 2013 QCCA 580, and treatment of total cost as least reliable. Do not import SCL or AACE terminology as though it carried authority here. Second, "réclamation globale" is not Quebec vocabulary and there is no Quebec analogue to Walter Lilly v Mackay, the debate runs instead on causation under art 1607 C.c.Q. and burden under art 2803 C.c.Q. Third, the critical path must be proved item by item: in the Compagnie de construction Édilbec litigation, of 156 change orders evidence was led on only three, and the schedule had not been updated as the change orders were issued. The sheer quantity of delaying events proves nothing. Which of the two Édilbec proceedings (2022 QCCA 1521 and 2024 QCCS 1737) is which is recorded as an unresolved conflict, the party ordering being reversed between them, verify before citing either.

The expert regime is the divergence most likely to catch a practitioner unprepared. Art 232 CCP provides that, jointly retained or not, the parties may not submit more than one expert report per discipline or matter unless the court authorises it by reason of the complexity or importance of the case. You get one delay expert. A planning expert plus a quantum expert plus a rebuttal expert is not available as of right. Leave is an argument, not an entitlement, and note precisely what art 232 is, a one-report-per-discipline cap, not a mandatory joint expert. Art 234 CCP lets the court order an expert report of its own motion, including on the delay analysis. Art 22 CCP makes the party-retained expert's mission to enlighten the court, and states that this mission overrides the parties' interests. A statutory duty stronger than the Ikarian Reefer formulation because it is codified and applies expressly to a party-retained expert. Art 18 CCP makes proportionality a live control on the means of proof. And art 241 CCP is reported to permit pre-trial rejection of an expert report, on application within ten days, for irregularity, serious error or bias, with reported grounds including insufficient description of methodology: recorded as unverified and single-source, and to be checked against the Code before it is relied on. Read together with the absence of any named methodology, the warning writes itself: a Quebec delay expert who does not set out its method explicitly is exposed on both flanks.

Layer: mixed, and the split runs down the middle of the table. The Code and Code of Civil Procedure rows: arts 1607, 1613, 1619, 1621 and 2803 C.c.Q., and arts 18, 22, 232 and 234 CCP, are primary-verified against LégisQuébec in French and official English. Art 241 CCP is the exception: it is recorded as unverified and single-source, and should be checked before use. The case rows rest on secondary law-firm commentary, and the two overhead percentages, 15% and 13.76%, are expressly recorded as unverified. Which Édilbec proceeding is which is an unresolved conflict.

Prompt payment, adjudication and security: three regimes and a security gap

A Quebec contractor can be running three different payment regimes at once, and the counter-intuitive one is federal: the federal Prompt Payment for Construction Work Act does apply in Quebec. Quebec is not a designated province. Meanwhile the Quebec public-work regime excludes the core of a delay claim by name, forbids lawyers in the room, and cannot grant time at all, and the hypothèque légale secures only the added value given to the immovable, which delay damages do not create.

The three regimes, stated plainly. First, Quebec public work runs on RLRQ c C-65.1, r 8.001, the Règlement sur les paiements et le règlement rapides des différends en matière de travaux de construction, Phase 1 in force 8 September 2025 for bâtiment work of $750,000 or more and génie civil work of $2.5M or more, Phase 2 from 8 September 2026 and Phase 3 from 8 September 2027. Second, federal work in Quebec runs on the Prompt Payment for Construction Work Act, SC 2019, c 29, s 387, in force 9 December 2023, because SOR/2023-270 designates only Ontario, Saskatchewan and Alberta. A province is carved out of the federal Act by designation, and Quebec has not been designated, so the federal Act governs there. Third, Quebec private work has no statutory regime at all: no prompt payment, no adjudication, nothing. That is the single largest structural difference from Ontario, Alberta and Saskatchewan, where private work is covered.

The comparator makes the gap visible. Under s 19 of O. Reg. 264/25, made under s 13.5 of Ontario's Construction Act and in force 1 January 2026, the adjudicable matters expressly include payment under the contract in respect of a change order whether approved or not, and three ancillary heads (scope of the work, a request for a change in the contract price, and a request for an extension of time) adjudicable where reasonably necessary to determine another adjudicable matter. So even in Ontario extension of time is ancillary rather than freestanding. In Quebec it is not available as relief at all.

What the Quebec public regime will and will not take is drawn with unusual precision, and the section numbers are a known trap. The exclusion is s 33, and the covered disputes are at s 34, s 32 was the draft numbering and should not be cited. Section 33 excludes any monetary claim to compensate for loss of profit, loss of productivity or loss of a business opportunity suffered because of a change relating to the scope of the work or to the conditions of its performance. That is the core of a delay and disruption claim, carved out by name. Prolongation cost (extended site overhead) is not on the closed list of three, and is arguably within jurisdiction under s 34. What is squarely in is the money consequence of a change, the exigibility of sums, and the validity of a deduction, including a delay-penalty deduction. No provision empowers the tiers décideur (the third-party decision-maker) to grant an extension of time, so extension entitlement can be litigated only incidentally, as the reason a penalty deduction was or was not justified. Add art 55 of r 8.001, under which the parties may not be represented by lawyers, including in-house counsel, together with the proportionality duty and the 50-day clock, and the design intent is unmistakable: Quebec built a cash-flow forum, not a delay-claims forum.

The security position completes the picture, and it is worse than a lien practitioner will expect. Under arts 2726 and 2952 C.c.Q. the hypothèque légale de la construction charges only the immovable and exists only in favour of the plus-value (the added value given to it) ranking ahead of all other hypothecs, but only for that added value. Art 2727 C.c.Q. gives 30 days from fin des travaux to publish a notice and serve it on the owner, and six months from the end of the work to publish an action or register a prior notice of exercise. Delay damages (prolongation, disruption, loss of productivity, recovery of penalties) add no plus-value to the immovable and are therefore, on the ordinary reading of arts 2726 and 2952, unsecured. State the limit of that proposition honestly: no Quebec judgment holding in terms that delay damages are unsecured by the legal hypothec was located. The plus-value limitation is primary-verified. The consequence for delay damages is an inference from it. A contractor with a large delay claim and a small unpaid measured-work balance therefore holds little security over the part of its claim that matters most, which is precisely why the s 33 exclusion of profit and productivity claims bites so hard.

Layer: mixed, and both halves are primary. The regulation and statute rows rest on primary instruments: RLRQ c C-65.1, r 8.001 ss 33, 34 and 55, the federal Prompt Payment for Construction Work Act and SOR/2023-270, and Ontario's O. Reg. 264/25 s 19. The Code rows: arts 2111, 2122, 2726, 2727 and 2952 C.c.Q., are primary-verified against LégisQuébec in French and official English. No case commentary is relied on in this table. The one inferential step is expressly marked: that delay damages fall outside the plus-value is a reading of arts 2726 and 2952, and no Quebec judgment holding it in terms was located.

Five things to fix in a common-law draft before it is used in Quebec

Five edits convert a common-law Canadian construction contract from actively dangerous to merely imperfect in Quebec. Each addresses a provision that either assumes a doctrine Quebec does not have, or is ineffective against a public-order rule in the Code civil du Québec. Work through them before the contract is executed, because three of the five cannot be cured afterwards.

Two further edits are worth making even though the source list stops at five. Draft the delay penalty as being for delay alone, because art 1622 C.c.Q. otherwise puts the owner to an election between performance and the penalty. And bring the claim procedure into the signed contract rather than leaving it in an incorporated general-conditions booklet, because art 1435 C.c.Q. nullifies an external clause not expressly brought to the adhering party's attention at formation. An argument that became squarely available after Terrassement St-Louis, 2025 QCCA 900, and one that no Quebec construction case has yet been located applying to a claim-procedure time bar.
