Executive Summary: Key Legal and Evidentiary Issues

• Allocation of responsibility for significant construction delays in a multi-phase residential infrastructure project and whether the contractor could recover increased costs despite a fixed-price contract.
• Validity and enforceability of contractual penalty clauses for late completion, including whether the owner and its engineer applied them coherently and in good faith.
• Proof and quantification of additional costs claimed by the contractor due to owner-ordered suspensions, regulatory approvals, and project rescheduling.
• Legitimacy of the developer’s claim for additional site-supervision fees where the contracts did not clearly support the method and rate of calculation.
• Lawfulness of a construction legal hypothec (builder’s lien) and pre-notice of exercise registered against the property, and whether they could be maintained as security for the contractor’s claim.
• Impact of extensive change orders and altered project sequencing on the original contract structure and on the owner’s ability to rely on contractual penalty mechanisms.

Factual background and parties

The dispute arises from a large residential subdivision and infrastructure development known as the Grand Boisé project in the City of La Prairie, at the intersection of Highway 30 and Chemin Saint-Jean (Route 104). The works were divided into four phases, each governed by a separate written contract. The project involved substantial civil works: roads, water and sewer networks, lighting, pumping stations, a large stormwater retention basin and a noise barrier.
175784 Canada inc. (Bricon) is a civil engineering contractor acting as general contractor. Grand Boisé de La Prairie inc. (GBL) is the real estate developer and owner of the project. Two related corporations, 9255-2504 Québec inc. and 142550 Canada inc., were also involved, with 142550 owning the immovable that became charged by Bricon’s legal hypothec. The developer and its related companies retained Bricon for all four phases after initial public tendering by the City for Phase I.
The consulting engineering firm Groupe-conseil Génipur inc. (Génipur) acted as the owner’s representative and site supervisor. Génipur prepared the tender documents, oversaw the works, issued change orders and certified payments and provisional and final acceptances.

Project evolution and contracts

Phase I followed a municipal call for tenders for the construction of local streets, underground services, pumping stations, the retention basin and a noise berm. The City awarded the contract to Bricon, and GBL as developer participated through Génipur. The submission form fixed strict time limits: 100 working days from July 2014 for most works and 25 working days the following year for remaining items. Despite delays, Génipur ultimately issued a final acceptance certificate in October 2017 and recommended full and final payment, which was made in December 2017.
While Phase I was ongoing, GBL, through Génipur, directly invited Bricon (without a new public tender) to bid on Phases II-III and later Phase IV. Each subsequent contract fixed detailed completion deadlines expressed in working days from an “order to begin work.” The contracts incorporated “clauses administratives générales” and “clauses administratives particulières” providing for:

• a fixed-price (forfaitaire) structure;
• an obligation to carry out the works continuously from the authorization to start;
• no entitlement to price increases simply because the work proved more expensive;
• a schedule-extension mechanism where variations or uncontrollable events warranted more time; and
• penalty clauses of CAD 1,500 per working day of delay, plus, in the general clauses, compensation for actual supervision costs when delay was attributable to the contractor.

Suspensions, regulatory approvals and change orders

Shortly after the Phase II-III contract began, the parties anticipated a new commercial street, Rue Vice-Roi. Génipur advised Bricon that the street alignment was under review by the City. Bricon prepared a schedule for the planned works, initially excluding Rue Vice-Roi.
In April 2016, GBL issued a change notice (AC-10) for the extension of Rue Vice-Roi and asked Bricon for a price. Bricon submitted a quotation around CAD 1.16 million, which was negotiated down to approximately CAD 1.149 million to fit the owner’s budget. Shortly thereafter, in May 2016, Génipur ordered Bricon to stop work when it emerged that GBL had not obtained necessary environmental certificates from the provincial Ministry of the Environment for the additional sanitary, storm and water networks and for habitat protection of the Western chorus frog.
Regulatory approval came only in late August 2016. By then, Bricon’s crews were deployed on other projects, and it lacked capacity to restart immediately. Work resumed in September but was again halted when GBL and the City agreed that the City, not the developer, would bear the cost of the street extension; adoption of a municipal borrowing by-law was required before work could lawfully proceed. The by-law was only adopted and communicated in May 2017, roughly a year after the originally planned timing.
These suspensions occurred through no fault of Bricon. The parties eventually formalized the Vice-Roi extension through a final change order (OC-10) in July 2017, fixing a reduced lump sum of CAD 1,005,467.61 plus taxes and extending the contractual time limit by 25 working days. Finishing works associated with OC-10 continued into 2019.
Phase IV covered additional streets and an enlargement of the retention basin. Bricon again obtained the contract. During the 2016–2018 period, works shifted in and out depending on weather, municipal concerns about lowering water levels in winter, and the sequencing of utilities. Génipur at one point explicitly advised that certain basin works could be performed after spring thaw because they did not affect builders or the City, leading to further decoupling of the original timelines from actual site activities.

Unpaid balances and contractor’s monetary claim

By the time the later phases were substantially completed, Bricon claimed that significant contract balances remained unpaid: approximately CAD 489,151.66 for Phase II-III and CAD 251,221.77 for Phase IV, for a total of CAD 740,343.43. These sums corresponded to work completed and certified but withheld by the developer.
Bricon also claimed CAD 89,392.15 (taxes included) for increased costs of labour, materials, equipment, insurance and administrative overhead associated with the long postponement of the Rue Vice-Roi works. It adduced detailed testimony and documentary support from its senior project manager, engineer Judith Aubry, as well as invoices, sub-contract quotations and receipts. She explained that the long regulatory and financing delay meant that negotiated unit prices expired and previously engaged subcontractors refused to perform at the original rates. For example, original paving subcontractor Pavage Maska declined to execute delayed curb and sidewalk work in 2018; Bricon was forced to retain another firm, Eurovia, at higher prices. Bricon also had to duplicate mobilization, surveying and temporary works such as cofferdams (batardeaux) and to extend its site insurance and project management efforts.

Developer’s defence, penalties and surveillance fees

In response, GBL and the related companies did not dispute that the unpaid balances for work done were arithmetically owing. They contended, however, that they were entitled to offset these sums with contractual penalties for delay and additional supervision fees. Their reconventional claim sought about CAD 742,736.54 (taxes included) in penalties and “frais de surveillance additionnelle” charged by Génipur.
The owner’s theory rested on the penalty clauses in the general and particular administrative conditions. Those clauses required the contractor to complete works within a specified period measured in working days and provided, among other things, that if the contractor, “by its fault,” failed to do so, it would owe:

• all wages, salaries and travel expenses paid by the owner for persons supervising the works during the period of delay; and
• fixed daily liquidated damages of CAD 1,500 per working day of delay, plus an equal amount for statutory holidays on which work was allowed.
  The owner and Génipur compiled several spreadsheets (notably exhibit D-6 and later D-65) that attempted to convert daily site-supervision records into a count of “late days.” Initially, they equated “jours surveillés” (days on which a supervisor was present) with days of contractor work in excess of the original schedule. Later, particularly from May 2018 onward, they modified their methodology to count not only actual work days but also days when, in their view, Bricon “should have been” on site, even including weekend days, and they began to claim both penalties and a separate per-day surveillance fee of CAD 750.
  Bricon argued that this entire framework was incoherent, contrary to the contract language and abusive in light of how the project had been managed: numerous change orders (roughly one hundred), overlapping phases, owner-ordered suspensions and late regulatory and financing approvals. It stressed that for over two years of collaboration no one raised the possibility of penalties; Génipur representatives even reassured Bricon that time limits were not a concern, while the developer continued to award further phases without new tenders.

Legal framework: fixed-price contracts and increased costs

On the question of increased costs, the Court relied on article 2109 of the Civil Code of Québec (C.c.Q.), which provides that in a lump-sum (forfaitaire) contract the client must pay the agreed price and generally cannot claim a reduction simply because the work cost less than expected, while the contractor cannot claim an increase merely because it cost more or was more onerous. Exceptionally, additional compensation may be available where the client has failed in its duty to inform or where unforeseen circumstances outside the contractor’s risk allocation fundamentally change the situation.
The Court drew on leading case law such as Coffrage Alliance ltée v. Procureure générale du Québec and decisions on the owner’s obligation to inform and the corresponding duty of the contractor to investigate site conditions. In the construction context, courts recognize that while the contractor usually bears the risk of normal unforeseen difficulties, it is entitled to rely on accurate information and to expect that the owner will not unreasonably shift to it the burden of regulatory or financing delays that the owner itself created or controlled.

Legal framework: penalty clauses, good faith and coherence

Regarding penalties, the Court emphasized that contractual obligations must be performed fully and without delay (art. 1590 C.c.Q.), and that an obligation to meet a time limit in a construction contract is normally an obligation of result. Absent force majeure or interference by the owner, the contractor faces a presumption of liability if completion dates are missed.
At the same time, article 1623 C.c.Q. allows courts to reduce or decline to enforce penalty clauses that are abusive or where partial performance has benefited the creditor. Overarching all of this is the duty of good faith and loyalty in contractual performance (arts. 6, 7 and 1375 C.c.Q.), which Québec jurisprudence has developed into a specific “duty of coherence.” A party may not act in a manner that contradicts the legitimate expectations it has itself created in the other contracting party by words or conduct.
The Court drew from authorities such as Hydro-Québec c. Construction Kiewit, Inter-Cité Construction ltée c. Québec and Services Ricova inc. c. Ville de Montréal, where owners were prevented from relying mechanically on onerous clauses when their own behavior had led contractors to reasonably believe that strict enforcement would not occur or where they had altered, in practice, the way clauses were applied.
The judgment also relied on case law about change orders and contract modification, including Birtz Bastien Beaudoin Laforest Architectes c. CHUM. There, the Court held that unilateral modifications exceeding roughly 15–20% of the original scope can “dénaturer” a contract, justifying judicial intervention particularly in contracts of adhesion like public construction contracts awarded after a call for tenders.

Court’s analysis on increased costs

On the evidence, the Court found that the delays and suspensions affecting the Rue Vice-Roi extension stemmed from the developer’s and City’s need to obtain environmental approval and a borrowing by-law, not from any default by Bricon. The sequence of events made clear that Bricon had originally priced the work for performance in 2016; when approvals and funding were not forthcoming, the work slipped by over a year.
The Court rejected the owner’s argument that Bricon had first raised the increased-cost claim only when litigation began. Correspondence showed that Bricon had warned Génipur as early as July 2016 that materials had been ordered and delivered, and later, in July 2018, that increased prices for paving, concrete and topsoil (tourbe) due to the postponement would be passed on. The Court accepted Aubry’s detailed explanation of the actual cost escalations and noted that Bricon had supported its claim with documentary proof and proof of payment to subcontractors.
Although the general conditions contained a clause on temporary work stoppages stating that the contractor could not claim against the owner in the event of an “arrêt temporaire des travaux,” the Court held that a literal application of that clause in these circumstances would be unreasonable and inconsistent with good faith. Bricon had priced its tender based on a reasonable, continuous schedule; it could not have anticipated multiple prolonged suspensions triggered by the owner’s failure to secure regulatory approvals and financing. The Court concluded that the developer should bear the financial consequences of the resulting inflationary increase in labour and material costs and the additional general expenses.
Accordingly, Bricon was awarded the full amount claimed for increased costs, CAD 89,392.15 (taxes included), in addition to the undisputed unpaid contract balances.

Court’s analysis on penalties for delay

Turning to penalties, the Court first noted that the contracts were clearly contracts of adhesion drafted by or for the developer and city, using standard municipal clauses that contractors could not negotiate. Bricon’s only real choice was to bid on those terms or abstain.
Crucially, the developer and Génipur were unable to identify with precision the dates on which Bricon allegedly fell into delay, or the exact periods that should count as late. Their own pleadings admitted that their main spreadsheet (D-6) did not isolate precise days of delay; it simply compared “days supervised” to “days stipulated” in the contracts. In their written argument, they even characterized the exercise of determining exact days of delay as “arduous” because of the duration of the project and overlapping phases.
The Court held that, without clear proof of when and how contractual time limits were exceeded, the owner could not meet its burden for enforcing the penalty clauses. The improvised conversion of supervision days into delay days, and the later shift to counting hypothetical days when Bricon “should have been” working, had no basis in the contract language and amounted to a unilateral re-write of the penalty mechanism.
The Court further found a breach of the duty of coherence. For more than two years—from 2014 through late 2016—no one at GBL or Génipur raised the issue of penalties. On the contrary, Bricon was repeatedly told that delays were not a problem, and GBL awarded it additional phases without going back to tender. In early 2015, when Bricon asked for time extensions in connection with various change orders, a Génipur representative reassured Aubry that the 2014 works had been done within the applicable delay and that she need not worry about deadlines.
Only in December 2016 did Génipur suddenly raise the idea of penalties by comparing total supervision days with the original contractual durations and claiming tens of days of delay. Even then, discussions continued and in December 2017, when Génipur processed the final payment for Phase I, it applied penalties for only four days of delay (CAD 6,000). The Court interpreted this as an express or at least clear renunciation of any right to claim additional penalties for Phase I, particularly as no reservation or protest was noted on the payment documents.
By February 2018, Génipur recalculated penalties at 55.25 days across the phases, still using the “days supervised” method. During a meeting that month, according to Aubry’s uncontradicted testimony, Génipur acknowledged that the penalties were effectively being used to cover its own loss on surveillance services that it had underpriced in its original proposal to GBL, rather than to compensate GBL for genuine project damages. This was confirmed by Aubry’s contemporaneous correspondence to GBL’s finance director, in which she accused Génipur of trying to make Bricon absorb its mis-estimation of supervision costs.
In May 2018, Génipur changed its approach again, adding “frais de surveillance additionnelle” of CAD 750 per day on top of the existing penalty of CAD 1,500 per day, then issuing a new spreadsheet seeking 296.25 days of penalties—almost a five-fold increase—with no intervening change in the project’s factual status. The Court described this escalation as absurd and unreasonable.
The Court concluded that:

• the penalty clauses had been applied in a manner contrary to their wording;
• the developer and its engineer had modified, without Bricon’s consent, the contractual mechanism by tying penalties to surveillance days and later to hypothetical work days;
• the contracts themselves had been substantially transformed by an accumulation of change orders (e.g., additional days representing 53% of the original duration for Phase I, 79% for Phase II-III and 27.66% for Phase IV), effectively altering the original balance of obligations; and
• the owner had failed to prove any concrete prejudice from the alleged delays, such as inability to sell lots or transfer streets to the City, reputational harm or financial loss.
  In light of the absence of reliable proof of delay, the incoherent and evolving methodology, the extensive change-order-driven transformation of the project and the lack of demonstrated prejudice, the Court held the penalty clauses inapplicable and, to the extent relied on by the owner, abusive. The reconventional claim for penalties was therefore rejected in full.

Court’s analysis on additional surveillance fees

The claim for standalone additional surveillance fees of approximately CAD 206,338 was also dismissed. The Court observed that the contracts allowed the owner, in case of contractor-caused delay, to claim reimbursement of “treatments, salaries and travel expenses” actually paid to those supervising the works during the period of delay. Yet the owner had expressly admitted in its pleadings that there was no clearly delimited “period of delay.”
Moreover, Génipur’s claimed rate of more than CAD 3,800 per “surveillance day” lacked contractual support or detailed breakdowns showing hours worked or tasks performed. There were no daily reports for the alleged additional surveillance in 2018, and Génipur attempted to stretch the concept of “surveillance de chantier” to include back-office administrative follow-up, which the Court rejected as an unreasonable interpretation of the contract language.
Given the absence of proof of qualifying delay periods, the lack of detailed time records and the inflated, unexplained rate, the Court considered the surveillance claim “démesurée et abusive” and dismissed it entirely.

Legal hypothec, pre-notice and enforcement on the immovable

Facing non-payment, Bricon registered a legal hypothec of construction on the immovable owned by 142550 Canada inc. on 8 January 2019 for CAD 310,224.23 and later published a pre-notice of exercise of its hypothecary right. In its action, Bricon asked the Court to declare both registrations valid and to authorize hypothecary remedies, including forced surrender and judicial sale of the property.
The defendants did not contest the formal validity of the hypothec or pre-notice; they simply sought cancellation in the event their penalty and surveillance counterclaim exceeded Bricon’s claim. Because the Court rejected the owner’s counterclaim and confirmed that substantial sums remained owing to Bricon, it upheld the hypothec and pre-notice.
The judgment orders 142550 Canada inc. to surrender the property within 48 hours of service of the judgment, failing which it may be expelled by bailiff. It authorizes sale under judicial control, appoints designated bailiffs from Paquette & Associés to conduct a private sale, prepare the collocation scheme and distribute sale proceeds, and fixes a minimum sale price equal to the hypothec amount of CAD 310,224.23. The sale will be “without legal warranty” at the purchaser’s risk, and the judgment sets out detailed conditions regarding deposits, allocation of taxes and fees, and the possibility for Bricon itself to become purchaser and offset the price against its secured claim.

Outcome and monetary award

In the result, the Superior Court of Québec fully allowed Bricon’s modified originating application, dismissed the developer’s amended defence and counterclaim, confirmed the validity of Bricon’s legal construction hypothec and pre-notice and ordered judicial sale of the encumbered immovable under court control. The Court condemned the developer entities to pay Bricon a principal sum of CAD 829,765.58 (taxes included), representing unpaid contract balances and increased costs, together with legal interest and the additional indemnity from 30 September 2018, plus costs of justice including the expenses of the judicial sale. Bricon is thus the successful party; while the exact ultimate total including accrued interest, additional indemnity and sale-related costs cannot be calculated from the judgment alone, the principal amount awarded in its favour is clearly set at CAD 829,765.58.
