Executive Summary: Key Legal and Evidentiary Issues

• Classification of the nine-hour flight delay as a situation outside the carrier’s control and/or necessary for safety under the RPPA and the Montreal Convention
• Assessment of whether Sunwing Airlines met its burden to prove the safety-related diversion and subsequent “knock-on” delay as a complete answer to compensation claims
• Interpretation of Sunwing’s email “difficultés opérationnelles” notifications and whether they amounted to incomplete disclosure or an extra-judicial admission of carrier fault
• Evaluation of passengers’ entitlement to statutory delay compensation, moral damages, and punitive damages in light of federal air passenger protection standards
• Scrutiny of Vacances Sunwing’s terms and conditions, including unilateral schedule-change and limitation-of-liability clauses, against Québec consumer protection and civil code rules
• Determination that the claimed contractual and statutory breaches were not established on the evidence, leading to dismissal of all monetary claims and awarding of costs against the passengers

Factual background

Pierre Pratte and Line Caron booked a Sunwing vacation package from Montréal to Cancún for the period of 18 April to 25 April 2024, under booking number 135519553. Their outbound flight from Montréal to Cancún on 18 April 2024 was initially scheduled to depart at 9:30 a.m. but ultimately left at approximately 9:46 p.m., resulting in a delay of more than nine hours. They arrived in Cancún around 1:00 a.m. local time, passed through customs, travelled to their hotel, and went to bed at approximately 3:00 a.m. (4:00 a.m. EDT), which significantly disrupted the start of their vacation. The passengers received three email alerts from Sunwing on 18 April: at 1:34 a.m., 4:03 p.m. and 9:33 p.m., each advising of schedule changes and referring to “difficultés opérationnelles concernant la flotte attribuée à votre vol.” Based on this wording, the passengers understood the delay to be attributable to Sunwing’s own operations, such as aircraft or crew shortages, and they later advanced compensation claims on that basis.

Passengers’ claims and alleged damages

In their amended small claims action, Mr. Pratte and Ms. Caron sought a total of $14,000 against Vacances Sunwing Inc., as tour wholesaler, and Sunwing Airlines Inc., as air carrier. They claimed $1,000 each as statutory compensation for flight delay, $1,000 each for troubles, inconvenience and loss of enjoyment of their vacation, and $10,000 in punitive damages, ultimately directed against Vacances Sunwing alone. They argued that they had lost an entire portion of their vacation: the late afternoon and evening of 18 April, as well as the morning and early afternoon of 19 April due to exhaustion from the overnight arrival. They stressed their ages (57 and 68) and testified that recovery from the disruption was more difficult than it would be for younger travellers. Ms. Caron described the trip as a “cauchemar” and said it took her time to recover. In their demand letter and argument, the passengers interpreted the Air Passenger Protection Regulations (Règlement sur la protection des passagers aériens – RPPA) as granting a minimum $1,000 delay compensation each, with the possibility of a higher amount, since the regulation referred to an “indemnité minimale.” They therefore claimed $1,500 each as delay compensation and $1,000 each for non-pecuniary troubles and inconveniences, on top of the $10,000 punitive damages request.

Defences raised by Vacances Sunwing and Sunwing Airlines

Vacances Sunwing and Sunwing Airlines filed a joint defence. They argued that the passengers were at all times bound by Vacances Sunwing’s terms and conditions of purchase, including clauses permitting schedule changes and limiting liability. Sunwing Airlines relied squarely on the RPPA and its classification framework, as administered and interpreted by the Canadian Transportation Agency (Office des transports du Canada – OTC). It pleaded that the delay resulted from circumstances outside the carrier’s control and/or necessary for safety reasons and therefore did not trigger statutory delay compensation. The defendants also relied on the Montreal Convention, arguing that any contractual or extra-contractual claim for damages was barred because the carrier had taken all measures reasonably required to avoid the harm caused by the delay.

Evidence of the inbound flight disruption and safety diversion

At trial, Sunwing’s claims specialist, Sophie Brouillette, testified about the operational chain of events. She confirmed that the Montréal–Cancún flight of 18 April 2024, on which the plaintiffs were booked, was delayed by more than nine hours. She explained that the aircraft assigned to operate this route was the same aircraft used on flight WG 7393, flying from Jamaica to Montréal. During WG 7393, an unruly passenger incident arose at level 3 severity. The passenger reportedly suffered a mental health crisis and engaged in violent, threatening and disorderly behaviour on board. Attempts by the crew to de-escalate the situation failed, and the passenger was assessed as a threat to the safety and security of the aircraft, other passengers and crew. The captain decided to divert the aircraft to Miami (MIA) so that local authorities could remove the passenger. Once in Miami, authorities escorted the passenger off the aircraft, and a baggage removal process was carried out to ensure that the passenger’s checked baggage did not remain on board. Due to the overweight nature of the diversion landing, the aircraft required an additional inspection before it could be cleared to depart. Because Miami is not a regular Sunwing destination, finding an approved maintenance technician proved difficult, resulting in the aircraft remaining overnight in Miami. The crew of WG 7393 rested in Miami before repositioning the aircraft back to Montréal. To recover the schedule as quickly as possible, Sunwing redeployed another aircraft from the St-Martin – Montréal route (and, in parallel, used aircraft from Toronto) and adjusted operations to comply with Montréal arrival curfew rules. Additional minor technical issues, such as an autopilot reset, were also dealt with before departure. Throughout this period, Sunwing issued delay notifications, flight alerts and airport announcements, and it provided meal vouchers, taxi vouchers and hotel accommodation for out-of-town passengers, as required by the RPPA standards of treatment for disruptions outside carrier control.

Regulatory and legal framework governing the delay

The court framed the dispute within three main legal instruments: the Canadian Loi sur le transport aérien and its incorporation of the Montreal Convention, the RPPA, and the Loi sur les transports au Canada as amended in 2023. Under article 19 of the Montreal Convention, an air carrier is liable for damage caused by delay unless it proves that it took all measures that could reasonably be required to avoid the damage or that it was impossible to take such measures. This establishes a rebuttable presumption of liability, placing the burden on the carrier. The 2023 amendments to the Loi sur les transports au Canada reinforce that, for domestic air passenger rights purposes, the carrier must demonstrate that the delay was due to a situation beyond its control or necessary for safety. When a delay is genuinely outside the carrier’s control and required on safety grounds, the RPPA classifies it as non-compensable, although standards of treatment (such as meals and accommodation) still apply.

Disputed meaning of the “operational difficulties” notifications

The passengers argued that the three email alerts they received on 18 April, each referring to “difficultés opérationnelles concernant la flotte,” amounted to an extra-judicial admission that the delay was caused by internal operational failures (such as lack of aircraft or crew) rather than by a chain reaction from an earlier safety-related diversion. They also alleged that Sunwing breached its regulatory duty to give complete and detailed reasons for the delay in its communications, contrary to the RPPA and the Canadian Transportation Agency’s guidance documents on delays, cancellations and communication with passengers. In their view, had Sunwing fully disclosed the inbound diversion, they would have had clearer grounds to contest the company’s subsequent refusal of delay compensation. The court acknowledged that if the alert emails were incomplete, this could be a regulatory shortcoming. However, it held that this communication point had to be assessed together with the full evidentiary record, including the detailed operational reports and Sunwing’s formal written response to the demand letter, which spelled out the unruly passenger incident, the diversion to Miami, the maintenance inspection, crew rest requirements and subsequent recovery actions. The judge concluded that, even if the emails were not fully descriptive, this did not transform a safety-driven diversion into a discretionary operational delay attributable to the carrier, nor did it amount to a binding admission of liability.

Challenges to Sunwing’s terms and conditions and limitation clauses

Beyond the delay-compensation dispute, the plaintiffs attacked Vacances Sunwing’s standard booking terms. They targeted clauses permitting unilateral modification of flight schedules and clauses purporting to exclude or limit liability, invoking articles 10 and 11.2 of the Québec Loi sur la protection du consommateur and articles 1435 and 1474 of the Code civil du Québec. They argued that these provisions were abusive or null, and that a tour wholesaler cannot escape responsibility for troubles, inconveniences and loss of enjoyment arising from a significantly delayed departure. The court ultimately found it unnecessary to decide the full validity or effect of these clauses in the abstract. It noted that the “reserve of responsibility” clause had not actually been applied to bar a valid recourse in this case, and that, in any event, Québec jurisprudence permits courts to disregard such clauses when they would improperly block an otherwise legitimate claim. Because the plaintiffs’ substantive claim failed on the facts and the governing federal air transport law, the court did not need to invalidate or apply the clauses to resolve the dispute.

Application of the RPPA and the Montreal Convention to the facts

On the core liability question, the judge held that Sunwing Airlines had discharged its burden of proof. The detailed incident report, corroborated by Ms. Brouillette’s testimony and the written response to the demand letter, showed that the original disruption was caused by an unruly passenger who posed a safety and security risk, leading to a diversion to Miami and subsequent knock-on delays to the entire rotation. This chain of events was treated as a “knock-on delay” expressly contemplated in the RPPA guidance for situations outside the carrier’s control, where the delay flows from necessary safety actions on a previous segment. The court accepted that Sunwing had taken all reasonable measures to mitigate the delay, including redeploying other aircraft, complying with curfew rules, resolving technical issues, and providing vouchers and accommodation, and that no faster recovery was realistically possible. As a result, the disruption was characterized as outside the carrier’s control and necessary for safety, meaning that no statutory delay compensation was owed under the RPPA. For the same reasons, the Montreal Convention’s presumption of liability for delay was rebutted: the carrier had proven that it took all measures that could reasonably be required and that the residual delay could not have been further reduced by any feasible means.

Treatment of moral and punitive damages claims

Because the delay fell into the non-compensable category under the RPPA and the Montreal Convention, the court held that it could not award the $1,000 per person sought for troubles and inconveniences or the $10,000 in punitive damages. The judge emphasized that punitive damages require a separate legal basis and egregious behaviour; the facts here did not support such a remedy. Although the passengers experienced a disturbed start to their vacation and prepared their case thoroughly, including producing authorities and a written pleading plan unusual for small claims, the law required more than inconvenience and dissatisfaction to impose liability where safety-driven disruptions were properly documented and addressed.

Outcome and allocation of costs

In conclusion, the Court of Québec, Small Claims Division, found that the evidence convincingly established that the nine-hour delay stemmed from an unruly passenger incident and a safety-motivated diversion on the inbound flight, a situation outside Sunwing Airlines’ control and necessary for safety. The plaintiffs did not succeed in recharacterizing the delay as an internal operational failure nor in demonstrating any breach of applicable air passenger protection standards that would give rise to compensation. All heads of claim—statutory delay compensation, moral damages for troubles and inconveniences, and punitive damages—were therefore dismissed. The defendants, Vacances Sunwing Inc. and Sunwing Airlines Inc., were the successful parties, and the only monetary order made by the court was to condemn the plaintiffs, Mr. Pratte and Ms. Caron, to pay $364 in legal costs in favour of the defendants.
