What happens when Porter cancels flights?
Porter is subject to the same three-category system as other airlines under the Air Passenger Protection Regulations (APPR). The APPR obligations are also incorporated into Porter's tariffs.
What Porter owes you depends first on why the flight was delayed or cancelled.
Within Porter's control. This category can include ordinary commercial and operational decisions, staffing and scheduling issues, and other matters for which Porter is responsible. Where the statutory conditions are met, Porter must provide information, standards of treatment, alternate travel or an applicable refund, and standardized compensation.
For a large carrier such as Porter, section 17 requires Porter first to provide a confirmed reservation on its own or a commercial partner's next available flight departing within nine hours of the departure time on your original ticket. If it cannot, it must provide the next available flight operated by any carrier on a reasonable route departing within 48 hours. If that is still not possible, transportation through another nearby airport may be required.
A refund is not automatically an immediate alternative to rebooking. For a within-control disruption, section 17 provides a refund where the alternate arrangements offered do not accommodate your travel needs.
Within Porter's control but required for safety. This can include an unexpected mechanical malfunction that reduces passenger safety or a safety decision made by the pilot or under the airline's safety management system. Standardized section 19 compensation does not apply, but standards of treatment and section 17 rebooking or refund rights can still apply.
Scheduled maintenance undertaken in compliance with legal requirements is expressly excluded from the APPR definition of a disruption "required for safety purposes."
Outside Porter's control. Section 10 includes qualifying weather conditions, air traffic control instructions, airport-operation issues, security threats, medical emergencies, collisions with wildlife, certain labour disruptions and other listed events.
For these disruptions, standardized compensation and section 14 standards of treatment generally do not apply. Porter must nevertheless provide alternate travel under section 18.
It must first provide a confirmed reservation on its own flight or that of a commercial partner departing within 48 hours of the original departure time. If it cannot do that, further rights arise. Because Porter is a large carrier, you can choose further transportation on the next available flight operated by any carrier on a reasonable route, or choose the applicable refund.
Do not rely only on the category name Porter gives you. Preserve the actual reason it provides and any later explanation. If the explanation changes, keep every version.
Porter is a large airline under the APPR: $400 to $1,000
The APPR defines a large carrier as one that transported at least two million passengers worldwide in each of the two preceding calendar years.
Porter's tariffs state that Porter was a small carrier through December 31, 2024 and became a large carrier on January 1, 2025.
That distinction matters. For qualifying Porter flights from January 1, 2025 onward, the large-carrier compensation and rebooking rules apply.
For a delay or cancellation within Porter's control and not required for safety, section 19 provides:
| Arrival delay at your destination | Amount per passenger |
|---|---|
| 3 hours to under 6 hours | $400 |
| 6 hours to under 9 hours | $700 |
| 9 hours or more | $1,000 |
The delay is measured by how late you arrive at the destination shown on your original ticket. Under the APPR, arrival occurs when at least one aircraft door opens after landing to allow passengers to leave.
If the disruption otherwise qualifies under section 12 and your ticket is refunded under section 17(2), section 19(2) provides compensation of $400. Taking a refund does not automatically create that entitlement. The underlying disruption must still have been within Porter's control, not required for safety, and otherwise satisfy the APPR compensation requirements.
Denied boarding is governed separately. Where qualifying involuntary denied boarding is within Porter's control and not required for safety, compensation is $900 if you arrive less than six hours late, $1,800 for six to under nine hours, and $2,400 for nine hours or more. The large-versus-small distinction does not affect those amounts.
Compensation is assessed per passenger. Porter's current online compensation process handles claims per passenger and per journey.
Porter's status as a large carrier is also important for rebooking.
For a within-control or safety-related disruption, if Porter cannot provide its own or a commercial partner's flight departing within nine hours, it must look to any airline for a flight departing within 48 hours.
For an outside-control disruption, Porter first gets 48 hours to find its own or a commercial partner's flight. Only if it cannot meet that requirement do the further large-carrier rebooking rights on another airline arise.
Those are different rules, and the distinction matters if Porter offers you only its own much later flight.
How to file a claim with Porter
Porter provides an online compensation eligibility and claim process for delayed and cancelled flights. Its current system asks for the passenger's booking information and processes compensation claims per passenger and per journey.
Use the online process if it is helpful, but preserve what you submit.
For the clearest evidentiary record, we recommend making your compensation request in writing by registered mail or another trackable delivery method to Porter's published Customer Relations address. Keep an exact copy of the letter, every attachment, the tracking record and proof of delivery.
Your claim should identify the passenger, booking reference, flight number, travel date, original arrival time, actual arrival time, the reason Porter gave for the disruption, the APPR provision relied on and the amount claimed.
You can also submit through Porter's online system. If you do, save screenshots or a PDF of the completed submission, the confirmation number and every response Porter sends.
For section 19 delay or cancellation compensation, the request must be made before the first anniversary of the disruption.
Porter then has 30 days after receiving the compensation request to either provide the compensation or explain why it is not payable.
Porter also maintains a separate process for out-of-pocket expense claims. If you paid for meals, accommodation or transportation because Porter failed to provide treatment required by the APPR, keep itemized receipts and preserve a complete copy of the expense submission.
Do not confuse an expense claim with the standardized compensation claim. They involve different entitlements and should be documented separately.
What Porter must give you during the delay
Where the delay or cancellation is within Porter's control, including where it is required for safety, and you were informed less than 12 hours before the departure time on your original ticket, section 14 can require standards of treatment.
After you have waited two hours beyond the original scheduled departure time, Porter must provide reasonable food and drink and access to a means of communication.
The hotel obligation is separate from the two-hour rule.
If Porter expects that you will have to wait overnight for your original flight or for alternate transportation, it must provide reasonable hotel or comparable accommodation and transportation between the airport and the accommodation.
Porter may limit or refuse the treatment if providing it would further delay you.
If Porter fails to provide treatment that the APPR requires and you incur reasonable expenses yourself, keep itemized receipts and submit them for reimbursement.
Porter publishes its own expense-reimbursement guidance, including suggested meal amounts. Those published guidelines do not necessarily define the full extent of the statutory obligation. Section 14 requires food and drink in reasonable quantities, taking into account the length of the wait, time of day and passenger's location.
Porter must also provide information about the disruption under section 13, including the reason, potential compensation, standards of treatment and available recourse.
During a delay, Porter must generally provide status updates every 30 minutes until a new departure time is set or alternate travel arrangements are made. New information must be communicated as soon as feasible.
For an outside-control disruption such as qualifying severe weather, the APPR does not require Porter to provide section 14 meals or accommodation. Travel insurance or credit-card coverage may provide separate protection.
When Porter denies your claim
Start with the reason Porter actually gives.
Keep the refusal, together with every earlier explanation from the airport, email, text message or app. If the stated cause changes, preserve all versions.
"Outside our control." Ask Porter to identify the particular event it says caused your disruption, when it occurred, and how it affected your flight.
If Porter relies on an earlier outside-control event, section 10(2) requires the later disruption to be directly attributable to that earlier event. Porter must also have taken all reasonable measures to mitigate the impact.
Ask what happened earlier in the aircraft or crew sequence and what Porter did to reduce the effect on your flight.
In a complaint to the Canadian Transportation Agency, Porter bears the statutory burden on the classification issue: the disruption is presumed to have been within the carrier's control and not required for safety unless Porter proves otherwise.
Do not automatically assume that the same statutory presumption governs a provincial court or tribunal proceeding. The applicable evidentiary rules depend on the forum and legal basis of the claim.
"Required for safety." Ask what specific safety issue arose, when it was discovered and what facts support the classification.
A genuine unexpected mechanical malfunction affecting passenger safety may qualify. Scheduled maintenance undertaken in compliance with legal requirements does not.
If Porter relies on an earlier safety-related disruption, ask how that event affected your later flight and what mitigation occurred.
"We already refunded you." A refund does not automatically extinguish every possible claim.
For a qualifying within-control disruption where a refund is provided under section 17(2), section 19(2) expressly provides compensation of $400.
That is different from an outside-control cancellation. If section 18 applies and you properly choose a refund after Porter cannot meet the initial 48-hour rebooking requirement, standardized section 19 compensation is generally not payable because the underlying disruption is outside Porter's control.
A refund also does not necessarily determine separate claims for expenses or damages under another legal regime.
If the claim remains unresolved, send a formal demand letter identifying the passenger, flight, amount, legal basis and supporting evidence. Give Porter a reasonable deadline, such as 14 days, and preserve proof of delivery.
After that, consider the appropriate enforcement route.
A complaint to the Canadian Transportation Agency is free for passengers. The Agency can order compensation, refunds and qualifying expense reimbursement, although its complaint process can involve a significant wait before assignment.
A provincial court or tribunal may provide another route where jurisdiction exists. In British Columbia, qualifying civil claims up to $5,000 can proceed through the Civil Resolution Tribunal, and the BC Court of Appeal has confirmed the CRT's jurisdiction to adjudicate APPR compensation disputes within its statutory jurisdiction.
The best forum depends on the amount claimed, evidence available, remedy sought and procedural rules that apply.
