A departures board that reads "delayed" is almost useless as information. It tells you nothing about whether you will be fed, rebooked, housed overnight or paid, because in Canada none of those turn on the length of the wait alone.

They turn on a single question: was the cause within the airline's control? Everything in the regulations flows from the answer, which is why the reason given at the gate is worth more attention than the new departure time.

The first thing to do.

Get the reason, and get it recorded. Ask at the gate, check the app, and take a screenshot of whatever the airline puts in writing. Airlines are required to tell you why the flight was disrupted as soon as is feasible, so this is not an unreasonable request.

Why it matters so much: "crew scheduling" and "weather" sit in different categories and produce entirely different entitlements. If the stated reason later changes, having the original in writing is what makes a claim straightforward rather than contested.

Then, in order: check whether you have a connection at risk, join the rebooking queue early rather than waiting to see what happens, and tell whoever is meeting you before they set off.

How you’ll be told.

The communication rules are more prescriptive than most travellers realise. Airlines must inform you of the disruption through an audible announcement, a visible announcement on request, and the communication method you selected, such as email or SMS.

They must then provide status updates every 30 minutes until a new departure time is confirmed, and offer new information sooner if it becomes available. They must also tell you which standards of treatment and compensation apply, and about your recourse options including complaining to the regulator. Communication must be accessible, with digital formats compatible with adaptive technologies and paper alternatives available in large print, Braille or digital form on request.

Toronto Pearson runs its own channels alongside the airline's. You can set up SMS notifications from a flight's page on the airport site, and a gate tracker at flights.torontopearson.com is reachable directly or by scanning a QR code shown on check-in and gate screens. The airport's departures listing covers yesterday, today and tomorrow. You can also check the live status of your flight before leaving home.

The question that decides everything.

Canada's regulations sort every disruption into one of three categories, and your entitlements follow from which one applies. This is the part most guides skip, and it is the part that matters at the gate.

In all three cases the airline must still ensure you complete your itinerary and reach your final destination. That obligation never disappears.

What you’re owed during the wait.

Standards of treatment apply to departure delays within the airline's control, including those required for safety. They do not apply to delays outside its control, which is the single most common misunderstanding on this subject.

After a two-hour departure delay, the airline must provide:

• Food and drink in reasonable quantities
• A means of communication, such as free wifi

If you must wait overnight, it must offer hotel or comparable accommodation free of charge, together with free transport to and from it.

In practice the offer is often a voucher and a shuttle, and the hotel may be some distance from the airport. If you would rather stay somewhere specific, ask what the airline will reimburse before booking it yourself, and keep receipts. Getting into the city instead is a reasonable choice for a long overnight wait, and hotel transfers across the downtown core are straightforward to arrange.

Compensation.

Compensation is owed for delays and cancellations within the airline's control and not required for safety. Two details are frequently got wrong: the amount depends on how late you arrive at your final destination, not on how long the departure was delayed, and the figures differ by carrier size.

Compensation must be offered in monetary form. An airline may also offer an alternative such as a voucher, but you always choose which you take, and any alternative must be worth more than the cash amount and must never expire. If you are offered a travel credit, you are entitled to decline it and take the money.

Rebooking and refunds.

Once a delay reaches three hours, or a flight is cancelled, the airline must offer alternative travel arrangements in the same class of service using a reasonable route. It must rebook you on its own next available flight or one operated by a commercial partner.

The thresholds that force a large carrier onto a competitor differ by category:

• Within the airline's control, whether or not safety-related: if its own or a partner's next flight would not leave within nine hours of the original departure time, a large carrier must book you on any airline, including a competitor.
• Outside the airline's control: the same obligation applies if no flight departs within 48 hours of the end of the event that caused the disruption.
• Another airport: if a large airline cannot rebook you from the same airport within 48 hours, it must book you from another nearby airport if one is available.

For disruptions other than those outside the airline's control, you may take a refund instead of a rebooking if the arrangements offered do not meet your travel needs, or if the trip no longer has a purpose. Taking the refund does not forfeit compensation: where the disruption was within the airline's control and not required for safety, large airlines must still pay $400 and small airlines $125.

One practical note if you are rebooked at Pearson: a different flight can mean a different building, so confirm which terminal your rebooked flight uses rather than assuming it leaves from where you are standing.

Tarmac delays.

If you are held on the aircraft, separate rules apply, and they are strict.

During any tarmac delay, in Canada or abroad, the airline must provide working lavatories, proper ventilation and heating or cooling, food and drink, and the ability to communicate with people outside the aircraft free of charge where feasible.

After three hours on the tarmac at a Canadian airport, the airline must return to the gate so passengers can disembark. One narrow extension exists: the aircraft may remain up to 45 further minutes if take-off is likely within that window and the required standards of treatment continue. Beyond that, the aircraft must return to the gate, unless prevented for reasons of safety, security, customs or air traffic control.

Connections.

The regulations apply to connecting flights, and the airline's duty to ensure you complete your itinerary runs to your final destination rather than to the next airport.

That has a useful consequence. Because compensation is measured by arrival delay at the final destination, a 90-minute delay leaving Pearson that causes you to miss a connection and arrive ten hours late can carry the full entitlement, even though the original delay was well under three hours.

If you are connecting through Pearson rather than starting here, ask at the transfer desk rather than the gate, and check whether your checked bags have been re-tagged. If they have gone astray as well, our guide on what to do if your bag doesn't arrive either covers that side of it.

Denied boarding pays differently.

Worth knowing because delays and overbooking often coincide. Denied boarding happens when you hold a valid ticket but no seat is available. The amounts are substantially higher than delay compensation and the bands start earlier.

Before denying boarding for reasons within its control, an airline must seek volunteers, and must put the agreed benefits in writing before the flight departs. Compensation is payable when you are notified, or within 48 hours if payment cannot be made before your new departure time, and can be topped up if your actual delay proves longer than expected. Rebooking and treatment obligations then apply as for any delay.

How to claim afterwards.

Very few people claim, largely because the window is longer than they assume and the moment passes.

1. You have one year from the disruption to claim with the airline that operated the flight.
2. Claim in writing, with flight number, date, route, the stated reason and your actual arrival time at the final destination.
3. The airline has 30 days to respond, either by paying or by explaining why it believes compensation is not owed.
4. Escalate if needed. Airlines must tell you about your recourse options, and unresolved disputes can go to the Canadian Transportation Agency's air passenger protection service.

You do not need to pay anyone a percentage to file on your behalf. The claim is a form and a paragraph, and the regulations put the burden on the airline to explain a refusal.

The reform that hasn’t landed yet.

You will find articles describing a different, simpler Canadian regime in the present tense. Treat them carefully.

Parliament amended the Canada Transportation Act in June 2023 to eliminate the three categories and require airlines to compensate passengers for any disruption unless they can prove clearly defined exceptional circumstances. But the Canadian Transportation Agency must still amend the regulations to give effect to that, and its published guidance continues to set out the three-category regime described above.

If you’re the one waiting at arrivals.

Half the people reading this are not on the aircraft. If you are collecting someone, the useful guidance is different.

• Track the aircraft, not the schedule. A published arrival time updates slowly; the inbound aircraft's actual position does not.
• Add the exit time, not just the landing time. Deplaning, walking, border processing and baggage all sit between wheels-down and the arrivals door, and international arrivals can take considerably longer than domestic.
• Do not wait on the terminal roadways. Pearson's free cell phone waiting area exists precisely for this, and the Express Pass gives a short free window in the garages. Curbside waiting is not permitted.
• Agree a meeting point in advance, because a rebooked flight can arrive at a different terminal from the one you planned for. Our guide to where each vehicle type meets you covers both.
• Ask them to text once through customs, not once they land. Those are different moments and often an hour apart.

If you are dropping someone off rather than collecting, the timing question runs the other way, and how early to arrive at Pearson sets out the buffers by flight type.

Six mistakes that cost people money.

• Not getting the reason in writing. The stated cause is the whole basis of a claim.
• Accepting a voucher without asking. Compensation must be offered in cash, and the choice is yours.
• Measuring the delay at departure. The clock that matters is arrival at your final destination.
• Waiting to see what happens. Rebooking options thin out while the queue grows.
• Assuming treatment applies to every delay. Food, drink and hotels are owed for delays within the airline's control, not outside it.
• Never claiming. You have a full year, and the airline must answer within 30 days.

Pickups that follow the aircraft.

A delay creates one logistical problem that no regulation addresses: the car booked against a schedule that no longer exists.

This is where a pre-arranged transfer behaves differently from a walk-up option. When your flight number is on the reservation, the arrival is monitored and dispatch works from the actual landing rather than the printed time. Obsidian Ride operates 24/7 dispatch with real-time flight tracking and includes complimentary wait time on airport pickups.

Two things still help on your side. Put the flight number on the booking rather than only a time, and send a message if you are rebooked onto a different flight, since a new flight number is new information that no tracking system can infer. Full details are on the Pearson Airport chauffeur service page.
