How to Fly With a Cat From Canada: Cabin Rules and Security

A cat is one of the easiest animals to fly with and one of the most stressful to fly with, and both of those are true at once. The logistics are simple, because almost every cat is small enough for the cabin and the fee is flat. The difficulty is everything around the flight, and most of it happens in about ninety seconds at a security checkpoint.

This guide covers travelling with your cat in the cabin on a Canadian departure, with you on the same aircraft. If you want the cost side, our Canadian pet shipping cost guide carries the numbers. If the cat is moving within Canada without you, our guide to moving a cat across the country covers that. Airline and screening figures verified from the carriers and from CATSA, checked September 2026.

Most airlines flying out of Canada will take a cat in the cabin, and the cabin is where you want it. The animal never leaves your sight, never changes aircraft without you, and never waits on a ramp in a Canadian winter. For a cat this is almost always achievable, which is the opposite of the situation facing an owner with a large dog.

The question is therefore not which service to buy but whether the carrier fits under the seat in front of you, and on Air Canada that question has a newer answer than most guides give.

Since 1 June 2025, Air Canada requires cabin pets to travel in soft-sided carriers on Air Canada, Rouge and Express flights. Backpack carriers with hard plastic windows are barred. The practical consequence is blunt: a hard kennel that boarded a year ago does not board now, and a carrier bought before that change may no longer be usable.

The second surprise is which aircraft is most generous. On Air Canada the regional types, the Dash 8-400, the Embraer 175 and the CRJ900, allow a larger carrier than the mainline fleet, which is the reverse of what a smaller aircraft on the booking suggests. Check the carrier limit for the aircraft on your specific leg rather than the airline’s general figure.

Our Air Canada pet policy guide carries the current fees, the full carrier dimensions by aircraft, the winter weight restriction that runs from 1 November to 31 March, the checked baggage blackout from 18 December to 4 January, and the codeshare exclusion. Our Canadian airline pet policies guide compares the carriers.

Buying your own ticket does not book your cat. Every airline caps how many animals travel in each cabin on a given flight, usually at a low number, and those places are inventory rather than a service you buy on the day. Once they are taken on your flight, they are taken.

So choose the flight, add the cat in the same session, and treat the booking as unfinished until the airline has confirmed the animal. If you are travelling with someone else, book both tickets first, because a second cat generally needs a second passenger as well as a second fee.

Your cat does not go through the X-ray machine, and neither does its carrier with the cat inside. CATSA asks you to remove the animal from its carrying case so that the empty carrier can be screened separately, and to keep the animal close and under control while that happens.

The detail worth knowing, and the one that differs from the United States, is what stays on the animal. CATSA asks you to take off items attached to the pet such as jackets or accessories, but collars and harnesses can stay on. American screening under the TSA runs the other way and asks for the leash to come off before you carry the animal through the metal detector. So a cat flying from Toronto keeps its harness on through the checkpoint, and the same cat flying home from a US airport does not.

That single difference is worth planning around, because a harness is the only thing standing between a startled cat and an open concourse. Put the harness on before you leave home either way, and on the American leg expect to be holding the cat directly.

Screening officers may offer a private search room. The steps are the same in there, but the space is quieter and enclosed, which matters for a cat that is easily startled. Ask rather than wait to be offered.

One more rule that surprises people at the belt: your cat does not get extra liquids allowance. Solid pet food travels in carry-on without restriction, but wet food and anything spreadable follows the standard rule of containers of 100 ml or less inside a single one litre resealable bag, and that is the same bag as your own liquids. Anything larger goes in checked baggage.

Feed a light meal several hours before departure rather than nothing at all or a full bowl on the way out of the door. A cat that has not eaten since the previous evening is a cat with low blood sugar in a stressful place, and a cat that has just eaten may be sick in a closed carrier.

A clip-on water bowl will empty itself during taxi. Offer water at the gate and again after landing, and carry a small collapsible bowl rather than trying to keep water available in the air.

An absorbent pad in the base of the carrier handles a flight of a few hours. Bring two spares and a sealable bag. On a long-haul departure ask the airline whether the carrier may be taken into a lavatory, because policies differ and the answer is occasionally yes.

It is a fair question, and the honest answer has two halves.

The flight itself is not the hard part. A cat in a carrier under a seat is in a dark, enclosed, familiar-smelling space, which is close to what a stressed cat would choose for itself. Cabin pressure and temperature are the ones you experience. Most cats settle within twenty minutes of the doors closing and sleep.

The hard parts are the car, the terminal and the checkpoint, in that order, and all three happen before boarding. So the preparation that matters is not about the air time. It is carrier training in the weeks beforehand, a harness that fits properly, and enough margin in the schedule that nobody is rushing.

There are cats for which the answer is genuinely no. A very old cat, a cat with a heart or respiratory condition, or a cat that cannot be handled without sedation is a conversation with a veterinarian before anything is booked. Carriers set their own conditions on a medicated animal and the two Canadian ones do not set the same conditions, which our guide to sedating a pet for a flight from Canada covers.

Three things push a cat out of the cabin. A household moving more than two cats, since airlines cap a traveller at two animals and require a second passenger for the second one. A route or ticket that does not permit animals in the cabin, which includes codeshare itineraries on Air Canada. And a destination whose import rules require the animal to arrive as manifest cargo rather than as accompanied baggage, which is a government rule rather than an airline one.

In each case the animal moves as cargo and the pricing changes from a flat fee to a quoted freight rate. Winter adds a fourth: Air Canada restricts cabin travel by weight between 1 November and 31 March, which can move a borderline cat into the hold in exactly the months you would least want it there.

The airline will carry a cat it is satisfied with to a country that will not accept it, so the document work is a separate job from the booking. On a Canadian departure the export side runs through the Canadian Food Inspection Agency rather than through the airline, and the destination sets the requirements, not Canada. Our CFIA health certificate guide covers that side.

Start the document work from the destination’s deadlines and count backwards to the flight, rather than booking the flight and fitting the paperwork around it. On several routes the rabies antibody titre alone sets the earliest possible travel date months ahead.

For an accompanied cabin move the work is sequencing and checking. We confirm the aircraft on each leg rather than the airline, because on Air Canada the carrier limit moves with the aircraft type and the regional fleet is the generous one. We check how the ticket is issued, since a codeshare itinerary can bar the animal outright. And we hold the destination’s document deadlines against the flight date rather than the reverse.

Where the cabin is not available we quote the cargo route plainly rather than treating it as a failure, and we say early when a particular cat should not be flying at all.

We are licensed and insured, and our team holds IATA Live Animals Regulations certification. Export documentation from Canada follows CFIA requirements.

Yes, in the cabin, in a carrier that fits under the seat in front of you. On Air Canada, Rouge and Express the carrier must be soft-sided, a rule that took effect on 1 June 2025. The cat stays in the carrier for the whole flight.

Yes. CATSA asks you to remove the animal so the empty carrier can be screened separately. Collars and harnesses may stay on, which differs from American screening, where the leash comes off before you carry the animal through the metal detector. Ask for a private search room if your cat is easily startled.

Usually only with two passengers. Airlines allow one animal per carrier and generally cap each traveller at one cabin animal, so a second cat needs a second person on the booking as well as a second fee. Check your carrier before assuming two cats travel together.

No. Since 1 June 2025 cabin pets on Air Canada, Rouge and Express must be in soft-sided carriers, and backpack carriers with hard plastic windows are not accepted. A hard kennel that was fine on an earlier trip is not fine now.

Not without settling it with a veterinarian first, and the carrier decides separately. Air Canada says tranquillizers and other medications are not recommended and sends you to your vet; WestJet Cargo says the same and adds that where it is necessary a notice from the administering veterinarian and a sedation record are required at tender. The CVMA advises against heavy sedation because complications in flight can be impossible to address. Carrier training in the weeks before travel is the safer path, and our sedation guide sets out the rest.

The flight is usually the calmest part, because a carrier under a seat is dark and enclosed and most cats sleep once the doors close. The stressful parts are the car, the terminal and the checkpoint. A very old cat, or one with a heart or respiratory condition, is a separate question for a veterinarian.

Screening steps come from the Canadian Air Transport Security Authority’s own guidance on flying with animals and pets, and the American comparison from the Transportation Security Administration. Air Canada carrier rules, the soft-sided requirement and the seasonal restrictions come from Air Canada’s published pages and are carried in full in our Air Canada guide. Checked September 2026. Airline pet policy changes often, so confirm the carrier limit and the fee with your airline before booking.
