Traveling With Dogs on a Plane: Canadian Airline Rules

A flight with a dog begins long before you arrive at the airport. Airlines limit the number of animals on each departure, require particular carrier dimensions and may not accept pets on every aircraft or connecting flight. A ticket for a person is not a confirmed booking for the dog.

This guide compares the practical policies of Air Canada, WestJet and Porter based on official carrier pages available in October 2026. It covers ordinary companion dogs; trained service dogs have a separate process. Policies can change, and your specific route and operating airline determine what is accepted.

Canadian airline pet policies at a glance

This comparison summarizes the airlines' public policies, not a guarantee that a particular flight has space. Confirm the actual operator, cabin, route, aircraft and pet booking before buying a ticket.

Choose the operating airline and confirm the dog's place

Your reservation may show one airline name while another company operates an individual segment. Check the carrier operating every flight and ask whether the animal can be accepted throughout the itinerary. A connection can become impossible if one airline has no pet space or does not accept interline animals.

Make the pet reservation as early as possible and request written confirmation that includes travel dates, cabin or baggage arrangement and any payment still due. Do not purchase a nonrefundable hotel or connecting ticket based only on a website's general statement that pets are allowed.

• Confirm the actual flight operator on each segment.
• Reserve the pet's space, not only your own ticket.
• Confirm pet restrictions for the cabin, aircraft and destination.
• Save the carrier's pet confirmation with your booking number.

Air Canada: soft sided carriers in the cabin

Air Canada's published pet policy says that from June 1, 2025 pets travelling in the cabin must use soft sided carriers. A small dog must fit under the seat in front and be able to stand, turn and lie down comfortably inside the carrier. A pet carrier counts toward carry on allowance, and eligibility differs by seating class and aircraft.

Dogs too large for an eligible cabin carrier may require an accepted baggage compartment arrangement or cargo service, subject to availability, destination and seasonal restrictions. Some breed and kennel restrictions apply. Always read the current Air Canada pet policy rather than treating baggage acceptance as guaranteed.

WestJet: advance booking and aircraft restrictions

WestJet accepts eligible dogs in the cabin, as checked animals or through cargo on some services, subject to route, breed, aircraft, temperature and seasonal limits. It states that pet numbers per flight are restricted and recommends requesting space promptly, generally at least 48 hours in advance.

The published in cabin kennel is soft sided, ventilated, secure and sized for under seat stowage. WestJet lists specific maximum cabin carrier dimensions and restrictions for checked kennel transport; measure your dog's actual carrier and confirm the permitted size for your flight rather than trusting a seller's 'airline approved' label.

Porter: small dogs travelling in the cabin

Porter's policy is distinct: it accepts small dogs and cats in the cabin on eligible Porter operated flights, but says it does not carry pets in the baggage compartment. The carrier must be soft sided and fit under the seat. Porter requires advance pet arrangements and limits the number of animals on each flight.

If your dog cannot fit comfortably in the permitted carrier, Porter is not an interchangeable alternative to an airline with checked pet service. It is also important to confirm how flights operated by another airline will handle your animal, since Porter's pet policy does not automatically extend to partner flights.

Cabin, checked baggage and cargo are different services

A dog travelling in the cabin remains in its carrier with the passenger. Checked animal travel places an eligible dog in an approved kennel in the aircraft hold under the airline's service and handling rules. Cargo is a separate booking and handling process, sometimes required for particular animal sizes, routes or purposes.

These options cannot be assumed interchangeable. The airline will determine eligibility, kennel requirements and any weather embargo. If the route requires the dog to travel outside the cabin, discuss fitness for that form of travel with your veterinarian and consider whether a different itinerary would be more appropriate.

How to measure and prepare a dog carrier

Measure your dog's standing height and length, then check the carrier's internal dimensions and the precise limits for the ticketed aircraft. The dog should be able to lie naturally, turn around and change posture without being compressed. A rigid crate accepted in a baggage compartment is not the same as a soft carrier intended for the cabin.

Introduce the carrier well before travel through calm, positive sessions. Practise entering and settling without forcing the dog to remain confined for long periods abruptly. Never sedate a dog for flight without individual veterinary advice, and do not assume sedation is permitted by the operating airline.

• Check under seat dimensions and seating restrictions.
• Confirm the dog can stand, turn and lie down in the carrier.
• Verify secure closures, ventilation and absorbent material.
• Check whether wheels, rigid sides or certain backpack designs are prohibited.

Documents, screening and international connections

CATSA's 2026 security advice specifies that the dog is removed from the carrier and kept under control while the empty carrier is screened separately. Officers can offer a private search room, which may be preferable for an anxious dog. Plan to keep a secure grip or suitable leash arrangement through this process; never put an animal in a baggage X ray machine. See the Canadian Air Transport Security Authority's pet screening guide for current procedures.

For a domestic flight, airline identification and animal documentation rules still apply; for international flights, government import requirements are additional. If you are flying to the United States, CDC rules may apply regardless of the airline's acceptance of the dog. Your destination and transit countries can have separate health certificate or import steps.

The Government of Canada's travel advice explains that during airport screening the carrier is screened separately; your dog is not placed through an X ray machine. Plan a secure handling method during screening, follow staff directions and use designated animal relief areas where available.

Travel day and contingency planning

Allow extra check in time and review feeding and water guidance from your operating airline, which may vary depending on cabin or baggage travel. Keep leash, identification, supplies, required documents and an emergency contact accessible.

Flight cancellation or a late connection can be particularly difficult when an animal is travelling. Decide in advance where you could stay overnight, how you would secure appropriate dog care and who to call if the pet service is no longer available on a replacement flight.

Should your dog fly at all?

For some dogs, driving or arranging trusted care is the more sensible option. Age, mobility challenges, respiratory concerns, illness, fear of confinement and previous travel distress all warrant an individual assessment before booking.

A good trip should accommodate the dog rather than force the dog to fit a convenient flight. Discuss any medical vulnerability with your veterinary team and verify that a carrier or route can realistically meet your dog's needs.

Frequently asked questions

Can my dog sit on my lap on a Canadian airline?

Ordinary pets travelling in the cabin generally must remain in an accepted closed carrier under the seat according to the operating airline's rules. Trained service dogs have separate provisions.

Does Porter fly dogs in the cargo hold?

Porter's published policy states that ordinary pets are accepted in the cabin only, not in the checked baggage compartment.

Does an airline approved carrier guarantee acceptance?

No. The carrier must meet the actual operating airline and aircraft rules, and the individual pet must have a confirmed reservation.

What if I change planes or airlines?

Confirm pet acceptance on every segment and ask about transfer responsibilities. Some interline or code share itineraries cannot accommodate pet travel.

Should I medicate my dog to keep them calm on a flight?

Do not administer sedatives or other medications for flight without discussing them with your veterinarian and checking the airline's rules.
