Exact dimensions of Air Canada carry-on baggage (23 x 40 x 55 cm)
Air Canada carry-on baggage is strictly limited to 23 cm deep, 40 cm wide, and 55 cm high, including wheels and handles. This rule applies to all flights operated by the company as well as Air Canada Express and Air Canada Rouge partner flights. The sizing gauge at boarding gates is calibrated to these exact dimensions: any excess, even 2 cm, will result in a fee for checked baggage. To anticipate, measure your carry-on luggage with a tape measure, including all protruding elements. Our carry-on baggage size guide details the differences between European and North American airlines.
What are the maximum dimensions for carry-on baggage with Air Canada?
The maximum dimensions for carry-on baggage with Air Canada are 23 x 40 x 55 cm, or 9 x 15.5 x 21.5 inches. This size, identical for Economy, Premium Economy, Business, and Signature Class, places Air Canada within the global average, slightly more generous than European low-cost airlines like Wizz Air or Ryanair. For a cross-company comparison, see our Air France carry-on baggage guide.
Personal item allowed in addition to carry-on suitcase
In addition to the carry-on suitcase, each passenger may bring one personal item measuring a maximum of 16 x 33 x 43 cm: a handbag, backpack, laptop bag, device bag, briefcase, or small item. This bag must fit under the seat in front of you. Air Canada also accepts, free of charge and not counting towards the quota, a coat, an umbrella, prescription medications, CPAP respiratory devices, as well as a diaper bag or a car seat per child.
How to store baggage on board in the cabin
Carry-on luggage must be stored in the overhead compartment, with wheels facing the interior of the aircraft to facilitate boarding. The personal item, on the other hand, slides under the seat in front of the passenger. On Air Canada Express flights operated by Jazz Aviation, some regional aircraft have reduced overhead compartments: an agent may then request that the carry-on suitcase be checked at the boarding gate, free of charge via the SkyCheck service.

Air Canada carry-on baggage weight limit: the "lift it yourself" rule
Air Canada does not impose any strict weight limit on carry-on baggage, unlike most European airlines which cap it between 8 and 12 kg. The company applies a pragmatic rule: each passenger must be able to lift their carry-on bag themselves into the overhead compartment, without assistance from the cabin crew. This policy, inherited from North American airlines, aims to streamline boarding and prevent staff injuries.
Is there a weight limit for carry-on bags with Air Canada?
No, Air Canada does not set a specific weight limit for carry-on baggage, but the passenger must be able to lift their carry-on suitcase into the overhead compartment unaided. In practice, aiming for a carry-on bag between 8 and 10 kg remains prudent to ensure autonomy and avoid a request for transfer to checked baggage by an agent at the counter.
Why prioritize a lightweight carry-on suitcase for Air Canada
A rigid ABS suitcase weighing less than 2.5 kg empty leaves a comfortable usable margin for clothes, a laptop, and personal effects. Polycarbonate Maxlite models even go below 2 kg. For an international Air Canada flight from Montreal to Toronto to Paris, planning for a lightweight carry-on bag avoids getting stuck at inspection or boarding. Our selection of KLM compatible carry-on suitcases also covers Air Canada's size requirements.
Practical tips for staying within limits
- Choose a rigid or soft-sided suitcase under 2.5 kg empty
- Pack shoes and heavy items at the bottom, near the wheels
- Slip laptop, tablets, and charger into the backpack accompanying the suitcase
- Check the weight on a home scale before departure
- Keep a 1 kg margin for duty-free purchases
Air Canada Basic Economy Fare: New Carry-on Baggage Rule 2025
As of January 3, 2025, carry-on baggage is no longer included in the Basic Economy fare on flights within Canada, to the United States, Mexico, Central America, and the Caribbean. Only the personal item remains authorized free of charge. This update, aligned with Air Canada Cargo and US carrier practices, may surprise customers booking through a comparison site without reading the fare conditions. For official details, consult Air Canada's carry-on baggage page. If you combine an Air Canada flight to the Antilles with a French carrier, also compare the Air Caraïbes carry-on baggage rules, which serves the same destinations from Paris Orly.
Is carry-on baggage always included in the Air Canada ticket price?
No, as of January 2025, carry-on baggage is no longer included in Air Canada's Basic Economy fare on North American domestic flights and to the Caribbean. Comfort, Flex, Latitude, Premium Economy, Business Class, and Signature Class fares continue to include one carry-on suitcase plus one personal item at no additional charge.
Carry-on baggage fee if added to Basic Economy fare
Adding a carry-on suitcase to a Basic Economy fare costs between 35 and 50 CAD (approximately 24 to 34 euros) if done online during booking, and up to 65 CAD at the boarding gate. Booking the Comfort fare is often cheaper than combining Basic and carry-on baggage, while also unlocking seat selection. Aeroplan Elite, Aeroplan Prestige, and Star Alliance Gold holders retain their free carry-on allowance regardless of the fare purchased.
How to check for carry-on baggage inclusion in your reservation
On the Air Canada website or mobile app, open the "My Trips" tab, select the reservation, then consult the "Baggage" section. The details precisely list the carry-on allowance, checked baggage, and any potential fees per segment. If in doubt before check-in, Air Canada's baggage calculator displays the rules according to the fare, Aeroplan status, and destination.
Air Canada personal items: carry-on suitcase plus backpack allowed
Yes, Air Canada allows one carry-on suitcase plus one backpack on board for each passenger, provided the fare includes it. The backpack counts as a personal item and must adhere to the 16 x 33 x 43 cm format. It must be stored under the seat in front to free up the overhead compartment. This dual allowance, more generous than many European low-cost carriers, simplifies travel with a laptop, camera, or professional camcorders.
Can I bring a carry-on suitcase and a backpack on board?
Yes, Air Canada passengers can bring one carry-on suitcase measuring 23 x 40 x 55 cm plus a backpack or handbag measuring 16 x 33 x 43 cm. The backpack counts as a personal item and fits under the seat. This rule applies to all Air Canada fares except Basic Economy, which only allows a personal item.
Additional free items on board
In addition to the carry-on suitcase and backpack, Air Canada accepts several items free of charge and without counting towards the allowance: a coat, umbrella, baby carrier bag, diaper bag, child car seat, foldable stroller, prescription medication with label, CPAP respiratory device, and a small musical instrument that can be stored in the overhead compartment. Passengers traveling with a pet in the cabin benefit from a soft-sided pet carrier counting as a personal item.
Special cases for Air Canada Express and Air Canada Rouge
On regional Air Canada Express flights operated by Jazz Aviation, as well as on some high-density configured Air Canada Rouge aircraft, the overhead compartment may be insufficient for all carry-on suitcases. The free SkyCheck service then allows you to drop off your suitcase at the boarding gate with a baggage tag: it is retrieved at the arrival counter, free of charge. For connections, anticipate that this service slightly slows down airport exit.
Liquids and prohibited items in Air Canada cabin baggage
Air Canada carry-on baggage applies the 100 ml rule defined by the Canadian Air Transport Security Authority and the Canada Border Services Agency. All liquids, gels, aerosols, creams, and beverages must be in individual containers of 100 ml maximum, grouped together in a transparent, resealable plastic bag of 1 liter maximum. This bag is presented separately at security screening.
What are the rules regarding liquids in cabin baggage?
Liquids in Air Canada cabin baggage are limited to containers of 100 ml maximum, grouped in a transparent plastic bag of 1 liter per passenger. This rule includes toiletries, gels, perfumes, beverages, liquid cosmetics, and certain foods like yogurts or sauces. Prescription medications, infant formula, and baby food benefit from exemptions upon presentation at security.
Items prohibited in cabin on Air Canada flights
Several categories of items are strictly prohibited in carry-on baggage: gas lighters like Bic Zippo (a simple gas lighter is tolerated on the person), non-safety matches, external lithium batteries like Anker Zolo A1689 beyond 100 Wh, electronic cigarettes and vapes in the carry-on suitcase (only allowed on the person), knives and blades longer than 6 cm, hair gels over 100 ml, bottles of beverages purchased outside duty-free areas, wet ice for refrigeration.
Medications, baby food, and exceptions
Liquid prescription medications, infant formula, baby food, and medical solutions necessary during the flight are allowed in reasonable quantities beyond 100 ml. Present these products separately for inspection, ideally accompanied by the medical prescription in French or English. Containers must be clearly labeled. Canadian Air Transport Security Authority agents may request to taste or test certain products.
Air Canada carry-on baggage fees for non-compliant or oversized items
Carry-on baggage that does not comply with the dimensions of 23 x 40 x 55 cm or is added to a Basic Economy fare incurs immediate fees at the airport. At the boarding gate, the fee can go up to 100 CAD (approximately 68 euros) for a forced transfer to checked baggage, compared to 35 to 50 CAD if the addition is made online before check-in. Transport Canada security rules require carriers to strictly apply these limits for cabin safety.
What are the fees if my carry-on baggage exceeds the allowed limits?
An oversized Air Canada carry-on bag is transferred to checked baggage for a fee ranging from 35 to 100 CAD depending on the route, fare, and time of payment. Flights within Canada are the least expensive, international flights the most costly. Booking and paying online before check-in remains systematically more advantageous than payment at the boarding gate.
Anticipate oversized baggage fees before departure
Measuring your carry-on suitcase at home with wheels and handles 48 hours before the flight avoids unpleasant surprises at the check-in counter. Self-service kiosks at Montreal-Trudeau and Toronto Pearson are equipped with physical sizing gauges calibrated to 23 x 40 x 55 cm. In case of doubt, paying for checked baggage online before arriving at the airport is more economical than the inspection procedure at the boarding gate.
SkyCheck service for Air Canada Express and Rouge flights
On regional flights where the overhead compartment is full, the SkyCheck service transfers carry-on baggage to checked baggage free of charge from the boarding gate, with retrieval at the arrival counter. This service clearly distinguishes Air Canada from carriers that systematically charge for forced transfers. Keep your medications, laptop, documents, and boarding pass in your backpack before handing over the suitcase to the agent.
