What is the size of a carry-on in Canada?

The standard carry-on size in Canada is 55 x 40 x 23 cm (21.5 x 15.5 x 9 in) including wheels and handles — that's the Air Canada carry-on limit, and it's the tightest spec among major Canadian carriers. Buy a bag that fits this number and it will clear WestJet, Porter, and Flair without a second thought. Knowing the exact dimensions before you buy is the difference between boarding with your luggage and paying a surprise gate-check fee.

Canadian airline carry-on size limits compared (2025–2026)

Air Canada's 55 cm height limit is the strictest among Canadian majors — WestJet and Flair both allow 56 cm, and Porter comes in at 53 cm. That 3 cm spread sounds small, but a bag labelled "22 inches" by the manufacturer often measures 56–57 cm overall once you add spinner wheels and a top grab handle, which means it clears WestJet's sizer and fails Air Canada's. The table below lists the 3 active carriers most GTA travellers use, with direct links to each airline's official baggage page so you can verify the figures yourself.

All dimensions above include wheels and handles — that detail matters more than most buyers realize. A bag advertised as "21-inch" often measures 23–24 inches once you factor in spinner wheels and the top grab handle. Always check the manufacturer's overall dimension, not the shell measurement alone.

What is the standard carry-on size for Air Canada specifically?

Air Canada's carry-on maximum is 23 x 40 x 55 cm (9 x 15.5 x 21.5 in), wheels and handles included, with no published weight ceiling — though the bag must be light enough to lift into the overhead bin without assistance. Economy Basic fares purchased on or after January 3, 2025 restrict passengers on select itineraries to 1 personal item only, with no standard overhead carry-on permitted. If you're connecting internationally on an Economy Basic fare, Air Canada does allow 1 standard carry-on plus 1 personal item for that leg specifically — worth checking before you pack.

At our Woodbridge store we field this question almost daily from customers flying out of Toronto Pearson. Honestly, the answer is simple: a bag sized to Air Canada's 55 cm height clears every other major Canadian carrier too, since it's the tightest limit on the market. Buy to that number and you're covered coast to coast.

• 21-inch spinner: typically 54–56 cm overall — sits right at the line
• 22-inch carry-on: often 56–57 cm — may fail Air Canada's automated sizer
• 20-inch carry-on: typically 51–53 cm — comfortably under all Canadian limits
• Personal item / underseat bag: target 40 x 30 x 15 cm to clear every airline

Our carry-on luggage collection lists overall dimensions (wheels included) on every product page — not just the shell measurement — because that's the number the gate agent's sizer actually measures.

What are the new rules for carry-on luggage in 2026?

The most significant policy change for Canadian travellers in 2025–2026 is Air Canada's Economy Basic fare restriction: passengers on that fare class, on select domestic and transborder routes, are now limited to 1 personal item only — no standard overhead carry-on. That rule took effect January 3, 2025, per Air Canada's published carry-on policy. WestJet and Porter have not introduced equivalent fare-class carry-on restrictions as of mid-2026, though both carriers continue to enforce their existing size limits at the gate.

Practically speaking: if you fly Air Canada regularly and book Basic fares to save money, a compact underseat carry-on or personal item bag becomes your primary cabin bag. Slim 20-inch options and structured personal item bags are what we've been pointing those customers toward at both our Woodbridge and Vaughan Promenade locations.

Is a carry-on 22 inches or 24 inches?

The carry-on sweet spot for Canadian airlines is 21–22 inches (53–56 cm) in height including wheels — not 24 inches. A 24-inch bag is a medium checked bag; it will not fit in any Canadian carrier's overhead bin and will be gate-checked, often with a fee. The "22-inch" label you see on most bags refers to the shell height only — add spinner wheels and you're typically at 23–24 inches total, which is why some "22-inch" bags fail Air Canada's 55 cm (21.5 in) sizer.

Here's the thing: the luggage industry labels bags by shell height, but airlines measure the whole bag. That 1-inch gap catches a surprising number of travellers off guard. When a customer at our Vaughan Promenade store asks for "a 22-inch carry-on," the first thing we do is pull out the tape and measure wheels-included before we write up the sale. It takes 30 seconds and saves a gate-check fee.

Choosing the right carry-on: 8 things to check before you buy

Three factors compound the sizing decision beyond the raw centimetre spec: how often you book Basic fares, which airlines you fly most, and whether you travel with a personal item simultaneously. Getting all 3 right means you never pay a surprise gate-check fee. The list below covers what we walk every customer through before a purchase.

1. Match your primary airline's tightest limit — Air Canada's 55 cm height is the strictest among Canadian majors; buy to that spec.
2. Measure wheels-included, not shell-only — spinners add 2–3 cm; in-line wheels add less.
3. Hard-shell polycarbonate bags don't expand — the stated dimension is the real dimension; soft-side bags can compress slightly at the sizer.
4. Frequent Economy Basic flyers should consider a 40 x 30 x 15 cm underseat bag as their primary cabin bag on Air Canada domestic routes.
5. International connections change the math — some European carriers enforce stricter limits (45 x 36 x 20 cm on Ryanair, for example); if you connect internationally, size down.
6. Porter's 10 kg weight limit is the outlier — most polycarbonate 21-inch bags weigh 3–4 kg empty, leaving 6–7 kg for contents; weigh your packed bag before a Porter flight.
7. Anti-theft features don't add measurable bulk — a Pacsafe or Briggs & Riley carry-on with TSA-approved locks and RFID-blocking pockets stays within the same external dimensions as a standard bag.
8. Expandable carry-ons expand past the limit — always measure in the un-expanded state; a gate agent who notices the expansion zipper open will gate-check the bag regardless of the collapsed measurement.

We carry Briggs & Riley, Samsonite, Pacsafe, Aleon, and Verage carry-ons at both our Woodbridge and Vaughan Promenade locations — every one measured wheels-included on the shelf tag. Hard-shell polycarbonate carry-ons from brands like Aleon and Briggs & Riley hold their shape through repeated overhead bin compression better than ABS or soft-side alternatives, which means the dimension you buy is the dimension you keep after 50 flights. You can also browse our full carry-on range online with dimensions listed on each product page.

If you want to compare sizes in person before flying, stop by either of our GTA stores — we'll measure your current bag against your airline's published spec and help you find a replacement that fits without any guesswork. You can also reach us through our website if you want to sort out sizing before making the trip in.

Frequently asked questions

Will Air Canada accept 22 inch carry-on?

It depends on the total measurement including wheels. Air Canada's limit is 55 x 40 x 23 cm (21.5 x 15.5 x 9 in) wheels and handles included. A bag labelled "22 inches" typically measures 56–57 cm overall with spinner wheels, which exceeds Air Canada's 55 cm height limit. A true 21-inch bag (54 cm overall) is the safer choice for Air Canada flights.

What are the new rules for carry-on luggage in 2026?

The most significant change is Air Canada's Economy Basic fare restriction, effective January 3, 2025: passengers on that fare class on select routes are limited to 1 personal item only — no standard overhead carry-on. WestJet and Porter have not introduced equivalent restrictions as of mid-2026, but both enforce existing size limits more strictly at the gate than before.

Is a carry-on size 22 or 24?

Standard carry-on luggage for Canadian airlines runs 21–22 inches (53–56 cm) in height including wheels. A 24-inch bag is a medium checked bag and will not fit in any Canadian carrier's overhead bin. The "22-inch" label refers to shell height only; add wheels and handles and the real measurement is often 23–24 inches, which can exceed Air Canada's 55 cm limit.

What size bag can I bring on a plane in Canada?

Most Canadian carriers allow a standard carry-on up to 55–56 cm (21.5–22 in) tall including wheels, plus one personal item up to roughly 43 x 33 x 16 cm. Air Canada's 55 cm height limit is the tightest among major Canadian airlines. A bag sized to Air Canada's spec will clear WestJet, Porter, and Flair as well.

What is the maximum size for carry-on luggage in Canada?

The largest carry-on permitted by a major Canadian carrier is 56 cm in height (WestJet and Flair), but Air Canada — the country's largest airline — caps it at 55 cm including wheels and handles. To be safe across all Canadian carriers, keep your carry-on at or under 55 x 40 x 23 cm total.
