Carry-On Only: The Complete Guide for Canadian Travellers in 2026
Why Carry-On Only Makes Sense in 2026
Checked bag fees from Canadian airports have climbed significantly. A round-trip with one checked bag can add $60 to $120 CAD to your ticket price depending on the airline. For a couple travelling together, that's potentially $240 CAD — enough for a nice dinner in Paris or two nights at a budget hotel.
Beyond the savings, flying carry-on only eliminates one of travel's most frustrating experiences: waiting at baggage claim for 30+ minutes after a long flight. You walk off the plane and straight to the taxi or transit.
Carry-On Size Rules for Canadian Airlines
| Airline | Max Carry-On Size | Max Weight |
|---|---|---|
| Air Canada | 55 x 40 x 23 cm | 10 kg |
| WestJet | 51 x 43 x 25 cm | 10 kg |
| Porter Airlines | 53 x 38 x 23 cm | 10 kg |
| Flair Airlines | 41 x 15 x 33 cm | 7 kg |
| Lynx Air | 40 x 20 x 55 cm | 10 kg |
| Air Transat | 51 x 38 x 23 cm | 10 kg |
Flair Airlines has much stricter carry-on limits than other Canadian carriers. If flying Flair, you'll likely need to check even a standard carry-on bag — factor this cost into your total fare comparison.
The Carry-On Packing System That Actually Works
Step 1: Choose the Right Bag
A well-designed 40L backpack or carry-on that meets Air Canada and WestJet dimensions will work for most trips up to two weeks. Look for bags with compression straps, laptop compartments, and easy-access pockets. Brands like Osprey, Away, and Aer make excellent travel-specific carry-ons.
Step 2: Use Packing Cubes
Packing cubes are the single best investment for carry-on travel. They compress your clothes, keep everything organized, and make it easy to find items without unpacking your entire bag. Use one cube per category — tops, bottoms, underwear/socks.
Step 3: The 5-4-3-2-1 Packing Rule
For a one-week trip: 5 pairs of underwear and socks, 4 tops (mix of casual and one nicer shirt), 3 bottoms (pants/shorts that can be mixed and matched), 2 pairs of shoes (wear the bulkier pair on the plane), 1 jacket or outer layer.
Liquids Rules for Canadian Airports
- All liquids must be in containers of 100ml or less
- All containers must fit in one clear resealable bag (1L max)
- One bag per person — remove from your carry-on at security
- Solid toiletries (shampoo bars, solid deodorant) don't count as liquids
- Buy toiletries at your destination or use hotel products to save space
