At CATSA, we know that one of the biggest frustrations for travellers is having to surrender items at security. To help you avoid that, here’s a look at what should stay out of your carry-on.
Weapons and replicas
Firearms, ammunition, pepper spray, brass knuckles, and even realistic toy guns are not permitted in carry-on baggage. In many cases, these items are not permitted in checked baggage either.
Sharp objects
When packing sharp objects in your carry‑on, only certain items are permitted. Disposable razors, tweezers, nail clippers, and scissors and knives with blades 6 cm or less are allowed when travelling within Canada or to international destinations outside the U.S. For flights to the United States, knives of any type or length are not permitted in carry‑on. Prohibited knives, such as switchblades, butterfly knives, or concealed knives disguised as everyday objects, are illegal and not permitted in either your carry-on or checked baggage.
Sporting equipment
Baseball bats, hockey sticks, golf clubs, and other striking sports gear cannot travel in your carry-on.
Liquids, aerosols and gels
Liquids, aerosols, and gels over 100 mL, whether shampoo, sunscreen, or even peanut butter, cannot go through security in your carry‑on. All permitted liquids must fit into one clear, resealable 1 L bag. Certain items are exempt, including medically necessary liquids and essentials for children under two years of age.
Flammable or hazardous materials
Items like fireworks, lighter fluid, and corrosive chemicals are strictly prohibited.
Final tip
If you’re unsure whether an item is allowed, use CATSA’s What Can I Bring? tool before you travel. Remember, screening officers make the final call at the checkpoint.
A little preparation before you pack can save you time and stress at the checkpoint.
