Security Enhancements

Carry-on and checked baggage

As security enhancements have a direct impact on baggage policies and the determination of restricted or prohibited items, travellers are asked to consult our checked or carry-on baggage policies.

The Canadian Air Transport Security Authority (CATSA) website also provides essential information, as well as practical how-to videos that explain many aspects of the pre-board screening process.

Liquids and gels

Only liquids, gels and aerosols in containers of 100 ml/100 g (3.4 oz.) or less are permitted in carry-on baggage. Containers over 100mL/100g (3.4oz) will be confiscated at the security checkpoint.

If your itinerary includes a connecting flight, do not purchase liquids or gels in containers over 100mL/100g (3.4oz) within the secure area at the airport or on board the aircraft unless you are sure to have:

  • access to your checked baggage between connecting flights, and
  • room in your checked baggage to pack your duty-free purchases before rechecking your bags for your next flight.

Our Reminder to Travellers (PDF file, 267 KB) and the Canadian Air Transport Security Authority (CATSA)'s What Can I Bring page provide specific information regarding permitted types and quantities of liquids and gels.

Other restricted or prohibited items

For a list of items that are either strictly regulated or forbidden as checked or carry-on baggage, please refer to the Restricted and prohibited items page.

The Canadian Air Transport Security Authority (CATSA)'s What Can I Bring initiative also offers useful information on what items can and cannot be placed in carry-on and checked baggage.

Travel to/from other countries

Canada's policy on prohibited items may vary from that of other countries. Travellers are urged to always check with local airport authorities for the most recent information for flights departing from other countries. The following websites also provide information on flights:


For your security, the United States Transportation Security Administration (TSA) screens all checked baggage belonging to passengers arriving in the U.S., connecting to other flights or continuing on the same flight. Screeners may open baggage as part of the screening process. If a bag is locked, the lock may have to be broken.

You may keep your bags locked. However, you must do so with the understanding that the screening process may result in damage to locks and/or baggage delays and that the TSA and the airline you are travelling with are not liable for any damage to locks that may result from this mandatory security measure. For more information, visit the TSA website.

Camera film

The equipment used for carry-on baggage at pre-board screening areas will not damage film with an ISO/ASA under 800. However, damage may occur if the same roll of film is exposed multiple times to a pre-board x-ray inspection.

Place undeveloped camera film as well as cameras containing undeveloped film in carry-on baggage, or take undeveloped film with you to the checkpoint and ask the screener to conduct a hand inspection.

The security screening equipment for checked baggage that is used by the Canadian Air Transport Security Authority (CATSA), as well as in airports in the U.S. and around the world, can cause damage to photographic camera film, but will not affect digital disks.
