The detectors at the checkpoints are sensitive to metals. By avoiding clothing with metal appliqués, belts and jewellery, you will avoid the need for a physical search.
It is strongly recommended that you check the complete list of items that are and are not permitted by CATSA. Keep this link safe!
The measures for liquids are unchanged, i.e. only containers smaller than 100 ml are allowed and must be placed in a 1 L plastic bag.
Liquid disinfectants are accepted in carry-on baggage. Until further notice, a passenger may carry a 355 ml bottle of hand sanitizer in their carry-on baggage. The bottle does not need to be placed in the 1 L re-sealable bag with other liquids, aerosols and gels.
