Customers travelling from Canadian and US airports may take with them in their cabin bag limited quantities of liquids, gels and aerosols, including travel-size toiletries such as shampoo, suntan lotion, creams, toothpaste, hair gel and hair spray. Containers holding liquids must not exceed three American ounces or 100ml.
Liquid containers must be carried in a separate clear plastic zip-lock bag that does not exceed 20 cm x 20 cm or 8 inches x 8 inches or a quart size. Items must fit in the bag comfortably and the bag must be completely closed. At the security search, the plastic bag must be removed from the cabin bag and x-ray screened separately.
