Yes, you can bring food through airport security in Canada in 2026, provided you follow the CATSA (Canadian Air Transport Security Authority) guidelines regarding physical state and volume. Solid food items, such as sandwiches, burgers, whole fruits, granola bars, and cookies, are permitted in unlimited quantities in both carry-on and checked bags for domestic travel. However, non-solid foods (liquids, gels, and aerosols) like yogurt, peanut butter, jam, hummus, or maple syrup are strictly subject to the 100ml (3.4 oz) limit. These items must fit inside your single, clear, 1-liter resealable plastic bag. A key rule is that if a food item is "spreadable, pourable, or squeezable," it is treated as a liquid. If you are traveling internationally, particularly to the United States, be aware that while CATSA might let you through, U.S. Customs (CBP) has very strict rules about fresh fruits, vegetables, and meat products, which may be confiscated upon arrival. Always keep your food items easily accessible in case a screening officer needs to perform a manual inspection or a chemical trace "swab" of the containers.
