Liquid, aerosol or gel deodorant: 100 ml (3.4 oz.) or smaller container permitted in carry-on. Aerosol deodorant: These items are also subject to limits in checked baggage. Each passenger can bring a maximum of 500 ml or 500 g per container, with a total net quantity not to exceed 2 L or 2 kg per person.

According to Air Canada and CATSA (Canadian Air Transport Security Authority) regulations in 2026, the classification of deodorant depends on its physical form. Spray (aerosol), gel, and liquid roll-on deodorants are considered "liquids, aerosols, or gels" (LAGs). In carry-on luggage, these must be in containers of 100ml (3.4 oz) or less and fit into a single quart-sized clear bag. However, solid stick deodorant (the dry, waxy type) is not considered a liquid and can be carried in any size without being placed in the clear liquids bag. If you are packing aerosol deodorant in checked baggage, it is subject to a 500ml/500g per container limit, with a total limit of 2 liters per person. To save space and avoid security hassles in 2026, many frequent flyers on Air Canada suggest switching to solid sticks, which are exempt from the liquid volume restrictions and never leak in your bag during altitude changes.
