17 Airport Snack Hacks vs. CATSA Rules at Toronto Pearson

Travel snack hacks are all over social media: skip the pricey airport food and bring your own. Good idea, as long as it gets through security.

Security screening in Canada is run by CATSA (the Canadian Air Transport Security Authority), not the TSA. The basic idea is similar to the U.S., but the details matter, and some popular hacks do not work at Toronto Pearson (YYZ). Here is how 17 of them compare with CATSA's own rules.

The core rule: solid or not solid

• Solid food is the easy part: sandwiches, apples, granola bars, crackers, muffins. CATSA says a food counts as solid only if it is solid at room temperature.
• Non-solid food is anything that can swirl, smear, scoop, spread or pour: yogurt, pudding, peanut butter, jam, soup, sauces and dips. It follows the liquids rule: containers of 100 mL / 100 g (3.4 oz) or less, all together in one clear, resealable bag of 1 litre or smaller, one bag per traveller.
• Powders and granular foods (like soup mix) are limited to 350 mL in total in your carry-on and may get a closer look.
• Canned food is allowed only if the liquid inside the can is 100 mL or less.
• More than 100 mL? Pack it in your checked bag. A screening officer always makes the final call at the checkpoint.

17 snack hacks, checked against CATSA's rules

1. Freezing a smoothie or yogurt solid

• The hack: Freeze a liquid or semi-liquid food overnight so it passes as a solid.
• At Pearson (CATSA): Not allowed if it is over 100 mL. CATSA says a food that is normally a liquid or gel will not pass in your carry-on even if it is frozen solid. Frozen foods must stay completely solid at screening, and anything that thaws into something you can pour or spread follows the 100 mL rule. Small containers (100 mL or less) are fine.

2. A frozen water bottle as an ice pack

• The hack: Freeze a water bottle to keep your snacks cold, then drink it once it melts.
• At Pearson (CATSA): Not allowed for this use. CATSA treats ice and the water inside ice packs, frozen or not, as liquids (100 mL or less). Gel and ice packs are allowed if you need them to treat an injury, or to keep things like baby food, milk, formula, water, juice or medication cold.

3. "Just add hot water" dry meals

• The hack: Pack instant oatmeal, dry noodles or powdered soup, then add hot water after security.
• At Pearson (CATSA): Mostly fine, with one limit. Dry noodles and oat flakes are solid foods. Powders and granular foods (like soup mix) are limited to 350 mL in total and can get extra screening. Ask a café for hot water once you are through security.

4. Hot meals in a thermos

• The hack: Pack a warm solid meal (rice, chicken, roasted potatoes) in an insulated thermos.
• At Pearson (CATSA): Fine if the food is solid. Soup, stew or gravy is non-solid and follows the 100 mL rule. If the officer wants to look inside, they decide.

5. A hot breakfast scramble

• The hack: Pack scrambled eggs with chicken and cheese in a thermos.
• At Pearson (CATSA): Generally fine. Scrambled eggs are solid at room temperature. The officer has the final say.

6. DIY bento and snack boxes

• The hack: Fill a divided tray with nuts, dried fruit, cheese cubes and dark chocolate.
• At Pearson (CATSA): Fine. These are solid foods. Keep any sauce or dip in a container of 100 mL or less, inside your clear bag.

7. Balanced bento meals

• The hack: Pack grilled chicken, rice balls, sweet potato and veggies.
• At Pearson (CATSA): Fine. Solid food goes through screening without the liquids rules.

8. Reusable travel utensils

• The hack: Carry your own cutlery so you are never stuck without a fork.
• At Pearson (CATSA): Forks and spoons are fine (plastic or metal). Knives are different: a blade of 6 cm or less is allowed in carry-on on flights within Canada, but on flights to the United States no knife of any size is allowed in carry-on.

9. The empty jar

• The hack: Bring an empty container to assemble a parfait or salad after security.
• At Pearson (CATSA): Generally fine. CATSA does not list empty containers as a problem, but the officer makes the final call.

10. Crunch-proof tubes

• The hack: Reuse an empty chip tube to protect a sandwich or fragile snacks.
• At Pearson (CATSA): Generally fine. A rigid, dry container with solid food inside is no problem.

11. A charcuterie box at 30,000 feet

• The hack: Pack hard cheese, cured meat and crackers.
• At Pearson (CATSA): Fine. Hard cheese and cured meat are solid. Spreadable cheese is non-solid: 100 mL or less, in your clear bag.

12. Low-maintenance dry snacks

• The hack: Roasted chickpeas, edamame, beet crisps, trail mix.
• At Pearson (CATSA): Fine. Dry snacks are the easiest option at screening.

13. Single-serve nut butter packets

• The hack: Use small squeeze packets instead of a full jar of peanut butter.
• At Pearson (CATSA): Fine if each packet is 100 mL or less and it fits in your 1-litre clear bag. CATSA lists peanut butter as a non-solid food.

14. Reusable silicone pouches

• The hack: Replace zip bags with leak-proof silicone pouches for fruit and snacks.
• At Pearson (CATSA): Fine for solid snacks. Your liquids bag, though, must be clear and resealable (1 litre or smaller), so keep a clear bag for those.

15. The takeaway bag trick

• The hack: Carry food in a paper takeaway bag to avoid carry-on limits.
• At Pearson (CATSA): Not a CATSA question. Carry-on limits are set by your airline, not by CATSA. Check your airline's rules before you rely on this.

16. Whole, uncut fruit

• The hack: Bring apples, oranges or bananas instead of buying fruit cups.
• At Pearson (CATSA): Fine at screening. Check the rules of your destination before you fly, since some countries, including the United States, have strict rules on fruit, vegetables and meat.

17. Keeping all your food in one pouch

• The hack: Put every snack in one easy-to-reach bag.
• At Pearson (CATSA): A good habit, not a rule. If an officer asks to look at your food, you can show it in seconds.

Rules can change, so check CATSA's pages before you fly: liquids, non-solid food and personal items and CATSA's food and snacks guide.
