Many people worry about this. You pack your favourite cologne for a trip, then stand at the airport wondering whether security will take it away. Nobody wants to lose a bottle that cost good money. This is especially true when flying from or within Canada, where the rules are clear but strict.
The Canadian Air Transport Security Authority (CATSA) sets the rules for what you can bring through security. They are the ones who decide if your cologne stays with you or gets thrown in the bin. This blog answers the question: can you bring cologne on a plane?”
Every single container of liquid in your carry-on bag must be 100 millilitres or less. Not 110ml. Not 150ml. Not a 200ml bottle that is half empty. The limit is on the container itself. CATSA security officers look at the label on the bottle. If it says 150 ml, they will take it away even if only a few drops are left inside.
For cologne specifically, you can bring a bottle that is 100ml or smaller. That is about 3.4 fluid ounces. CATSA clearly states that cologne is a liquid, aerosol, or gel that must obey these rules.
All these small bottles must fit inside one single clear resealable plastic bag. The bag cannot hold more than 1 litre in total capacity. Think of a standard sandwich-size or quart-size Ziploc bag. That is the size you need. The approximate dimensions of a 1L bag are 15.24 cm by 22.86 cm or 20 cm by 17.5 cm.
You get exactly one bag per person. You cannot bring two bags of liquids. You cannot share space in your friend’s bag. Each passenger is allowed one 1L bag containing liquids, food, and personal items.
At security you must take this bag out of your carry-on and put it in the tray separately. Keep it somewhere easy to reach.
The rules do not say a specific number of bottles. But they say all bottles must fit in that one small plastic bag. In reality you can fit about 6 to 10 small bottles depending on their shape. Round bottles take more space. Flat bottles fit better.
For cologne, you can probably bring two or three 100ml bottles in one bag if you arrange them well. But honestly that is a lot of cologne for one trip. Most people bring just one bottle.
CATSA states that any containers over 100 ml or 100g can be placed in your checked baggage as long as they are not prohibited items.
The answer might surprise you, but cologne is a liquid. That is obvious. But other things count too. Aerosol deodorant counts. Hairspray counts. Sunscreen counts. Perfume oil counts. Even things like toothpaste and lip gloss count. CATSA has a long list of liquids that include shampoo, conditioner, mouthwash, perfume, cologne, liquid soap, insect repellent, creams, lotions, hairspray, and liquid-based cosmetics like mascara and liquid foundation.
If the product can spray, pour, pump, spread, or squeeze, it goes in the liquids bag.
Solid cologne is different. If you use a solid stick or solid balm-type cologne, that does not count as a liquid. You can put it anywhere in your bag with no size limit.
Checked luggage is much simpler. You can pack full-size cologne bottles in your suitcase on both domestic and international flights within Canada.
There is a limit, though. CATSA says aerosol items that are toiletry articles such as hair spray, perfumes, cologne, and aerosol deodorant are allowed in checked baggage. But each aerosol container cannot exceed 500 ml or 500 g. The total net quantity across all your aerosols cannot exceed 2 litres or 2 kg per person.
For non-aerosol cologne bottles, the same general rule applies. The total amount of liquids, gels, and aerosols in checked baggage usually cannot exceed 2 litres per passenger.
Make sure you pack cologne properly so it does not break. Wrap it in clothes or put it inside a sealed plastic bag.
Many people buy cologne at duty-free shops after security. They think because they bought it at the airport, the rules are different.
Here is the truth. The 100ml rule still applies to duty-free liquids on flights. But there is an exception. On certain routes, the government has allowed the use of Secure Tamper Evident Bags (STEBs) for duty-free liquids. These are special sealed bags with the receipt visible. If your cologne is in one of these bags, you may carry it through security at your connecting airport.
STEBs are available on certain routes. They are also available on all inbound Canada flights with a domestic or transborder connection.
But this option is not guaranteed. Every airport has its own rules, and the final decision is with the security officer. The safest option is to put duty-free cologne in your checked luggage before you board your connecting flight. If you are flying directly home with no transfers, even then it is risky.
Also keep in mind that Canada customs allows you to bring 1 litre of liquor or wine duty-free. Cologne is not counted in this allowance, but it is still subject to security rules.
This phase can be challenging for Canadian travellers. If you have a connecting flight, be cautious about buying cologne at the duty-free shop or carrying large bottles in your carry-on.
Air Canada and CATSA warn that if you are connecting through another airport and do not have access to your checked luggage between flights, you may not be allowed to carry duty-free liquids through security screening before boarding your next flight.
If you keep your purchases on your next flight, they must be in containers of 100ml or less and placed with your other liquids in one clear resealable 1L plastic bag.
| Flight Type | Carry On Limit | Checked Limit |
| Domestic within Canada | 100ml per container, all in one 1L clear bag | Aerosols max 500ml each, total 2L per person |
| International from Canada | 100ml per container, all in one 1L clear bag | Aerosols max 500ml each, total 2L per person |
| Connecting through another country | 100 ml per container unless in STEB bag | Pack in checked luggage if possible |
For flights within Canada or leaving Canada, the 100ml rule applies to all carry-on liquids. Your cologne bottles must be 100ml or smaller. All bottles must fit inside one clear 1L plastic bag. One bag per person.
For checked luggage, you have more room. Aerosols are limited to 500 ml each, with a total limit of 2 litres per person. Non-aerosol cologne bottles are generally fine, but pack them carefully so they do not break.
When in doubt, put it in checked luggage. That solves most problems. And if you are still confused, use the CATSA What Can I Bring tool before you fly. Better to spend five minutes checking than to lose your cologne at security.
