Learn about Airport Security

Being properly packed and prepared is the best way to get through security quickly and easily. 


London International Airport is always working to provide a safe and secure environment for travellers. Our airport works together with the Canadian Air Transport Security Authority (CATSA) and the Canada Border Services Agency (CBSA). 

The Right Way to Pack A Carry-On

Our airport works with our friends in CATSA to ensure only appropriate items are carried onto aircraft. Here is some important information to consider when you are packing your carry-on:

Make sure you can easily remove your laptop computer, film camera, and other large personal electronic devices from your bag, as you will have to take them out during the screening process. 

You can only bring liquids, aerosols and gels that are packaged in containers with a capacity of 100 ml/100 grams (3.4 oz) or less. You will need to pack all of these items in one transparent, resealable plastic bag with a capacity of no more than 1 L (1 qt). 

Many powders and granular materials are limited to a total quantity of 350 ml or less (examples include baby powder, foot powder, etc) so that they can easily  be taken out of your carry-on for inspection. 

You should pack any exempted liquids (baby formula, medication, etc) so that they can be easily taken out of your carry-on for inspection. 

You should avoid packing any gifts or souvenirs containing liquids, aerosols or gels in your carry-on, these kinds of items belong in your checked luggage.

Fragile items like eyeglasses, dishes, and figurines should be carefully packed in your carry-on so you can make sure the item doesn't get broken.
