Security Screening Wait Times

CATSA encourages all passengers to arrive at their departing airport well in advance of their flight. Many airlines advise passengers to arrive two hours in advance for domestic flights and three hours in advance for US and international flights.

Planning a summer getaway?

If you plan to touch the sky during the busiest travel season of the year, we have some tips to help you to breeze through security.

Know your limits

sunscreen bottle

Many delays at security are caused by oversized liquids, aerosols and gels. When packing your carry-on, double-check that your sunscreen, insect repellent and all other liquid, aerosol and gel essentials are in containers of 100 ml or less and fit in a clear, resealable, 1 L plastic bag. If you bring a water bottle, make sure it’s empty before you get to security.

Certain liquids, such as medication and items for children under the age of 2, are exempted from these restrictions.


Sea salt in a scoop

Prepare your powders

Found a great artisanal salt? Bringing home some sand from your time at the beach? Be aware that certain powders and granular materials in your carry-on are limited to a total combined quantity of 350 ml or less, which is approximately the size of a soda can.

Pro tip: If you’re bringing checked baggage, placing all of your liquids and powders in there will take the guess work out of what can and cannot go in your carry-on AND you will be saving space for more important things in your carry-on…like snacks.
