Air mattress

You can bring an air mattress through airport security in Canada, however, it must be deflated and packed in your carry-on or checked baggage. Additionally, if the air mattress has built-in batteries, there are specific guidelines you need to follow:

• Battery type and size: Ensure the built-in battery is a lithium battery with a watt-hour (Wh) rating of less than 100 Wh. If the battery is between 100 Wh and 160 Wh, you can still bring it, but you will need approval from the airline.
• Carry-on vs. checked baggage: Batteries with a rating of less than 100 Wh can be carried in both carry-on and checked baggage. However, batteries between 100 Wh and 160 Wh are generally allowed only in carry-on baggage and require airline approval.
• Safety precautions: Make sure the battery is properly installed in the device. If you have spare batteries, they should be individually protected to prevent short-circuiting. This can be done by keeping them in their original packaging, placing tape over the terminals, or using a protective case.

If you have any specific concerns or questions, it's always a good idea to check directly with your airline for the most up-to-date information.
