21 Jul Can You Use a CPAP Machine on a Plane in Canada?
Travelling by plane doesn’t have to mean leaving your health routine behind. If you’ve ever wondered whether you can use your CPAP machine on a plane in Canada, the short answer is yes — and the rules are more traveller-friendly than you might expect.
Canadian aviation regulations recognize CPAP devices as medical equipment. This means airlines operating within Canada must accommodate passengers who depend on this therapy, whether on a short domestic hop or a longer international flight. Missing even a single night of treatment can disrupt sleep quality and leave you exhausted the next day — hardly the way to start a trip.
But knowing you’re allowed to bring your CPAP on board is just the beginning. Power access, airline policies, battery requirements, and security screening all come into play. Each carrier handles things a little differently, and being unprepared can turn a smooth journey into an unnecessary headache.
CATSA Security Screening for CPAP Travellers
The Canadian Air Transport Security Authority (CATSA) classifies CPAP machines as medical devices. Your CPAP machine does not count against your carry-on baggage allowance — you can bring it in addition to your standard carry-on and personal item. Air Canada, for instance, explicitly lists battery-powered CPAP and sleep apnea devices as permitted extras beyond the standard allowance.
At security checkpoints, remove your CPAP from its case and place it in a separate bin for X-ray screening, much like a laptop. You have two options: place the device in a clear plastic bag, or leave attachments like tubes and mask in the case and screen only the main unit separately. Security agents are trained to recognize CPAP equipment and handle it appropriately. They may also swab for explosive residues — a routine procedure for electronic medical devices.
One detail worth knowing before you pack: distilled water for your CPAP humidifier is exempt from standard liquid restrictions, according to the Government of Canada’s official travel page.
Documentation, Packing, and Hygiene Precautions
A doctor’s letter isn’t required to pass CATSA security screening — but carrying one can prevent delays. Some airlines, particularly on international routes, may ask for documentation. Keep a digital or physical copy of your CPAP prescription and the manufacturer’s compliance letter in an easily accessible pocket of your CPAP bag. Certain carriers specifically request a manufacturer compliance letter, so check with your device manufacturer about travel documentation options.
When it comes to packing, always keep your CPAP in your carry-on — never check it. The cargo hold is a harsh environment where bags get stacked, tossed, and exposed to extreme temperatures. Checked luggage can also be lost or delayed, and CPAP machines have sensitive motors and sensors that don’t handle rough handling well. A protective travel case adds an extra layer of security, and while overhead bins work fine, a dedicated carry-on keeps the device within reach during the flight.
For hygiene, leave your mask and tubing inside the bag during screening to keep them clean. Pack disinfecting wipes to clean the device after security agents handle it.
In-Flight CPAP Use and Battery Requirements
Most airlines permit in-seat CPAP use, but you should contact your airline at least 48 hours before departure. WestJet, for one, explicitly requires this advance notice. A window seat is often the best choice: it gives you something to lean against and keeps you clear of aisle traffic.
Don’t count on the seat’s power outlet. Not all outlets are designed for medical devices, so a battery pack is the safer option. For long flights, many international carriers require enough battery power to cover 150% of your flight time — so plan accordingly.
Transport Canada’s lithium-ion battery rules are worth understanding before you pack:
- Batteries under 100 watt-hours are generally permitted in carry-on without special approval.
- Batteries between 100 and 160 watt-hours require airline approval, with a limit of two per passenger.
- For CPAP devices specifically, the rules are more generous: no watt-hour limit on the installed battery, plus one backup battery up to 300 watt-hours — though CATSA recommends checking in with pre-board screeners beforehand.
- Lithium-ion batteries must always travel in carry-on, as they cannot be placed in checked luggage.
As for your humidifier, empty it completely before leaving home. Purchase distilled water after landing — separate bottles still fall under standard liquid restrictions at security.
