Can I Bring Continuous Positive Airway Pressure (CPAP) device on a Plane to Canada?

According to CATSA guidelines, the distilled water used by this device is exempted from the liquid restrictions. In order to have a CPAP device screened, passengers may choose to either: 1) bring a clear plastic bag to place the respiratory device into for screening or 2) leave the attachments (tubes and mask) inside the case and place the main electronic unit only in a bin. Documentation to support your medical needs or condition is not required; however, if you feel that it would help ease your screening, it should be presented to the screening officer along with your medically necessary items.
