ArriveCAN

ArriveCAN still contains Advance CBSA Declaration, which allows you to answer customs and immigration questions up to 72 hours in advance of flying into Canada. It is currently available to international air travellers who enter Canada at selected airports.
By submitting your customs and immigration information in advance, you will spend less time at a primary inspection kiosk (P*K) or eGate when you arrive at the airport. This contributes to shorter line-ups in arrivals halls.
At the border, you will be prompted to scan your travel document at a primary inspection device and confirm your identity. Once your identity has been confirmed, your Advance CBSA Declaration will be retrieved from ArriveCAN for you to review and certify. If changes are required, you can edit and update your declaration prior to certification.
Use of the Advance CBSA Declaration feature of ArriveCAN is entirely optional.
