No smartphone or taking a short trip?
Within 72 hours of your arrival in Canada or before taking a short trip outside Canada, you can sign in to ArriveCAN from a computer to get your ArriveCAN receipt. Print your receipt and take it with you when you travel. You can also have someone submit your travel information on your behalf.
