What is your status in Canada? Are you a ciitizen?I can’t afford the 3-night hotel stay. Can I be subsidized?
A person (who is not otherwise exempt from quarantine) who enters Canada by aircraft and cannot provide evidence of pre-paid accommodation at a government-authorized accommodation is considered unable to quarantine. A person who is considered unable to quarantine must follow the directions of a screening officer or quarantine officer to go to a federal designated quarantine facility.
