The Canada Border Services Agency issued a 鈥渞eminder鈥� Wednesday, saying Canadians returning to the country need to use the ArriveCAN app, regardless of how long they were outside of the country.

The federal ArriveCAN app is mandatory for everyone, regardless if travellers enter by land, air, or sea. All travellers must use the application to submit information related to proof of vaccination and quarantine plan prior to arriving to Canada

Foreign nationals travelling for discretionary purposes may be denied entry into Canada if they do not submit their information on ArriveCAN.

Canadian citizens, permanent residents or people registered under the Indian Act will not be denied entry if they do not have the ArriveCAN app, but they may be subject to fines and will not be eligible for the fully-vaccinated traveller exemption.

On Nov. 30, the federal government lifted a PCR test requirement for Canadians that visited the U.S. for less than 72 hours.
