Effective January 7, 2021, all passengers five years of age or
older will be required to provide a negative COVID test prior to
being able to travel by air to Canada. This applies to Canadians,
permanent residents and foreign nationals. This requirement was
announced on December 31, 2020.
Air travellers must take a COVID-19 molecular polymerase chain
reaction (PCR) test from an accredited lab within 72 hours prior to
boarding a flight to Canada. A passenger will not be allowed
to board without a negative PCR test result, and the test itself
must have done within the 72 hours prior to boarding the flight to
Canada.
There are very few exceptions to the COVID test
requirement. One exemption is for an "emergency service
provider", who is defined as someone providing services
"aimed at preserving life and property" in times of
emergency. It is not clear how travellers are supposed to
prove to the airline that they are under that exemption.
