If you are leaving on a jet plane to America, Canadians and other foreign travellers will be required to get a COVID-19 test no later than the day before their departure.
The change is expected to take effect early next week.
This is part of a number of measures by U.S. President Joe Biden to keep a lid on the spread of the Omicron variant. In the briefing presented by the White House late Wednesday, there was no mention of borders, or whether fully vaccinated Canadians heading stateside by land would be required to show a test result.
At the moment, the U.S. requires fully vaccinated visitors arriving by air from Canada to get tested no more than 72 hours before leaving, while there are no test requirements for those using border crossings.
The new variant triggered updated travel restrictions by Ottawa last week, which require all foreign air travellers, except Americans, to get tested upon arrival and self-isolate while awaiting the results.
U.S. citizens were allowed to enter Canada back in September, though the federal government requires fully vaccinated travellers and Canadians returning home to provide proof of a recent negative COVID test. Canadians who have been in the U.S. for less than 72 hours are not required to show proof of a PCR test.
