The United States confirmed that Canadian travellers with mixed vaccines will be accepted when its land borders reopen to vaccinated travellers on November 8th.
Non-essential travellers crossing at a land border will be required to show proof of vaccination, and by January the same policy will apply to those deemed essential travellers.
Air travellers will also need to show proof of vaccination on arrival to the U.S., but will still need to show a negative COVID-19 test taken within three days of travel prior to boarding.
The Canada-U.S. border has been closed for non-essential travel since March 2020. Canada opened its border to U.S. travellers in early August.
