New travel restrictions were introduced by the government of Canada
The government of Canada introduced new travel restrictions due to the worsening epidemiological situation in the country on January 15, 2022.
The government limited travel restriction exemptions for unvaccinated persons, allowing only a small proportion of unvaccinated persons to enter Canada. From January 15, 2022, unvaccinated or partially vaccinated travellers will not be permitted to enter Canada.
However, those exempted and will be allowed to cross the border include:
new permanent residents
temporary foreign workers in agriculture or food-processing occupations, and
children under the age of 18
Unvaccinated travellers are prohibited from entering, with some exceptions. Travel restrictions vary depending on from where the foreign national is departing. Therefore, travellers with any symptoms of COVID-19 will not be permitted to enter Canada.
Foreign nationals departing from any country other than the United States may be permitted to travel to Canada by air if they:
meet the fully vaccinated traveller exemption, or
are covered by any of the exemptions in the Orders (consult Travel restriction exemptions for those departing from a country other than the U.S.)
Foreign nationals are also permitted to travel to Canada if they have proof that they are fully vaccinated. Before departing from Canada, they must submit their proof of vaccination status via ArriveCAN.
Take note that whether departing from the United States or any other country, asymptomatic foreign nationals entering Canada must quarantine themselves, unless they have been fully vaccinated (or are exempt from quarantine requirements) and their arrival test is negative.
