Canada is now going to reopen its borders for international tourism, starting September 7. According to the Canadian government, borders will reopen for international tourism, provided that the domestic epidemiological situation remains favourable. For fully vaccinated travellers, there is a good chance that you will be able to travel to Canada in the month of September.
The country is actually going to kick-off the border reopening plans on August 9 by permitting American citizens and permanent residents, and those that are fully vaccinated, to enter the country for non-essential travel.
It has been reported that travellers must use ArriveCAN, in either web or app version, so as to submit travel information. This will allow them to know whether they are eligible to enter into Canada, and will determine whether or not they have to quarantine in Canada upon arrival. Fully vaccinated travellers are not required to quarantine upon entry.
