In order to prevent the spread of the COVID 19 virus, the Canadian government has adopted new protective measures concerning passengers in international traffic.
As of November 21, 2020, all air passengers whose final destination is Canada will be required to provide appropriate travel information, contact, and a self-isolation plan for 14 days before they board their flight, through the "ArriveCAN" application, which is available as a mobile application or signing online, as a secure and easy way introduced to help passengers comply with these border measures.

Passengers entering Canada by land or overseas from November 21, 2020, must provide certain information through the said application. Within 48 hours of arrival in Canada, all passengers are required to confirm that they have arrived at the place of quarantine or isolation, and must complete daily self-assessment of COVID 19 symptoms for a period of 14 days.
Penalties for non-compliance with measures range from verbal warnings to a fine of C $ 1,000.
