Passengers entering Israel from abroad are required to quarantine for 14 days, if they are coming from a Red country. Those arriving from Green countries are exempt from quarantine.
For the past several months, Canada has been a Green country. Now, due to rising Covid infections in Canada, Israel has designated Canada as a Red country. This change will take effect at midnight on November 17, i.e the night between Monday November 16 and Tuesday November 17. Passengers landing in Israel before this time will be exempt from quarantine, while those arriving afterwards will be required to quarantine.
