In March 2016, the Government of Canada introduced an ETA requirement for U.S. green card holders, as well as nationalities that were formerly visa exempt. U.S. citizens still do not require an ETA to enter Canada.
The Citizenship and Immigration (CIC) Canada has stated that the “leniency period” in which travelers can board their flight without an ETA will end on November 9. However, various reliable sources confirm that the ETA requirement will be strictly enforced by September 29. Hence, we highly recommend that all travelers to Canada check whether they require an ETA or a visa before traveling.
To find whether or not you require an ETA, please go to: http://www.cic.gc.ca/english/visit/visas-all.asp.
Please contact your Graham Adair representative if you have any questions.
