Visa Information Electronic Travel Authorization (eTA)

Canada has introduced a new entry requirement, known as an eTA, for visa-exempt foreign nationals travelling to Canada by air. Exceptions include U.S. citizens and travelers with a valid visa. Entry requirements for other methods of travel (land, sea) have not changed. Eligible travelers can apply online for an eTA. Travelers will need an eTA before they can board a flight to Canada. Find out more about Electronic Travel Authorization (eTA). ( Countries that are not eligible under eTA may need to apply for a Visitors Visa. To check online – go to and click “Visit” from the menu.
