Entry Requirements into Canada

Visitors must have valid travel documents to enter the country. Document requirements vary depending on which country you’re travelling from. For more information visit:

Note: Canada introduced a new entry requirement, known as the Electronic Travel Authorization (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 and sea) have not changed. Eligible travelers can apply online for an eTA. This entry is now mandatory, and travelers will need an eTA before they can board a flight to Canada.
