Travelling to Toronto
When you enter Canada, a Canada Border Services Agency officer may ask to see your passport and a valid visa, if one is necessary. For information about documentation required and border procedures please visit the Canada Border Services Agency's website.
Visa-exempt foreign nationals travelling to Canada by air require an Electronic Travel Authorization. Travellers with a valid visa and U.S. citizens are exempt from the eTA requirement and must carry proper identification such as a valid U.S. passport. For additional information, see the Government of Canada's web page: Find out about Electronic Travel Authorization (eTA).
Meeting and Convention Attendees: You may be asked for proof that you are attending a meeting or convention and it may be useful to have a copy of the meeting agenda and/or registration on hand. This may also be useful when returning to the U.S. should a similar question be asked.
