On March 15, 2016, Canada introduced a new entry requirement, known as an Electronic Travel Authorization (eTA), for visa-exempt foreign nationals traveling to or through Canada by air. This new requirement is mandatory from March 15, 2016 and travelers will need an eTA before they can board their flight to Canada. Exceptions include U.S. citizens and travelers with a valid visa.
A passport, a credit card, and email address are necessary to apply.

Quick eTA facts:
• Costs $7.00 Canadian
• Valid for five years or until a passport expires, whichever comes first
• Electronically links the passport used for travel
• Allows for multiple entries to Canada
