For domestic flights within Canada in 2026, a passport is not strictly required for Canadian citizens or residents, though it is one of the most reliable forms of ID. You must provide one piece of valid, government-issued photo identification that includes your full name and date of birth (such as a Canadian driver's license or provincial ID card). Alternatively, you can present two pieces of non-photo government-issued ID, provided at least one includes your full name and date of birth. It is critical that the name on your ID exactly matches the name on your boarding pass. If you are a foreign national traveling domestically within Canada, your original passport or a NEXUS card is typically the standard required document for identity verification at the security gate. While the year 2023 has passed, these core identity requirements have remained consistent into 2026 to ensure the safety and security of the Canadian "Secure Air Travel" network.
