For domestic flights within Canada in 2026, passengers aged 18 and older must present valid government-issued identification at the boarding gate. This can be one piece of photo ID (like a driver's license, passport, or permanent resident card) that includes your full name and date of birth. Alternatively, you can use two pieces of non-photo ID, provided at least one shows your name and date of birth. All names on your ID must match the name on your boarding pass exactly. Digital IDs are increasingly accepted in some provinces, but carrying physical copies is a high-value "backup" strategy. For children under 18, ID is generally not required for domestic travel, though having a birth certificate on hand is a premier safety measure.
