Yes, you can fly within Canada without a passport if you are a Canadian citizen or a permanent resident, but you must provide valid government-issued photo identification. In 2026, the most common documents used for domestic travel are a Canadian provincial driver's license, a provincial health card (with photo), or a permanent resident card. If you do not have a piece of photo ID, you must present two pieces of non-photo government-issued ID, at least one of which must show your full name and date of birth (such as a birth certificate or a citizenship card). It is important to remember that the name on your ID must match the name on your boarding pass exactly. If you are a foreign national flying domestically within Canada, you are generally expected to use your passport as your primary ID, though a NEXUS card is also widely accepted. Note that this "no passport" rule only applies to domestic flights; if your flight has a connection in the United States or is traveling to an international destination, a valid passport is mandatory for all passengers.
