British citizens living in Canada can no longer board a flight to the United Kingdom on a Canadian passport alone. Since February 25, 2026, airlines have checked every UK-bound passenger against the Electronic Travel Authorization (ETA) system, and that system does not issue ETAs to British or Irish citizens.
