UK tightens entry checks: Canadian dual citizens face possible "denied boarding" without the right documents

From February 25, 2026, the UK began strict enforcement of its Electronic Travel Authorisation (ETA) regime for non-visa visitors, shifting practical checks to the pre-departure stage as carriers are expected to stop passengers from boarding without an ETA, eVisa, or other valid documentation.

For most Canadians visiting the UK for short stays, an ETA is required. But the rules are more complicated for dual nationals: UK or Irish citizens (including dual citizens) cannot apply for an ETA and must instead prove their right to travel with a valid UK passport, a valid Irish passport, or a non-UK passport that contains a Certificate of Entitlement.

UK guidance warns travellers they may not be able to board without a valid document, and it notes that some people may be British automatically (for example, those born in the UK or with a British parent), which has contributed to last-minute confusion.

Canadian travel trade coverage describes cases where long-time Canadian residents born in the UK allowed their UK passports to expire and are now rushing to renew or secure alternative documentation ahead of trips.

Under temporary guidance, carriers may allow travel at their discretion if a traveller holds both an expired UK passport issued in 1989 or later and a valid passport from an ETA-eligible nationality such as Canada, provided the personal details match.

The Certificate of Entitlement option has drawn criticism over cost and processing, with UK reporting citing a £589 fee, while the Home Office says certificates will move to a digital format from February 26, making them a one-time application rather than tied to passport expiry.
