Canada Entry Requirements for UK Citizens
Most visa-exempt British travellers flying to or transiting through Canada need an eTA linked to the passport they will use.
This guide is for the common case of a British citizen travelling to Canada by air for a short visit. Canada distinguishes between visa requirements and eTA requirements, and the answer can change with nationality, passport, route and purpose.
Flying to Canada
Visa-exempt travellers generally need an eTA when flying to or transiting through a Canadian airport.
Official application
Apply only through the Canada.ca eTA process and check the passport number carefully.
Land or sea arrival
An eTA is linked to air travel requirements; check the official Canada entry checker for land or sea routes and the exact passport.
Length and purpose
An eTA does not grant a right to work, study or remain in Canada beyond the period authorized by an officer.
Dual Canadian citizens
Dual Canadian citizens generally need a Canadian passport to fly to or transit through Canada.
The short answer
For the common case of a visa-exempt British citizen flying to Canada for a short visit, an electronic travel authorization (eTA) is generally required before boarding a flight to or transiting through a Canadian airport.
The eTA is linked to the passport used in the application. It is not a visa, work permit or guarantee of admission.
How to prepare
Use the official checker first
Canada’s official “Check if you need a visa or eTA” tool is the best starting point because it considers nationality, passport, travel method and purpose. Do not infer the answer from a friend’s passport or from a result for a different nationality.
Apply through Canada.ca
Use the official Canada.ca eTA page below. Check every passport digit before submitting. A typing error can cause a mismatch at check-in even when an application appears to have been approved.
If your passport changes, revisit the official guidance. The authorization is connected to the document details, so a new passport can require a new process.
Distinguish air travel from land and sea travel
Canada’s eTA requirement is primarily associated with flying to or transiting through Canada. A traveller arriving by car, bus, train or boat can face a different document process. This distinction is why the official checker asks how you will travel.
Keep the purpose of the trip within the rules
An eTA does not authorize employment, long-term study or residence. It also does not promise a particular length of stay. A border officer can assess admissibility and the conditions of the visit on arrival.
Check dual-nationality rules
Canada.ca specifically warns that dual Canadian citizens need a Canadian passport for air travel to or through Canada. If this may apply to you, resolve it before check-in rather than relying on an eTA linked to another passport.
A practical document checklist
- The passport used in the application
- eTA confirmation or application details
- Return or onward itinerary
- Accommodation information
- Evidence that explains the purpose and planned length of the visit
- Any work, study or family documents relevant to a different immigration route
Not every traveller is asked for every item, but a clear and truthful explanation avoids preventable confusion.
