For British citizens building a future in Canada, one question comes up again and again: do I have to give up my British passport? The reassuring answer is no. Dual citizenship between the UK and Canada is fully permitted by both countries, which means you can become a Canadian citizen while remaining a British citizen for life. This guide explains how UK–Canada dual citizenship works in 2026, who can hold it, and the practical steps to get there.
Do the UK and Canada both allow dual citizenship?
Yes — and this is the crucial point for anyone worried about losing their roots. The United Kingdom places no restriction on holding another nationality, and Canada has formally recognised dual (and multiple) citizenship since 1977. Neither country asks you to renounce the other. In practice that means a Briton who naturalises as Canadian keeps both passports and both sets of rights.
- You do not need to renounce your British citizenship to become Canadian.
- You can hold and travel on both a UK and a Canadian passport.
- Children born to a Canadian parent may inherit Canadian citizenship even while holding British nationality.
You become a citizen second — resident first
There is no direct “apply for dual citizenship” form. You first become a Canadian permanent resident, live in Canada, and then apply for citizenship once you qualify. So the real starting point for most UK applicants is choosing the right immigration route to permanent residence.
The most common pathway for British professionals is Express Entry, while others arrive through a provincial programme, a work permit that leads to PR, or family sponsorship by a relative already in Canada. If you are at the very beginning, our overview of Canadian immigration programmes maps out the options, and our guide on how to move to Canada from the UK permanently covers the journey in depth.

The road to Canadian citizenship in 2026
Once you hold permanent residence, you can apply to naturalise as a Canadian citizen after meeting the residency and other requirements. The headline conditions are:
- Physical presence: be physically present in Canada for at least 1,095 days (three years) within the five years before you apply.
- Tax filing: have filed Canadian income taxes for the required number of years within that period.
- Language: demonstrate adequate English or French — usually straightforward for UK applicants as native English speakers.
- Citizenship test and oath: applicants aged 18 to 54 sit a knowledge test on Canada, then take the oath of citizenship.
A proposed change would let some time spent in Canada before becoming a permanent resident count toward the presence requirement, which can help people who studied or worked in Canada first. Because the rules continue to evolve, it is worth confirming your eligibility with a Regulated Canadian Immigration Consultant before you count your days.
What dual nationals should know about practicalities
Passports and travel
Once you are a dual citizen, Canada expects you to enter Canada on your Canadian passport, and you can continue to use your British passport elsewhere. Keep both current and store them safely — they are not interchangeable at every border.
Tax and pensions
Dual citizenship is about nationality, not a single tax bill. The UK and Canada have a long-standing tax treaty that prevents most people being taxed twice on the same income, but UK pensions, ISAs and rental income all need careful handling once you are resident in Canada. Many newcomers underestimate this; our article on UK pension tax when moving to Canada is a useful primer before you make the move.
Voting and obligations
As a dual citizen you can vote in Canadian elections once eligible and retain your democratic rights in the UK within the relevant rules. Your obligations — such as filing taxes correctly in your country of residence — apply in both directions, so good record-keeping matters.
Is dual citizenship worth it?
For most British movers, the answer is a clear yes. Holding both nationalities gives you the freedom to live, work and study in Canada permanently, access to consular support from two governments, visa-free travel on two strong passports, and the security of never having to choose between the country you came from and the one you have made home. It also keeps the door open for your children and future generations.
