Citizenship by descent: the strongest route, if you qualify
An EU parent or grandparent can make you eligible for an EU passport, the only route with full free movement. How to check, and why the rules keep tightening.
Every other route on this site gives you permission to live in one country, on conditions, for a period. Citizenship by descent is different: an EU passport gives you the right to live and work in any EU member state, indefinitely, with no employer, income threshold, or renewal. If you have a plausible claim, check it before you spend money on anything else.
Canada’s immigration history means a lot of Canadians have a claim and do not know it. Irish, Italian, Polish, German, Portuguese, Greek, Hungarian, Croatian, and Lithuanian ancestry are all common here.
How to check whether you have a claim
- Map the line. Which ancestor was a citizen of an EU country, in which generation, and on which side? Most schemes look at parents and grandparents; a few reach further back.
- Find out what happened to their citizenship. The usual killer is that the ancestor naturalised as Canadian before the next person in the line was born, breaking the chain. Dates matter more than stories.
- Read the rules as they stood then and now. Older nationality laws often discriminated by gender or by marital status at birth. Some of those rules have since been corrected, sometimes retroactively and sometimes not.
- Gather civil records early. Birth, marriage, death, naturalisation, and military records, from the right archives, in the right form. This is where the time goes, often a year or more.
Countries Canadians most often look at
- Ireland. The Foreign Births Register route, generally based on an Irish-born grandparent, with registration required before the next generation can claim.
- Italy. Historically the most generous route through unlimited generations, but Italy substantially tightened its descent rules in 2025, narrowing eligibility toward closer ancestors. Much of the advice online predates that change.
- Poland, Germany, Hungary, Greece, Croatia, Lithuania. Each with its own conditions, cut-off dates, and historical exceptions. Germany in particular has specific restoration routes for descendants of people persecuted under the Nazi regime.
- Portugal. It has both descent provisions and, separately, naturalisation rules that have been repeatedly revised.
Realistic expectations
- It is slow. Record-gathering plus consular or ministry processing is commonly measured in years, not months. Start it in parallel with whatever else you are doing.
- It is paperwork, not judgement. You either satisfy the statutory chain or you do not. A strong emotional connection to the country is irrelevant.
- Rules tighten more often than they loosen. Several countries have narrowed descent eligibility in recent years, and proposals to narrow it further appear regularly. If you have a claim under today’s rules, delay is a real risk.
- Dual citizenship with Canada is generally fine from Canada’s side, but confirm the other country’s position.
Verify before you rely on any of this
Nationality law is technical, country-specific, and changes (sometimes with retroactive effect). Confirm current requirements with the relevant country’s official sources and the consulate responsible for your province, and consider a lawyer who specialises in that country’s nationality law before committing time or money. Nothing here is legal advice.
