Canadian law fully recognizes dual and even multiple citizenships. This means that individuals can become Canadian citizens without being required by Canada to give up their existing nationality. For many immigrants, this is a major advantage, allowing them to enjoy the rights and benefits of Canadian citizenship while maintaining legal ties to their country of origin.
However, dual citizenship is never governed by Canada alone. Whether you can legally hold two passports depends on the laws of both countries involved. Some nations strictly prohibit dual citizenship and require automatic renunciation, while others allow it freely or under specific conditions.
In this detailed guide, we look at 10 major source countries for new Canadian citizens in 2025 that allow dual citizenship with Canada, explain the rules that apply in each case, clarify which countries do not allow it, and outline the three main paths to becoming a Canadian citizen.
Canada’s Position on Dual Citizenship
Canada places no restrictions on holding more than one nationality. You are not required to renounce your original citizenship when you become Canadian, and Canada does not limit how many citizenships you can hold.
From Canada’s perspective:
- Dual citizenship is legal
- Multiple citizenships are permitted
- No declaration or approval is required
Once you become a Canadian citizen, you have the same rights and obligations as any other Canadian, regardless of how many passports you hold.
The key limitation comes from the other country’s laws, not Canada’s.
Why Dual Citizenship Rules Matter
Dual citizenship affects:
- Whether you must renounce your original nationality
- Which passport you must use when entering or leaving a country
- Access to consular protection abroad
- Military, tax, or legal obligations in your country of origin
Understanding these rules before applying for Canadian citizenship can help you avoid unexpected consequences.
Countries That Allow Dual Citizenship With Canada
Below are 10 countries whose citizens can legally hold dual citizenship with Canada, based on current laws and policies.
1. Philippines
The Philippines allows dual citizenship only for natural-born Filipino citizens.
Under Philippine law:
- Natural-born Filipinos who acquire Canadian citizenship can retain their Philippine nationality
- This is done by taking an oath of allegiance under Republic Act 9225
- No renunciation is required
Children born abroad to at least one Filipino parent are considered dual citizens by birth. These individuals must report their birth to a Philippine consulate to formalize their status.
Those who were not natural-born Filipino citizens may face limitations.
2. Nigeria
Nigeria permits dual citizenship with Canada, but only for citizens by birth or descent.
Key rules include:
- Nigerians who acquired citizenship at birth or through parentage may retain it after becoming Canadian
- Nigerians who became citizens through naturalization must renounce Nigerian citizenship if they acquire another nationality
Dual Nigerian-Canadian citizens are also required to:
- Enter and leave Nigeria using a Nigerian passport
This requirement is strictly enforced.
3. United States
The United States allows dual citizenship with Canada without restrictions.
US citizens can:
- Become Canadian citizens without renouncing US citizenship
- Hold both passports simultaneously
This applies whether US citizenship was obtained by:
- Birth
- Naturalization
- Citizenship by descent
US law requires that US citizens:
- Enter and leave the United States using a US passport
Canada has no objection to this requirement.
4. France
France has allowed dual citizenship since 1973 and imposes no conditions or restrictions.
French citizens can:
- Hold Canadian citizenship without renouncing French nationality
- Maintain multiple citizenships
France does not restrict travel, consular access, or nationality rights for dual citizens.
5. Pakistan
Pakistan permits dual citizenship with Canada under updated legislation.
In 2025, Pakistan formalized its dual citizenship framework through the Pakistan Citizenship (Amendment) Bill 2024, allowing Pakistani nationals to retain citizenship if they acquire nationality in approved countries.
Canada is on that approved list.
This means:
- Pakistani citizens can become Canadian citizens without renouncing Pakistani nationality
- This applies to citizenship obtained through naturalization or descent, if eligible
Pakistan restricts dual citizenship only to specific countries, but Canada is fully recognized.
6. Brazil
Brazil allows dual and multiple citizenship without conditions.
Brazilian nationals:
- Do not need to renounce Brazilian citizenship to become Canadian
- Can hold and use both passports
Brazil notes that holding multiple citizenships may reduce access to Brazilian consular protection in certain situations, but citizenship itself is not affected.
7. United Kingdom
The United Kingdom permits dual citizenship with Canada.
British citizens:
- Are not required to renounce UK citizenship
- Can hold both passports legally
However:
- Dual nationals must use a UK or Irish travel document to enter the UK
- The UK government does not provide diplomatic assistance to dual citizens when they are in the country of their other nationality
These are practical limitations, not legal barriers.
8. Germany
Germany significantly changed its citizenship laws in 2024.
As of June 27, 2024, German citizens:
- Are allowed to hold dual citizenship with Canada and other countries
- No longer lose German citizenship automatically when acquiring another nationality
Before this change, dual citizenship was allowed only in limited cases, such as:
- Citizenship by birth
- EU or Swiss naturalization
- Special permission to retain German nationality
- Citizenship by descent
The new rules make dual citizenship broadly accessible.
9. Syria
Syria allows its citizens to hold multiple nationalities.
Syrian citizens:
- Do not need to renounce Syrian citizenship when becoming Canadian
However:
- The Syrian government treats dual citizens as Syrian nationals first
- This applies in legal, administrative, and diplomatic matters within Syria
This can affect legal obligations and protections.
10. Mexico
Mexico explicitly allows dual and multiple citizenship.
Mexican nationals:
- Can acquire Canadian citizenship without renouncing Mexican nationality
- Face no conditions or restrictions
This policy has been in place since 1998 and remains unchanged.
Countries That Do Not Allow Dual Citizenship With Canada
Some countries strictly prohibit dual citizenship.
Notable examples include:
- India
- China
- Iran
Citizens of these countries must renounce their original nationality to become Canadian citizens.
Dual Citizenship for Indian Nationals
India does not allow dual citizenship under any circumstances.
If you are an Indian national:
- You must formally renounce Indian citizenship to become Canadian
- Holding both passports is illegal under Indian law
However, India offers the Overseas Citizen of India (OCI) status.
OCI status:
- Is a lifelong visa
- Allows visa-free travel to India
- Grants certain residency and economic privileges
- Does not grant voting rights or constitutional positions
OCI is not citizenship, but it provides a practical alternative.
How to Become a Canadian Citizen
There are three main pathways to Canadian citizenship.
Citizenship by Birth
Any child born in Canada automatically becomes a Canadian citizen, regardless of their parents’ immigration status.
Exceptions include:
- Children of foreign diplomats
- Children of consular officers or staff with diplomatic immunity
This rule applies nationwide.
Citizenship by Naturalization
Permanent residents can apply for Canadian citizenship if they meet all requirements.
Key criteria include:
- At least 1,095 days (three years) of physical presence in Canada within the last five years
- Filing income taxes if required
- No serious criminal prohibitions
- Intention to continue living in Canada
Applicants aged 18 to 54 must:
- Pass a citizenship test on Canadian history, values, rights, and responsibilities
- Demonstrate English or French proficiency at CLB level 4 or higher
A citizenship ceremony is the final step.
Citizenship by Descent and Bill C-3 Changes
Major changes to citizenship by descent took effect on December 15, 2025, under Bill C-3.
For Those Born Abroad Before December 15, 2025
- The first-generation limit has been removed
- Citizenship can pass through unlimited generations
- Lineage must trace back to a Canadian-born or naturalized ancestor
For Those Born Abroad On or After December 15, 2025
- Citizenship can pass beyond the first generation
- The Canadian parent born abroad must prove a substantial connection to Canada
- This requires at least 1,095 days of physical presence in Canada before the child’s birth
These changes significantly expand eligibility for Canadian citizenship by descent.
Canada remains one of the most dual-citizenship-friendly countries in the world. For citizens of many major source countries, becoming Canadian does not require giving up their original nationality. However, every case depends on the laws of the other country involved.
Before applying for Canadian citizenship, it is essential to:
- Confirm your home country’s dual citizenship rules
- Understand passport and travel requirements
- Be aware of legal and consular limitations
For many, dual citizenship offers the best of both worlds: long-term security in Canada and continued connection to their country of origin.
